Bell Ringer: for a machine that launches a projectile, what factors can you manipulate in order to change its range?
In groups of 3-4, design and build a catapult, trebuchet, sling shot, or other ping pong ball launcher which can be adjusted to launch to different distanaces.
Calibrate your launcher so you can hit a target placed anywhere from 1 to 3 meters away.
To judge effectiveness, we'll fire on a model castle with our launchers at the end of the period.
