Sink or Float STEM Challenge: Candy Edition
The problem: You love to eat candy in the bathtub (that really is a problem!) but you are a little clumsy so you only want to snack on candy that will float if you drop it. How do you know which candies to buy?
Your Goal: Conduct tests to determine if several well-known candies sink or float in water.
