Scientific MethodReview Game

Tables, charts, and graphs are often a part of which

step of the scientific method?

Analyze Results

The ___________ describes the steps you use during an

experiment.

Procedure

The part of the experiment that is used for comparison.

It is the part NOT being tested.

Control Group

List the 6 steps of the scientific method in order.

1. Ask a question2. Form a hypothesis3. Test the hypothesis

4. Analyze results5. Draw conclusions

6. Communicate Results

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 hypothesi

s

What three things are shown in the test the hypothesis

step?

1. Materials2. Procedures3. Variables

The one thing being tested and is therefore changed

between parts of the experiment is called the

_______ ________.

Uncontrolled Variable

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

For an experiment to be controlled, exactly how many uncontrolled variables must

you have?

Only ONE

For an experiment to be controlled, how many

controlled variables can you have?

Any number!

A short statement of whether or not your results support

your hypothesis is called a(n) ______________ .

Conclusion

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 best way to get rid of slimotosis?

What is the experimental question?

Seaweed treatment and Dr. Kelp

Name the uncontrolled variable(s).

No, too many uncontrolled variables.

Is this a controlled experiment? Why or why not?

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.

It is unclear which method caused the slimotosis to go away. He should conclude

that he must redo the experiment.

What should Sponge Bob’s conclusion be?

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.

He should test the two solutions on two groups of snails with slimotosis. He

should also include a control group.

How could Sponge Bob fix this experiment?

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.

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.

If the customers eat the new sauce, then their gas will go

away, because it contains a gas reduction ingredient.

Use the if…then…because format to say Mr. Krabs hypothesis.

Controlled. There is only 1 uncontrolled variable.

Is this a controlled or uncontrolled experiment? Why?

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.

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.

His hypothesis was correct, the new sauce helps

prevent customers from getting gas.

What should Mr. Krabs’ conclusion be?
