Success Criteria Can understand that light travels in straight lines. Activity (including differentiation) Light – Why learn about it? Take time at the start of this topic to establish with children why it is so important to know about light. For example, you could begin by imagining Earth without light that has been created by humans. How would this affect our lives? Use satellite picture of Earth at night time to show where in the world people rely most on created light. http://geology.com/articles/satellite-photo-earth-at-night.shtml Modelling – What evidence would prove that light travels in straight lines? Hook – A cartoon. Sketch a cartoon on the board showing a child on one side of the outside corner of a building shining a torch at night time. Around the other side of the corner draw his friend. In a speech bubble write; ‘The child cannot see the other one child because light from the torch cannot pass through the dark.’ In another speech bubble write: ‘The child cannot see the other child because the light isn’t powerful enough’. Finally, write in another speech bubble: ‘The child cannot see the other child because the light cannot travel around corners’. Ask the children to discuss the comments in the different speech bubbles. Ask them now to think of a way to prove or disprove that light cannot travel around the corner because it travels in straight lines. http://www.bbc.co.uk/learningzone/clips/demonstrating-how-lighttravels-in-straight-lines/1625.html The video above demonstrates how light can appear to travel in straight lines. Children can make their own model by: 1. For each index card, use a ruler to draw lines connecting opposite corners of the card. 2. At the intersection of the two lines, use a hole puncher to punch a hole in the centre of the index cards. 3. For each card, use a small piece of Plasticene and place the card in this to create a "stand" for the card. Place the cards so that they stand vertically and at an equal distance from each other. 4. Place the torch at one end of the row of index cards and turn off the light in the room. 5. Arrange the index cards so that light can be seen through all the holes. Recording The children can draw their model. They can add writing to their drawing in order to explain the path that the light takes. 2 Science Use the idea that light travels in straight lines to explain why shadows have the same shape as the objects that cast them. Modelling – How can we show why shadows have the same shape as the object that casts them? In pairs, one of the children can hold a small opaque square shape a few centimetres above a piece of white paper on a table surface. The other child can hold a torch above the square so that it shines down at it. The children can then use spaghetti to show the path of the light from the torch and around the square. They could draw the shape created by where the spaghetti has touched the paper (i.e. a square). To increase the challenge, ask the child to make another drawing on the paper of a square when the square shape is moved a particular distance towards the torch. Again, to extend the children’s thinking, ask them to make four small holes in their shape; one near each of the corners. Ask them to draw on the paper what they think the shadow of this object will now look like. They can then carry out the test to see if they were correct. Recording Through drawings, children can try and show the path that the light takes in order for the shadows to be formed. . Problem-solving – Where would we need to place the umbrellas so that the people around the pool have the most shade? Provide the children with a plan of a pool with sunbeds positioned around it. Indicate on the plan where east and west are. The children can begin by using Plasticene to make model people for the sunbeds. They can then use a torch to model the apparent movement of the Sun from east to west. Now provide the children with ‘umbrellas’ – these could be cocktail umbrellas. The children must work out where these umbrellas must be placed at different points in the day in order for the people on the sunbeds to have shade if they want it. Recording The children could take photos of their models. Using arrows and text, the children could explain how they have solved the problem. 3 Science To be able to explain that we see things Modelling – How can we show how we see things in a mirror? Set up a target on the board. Children asked to use light from a torch and a mirror in order for the light beam to hit the target. because light travels from light sources to Children could use two mirrors to view a mystery object on the table top from below the table/or try to use mirrors to read a post-it note on their back our eyes or from light sources to objects and then to our eyes. 4 Science To be able to plan a fair-test; recognising and controlling variables. Recording Children can draw and label diagrams to record the passage of the light beam in both activities. Encourage the children to use lines with arrows to represent the passage and direction of the light. • Small mirrors • Torches • Post-its • Blue tac • Mirror card • Sparkly shapes; confetti Fair-test investigation – Which materials is best at reflecting light? One way to test this is to place two piece of card vertically on pieces of blue tac. Shine the torch on one of the cards so that the light will be reflected on to the other card. Keep moving the card apart until you can no longer see the light reflected on the second card. You can measure this distance. Repeat this, but each time connects a different material to the first card. Recording Children could record their findings in a bar chart. Pattern-seeking – How can we increase the number of reflections? Hinge two mirrors together using some Blue tac. Place the object in front of the mirrors. The children can start by having a whole 180 degrees angle between the two mirrors. They must then continue by decreasing the angle by 10 degrees each time. Recording The children can record the number of reflections seen within a table. 5 6
