Science Fair Project Idea
Watching a spacecraft launch is an amazing experience. It is thrilling to see it lift off and escape Earth's gravity. Did you know that it takes a chemical reaction to get a spacecraft into space? Every time you see a one blast off, you are watching chemistry at work. In this chemistry science fair project, you will also get to blast an object into the air. You will not be using the same fuel that NASA uses for the rockets that launch their spacecrafts; instead, you will use two simple… Read more

Did you know that soils can be alkaline, neutral, or acidic? Most plants grow best in soil near neutral pH, but some plants prefer slightly acidic and others slightly alkaline soil. What is the pH of the soil in your garden? What happens to the pH of water that comes in contact with soil? In this science project you will get to find out. Read more

Science Fair Project Idea
Objects that glow in the dark hold a special place in the imagination of both children and adults. The lights go out at night, but these odd things refuse to disappear. Where does the light come from? Do they work in any climate? In this science fair project, you will make a very simple electronic device to measure the light given off by luminescent materials. The device will be used to study how temperature affects luminescence. Read more

Science Fair Project Idea
The rates of some chemical reactions can actually be increased by adding light. Light sometimes interacts with one or more of the chemicals and provides an "energy boost" that dramatically speeds up a normally slow reaction. In this photochemistry science project, you will experiment with the effect of light on a chemical reaction. The reaction converts iodine, which forms a dark-orange solution, to iodide, which is colorless! Read more

Science Fair Project Idea
The ingredients in Alka-Seltzer® tablets undergo a chemical reaction that produces carbon dioxide gas as soon as the tablets hit water. Do you think you can cause the tablets to produce gas faster by breaking them into smaller pieces before dropping them in water? Find out for yourself with this project. Read more

Do you hate shots? Do you complain about paper cuts? Imagine if you had to give yourself shots a couple of times a day, as well as prick your finger, on purpose, even more frequently. Of course, if you have diabetes you do not have to imagine this; it is your reality. People who have diabetes usually need to keep close track of how much sugar is in their blood (called their blood glucose levels) by testing a drop of blood from a finger prick. If there is too much sugar in their blood, some… Read more
