Some 3D animal cell project ideas to make at home include clay or Styrofoam cell models, edible cells with candy or Jell-o or kitchen scrap cells. Animal cell kits are also available for purchase from companies like Home Science Tools.
Cells made with Styrofoam and clay can be formed into spheres to demonstrate cell shape and depth. They may be kept for a long period of time, studied and labeled with toothpick markers. Clay cells can be made into ornaments to hang or paperweights. Cells made with edible treats use Jell-o and frosting as cytoplasm and candies for organelles. When building kitchen scrap cells, children can use plastic wrap for the cell membrane, a peach pit for the nucleus and candy sprinkles for ribosomes.
