Essential Question: What is a controlled experiment? How
can we design and carry one out involving bacteria?
We will know we can answer these questions when we:
1. Know types of variables -independent, dependent, controlled/constantof a controlled experiment and correctly identify each variable
in examples.
2. Understands the purpose of the control group in an experiment
and can identify the control group in examples.
3. Can design and carry out an experiment including the following
parts: question, hypothesis, materials, procedure, and format for
data collection.
4. Correctly identify examples of the following types of faulty
reasoning: overgeneralization, personal bias, and illogical
conclusion.
5. Are able to write a conclusion and reflection for an experiment,
avoiding any faulty reasoning.

What is a hypothesis statement and how do I compose a wellwritten one?
• If I open the faucet [faucet opening size is the independent
variable], then it will increase the flow of water [flow of water
is the dependent variable].
Look back at your prediction for the paper airplane experiment.
Write your prediction below as a WELL-WRITTEN HYPOTHESIS.

Exposure to diet pills
Height of tomato plant
The tomato plants that did not get the diet pill
Type of dirt, amount of water, tap water, amount of sunlight
4 - he had four plants per pot
If tomato plants receive dissolved diet pills in their water,
then they will not grow as large because people lose
weight on a diet so plants might too.

1. Control Group -- Group B
2. Independent Variable -- Drink consumed
3. Dependent Variable -- #of stacks of papers stapled
4. What should Smithers' conclusion be? the special juice
doesn't work to improve work productivity
5. How could this experiment be improved?
6. What was the initial observation? Slime on the shower
Identify the7. Control Group - Side sprayed with water
8. Independent Variable - Spray used to clean (the coconut juice)
9. Dependent Variable - Appearance/amount of Slime
10. What should Homer's conclusion be? Coconut juice does not
remove shower slime.

Identify the11. Control Group - Mice not exposed to radio waves
12. Independent Variable - amount of radio waves they are exposed to
13. Dependent Variable - Strength of mice
14. What should Bart's conclusion be? Although the "radiowaved" mice
outperformed the control group, it was by a very small amount - 10%.
Therefore, he should probably run further tests.
15. How could Bart's experiment be improved?
Identify the16. Control Group - Subject A
17. Independent Variable - powder
18. Dependent Variable - length of itchiness
19. Explain whether the data supports the advertisements claims
about its product. -

Krusty Krab Breath Mints
1) Control = the people who received the mint
without the secret ingredient - group B
2) Independent variable = secret ingredient in
the mint
3) Dependent variable amount of breath odor
(bad breath)
4) Mr. Krab's can conclude that the breath mint
with the secret ingredient appears to reduce the
amount of breath odor more than half the time,
but it is not 100% effective.
5) possible placebo effect

Sponge Bob Clean Pants
6) SpongeBob's pants were not clean.
7) Independent variable = type of laundry soap
8) Dependent variable = amount of dirt left on
the pants (or how clean the pants were)
9) Sponge Bob should conclude that Clean-O
laundry soap does not appear to be effective in
cleaning his pants.

Squidward's Symphony
10) Independent variable = type of instrument played
11) Dependent variable = number of jellyfish that came
12) The clarinet did seem to attract a large number of jellyfish, but the average
number for the 3 trials also matched the average for the guitar. The flute attracted
the least number of jellys, but the average for this category is still larger than the
control.
Music seems to attract the jellys in greater numbers than when no music is played.
Therefore, Squidward's hypothesis that the clarinet attracts larger numbers of jelly
fish than other instruments is not proven by this experiment alone.
13) Based on the limited amount of information provided, it is difficult to tell if
Squidward's results are reliable. The description did not tell how long each break
was between trials. Did he leave enough time for the jellyfish to "clear out" of the
area? ETC

Super Bubbles
14) The ads claimed that the Super
Bubble solution would produce
bubbles that were twice as large as
those made with regular soap.
15) Independent variable = type of
bubble solution
16) Dependent variable = size of the
bubble (diameter)
17) Super Bubble = 15.1 cm
Regular Soap = 11.5 cm
Patrick should conclude _______.
Why???
18) Valid? Why or why not?
