  2. Mr. Krabs

  3. Patty Power • Which people are in the control group? • Group B with 50 people with mayonnaise and food coloring for sauce. • What is the independent variable? • Group A with 50 people with new sauce. • What is the dependent variable? • Amount of gas reduced in the 100 customers. • What should Mr. Krabs’ conclusion be? • The new sauce reduces gas production with 30 out of the 50 people reporting fewer problems. • Why do you think 8 people in Group B reported feeling better?

  4. Slimotosis

  5. Gary is suffering! • What was the initial observation? • Gary’s shell has a nasty slime and gives off a horrible odor. • What is the independent variable? • Rubbing seaweed on Gary and Gary drinking Dr. Kelp for one (1) week. • What is the dependent variable? • Amount of slime gone and odor on Gary. • What should Sponge Bob’s conclusion be? • The slime is gone and Gary’s shell smells better but was it the seaweed rub or drinking Dr. kelp?

  7. Marshmallow Muscles • Which person is in the control group? • Spongebob is the control because his arms and back are lathered with regular lotion. • What is the independent variable? • Special muscle cream • What is the dependent variable? • Muscle power in two weeks. • What should Larry’s conclusion be? • Patrick’s muscle power increased by 15 in two weeks. • Spongebob ‘s muscle power increased by 12 in two weeks. • The new muscle cream did not double Patrick’s muscle power but did increase it.

  8. Microwave Miracle • What was Patrick’s hypothesis? • He believe fish that eat food exposed to microwaves will be smarter and would be able to swim through a maze faster. • Which fish are in the control group? • The 10 fish that eats the regular food. • What is the independent variable? • Special food (exposed to microwaves) • What is the dependent variable? • Amount of time to swim the maze.

  9. Patrick’s conclusion • The purpose of this experiment was to see if fish that eat food exposed to microwaves will become smarter and would be able to swim through a maze faster. Patrick’s hypothesis is correct. Fish 2 in the special group decreased his maze time by 34 seconds. Fish 2 in the regular food group decreased his maze time by 15 seconds. Special food fish had a 77 second decrease in speed overall. Regular food fish had a 33 second decrease in speed overall.
