Agenda: Do Now Writing a Problem How well do you observe? Qualitative vs. Quantitative Observations Checkpoint #1 12 Why / How? Why are the rocks in the middle of the river round­edged and the rocks on the side have sharper edges­­both consist of the same material? Why have the leaves of the plant on a windowsill turned toward the window after being there for a few weeks? 13 14 Senses!!! There are zebras and elephants in the picture. One zebra is drinking water, while the other one watches for preditors. The elephants are looking at the zebras. There are more elephants than zebras. 15 There are 2 zebras and 4 elephants. There are 6 animals in the picture. 1 zebra is drinking water. There is 1 "water hole".­­Thanks Charlie! There are 6 sets of ears, legs, and eyes, noses and mouths. 8 Tusks.­­ Thanks Bailey! 16 Ticket: Please write answers on notebook paper and be sure to put your name on it! Checkpoint #1 ­ I Can Statements 1 + 2 1. What is the purpose of the scientific method? Give an example of when you would use the scientific method. 2. Write the 8 steps of the Scientific Method in order. 17 Do Now: Write a problem for this situation: Sally is trying to get a stain out of her shirt. She needs to know which stain remover to use ﴾Type A or B﴿. Agenda: Do Now Qualitative vs. Quantitative Observations­­Review Observations from yesterday what type are they? Groups Hypothesis 18 Do Now: Without looking at your notes, explain the difference between Qualitative and Quantitative Observations. Give an example of each about the smartboard! Agenda: Do now Writing a hypothesis­­I Can #6 Review Tickets 19 Do Now: Write the steps of the scientific method in order! What 3 words always belong in a hypothesis? Agenda: Do Now Review Hypothesis Checkpoint Groups Target: Explain what a hypothesis is and write it in proper form. Review Targets: Differentiate between qualitative and quantitative observations. Write a problem in proper form. 20 Water boils faster at higher elevation. If the water is at a higher elevation, then it will boil faster. If the water is at a higher elevation, then it will boil faster, because lower air density. Hot water will boil faster. If water is warmer, then it will boil faster. If water is warmer, then it will boil faster, because the molecules are already moving fast therefore less energy is needed. 21 Shleboski got an A on his science test because he studied for 30 minutes everyday for 4 days prior to the test. Harry wants to be a better bike rider. He thinks if he rides 25 minutes each day he will get better and be able to do jumps like Grant. If one studies prior to a test then one has a better chance of getting a better grade because they have more practice. 22 Checkpoint #2 ­­I Can Statement 3­6 1.) Explain the difference between qualitative and quantitative observations. Tell if these observation are qualitative or quantitative: *There are 10 pens on my desk._________________ *His hair is brown.______________ 2.) A Problem is always in the form of a ______________________. 3.) Write a problem for the following observation: Betty wants to see if red or purple food coloring spreads faster. 4.) Write a hypothesis for the above situation. 23 Do Now: Write a hypothesis in proper form for this observation: "Hillary wants to see which dish detergent works better to wash her dishes­­Type A or B" Agenda: Do Now Work time for worksheet I Can # 7­9 Target: Compare Independent and Dependent Variables, Identify each of them, and Contrast Experiment and Control Groups. 24 Pore size Rate of flow ­ how fast the water flows Water going into rocks ﴾ type﴿, amount of pores, rock composition, pore shape. Type or Brand of Cleaner Cleanliness ­ How clean it gets amount of cleaner, how much dirt is on the window, cleaning utensil, window 25 practice 40 minutes practice 20 minutes practice 0 minutes practice 60 minutes practice 30 minutes 26 27 If muscle cells increase in size, then strength will be greater because of increased stimuli. Ind: Muscle cell size Dep: Strength Constants: exercise 28 Do Now: Answer the following: If I run 10 miles a day, then I will build strength in my leg muscles because I am working them a lot. Independent variable: Dependent variable: Constants: Agenda: Do now Go over example ﴾some classes﴿ What is a control group? Simpson's worksheet 29 /17 Group B, No juice Type Juice productivity Slime on shower water Type of spray Slime level no exposure to microwaves Microwaves Strength group of usual product Itch powder 30 31 32 33 Do Now: If you live with a cat, then you will be happier because you will have more companionship. IDV: DV: Control group: Experiment group: Agenda: Do Now Grade the Sponge Bob worksheet Update our grade sheet Collecting Data and Procedure 34 35 cake pan IV: Cake mix DV: Rising cake Constants (3): cooking time cooking temperature number of plants per unit of food IV: Plant food DV: growing of tomatoes Contants: light food amount IV: IV: DV: DV: Constants: Constants: 36 Do Now: 1. If you eat french fries ﴾bad food﴿, then you'll gain bodyfat because it is high in trans fat. Independent Variable: Dependent Variable: Constants ﴾3﴿: 2. Shumenski wanted to find out what kind of digestive enzyme would help break down broccoli best . Independent Variable: Dependent Variable: Constants ﴾3﴿: 37 If you live with a cat, then you will be happier because you will have more companionship. Independent variable: Number of cats Happiness Dependent variable: Control Group: People with no cats Experimental Group: 0 cats 2.5 People with 1 cat People with 3 cats People with 5 cats 1 cat 4.0 3 cats 6.75 5 cats 9.0 38 Distance Average time minutes by using stopwatch Distance (miles) Number of students 0­5 6­10 11­15 17 3 1 Average time (min) 7 10 25 39 40 I learned... If one lives a greater distance from school, then it will take them longer to get to school, because, they have a greater distance to travel. I learned that as one lives farther from school, it will take them longer. My hypothesis was correct. Peope who live farther away get to school faster. People who live closer get to school in a longer amount of time. 41 42 43 "Regular conclusion" 44 1.) Name the steps of the Scientific Method in order: 2.) What 2 things MUST be in the conclusion of your lab report? 45 46 IDV / DV Practice NAME:__________________ 1) If you eat 5 hamburger, then you will have more energy because they have protein in them. IDV: DV: Control group: Experimental group: 2) Shasta wants to find out how many laps it takes around the track to make her legs stronger. IDV: DV: 3) Luhoo drops 10 water drops on a quarter and wants to find out how many drops it will take for the quarter to get clean. IDV: DV: 4) If I do 25 pushups each day, then I will get bigger biceps because I am working them each day. IDV: DV: Control group: Experimental group: 5) If you look over your science notes 10 minutes each day, then you understand the material better because you are practicing.
