Scientific Method

1. Scientific Method Review Game

2. Tables, charts, and graphs are often a part of which step of the scientific method? Analyze Results

3. The ___________ describes the steps you use during an experiment. Procedure

4. The part of the experiment that is used for comparison. It is the part NOT being tested. Control Group

5. List the 6 steps of the scientific method in order. Ask a question Form a hypothesis Test the hypothesis Analyze results Draw conclusions Communicate Results

6. What step of the scientific method is this? “If I use place the basil in direct sunlight, then it will grow higher, because basil needs a lot of sun.” Form a hypothesis

7. What three things are shown in the test the hypothesis step? Materials Procedures Variables

8. The one thing being tested and is therefore changed between parts of the experiment is called the _______ ________. Uncontrolled Variable

9. When doing a medical drug test, one group received sugar pills while the other received medicine. What is the sugar pill group called? Control group

10. For an experiment to be controlled, exactly how many uncontrolled variables must you have? Only ONE

11. For an experiment to be controlled, how many controlled variables can you have? Any number!

12. A short statement of whether or not your results support your hypothesis is called a(n) ______________ . Conclusion

13. Sponge 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. What is the experimental question? What is the best way to get rid of slimotosis?

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. Name the uncontrolled variable(s). Seaweed treatment and Dr. Kelp

15. Sponge 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. Is this a controlled experiment? Why or why not? No, too many uncontrolled variables.

16. Sponge 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. What should Sponge Bob’s conclusion be? It is unclear which method caused the slimotosis to go away. He should conclude that he must redo the experiment.

17. Sponge 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. How could Sponge Bob fix this experiment? He should test the two solutions on two groups of snails with slimotosis. He should also include a control group.

18. What would be the benefit of having a control group when redoing the experiment. You can see if the slimotosis goes away on its own.

19. Mr. Krabbs 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. 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. Use the if…then…because format to say Mr. Krabs hypothesis. If the customers eat the new sauce, then their gas will go away, because it contains a gas reduction ingredient.

The group with the mayonnaise and food coloring.

Both groups were told that they were getting the sauce that would reduce gas production. 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. Name the uncontrolled variable(s). The type of sauce on the crabby patty.

22. Mr. Krabbs 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. 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. Is this a controlled or uncontrolled experiment? Why? Controlled. There is only 1 uncontrolled variable.

23. Mr. Krabs 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. 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. What should Mr. Krabs’ conclusion be? His hypothesis was correct, the new sauce helps prevent customers from getting gas.
