  1. Scientific Method Controls and Variables Part 1

  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?

  6. Bubble Yum Bubblicious Hubba Bubba Juicy Fruit Big League Chew Dubble Bubble

  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.
