3. When designing an experiment, scientists need to think about variables. o A variable is any factor that can affect the result of an experiment.

5. Read the information below and then answer the questions. SpongeBob loves to grow flowers for his pal Sandy, who loves big, colorful flowers. He found a new brand of seeds coated with a special “ booster ” fertilizer that said it would produce huge flowers. He planted 5 of the new seeds in one container and 5 of the old brand of seeds in another container. He placed both containers on a sunny windowsill and watered them every day. He measured the diameter of each flower, which is shown in the chart. 1.Which group was the control? 2. What is the independent variable? 3. What is the dependent variable? 4.

7. hypothesis vs theory vs law Law: a statement of fact: true, simple, universal, absolute (often from nature) Theory: what one or more hypotheses become once they have been verified and accepted to be true Hypothesis: a educated guess based on observation The biggest difference between a law and a theory is that a theory is much more complex and dynamic. simple analogy can be made using a slingshot and an automobile.
