Foam Floaters

Foam Floaters lesson plan

  • 1.

    Collect a variety of recycled foam produce trays, margarine tubs and lids, and other safe containers. Ask families to recycle clean items.

  • 2.

    Experiment with items that float and sink. Ask children to think of reasons why things float or sink. Try out their theories.

  • 4.

    Construct something you think will float on water. Use only materials that can get wet such as craft sticks and foam produce trays. Cut aluminum foil, plastic lids, straws, or other items with Crayola® Scissors.

    Glue everything together with Crayola® School Glue. Dry overnight.

  • 6.

    Experiment using a water table or large containers of water. Which constructions float? Which ones sink? Why?

    If a construction sank, what could be changed to make it float? Try it.
