Clouds are a large group of very small droplets of water or ice crystals, so light they can float in the air. All air holds water, but close to the ground it is generally in the form of water vapour which is an invisible gas. When warm air rises it enlarges and cools. Cool air is not able to hold as much water vapour as warm air, so some of the vapour condenses onto miniature pieces of dust that are floating in the air and forms a tiny droplet. When a large number of these droplets come together they develop into a visible cloud (Weather Wiz kids, 2010). Why do clouds appear white? Sunlight reflects onto the clouds and this is why they are white. Light is created by the colours of the rainbow and when they are all joined together they become the colour white. The sun looks to be a yellow colour as it gives out more yellow light than any other colour. Clouds reflect all the colours equally so they appear white. When the cloud becomes thick enough or high enough all the light above doesn’t make it through the cloud, this is why the clouds look grey or dark in colour. If there is a lot of a cloud together their shadow can add to the grey or multicoloured grey appearance (Weather Wiz kids, 2010). Clouds are grouped into four categories; this varies on the height of their bases above the ground. The four groups are cirrus, altostratus, altocumulus and storm. For more information about these clouds refer to Appendices (1). Why do clouds form at different heights in the atmosphere? Brian, 12: “The characteristics of clouds are dictated by the elements available, including the amount of water vapour, the temperatures at that height, the wind, and the interplay of other air masses” (Weather Wiz kids, 2010). Why do clouds float? A cloud is created from water drops. It takes shape when the air is heated by the sun. As the cloud rises, it cools slowly until it is gets to a state of total wetness and the water then compresses together, to form a cloud. The cloud floats if the air that it’s made of is warmer than the outside air around it (Weather Wiz kids, 2010). How do clouds move? Clouds move with the wind. Jet stream pushes along the high cirrus clouds. When thunderstorms occur clouds can travel at 30 to 40 miles per hour (Weather Wiz kids, 2010). 4 EDE305 Assessment 1SP2 2012 McLeod C Evaporation is when the sun heats up water in rivers, lakes or the ocean and changes it into vapour or steam. The water vapour or steam leaves the river, lake or ocean and goes into the air. Condensation occurs when water vapour in the air gets cold and changes back into liquid, forming clouds. Precipitation occurs when so much water has condensed that the air cannot hold it anymore. The clouds get heavy and water falls back to the earth in the form of rain, hail, sleet or snow. (Kidzone, 2012) Collection: When water falls back to earth as precipitation, it falls into the oceans, lakes or rivers or up on the land. On the land it will soak into the earth as “ground water” or it may travel over soil and collect in the oceans, lakes or rivers where the cycle begins again (Kidzone, 2012). Heat is needed to evaporate water from the surface of the Earth. Heat is released when water condenses to form clouds. Energy from thunderhead clouds can produce hail, harmful winds, torrential rain, lightning and sometimes tornadoes (National Geographic Society, 2012). How does rain form? Warm air forms water drops. As the warm air rises in the sky it cools. Warm air holds lots of water. In summer when it’s humid and enough water droplets gather together, they appear as clouds. When the clouds are large enough and have a lot of water droplets they hit together and form even larger clouds. When the drops become too heavy they fall because of gravity and we can then see and feel the rain (Weather Wiz kids, 2010). Part B – Transcript (Refer to appendix (2) 5 EDE305 Assessment 1SP2 2012 McLeod C Part C (1) Science ideas and thinking. The sky moves. Clouds turn grey and then go away as the sun makes them go white. Clouds sometimes turn black, grey or white. Clouds feel-fluffy, squishy, look like an igloo and the edges are rough. Clouds are made of rain and sun. The sun is made of hot larva. The earth is far away from the sun. The closest planet is mars. Third closest planet is earth. One side of the earth it hot like the desert. The other side of earth is so cold you can freeze to stone. Rain falls for the crops. Rain forms because we need it. Farmers need rain. Clouds make little/ big drops, turn grey then the drops fall. The noise from the clouds is made from thunderstorms and lightning. Rain, lightning thunderstorms fall from the clouds in the sky. When you look at clouds they look like they are moving. Some clouds cover the sun. Wind comes from the sky. (Refer to Appendices for Australian curriculum table (3) Part