Recyling aluminum foil.

Recyling aluminum foil.

There are five types of science projects, and we’ve included a fast and easy example of each.

1. What condition is most favorable for decomposing an apple? Place three identical apples in zip lock bags. Add soil to one, water to another, and let the third simply be exposed to air. Watch the decomposition over three weeks. This project is an observation or demonstration, as the results cannot be measured.

2. What products in the home are made from recycled material? Gather items made from reclaimed materials and arrange them into an attractive display. This is a collection.

3. What kinds of birds live in Hawaii? Use books and the internet to research the answer to this question. Type up your findings and present them in a paper. This is a research project or a science report.

4. What temperature water is best for activating yeast? Fill three small bottles with water, one with hot, one warm and one cold. Add sugar and yeast to each bottle, and quickly place a balloon over the bottle mouth. Measure the tallest balloon to see which temperature activated the yeast. This is an experiment, or an investigative project. It follows the scientific method.

5. Make a model of DNA. Use craft beads and chenille wire to make a model of Deoxyribonucleic acid (DNA), the building block of life! This is a model.

You can use any of these fast and easy science fair projects, as long as they conform to the guidelines of your fair. But don’t stop at these. Let them give you ideas of your own!
