Students apply their knowledge of friction, drag, mass and gravity as they design, build, and test mini-bobsleds.

Sooner or later we all fall down. Mountain biking has its hazards and crashing and falling are a part of riding in the mountains. So it's best to learn how to take a fall and minimize the injuries. So the best way to fall is to do a tuck...

Students compare and contrast where friction occurs in robots and bicycles. In this science activity, students label the diagram of bicycle and robots. They investigate how friction affects their different parts.

Students view a video on friction and examine how friction and gravity affect some sports.  In this investigative instructional activity students write a paragraph and draw a picture that illustrates how friction and gravity affect...

A real-life example of a ball rolling down a ramp to see whether mechanical energy really is conserved when objects roll down hills. Students analyze video clips of children rolling down a driveway on roller blades and various bikes and...
