Elementary Science Fair Projects
I want to give you three ideas here for elementary science fair projects that can be easily done at home. And best of all you probably won’t have to buy any supplies for these projects since you likely will have them at your house already.
These project ideas are about the process of Diffusion. Don’t be afraid of that strange sounding name because the process of diffusion is really very easy to understand. It simply means that the atoms or molecules (The stuff that makes up everything) of a substance are constantly moving and in certain situations can mix in or diffuse with those around them.
1) The first idea for your elementary science fair project is to design an experiment that would show if things diffuse differently depending on how hot or cold they are. Will diffusion take place faster if the temperatures of the substances are higher? Will it go faster if the temperatures are lower?
2) The second idea is to test if molecules evaporating from a liquid will diffuse into the surrounding air and be dispersed or spread out through a small room in a period of time. Its easy to think of an experiment to test this idea.
3) The third idea is to demonstrate a type of diffusion called Osmosis that occurs in living cells. Osmosis is the movement of liquids and dissolved substances into and out of cells through a cell wall or membrane. We can easily show this movement from an area of higher concentration to one of lower concentration using plant cells. Osmosis is a very important principle in biology and a simple project can show you how it happens.
Do some research and learn about the scientific principle of diffusion and how it works. This will make it much easier to form an hypothesis (an idea you would like to prove) for a project and to create a simple experiment to test it. Also read some about the process of osmosis in plant cells and understand why and how the movement of substances across cell membranes occurs.
