Cells are integral parts of the human body, and they are usual subjects in elementary and high school biology. Teachers may require their students to bring a cell model at school, or they’re required to have one available for the class. A model cell helps students identify each part and function. If you want to know how to model a cell with modeling clay for a special project at class, here are the things you need to do.
- Ready the things you need. You’ll need differently-colored modeling clays, clay knife, and rolling pin.
- Make the cytoplasm. Grab a piece of clay and use the rolling pin to flatten it out. With your clay knife, trace a circle and cut it out. To help you with the colors, use light blue clay for this.
- Make the cell membrane. Get another piece of clay of a different color than that of the cytoplasm. Roll it like dough until you form a coil. Wound this around the cytoplasm. By now you’ll have a pizza-like shape with a thick crust surrounding it. Use red clay for this.
- Make the nucleus and membrane. Get a small piece of dark blue clay piece and roll it around. Get another piece and roll it like a coil before putting it around the circular one. Flatten out the middle area for a bit. It should fit the center of your cytoplasm without taking too much space.
- Make the endoplasmic reticulum. Grab another small clay piece, this time with an orange color. Roll it thinly before flattening it out like a belt. Grab the end and start folding it around the nucleus. The output should be just like your cytoplasm and cell membrane, but the outer edge is a bit squiggly.
- Make the nucleolus. Get a small piece of light blue clay and roll it into a ball. Place it on top of the nucleus, positioned slightly off the center.
- Make the smooth and rough endoplasmic reticulum. Get small pieces of yellow clay, rolled into small circles then flattened out. These are the smooth endoplasmic reticulum.
Use the bottom of a pen or pencil to make a circular indentation on top of the smooth endoplasmic reticulum. These will serve as the rough endoplasmic reticulum. Position them randomly around the cytoplasm. Three sets will do.
- Make the mitochondria. Grab violet colored clay and a light-yellow one. Roll the violet clay before flattening it out. Cut out two small oval shapes and set them aside. Cut off two smaller portions of the light-yellow clay and shape them like a belt. Arrange them in a zigzag pattern on top of the violet ones. Place the two mitochondrias on random positions around the cytoplasm.
- Make the Golgi apparatus. Get dark-colored clay and tear off small chunks. Roll them around into small circles. Put the circles beside each other until you have a cluster of small circles. Put the cluster on one side of the cell membrane.
Once you’re done with your cell model, print out the names of the cell parts that can be found on your model. Glue each name on a toothpick and stick it on each corresponding part.
