1. To make an animal cell for a school science project, the first thing you should do is to be sure of what you are asked to do. It is a school project, but you should be clear about it so you won't confuse yourself and those that are depending on you.
2. Another thing you should do is to do research es about how an animal cell looks like. You should be specific about this because a plant cell also consists of certain similar organelles as an animal cell. Know the total number of organelles that are present in a typical animal cell, know their names, and how they are usually structured inside the cell. The common organelles inside a typical animal cell are the nucleus, lysosomes, centrosomes, cytoplasm, mitochondria, ribosomes, endoplasmic reticulum, etc.
3. You can take your biology textbook or visit the internet to learn how to draw the structure of a typical animal cell.
4. Get materials that will help you achieve the right structure as you assemble your model.
