Scientific Method, Engineering Process, and Graphing

The reason we use the engineering design process is to

• Find a designer.

• Solve a problem.

• Increase energy.

• Make a profit.

A hypothesis is an educated guess that must be

• testable.

• correct.

• incorrect.

• unexpected.

What is the first step of the scientific method?

• Form a hypothesis

• Ask a question

• analyze data

• share results

The summary at the end of an experiment that explains the results is the... 

• conclusion.

• procedure.

• materials.

• responding variable.

I want to know if low strength bleach, medium strength bleach, or maximum strength bleach will get Heinz ketchup stains out of white T-shirts the best. What is the independent variable in this experiment?

• the type of stain

• the strength of the bleach

• the color of shirt

• the brand of ketchup

I want to know if low strength bleach, medium strength bleach, or maximum strength bleach will get Heinz ketchup stains out of white T-shirts the best. What is the dependent variable in this experiment?

• how well the stain is treated

• the strength of the bleach
