Earth science projects are a cool way for kids to find out about the earth around them and learn more about science. There are a lot of “earth sciences” , so your kid has lots to choose from! Here are two of our favorites:

Does salt affect the boiling point of water? Measure the temperature at which distilled water boils. Add different amounts of salt, and measure the differences. This is an easy earth science experiment that can be done in under 24 hours. Find out how to get step by step instructions on this earth science project below.

5. Which bathroom tissue is best for the environment? Get samples of different brands of tissue and weigh them. Then soak them in water so they break down. After 24 hours, flush the samples through a funnel, then weigh the rest. We called this project at “A Straight Flush“.

Your free science project guide has information on how to get detailed instructions for both of these earth science projects . Get your free parent’s guide to science projects – are at http://www.24hourscienceprojects.com.

Examples of science fair projects will help you get started with this year’s science fair. Here are some ideas to help you as you prepare. There are five types of science projects, and we’ve included an 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 example 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!
