Mr. 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.

Identify the independent variable.

Identify the control group.

Johnny wakes up one morning. He swallows and thinks, “Man my throat hurts. I think I might have strep throat.” He tells his mom and she calls the doctor. At the doctor appointment, the doctor takes a sample from Johnny’s throat. The sample is sent to the lab. Later that day, the doctor’s office calls Johnny’s house with directions for Johnny to take antibiotics because he has strep throat.

Which of the following would be consider Johnny's hypothesis?

Which of the following would be consider the conclusion?

Patrick 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.
