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.

    • Process of inventing worksheet due Monday

  • Bell ringers due at final
