Chemical change Science Projects - Cool Chemistry That a learner Can Do

,

Chemistry science projects involving a chemical convert are often chosen by middle and high school students. Many kids like to do an experiment with a dramatic chemical change. When searching for a project, it can be difficult to find an experiment with chemicals that are easy to find, and easy to work with.

One beloved project inspiring chemicals is an experiment determining which fruit or fruit juice has the most vitamin C. A uncomplicated indicator is made with cornstarch and iodine. Students (and parents) enjoy watching the chemical reaction that occurs along with titration, which is a fancy way of saying "putting in drops". This project can be modified in any dissimilar ways, allowing your student's creativity to shine. We get letters from many students telling us that this easy science project was submitted to the fair, and was chosen as a winner.

Another great science project inspiring a chemical convert is watching what happens as yeast 'eats' sugar.  In this project, warm water and yeast are settled in a bottle with a bit of sugar. A balloon is settled over the mouth of the bottle. As the yeast consumes the sugar, carbon dioxide is released, causing the balloon to blow up. This project is so much fun to watch that our kids did it over and over until we ran out of yeast.

Both of these projects can be done as demonstrations; they offer dramatic reactions that students will be able to eye immediately. Both science projects can also be experiments. They naturally lend themselves to a question, the formation of an hypothesis, and testing. The results can in effect be graphed to form a conclusion.