C (2) science concepts. Bella describes clouds as white and fluffy and understands and links them to elements of the sky (Australian Academy of science, 2005). Bella displays that she is able to observe the clouds moving and that wind is connected with the sky and that changes occur to clouds in the sky. Bella is able to describe the elements of the sky in her local environment (ACARA, 2011) (ACSSU019). Bella mentions that the “sky is moving” and later on in the interview says that “When you look at clouds they look like they are moving”. This shows that Bella is unsure if clouds do move or if they only look as though they are moving. Bella knows that wind comes from the sky but does not have knowledge or connect that clouds move with the wind. Bella has the concept correct in that 6 EDE305 Assessment 1SP2 2012 McLeod C the sky, clouds and wind all move in the sky but only has partial conceptual understanding of the wind moving with the clouds and that high clouds are moved along by the jet stream (Weather Wiz kids, 2010) (Campbell,2012). Bella has knowledge that the sun makes the clouds turn white. Bella has a partial understanding of this concept as they do reflect light from the sun. However she does not fully understand that light is created by the colours of the rainbow and when they are all joined together they become the colour white. (Weather Wiz kids, 2010) (Campbell, 2012). Bella recognises that the clouds can sometimes turn black or grey. And white clouds somehow connect with the light of the sun, but believe that clouds become grey when rain comes and doesn’t explain why she thinks they go black. Bella recognises that the changes in the clouds and sky affect the life styles of farmers, their crops and understands that we need rain to live (ACARA, 2011). Bella has some understanding about the sun, earth and the planet mars. Bella understands the effects of temperature when she explains, “one side of the earth it hot like the desert, the sun is also made of hot larva and the other side of earth is so cold you can freeze to stone”. And has some knowledge about distance when she says “The earth is far away from the sun, the closest planet is mars and the third closest planet is earth”. This gained knowledge is from a book that was read to her by her teacher a week earlier. Bella used transference of learning and prior knowledge of cloud processes and confidently explained scientific ideas to the interviewer. It also shows that Bella is a confident and involved learner that is able to communicate her thoughts (Campbell, 2012). Bella uses her senses when observing the clouds, communicating by describing the clouds as clouds “feel fluffy, squishy, look like an igloo and the edges are rough and that they move in the sky”. Also to describe the earth being hot like the desert and the other side of the earth being so cold you can “freeze to stone” (ACARA, 2011). 7 EDE305 Assessment 1SP2 2012 McLeod C Preconceptions. A1.Clouds feel-fluffy, squishy, look like an igloo and the edges are rough. A2.Clouds change colour as when the clouds turn grey and then go away as the sun makes them go white. A3. Rain, lightning, thunderstorms fall from the clouds in the sky. A3.The noise from the clouds is made from thunderstorms and lightning. A4.Clouds are made of rain and some out of the sun. A4 .Bella believes the reason for rain falling is for the crops. A4. Bella also believes rain forms because we need it. A4. Bella recognises that farmers need rain for their crops. One side of the earth it hot like the desert. The other side of earth is so cold you can freeze to stone. Interview Questions. The questions were not changed. Extra questions were added to gain more information. Bella’s first response was descriptive, the interviewer wanted to see if Bella had any more ideas or knowledge. Bella was asked “what else they look like”. Bella explored her sensory ideas and described the clouds as “feeling like they were next to her and that they looked like a jet plane”. Bella extended her thinking skills by comparing the clouds to an object and the distance between her and the clouds. The interviewer replied “it does look like a jet plane”. This extended Bella’s thoughts further, she described the clouds as “fluffy, squishy, they look like an igloo, kind of like the edges would be rough” showing that she is comparing shapes to known objects and the texture of the edge of the clouds and possible temperature. The interviewer noticed Bella watching her take a photo: “Would you like to take a photo of the clouds we are looking at with my camera?” “Yes” she replied, took two photos and continued with the binoculars. This was not planned ,it provided more interest, pictures for Bella to reflect on, to use for another lesson, to send home to show her family and in case it began to rain. The