Concept Check: Intro. to Physics

1. What is the first step of the scientific process?

• Draw Conclusions
• Make a hypothesis
• Ask a question/Make observation
• Test the experiment

You are testing the buoyancy of a cotton ball . You leave one plain, cover half of one in oil, and cover the third in oil completely then place each in water. What is the Independent variable?

• Amount of water

• amount of oil on the cotton ball

• buoyancy of the cotton ball

• the plain cotton ball
