Science Fair Idea Science Fair Idea Hello! My name is Symone and I really love doing the science fair each year. Recently, while trying to come up with an idea, I thought about conducting an experiment where I test to see if getting an extra 20 minutes or so of sleep in the morning actually helps the body be more energized throughout the day. The way I would conduct this experiment would be through creating a simple machine that can track the brainwaves of a person sleeping. My only issue is… Read more

Experiment for choosing a bike gear for uphill

Ask an Expert Topic Forum: Grades 6-8: Physical Science

Experiment for choosing a bike gear for uphill Experiment for choosing a bike gear for uphill My homeschooled 7th-grade son is doing a science fair project on choosing the best gear to go uphill. After our research, he understands how gear ratio works, how to determine gear ratio, why we need a low gear ratio for uphill and how more force/torque is created on the gear/wheel; thus he is able to make a very good educated hypothesis. However, we are having a hard time determining a way to use an… Read more