question: “How did you know all of that information about the sun and planets”?) Could not be planned. It was added for the interviewer to find where Bella had sourced her information. “A book my teacher read last week”. Bella used her prior knowledge from the book and displayed that she was interested in those topics. (Refer to Appendix: (2) transcript added questions and comments are highlighted in blue) 8 EDE305 Assessment 1SP2 2012 McLeod C Part D. ACTIVITY (1) Rationale –Bella’s preconception of how clouds feel was “Clouds feel-fluffy, squishy, look like an igloo and the edges are rough”. To extend her preconceptions and prior knowledge of clouds, Bella can learn about temperature, air, water droplets, vapour, texture and shape from the information on the chart and the experiment. Bella’s learning is influenced by located cognition indentifying learning as the understanding and skills gained in the situation that reveal the ways in which they will be utilised in actual life. (Campbell, 2012). This links to the National Curriculum: ACSSU019. Introduction – “In the interview you described clouds feel-fluffy, squishy, look like an igloo and the edges are rough”. As the page (A3) from the book “My Best Book of weather” is being read, Bella will match clouds to the information on the chart with Velcro. “Today we will create a cloud and see how it feels and what it is are made of”. Activity description Cloud in a bottle. Let’s talk through the instructions. Step 1 –pour rubbing alcohol into the bottle Step 2- swirl it around Step 3-Attach rubber stopper to the foot pump Step 4-insert rubber stopper into the bottle and pump 8-10 times Step 5 -quickly remove the stopper to watch the cloud form. Focus questions: What do you think is going to happen inside the bottle? Why do you think this is happening? Take the lid off quickly place your hand over the bottle and tell me how it feels. Are the edges rough? Is it squishy? What do you think clouds are made of? How do clouds rise up to the sky? (If needed also ask what is the temperature of the cloud then if Bella doesn’t understand is it hot/cold.) Write Bella’s responses on white board. 9 EDE305 Assessment 1SP2 2012 McLeod C Refer to number (4) Activity (1) in the appendix. Conclusion Ask Bella to circle any words that was written on the whiteboard before and after the activity that relate to the page information. Bella can then draw a picture of a cloud and write down how it feels. (Put cloud, A34 page, whiteboard photos and drawing on display. Watch Steve stranglers’ cloud experiment. http://www.youtube.com/watch?v=msSVQ903T8k ACTIVITY (2) Rationale – Bella’s prior knowledge of how clouds “turn white and grey then go away as the sun makes them go white”. To help Bella learn what created the colours white and grey in clouds using both incidental and intentional learning approaches (Campbell,2012) Bella will be learning with guided instructions, with her thoughts and comments combined to make a book with her new knowledge. Bella will be working towards these content descriptors from the National curriculum. (ACSSU019) (ACSSU032) (ACSHE034) Introduction “Today we are going to make our own book about how clouds become white and grey”.’ “We will go outside and stand under and beside the clouds to see if they are the same colour each side”. “You can take photos and they can be the pictures in your book”. “You can use a camera and binoculars to observe the colours and changes in the clouds.” “You can write your answers down on a sheet of paper in a clipboard”. “We will print your photos, comments and the questions you are asked about the clouds on the computer to create your book.” Activity description A cloud book Bella will be asked questions as she observes the clouds and explanations will incorporated 10 EDE305 Assessment 1SP2 2012 McLeod C throughout the interview. Bella will have guidance from the educator throughout the activity. Focus questions. What colour do the clouds look when we stand under them? Why do you think they look grey? (This is because sunlight does not shine straight on the bottom of clouds; they shine through the tops of clouds.) The bottoms of the clouds also look grey, if the cloud is a thick. Why does this happen? (Sunlight is more covered when the clouds are thicker. So the bottom of the cloud looks dark and grey.) Let’s wait until the cloud it passes, and look at its side What colour are the clouds when we see the side of them? What colour are the thin clouds? Why do you think they are white? (The side of the cloud will be light up by sunlight, and this is one reason why it is white So what have we learnt, the colours of the clouds depend on how much light is shining through them and the thickness or thinness of the clouds.) What appears in the sky that is colourful after the rain has stopped? Can you name any colours of the rainbow? (When the light from all the colours of the rainbow shines on the clouds what colour do the clouds become?) (When all the colours of the rainbow‘s wavelengths or "parts" of light are spread they become white.) 