Float Trip

June 14, 2020

Why do some things float and others don't? 

Hannah Baker helps you navigate the waters and explore density, buoyancy and specific gravity in this Hershey's Lab experience that you can do at home.  

Materials | Supplies

  • large clear container
  • water
  • treats to test - cereal, candy, chocolates, gummies
  • aluminum foil
  • styrofoam
  • paper clips
  • popsicle sticks
  • pipe cleaners
  • toothpicks

Concepts Explored

  • density
  • buoyancy
  • specific gravity
  • prediction
  • experimentation

Discovery Starters

Why did some items sink and others float? 

What floated the best? Why?

Did the size of the treat matter? 

What happened when you removed the wrapper?

Explore Further

Look around you and predict what will float or sink based on your observations in this experiment. 

Next time you're in swimming, think about how you float or sink. What makes it easier to float?
