1 Planner Aug 20 T: Variables D : Identify Independent, Dependent and Control Variables Table of Contents 8/12 Claims and Evidence 2-3 8/13 Lab Safety 4-5 8/14 Questions 6-7 8/15 What is Science 8-9 8/16 Paper Tower /19 Discussions /20 Variable Vocab Get Out… Agenda, folder, and notebook DO NOW page 14- Lisa asked the question "Does Rogooti (a hair cream sold on TV) affect the speed of hair growth (in length)". Circle the cause and underline the effect in the question. How are they related?

2 Discussion Guidelines

3 Science fiction author Kim Stanley Robinson "We are the consciousness of the universe, and our job is to spread that around, to go look at things, to live everywhere we can. It's too dangerous to keep the consciousness of the universe on one planet; it could be wiped out. Mars will always remain Mars, different from Earth, colder and wilder. But it can be Mars and ours at the same time. And it will be. There is this about the human mind: if it can be done, it will be done. We can do it, so we will do it. So we might as well start."

4 Response I agree with Kim Stanley Robinson. He said that as humans the highest level thinking beings we are aware of, we have a responsibility to ensure the survival of our race. “There may be diseases, there may be nuclear conflict or there may be an impact by a very large asteroid that endangers the human race. Stephen Hawking says we have about 200 years. I think we could make it to another planet in less than 50 years.” Buzz Aldrin

5 Buzz Aldrin, second man to walk on the moon, said, “They will realize that they will go down in history. The pilgrims were a big step, too. Columbus was a big step. Magellan was a big step.”

6 Moving to Mars Discussion What went well and what didn’t? How would you change the discussion in the future to improve it?

7 Main IdeaDetail 1. VARIABLE  something that can change or be changed 2. INDEPENDENT VARIABLE (IV)  cause variable – what is being tested  changing this variable may cause an effect  ex: Amount of studying (IV) affects test scores. 3. DEPENDENT VARIABLE (DV)  effect variable – the result of the test  this variable is affected by a change in another variable  ex: Amount of studying affects test scores (DV).

8 4. CONSTANT (CV)  also known as a “controlled variable”  these are variables that could affect the result but are not the tested variable (IV)  keeping these values constant allows for a fair test of the IV 5. CONTROL GROUP  a version of the IV that is in the normal or untreated state 6. EXPERIMENTAL GROUP  other versions of the IV that are different from the control group  the different versions of the IV that are being tested

9 Create a mnemonic device on page 14 to remember the meaning of the words IV, DV, and CV

10 Exit Ticket 1.Explain why the Control Variables need to remain the same in each test. 2.How are Independent and Dependent Variables different from each other?
