Jell-O® Cell Model Background: A great technique that can be used to reinforce the size and structure of membrane bound organelles is the use of a Jell-O® Cell. This model is extremely helpful because it’s relatively cheap to construct and provides an excellent three dimensional view of a cell. Students find it difficult to visualize the cell. Most forget that they are walking around with trillions of these things inside them. The model is constructed with use of various food items. We suggest using a light colored Jell-o to allow for a transparent view through the cell you are about to construct. We suggest you avoid the urge to use green Jell-O for the plant since green is a difficult color to see through. Materials Needed For Organelles: Organelle Item Suggested Nucleus Hard Gum Ball Centriole Licorice in the shape of a “T” Endoplasmic Reticulum

Yellow Fruit Roll Strip

Ribosomes Single Color Sprinkles Golgi Bodies Green Fruit Roll Strip Mitochondria Red Jelly Beans Vacuoles Raisins Cell Wall Wax Paper Chloroplast Green Jolly Rancher or Green Skittle Nucleolus M & Ms

Name ______________________ Date _________________________


Jell-O® Cell Model (cont.) Additional Materials Needed: -Non-stick Cooking Spray -8 oz plastic cups -Jell-O mix (light color) -Access to boiled water for making Jell-O -Plastic Spoon -Tooth Picks -Masking Tape Preparation:

1. Prepare the Jell-O as per the package directions. Spray the Non-stick cooking spray in each cup. Fill each cup halfway. Fill 2 cups for every cell you wish to create. If the directions require you to boil water, make sure cool the Jell-O prior to adding the mixture to the plastic cup so that your cups does not melt.

2. After Jell-O is prepared, slide the Jell-O out of the cups by using a plastic knife and running warm water around the edge. Your Jell-O should look like Figure 1 (below).

Figure 1 Figure 2

3. Cut Jell-O in half as shown in Figure 2. After the cut has been made, place top and bottom half piece flat side down on a plate.

4. Spoon out sections to place your organelles. Make sure to use the top and bottom half evenly this will allow you to distribute the weight evenly and make the cell more stable.

5. Using your masking tape, create a label for each cellular organelle. Attach the tape to a toothpick and label the cell parts. After the lesson, we recommend you remove the toothpicks and have the students place them on the correct organelles as a short quiz.