11 EDE305 Assessment 1SP2 2012 McLeod C Conclusion – Educator and Bella will read through the new book together to recap on the information. Bella can share her book with her classmates and family. A follow up - Make a rainbow experiment. (Refer to follow on activity number (5) activity (2) in the appendix. ACTIVITY (3) Rationale: This activity will extend Bella’s preconceptions and provide her with new information and understandings. Bella will learn that thunderstorms and lightning do not fall from the sky and how they are produced in the clouds. Bella will be working towards these content descriptors from the National curriculum. (ACSSU019) (ACSSU032) (ACSHE034) Introduction (Video tape, Lightning and thunder): http://www.youtube.com/watch?v=eMqw_pHhDY Explain that lightening is an enormous electrical flash. ”Have you seen sparks or heard crackling static electricity when they pull off a jumper or brushing your hair?” Ask Bella to shuffle along the carpet in her socks, and then touch a metal table leg, or the educator, and then ask if she felt a spark. Explain the spark is because of the build-up of positive and negative charges. “A cloud is made up of small particles of water and ice, bumping against each other.” “As they rub each other they make an electrical charge, just like when your feet rubbed against the carpet.” Activity description – (Video tape Bella). Lightning. Demonstrate with a battery the positive and negative points, the flashlight's connectors and switch. Ask her to press the switch and complete the circuit and the bulb will light up. “This happens with clouds as the positive particles rise to the top of the cloud and the bottom particles become negative.” “These are opposites that draw positive and negative charges. Lightning leaps from the bottom of the negative cloud to the top of the positive cloud.” “Sometimes the negative cloud leaps to the positive ground.” Completing an electric circuit this produces light energy” “It’s like turning on a giant torch “. 12 EDE305 Assessment 1SP2 2012 McLeod C Thunder Explain that lightning strikes cut channels through the air, making shock waves. It breaks and fills the channel. The air makes a clap of sound, this is called thunder. “So does the thunder make the noises in the sky?” Ask Bella to blow up a lunch bag, hold at the top to keep it closed. Then ask her to slap the bag between her hands and listen to the bag as the bag. Ask a child to slap the bag hard between his hands. Listen to the bang as the air is let out. Conclusion –Watch homemade video footage and then: http://www.youtube.com/watch?v=eMqw_pHhDY Bella can then draw lightning and thunder (have books on the table for her to refer to) Follow up: Ask Bella if lightning and thunder both falls from the sky? “Which one makes noise, thunder or lightning?” Read the book: I can read about Thunder and Lightning by David cuts’, and Bella can paint thunder and lightning. Display pages of the book photo’s of Bella and the painting on the wall. ACTIVITY (4) Rationale –Bella’s misconception is that “Clouds are made of rain and the sun”. Bella has new knowledge of rain, thunderstorms and lightning are all related to clouds .To understand how clouds are made Bella needs to learn how the water cycle works. This needs to be a visual and hands on lesson for Bella to gain a good understanding. Introduction – “Today we are going to learn about the water cycle. Watch http://www.youtube.com/watch?v=AQKdkponoZM&feature=related “We are now going to make our own water cycle.” Activity description – refer to Appendix (6) Talk through steps as Bella makes a water cycle jar. Step 1. Put in a cup of small rocks. Step 2. Put in a cup of sand. 13 EDE305 Assessment 1SP2 2012 McLeod C Step 3. Put in a cup of soil. Step 4.Put your plants in the soil Step 5.Place your bottle cap or shell of water in the jar. Put the jar in a sunny place and see how the water cycle works. Focus questions – Bella to write questions and answers on an A3 sheet of paper. What does the sun heat? Water evaporates from? What does water vapour form in the sky? Water vapour falls as to the ground? Water returns to the to start the water cycle again? Bella can draw pictures for each question on circled paper and make paper water cycle chart. Conclusion – watch and listen to song and clip http://www.youtube.com/watch?v=Zx_1g5pGFLI&feature=related Write out song A3 paper, to teach Bella. Display chart on wall with activities 1, 2 and 3 work samples. Reflect with Bella on her learning journey wall. 14 EDE305 Assessment 1SP2 2012 McLeod C References. ACARA, (2012).

