SpongeBob Answer Key:

1 - Patty Power Which people are in the control group? Group B What is the independent variable? New sauce What is the dependent variable? Amount of gas What should Mr. Krabs’ conclusion be? The new sauce appears to work as it reduced the amount of gas produced 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 as a result thought that they didn’ t have as much gas. (Placebo effect) 2 – Slimotosis What was the initial observation? Slimotosis on Gary’ s shell What is the independent variable? Cures (Seaweed and Dr. Kelp) What is the dependent variable? Slime and odor What should Sponge Bob’s conclusion be? Although Gary’s symptoms have disappeared, it is not known which cure was the one that worked. He should redo the experiment and include a control group as well as two other testing groups for each of the proposed cures. 3 – Marshmallow Muscles Which person is in the control group? SpongeBob

What is the independent variable? Muscle cream

What 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 two weeks, it does not appear that the claims for the special muscle cream are true. If the claims were correct, we should have seen Patrick’s amount double, but not SpongeBob’s amount. The improvements were likely a result of Larry’s special workout. 4 – Microwave Miracle What was Patrick’s hypothesis? He hypothesized that feeding fish microwaved food would make them become smarter. Which fish are in the control group? The fish that eat regular food What is the independent variable? Microwaved food

What is the dependent variable? Time required to complete the maze Look at the results in the charts. What should Patrick’s conclusion be? According to the data, all but two fish in each group decreased their time through the maze. The special food does not appear to be a big factor in helping fish become smarter.

9/21/15: 1) Complete the situations on the control and variable worksheet. 2) Quiz on Friday on scientific method.

9/18/15: Quiz on scientific method on Friday. You must know all the steps and be prepared to match them to a situation.

9/16/15: 1) Create your foldable and glue or tape it into the next clean page of your notebook. 2) Fire Drill Assignment: Read the following...

Fire drills are a mean to prepare us for a fire. It takes complete cooperation to execute a fire drill. It is school policy for no one to speak during a fire drill and there is a reason for that. In the event that it was not a drill, every person's needs to be under the same understanding in order to exit the building safely and effectively. It takes just one person to not do as instructed to change the situation from a safe exit to a risky one. If the rule is DON'T SPEAK, please be respectful and follow that rules as well as the others to ensure your safety and the safety of all around you. Thank you!
