EGGS SIMULATING HUMAN CELLS - OSMOSIS

Science in 3rd ESO

Students in 3rd ESO were enquiring about Human cells. They posted questions in a class discussion and they realized they needed to see how human cells are and what they look like and specially how they work inside the human body.

Students dissolved eggshell to obtain a thin membrane that resembles the plasma membrane of human cells. After that, they immersed the eggs into different concentrations of salted water and observed how water enters or leaves the egg with the process of osmosis. This is exactly what would happen with human cells.

Ósmosis Experiments

It was a great experiment to see how the human cells work in our bodies.
