Ideas For A Science Fair Project


Coming up with ideas for a science fair project is the easiest part of the whole process, just think of a topic that interests you and then think of something that you’ve always wondered about. Then, take that topic and there you have it; your question! After this, it’s just a matter of doing some tests to answer your question.

I recommend these printable science project plans for K-12 for hundreds of great project blueprints and this step-by-step guide for doing an award winning science fair project. Also be sure to check out these fun science kits as a fast, simple way to get started on your science experiment.

Materials Needed:

  • Two new pennies
  • Two glasses or bowls
  • Orange juice
  • Soda


Rusting Pennies For Science
Experiment: What will make a penny rust faster, orange juice or soda?
Category: Chemistry
Ages: Elementary School, Middle School


One idea for a science fair project is to see which liquid will make pennies rust faster, orange juice or soda. This is a great project for a beginner as there is not too much work involved, and it requires few supplies. First, you need to find two new, clean pennies, some orange juice and soda, and obtain two bowls or glasses to put the liquid and pennies in. Place a penny in each bowl or glass and fill one part way with orange juice and the other part way with soda. Wait about one week and then check the pennies. Do either one of them have any rust on them? They may not yet, and if they do not you will have to leave them for another week and check them again. Be sure to record your results! This project is a good one for people who have some time to complete their project. If you have a limited amount of time, then you might want to think of some other ideas for a science fair project that are a little less time consuming.
