This apparatus demonstrates the behavior of a bimetallic strip when heat is applied. This unit consists of a bimetallic strip on a 130mm x 80mm x 30mm base. A 12V halogen bulb is mounted right below a metallic strip. The bimetallic strip is heated by the glow of the bulb, which then bends, the circuit breaks and the bulb goes off. Once the bulb cools, the circuit becomes complete, the bulb glows and the sequence is repeated. Sockets are safety sockets.

Projectile launcher is used to study kinematic equations, and conversion between gravitational potential and kinetic energy. Students participate in an interactive experiment for measuring the muzzle velocity of the launcher to identify varying launch angles in order to quantify the initial kinetic energy of the projectile (ball). Using their velocity calculations, students then make predictions about where the ball will land.