They don’t make rain and are a sign of mild weather. They are typically made up of ice (National Geographic Society, 2012). “Alto-clouds have names as altocumulus or altostratus this depends on their shape and are a midlevel cloud. Altocumulus clouds are puffy and Altostratus clouds are flat, these clouds form n at very high levels in the sky. They usually signify a storm approaching .These clouds are able to make rain or snow that does not contact the ground this is called virga. Low-level clouds are normally thick, dark, and drizzly or snowy although they can also look like white fluffy cotton balls in a blue sky (National Geographic Society, 2012). Altostratus clouds are a blue-gray colour and are a mid level cloud made up of ice crystals and drops of water. These clouds cover the whole sky. In the thinner areas of the clouds, the sun may be faintly visible as a circular object. Altostratus clouds form previous to a storm occurring with nonstop rain or snow (Weather Wiz kids, 2010). Altocumulus clouds are mid level clouds that are made of water drops and look like gray puffy clumps that form in groups. If these clouds appear on a muggy morning and thunderstorms will arrive later that afternoon (Weather Wiz kids, 2010). Storm Clouds are called cumulus and cumulonimbus, or thunderheads. Cumulus clouds are fairweather clouds until they become large enough to create thunderstorms, and then they are called cumulonimbus. These clouds are produced by a flowing trail of hot air, which produces visible turbulence (havoc) on their higher surfaces. This makes the clouds look as though they are boiling (National Geographic Society, 2012). 16 EDE305 Assessment 1SP2 2012 McLeod C Cloud Chart Cloud Group Cloud Height High Clouds = Cirrus Above 18,000 feet Middle Clouds = Alto 6,500 feet to 18,000 feet Cloud Types Cirrus Cirrostratus Cirrocumulus Altostratus Altocumulus Low Clouds = Stratus Up to 6,500 feet Stratus Stratocumulus Nimbostratus Clouds with vertical growth Cumulus Cumulonimbus Special clouds Mammatus Lenticular Fog (2) Science understanding Australian curriculum links Science / Foundation Year / Science Understanding / Rain falls for the crops.

I have met her couple of times as I am visiting her class once a week before my practicum starts in October. To introduce this interview to Bella we had a sharing circle passed around the message stick at we all shared what we like to do on rainy days.”Bella said “I like to go to a restaurant “the students were all then ask to go and write about the things they liked to do on rainy days. Bella example is listed under appendix A I invited Bella out to look at some clouds with my binoculars and blanket. I also asked her if I could ask her some questions about the clouds in the sky. Bella was very happy to come outside with me. We discussed what a nice sunny day it was and both decided the best way to look at clouds would be to walk around the school to find the best spots. I explained to Bellas that we 18 EDE305 Assessment 1SP2 2012 McLeod C need to have the sun behind us to look at the clouds because if we looked directly at the sun with the binoculars we could hurt our eyes. Outside in the school yard. Coralie: “I will follow you”. Bella:”let’s go this way we can sit on this log” Coralie: “that will be perfect.” (We put our blanket over the log, I set up the binoculars for Bella making sure they were focused and that she could see). 1. Coralie: “Using these binoculars can you describe what the clouds look like in the sky?” Bella:”they look like white and they are fluffy, it, s like the sky is moving. Coralie: what else do they it look like? Bella: It feels, feels like the clouds are right next to you. (Bella then pointed to the cloud above her head as she held the binoculars) “It looks like a big jet plane”. Coralie; it does look like a jet plane. 2. Coralie: “How do you think these clouds become white?” Bella:”because sometimes when rain comes they become grey and when they go away they become white” 3. Coralie:“Why do clouds change colour?” Bella:”Because rain comes and they go grey then they go away and they turn white and the sun makes then go white.” Coralie; “The sun does make them appear white.”Let’s change spots and look at the clouds over here “I suggested. (We then walked across the oval alongside the school building until we came across a tree stump.) Bella: “We could sit here” Coralie: That’s a great spot to look at clouds we can both fit on the stump.” (Bella lifted up here binocolars and put them against her eyes to look at the clouds.) 