Gearing Up for Speed Workshop
What gear combination do you use to make your car go fast on level ground? Does that same combination work going up hill? Do belts and pulleys work better than gears? Students use gears, belts, and pulleys to build a transmission system for their motor driven cars. They then test their cars on up hill and down hill slopes, experimenting with different gear combinations, to get the fastest, most efficient car possible for the various conditions. They learn how different gear combinations are used for different purposes. Using grade appropriate math skills, the students use the data collected to determine why some gear combinations work better than others.
