6. Problem/Research/Hypothesis
Smithers thinks that a special juice will increase the productivity of workers.
Hypothesis format:
If the workers use the special juice, then their productivity will increase (# of stacks of paper).

7. Experiment
He creates two groups of 50 workers each and assigns each group the same task (in this case, they're supposed to staple a set of papers).
Group A is given the special juice to drink while they work.
Group B is not given the special juice.

8. Analyze
After an hour, Smithers counts how many stacks of papers each group has made.
Group A made 1,587 stacks
Group B made 2,113 stacks.

9. Conclusion
Group A is given the special juice to drink while they work. Group A made 1,587 stacks
Group B is not given the special juice. Group B made 2,113 stacks.
Therefore, we can conclude…

10. Conclusion
The special juice does not seem to improve productivity. It actually seems to make it worse!

11. Controls & Experimenting
Control Group:
Group B (not given the special juice)
Experimental Group:
Group A (given the special juice)

12. Identifying the Variables:
Independent Variable:
The special juice
Dependent Variable:
# of stacks of paper made

13. Line graphs- show change over time (2 sets of # data)
Bar graphs- graph amount of something in different categories (1 number, 1 category)

14. How is a Theory different from a hypothesis?

18. King Henry Died, (m) Drinking Chocolate Milk.
400 km = ________ m
400 x 10x10x10=
Or move decimal 3 to right
= 400.
= 400,000. m