4. Coralie: “If you could touch a cloud how do you think it would feel?”(Whispered in Areabella’s ear) Bella:”umm fluffy, squishy, they look like an igloo, kind of like the edges would be rough” Coralie: if they were igloo’s they would be very cold”. (I noticed Bella watching me as I took a photo of the clouds so I asked her if she would like a turn). 19 EDE305 Assessment 1SP2 2012 McLeod C “Would you like to take a photo of the clouds we are looking at with my camera Bella: yes” (I then showed her how to operate the camera). 5. Coralie: “What do you think clouds are made of?” Bella: “Some are made of rain, some out of the sun.”The sun is made of larva; the earth is far away from the sun.”The closest planet is mars and then the second umm I don’t know, the third on is earth that’s us on the one side it gets hot you go on the desert “and the other side you will freeze to stone it’s cold. Coralie; How did you know all of that information about the sun and planets? Bella:" A book my teacher read last week” Coralie: you have learnt’ and remembered a lot about the sun and planets, let’s walk around the other side of the school and see what the clouds look like around there, could you show me how to get there”? Bella: yes this way”. (Bella grabbed my hand a pulled me gently around the corner of the building.)No clouds here, let’s go this way. Coralie:”Great idea, I will follow you.”I followed Bella back to the oval on the other side of the building. Bella we can sit here with your blanket” Coralie: yes I like this spot “Bella sat down and pointed the binoculars at the sky. 6. Coralie:“What falls from the clouds in the sky?” Bella: “rain, lightning, umm humph I call it tears sometimes rain looks like tears.”Thunderstorms come from the clouds don’t they? “It’s nice looking at clouds there cool”. Coralie:”I like looking at them too“. 7. Coralie: “How does this happen and why?” Bella: “Rain falls from the crops ‘because we need the rain, farmers want rain clouds make little drops and big drops and when the clouds turn grey they fall”. Coralie: “that’s right they do” 8. Coralie: “Do clouds make sounds?” Bella:”Sometimes when thunderstorms and lightning come and make noise.” Coralie: "Yes they can be very loud”. “Let’s go and climb on that play equipment over there and see how the clouds look over there’. Bella:”We could sit on it” Coralie:"Great idea". 9. “What else do you know about clouds?” 20 EDE305 Assessment 1SP2 2012 McLeod C Bella:”They look nice, they feel like you are sitting on one, “sometimes they can turn black, when you look at them they look like they are moving and some clouds cover the sun”. “Wind comes from the sky.” (3) On a rainy day I like to go to a restaurant. “They look like white and they are fluffy, it, s like the sky is moving”. “Rain, lightning, umm humph I call it tears sometimes rain looks like tears.”Thunderstorms come from the clouds don’t they? “It’s nice looking at clouds there cool”. “Rain falls from the crops ‘because we need the rain, farmers want rain clouds make little drops and big drops and when the clouds turn grey they fall”. “It looks like a big jet plane”. 21 EDE305 Assessment 1SP2 2012 McLeod C (4) Activity (1) Cloud in a bottle: Materials: Foot pump Rubber stopper Rubbing alcohol Clear one litre bottle. Whiteboard with a table listed before and after the experiment. Camera to take photos during experiment and of whiteboard at the end. . During the experiment as we talk through the instructions. Step 1 –pour rubbing alcohol into the bottle Step 2-give it a swirl around Step 3-attach rubber stopper to the foot pump Step 4-insert rubber stopper into the bottle and pump 8-10 times Step 5 -quickly remove the stopper to watch the cloud form. Focus questions: (Write Bella’s responses on before and after table on the white board.) What do you think is going to happen to the rubbing alcohol in the bottle? Why do you think this is happening? When you take the lid off quickly place your hand over the bottle and tell me how it feels. Are the edges rough? Is it squishy? What do you think clouds are made of? How do clouds rise up to the sky? (If needed also ask what is the temperature of the cloud then if Bella doesn’t understand is it hot/cold.) Conclusion – Have you used the same words as before? Can you circle these words? Can you circle the words that you have said after the cloud experiment? Now can you draw a cloud and write how you think it feels. (Put photos on the wall and the photo of whiteboard and Bella’s artwork).

