Controls and Variables – Part 1SpongeBob and his Bikini Bottom pals have been busy doing a little research. Read thedescription for each experiment and answer the questions.1 - Patty PowerMr. Krabbs wants to make Bikini Bottoms a nicer place to live. He has created a new sauce that he thinks will reduce the production of body gas associated with eating crabby patties from the Krusty Krab. He recruits 100 customers with a history of gas problems. He has 50 of them (Group A) eat crabby patties with the new sauce. The other 50 (Group B) eat crabby patties with sauce that looks just like new sauce but is really just mixture of mayonnaise and food coloring. Both groups were told that they were getting the sauce that would reduce gas production. Two hours after eating the crabby patties, 30 customers in group A reported having fewer gas problems and 8 customers in group B reported having fewer gas problems.1.1. Which people are in the control group? 1.2. What is the

independent variable?1.3 What is the dependent variable? 1.4. What should Mr. Krabs’ conclusion be?1.5. Why do you think 8 people in group B reported feeling better?

2 – SlimotosisSponge Bob notices that his pal Gary is suffering from slimotosis, which occurs when the shell develops a nasty slime and gives off a horrible odor. His friend Patrick tells him that rubbing seaweed on the shell is the perfect cure, while Sandy says that drinking Dr. Kelp will be a better cure. Sponge Bob decides to test this cure by rubbing Gary with seaweed for 1 week and having him drink Dr. Kelp. After a week of treatment, the slime is gone and Gary’s shell smells better.2.1. What was the initial observation? 2.2. What is the independent variable?2.3. What is the dependent variable? 2.4. What should Sponge Bob’s conclusion be?

3 – Marshmallow MusclesLarry was told that a certain muscle cream was the newest best thing on the market and claims to double a person’s muscle power when used as part of a muscle-building workout. Interested in this product, he buys the special muscle cream and recruits Patrick and SpongeBob to help him with an experiment. Larry develops a special marshmallow weight-lifting program for Patrick and SpongeBob. He meets with them once every day for a period of 2 weeks and keeps track of their results. Before each session Patrick’s arms and back are lathered in the muscle cream, while Sponge Bob’s arms and back are lathered with the regular lotion.3.1. Which person is in the control group? 3.2. What is the independent variable?3.3. What is the dependent variable? 3.4. What should Larry’s conclusion be?

4 – Microwave MiraclePatrick believes that fish that eat food exposed to microwaves will become smarter and would be able to swim through a maze faster. He decides to perform an experiment by placing fish food in a microwave for 20 seconds. He has the fish swim through a maze and records the time it takes for each one to make it to the end. He feeds the special food to 10 fish and gives regular food to 10 others. After 1 week, he has the fish swim through the maze again and records the times for each.4.1. What was Patrick’s hypothesis? 4.2. Which fish are in the control group?4.3. What is the independent variable? 4.4. What is the dependent variable?4.5. Look at the results in the charts. What should Patrick’s conclusion be?

Answer Key1 - Patty PowerWhich people are in the control group? Group BWhat is the independent variable? New sauceWhat is the dependent variable? Amount of gasWhat should Mr. Krabs’ conclusion be? The new sauce appears to work as it reduced the amount of gasproduced in 60% of the people tested.Why do you think 10 people in group B reported feeling better? They thought they were getting the new sauce asa result thought that they didn’t have as much gas. (Placebo effect)2 – SlimotosisWhat was the initial observation? Slimotosis on Gary’s shellWhat is the independent variable? Cures (Seaweed and Dr. Kelp)What is the dependent variable? Slime and odorWhat should Sponge Bob’s conclusion be? Although Gary’s symptoms have disappeared, it is not known whichcure was the one that worked. He should redo the experiment and include a control group as well as two othertesting groups for each of the proposed cures.3 – Marshmallow MusclesWhich person is in the control group? SpongeBobWhat is the independent variable? Muscle creamWhat is the dependent variable? Amount of marshmallows lifted (strength)What should Larry’s conclusion be? Since both Patrick and SpongeBob improved their results by the end of twoweeks, it does not appear that the claims for the special muscle cream are true. If the claims were correct, weshould have seen Patrick’s amount double, but not SpongeBob’s amount. The improvements were likely a resultof Larry’s special workout.4 – Microwave MiracleWhat was Patrick’s hypothesis? He hypothesized that feeding fish microwaved food would make them becomesmarter.Which fish are in the control group? The fish that eat regular foodWhat is the independent variable? Microwaved foodWhat is the dependent variable? Time required to complete the mazeLook at the results in the charts. What should Patrick’s conclusion be? According to the data, all but two fish ineach group decreased their time through the maze. The special food does not appear to be a big factor inhelping fish become smarter.Note: Of the fish that did improve their times, the fish that were fed the special food averaged a 9.625 secondsdecrease in their times compared to an average decrease of 6.625 seconds in the fish group that received theregular food. This does show a slight improvement for the microwaved food group, but not enough to prove thathis hypothesis was correct. More testing would need to be done.
