Osmosis in Eggs

Osmosis in Eggs | Science Fair Projects | STEM Projects
Ever wanted to know what happens when you put an egg in salt water? In this science project, you'll find out by measuring the weight of the eggs before and after being immersed in the solution.


The hypothesis is that water will pass through the shell of an egg, to the side that has a solution of higher concentration.

Method & Materials

You will label 3 eggs and 3 beakers, fill each beaker with 400ml of water, and add different amounts of salt to each beaker. You will then place the eggs in the beakers and leave them for 24 hours.
You will need 3 eggs, 1200ml of distilled water, 300gram of salt, 1 measuring cylinder, 3 beakers, 1 weighing machine, 1 spatula, 3 pieces of styrofoam cut to beaker size, and 1 black permanent marker pen.


The results showed that the weight of the egg placed in distilled water had increased, while the eggs placed in salt water had decreased in weight. This proved that the hypothesis was correct - water will pass through the shell of an egg to the side that has a solution of higher concentration.

Why do this project?

This science project is interesting because it demonstrates the process of osmosis, which is an important process for living organisms. It also has practical applications, such as water purification and water recycling.

Also Consider

Variations of this science project could include using different soluble materials like sugar or syrup, or repeating the experiment at different temperatures to see if temperature has any effect on the osmosis process.
