ACTIVITIES:
The Science of Bikes
Energy in all forms cannot be created or destroyed, energy can only change from one form to another. Learn how bikes use energy to move, and how bike parts work together to accomplish this movement. https://files.nc.gov/ncparks/nc-culture-falls-lake-bike-science-discover-more.pdf
On Your Bikes!
In this activity, students measure speed and drag for a person on a bike to determine the effects of aerodynamic drag and rolling resistance on a cyclist’s maximum speed. https://www.sciencelearn.org.nz/resources/1352-on-your-bikes
Bicycle Jeopardy
Your choices behind the handlebars make a difference! Here’s everything you need to play “Bicycle Jeopardy.” Contestants select the category, answer questions, and tally points.https://www.bike.nyc/wp-content/uploads/2020/04/2020-Bike-Jeopardy-Middle-and-High-School-FOR-TEACHERS.pdf
Bicycle Centrifuge
A common use for a centrifuge is to separate blood into red blood cells (which gather at the bottom) and white blood cells and plasma at the top. This hands-on activity demonstrates how to make your own centrifuge using a bike. https://www.science-sparks.com/bicycle-centrifuge/
Newton’s Second Law
Provide two identical bicycles that each have a basket. Keep one basket empty. Add bricks (mass) to the other basket. Invite students to ride each bicycle and note the difference in force needed to propel the bikes. https://blog.indypl.org/kids/newtons-second-law-of-motion/
