This projects
lets the student make an edible, 3-D model of an animal cell. The various organelles of the cell are represented by fruits
and candies. When you've finished making your cell and writing about it, you can eat it!
Make the
light-colored Jello or gelatin, but make it with a bit less water than the instructions call for (this will make the gelatin
a little stiffer and will make the cell components stay in place better). The gelatin will represent the cytoplasm of the
cell. First, heat the water to boiling (use about three-quarters of what is called for in the instructions). Dissolve the
gelatin in the hot water and carefully stir it. Carefully add the same amount of cold water.
Place an
open plastic bag (we used 1-gallon ziplock bags) inside a sturdy container (like a large bowl or pan) - this makes pouring
the Jello easier. Slowly pour the cooled gelatin into the bag - make sure that there is room in the bag for all the cell components
that will be added later. Seal the bag and put it in the refrigerator.
When the gelatin is almost set
(this takes about an hour, but depends on the temperature of your refrigerator), open the bag and start adding the components
of the cell.

Re-seal the plastic bag and refrigerate the gelatin until it is fully set.
When the gelatin is set, you can examine your 3-D gelatin cell but do not eat
it until it gets GRADED!!! |
