Sink or Swim Splash Lab
Will it float or sink? Splash in and find out!
Will it float or sink? Your students predict, splash and explain. They feel water push back, build foil boats that carry the most cargo, and older students dissolve salt and sugar to make an egg float and liquids stack into a rainbow.

What's In Sink or Swim Splash Lab?
A hands-on workshop about floating and sinking: why do some things float and others sink? Every student investigates with a challenge card matched to your stage.
Every session opens with a surprise that has the class predicting what will float and what will sink, and ends with teams explaining what they found.
