These flashy layered columns of household liquids make a colorful way to show how fluids with less density float on top of each other. Young scientists can also practice making hypotheses while testing where different objects will settle in the layers.
The Titanic Game! (Buoyancy with Aluminum Foil Boats)
This game is great to do on a playdate or family day. Kids will learn about what makes things float and sink, practice counting, and use creativity and fine motor skills. Younger preschoolers may need assistance with the initial construction piece, but all ages (moms and dads too!) will have fun building and sinking their boats!
