Zoology Science Fair Project

Diffusion and Osmosis in Animal Cells

Diffusion and Osmosis in Animal Cells | Science Fair Projects | STEM Projects
Are you curious about how different solutions affect an animal cell? Join us in this experiment to observe if substances pass through the cell membrane!


The hypothesis is that different solutions will affect an animal cell and substances will pass through the cell membrane.

Method & Materials

You will make different solutions to test three egg cells, pour the solutions over the eggs in jars, and observe changes over 1 to 2 days.
You will need 3 raw eggs, 3 clean jars with lids, 3 liquids for testing, measuring tape, kitchen scale (optional), and paper towels.


The experiment showed that different solutions do affect an animal cell and substances do pass through the cell membrane. The most interesting observation was that the eggs changed size when placed in the different solutions.

Why do this project?

This science project is interesting and unique because it allows students to observe the effects of different solutions on an animal cell and to see if substances pass through the cell membrane.

Also Consider

Experiment variations to consider include testing different concentrations of sugar solutions and testing different types of solutions.
