Make an edible cell model using cake and candies. Bake or buy a round cake with a solid-color icing. Working from a textbook illustration of the inside of a cell, decorate the top of the cake. Use a muffin top or cookie to represent the nucleus in the middle. Place candies of different sizes and colors around the nucleus to represent proteins, chloroplasts, mitochondria and the other organelles.
Use colorful clay to make an animal-cell model. First, shape a half sphere to represent the cell. Form the different organelles using clay of distinct colors. Study the correct shape and proportional size of the organelles in science books before crafting your own. Add the clay organelles to the half sphere, observing their correct location. Identify the organelles by creating labels attached to toothpicks.
Make an edible animal cell with gelatin and fruit. Prepare a light-colored gelatin to represent the cytoplasm of the cell. Follow the instructions, using slightly less water. Place a clear plastic bag in a bowl, pour the gelatin into the bag and leave it in the refrigerator for one hour or so. When the gelatin is almost set, add fruit to represent the organelles. Use berries, grapes and fruit slices. When the gelatin has set, remove the plastic bag from the container.
Create an animal cell in a plastic bag. Use peas, beans, toothpicks, buttons, beads, pipe cleaners, leftover yarn and other materials to represent the organelles, placing them inside the plastic bag. Add two scoops of sodium polyacrylate to the bag and fill it with water. (The sodium polyacrylate polymer will cause the water to gel. Alternatively, use hair gel.) Use a plastic egg to represent the nucleus, and add pieces of string to represent the DNA. Seal the bag. The gelled water represents the cytoplasm while the bag is the cell's membrane.
