I never imagined that cell making could be creative, fun, and yummy. But here we have the 3 basic parts of a cell: cell membrane, cytoplasm, and the nucleus.
1 cup Lemon or Pineapple Jello (room temperture)
2" of a banana
1 ziploc sandwich bag
8" of string or yarn
Pour the 1 cup of jello into a bag, then add the banana. Have your little student identify the 3 parts of the cell. For fun you can split the banana to make 2 nuclei to show cell division. Use the string to place the banana pieces on different sides with the jello sort of equally divided.
