Multiple-choice test questions can be confusing. Here's a toolbox of tricks and strategies to help your teen become a multiple-choice master.

Research currently available fuel sources, and fuel manufacturing and processing techniques. Propose an alternative fuel source.

This experiment will explore if a randomly iterated algorithm will result in a pattern.

Check out this cool science project idea to explore how temperature creates annual rhythms that govern plant growth.
