Easy Elementary Science Projects – Air In Soil
Easy Elementary Science Projects – Air In Soil
This is one of our easy elementary science fair projects where it is best to a camera to record your findings as it is all visual. There will be nothing for you to measure or evaluate only what you see visually.
The idea of this easy elementary science project is to see if there are different amounts of air in different kinds of soil.
What you need for this easy elementary science project:
- A camera
- 3 Small clear jars
- Water
- Samples of three different kinds of soil, e.g. clay, good with lots of organic matter in it and very sandy soil
How to do this easy elementary science projects:
- Half fill the jars with your soil samples
- Fill the rest of the jars with water until almost to the top
- Make your observations as air bubbles rises to the top of the jars.
- Take photos every few seconds to record your findings
- Why are we looking at the bubbles rising in the water?
- What does it prove?
- In which kind of soil did the most bubbles rise to the top?
- What does this prove?
Well, the more bubbles rising through the water, the more air was trapped in the soil sample. Tightly packed soil has less air trapped in it than soil with a lot of humus or other organic matter. Almost all kinds of plants tend to grow better in this kind of soil.
I think this experiment is one of our easy elementary science fair projects that are for the budding “gardeners” amongst our young! Enjoy!