Cover the jar with the plate and wait a few minutes before you start the next step. Put the ice cubes on the plate. EXPLANATION: What happens? The cold plate causes the moisture in the warm air, which is inside the jar to condense and form water droplets. This is the same thing that happens in the atmosphere. Warm, moist air rises and meets colder air high in the atmosphere. The water vapor condenses and forms precipitation that falls to the ground. (5) Activity (2) Follow on activity. Making a Rainbow. MATERIALS: glass of water sheet of white paper the sun PROCESS: Step 1.Fill the glass all the way to the top with water. Put the glass of water on a table so that it is half on the table and half off of the table. Be careful that the glass doesn't fall. Step 2 makes sure that the sun can shine through the glass of water. Step 3 - place the white sheet of paper on the floor. Step- 4 Adjust the piece of white paper and the glass of water until a rainbow forms on the paper. 23 EDE305 Assessment 1SP2 2012 McLeod C (6) Activity 3 Follow on activity. MAKE LIGHTNING http://www.weatherwizkids.com/experiments-make-lightning.htm MATERIALS: aluminium pie pan small piece of wool fabric Styrofoam plate pencil with a new eraser thumbtack PROCESS: Push the thumbtack through the centre of the aluminium pie pan from the bottom Push the eraser end of the pencil into the thumbtack. Put the Styrofoam plate upside-down on a table. Quickly, rub the underneath of the plate with the wool for a couple of minutes. Pick up the aluminium pie pan using the pencil as a handle and place it on top of the upsidedown Styrofoam plate that you were just rubbing with the wool. Touch the aluminium pie pan with your finger. You should feel a shock. If you don’t feel anything, try rubbing the Styrofoam plate again. Once you feel the shock, try turning the lights out before you touch the pan again. Check out what you see! You should see a spark!! EXPLANATION: Why does this happen? It’s all about static electricity. Lightning happens when the negative charges, which are called electrons, in the bottom of the cloud or in this experiment your finger are attracted to the positive charges, which are called protons, in the ground or in this experiment the aluminium pie pan. The resulting spark is like a mini lightning bolt. WHAT IS LIGHTNING? MATERIALS: fluorescent light bulb rubber balloon PROCESS; Turn all of the lights off in the room. (The darker the better!) Rub the balloon on your hair for several seconds. Then hold the statically charged balloon near the end of the light bulb. This will illuminate the bulb. 24 EDE305 Assessment 1SP2 2012 McLeod C Repeat the demonstration as many times as desired. EXPLANATION: When you rub the balloon on your hair, the balloon builds up an electrical charge (static electricity). Touching the charged balloon to the end of the fluorescent light bulb causes the electrical charge to jump from the balloon to the bulb. This is what illuminates the light bulb. Lightning is an electrical discharge within a thunderstorm. As the storm develops, the clouds become charged with electricity. Scientists are still not sure exactly what causes this, but they do know that when the voltage becomes high enough for the electricity to leap across the air from one place to another, lightning flashes! Lightning can spark within a cloud, from one cloud to another, from a cloud to the ground, or from the ground to a cloud. (7) Activity 4.
