Here's an easy way to measure the speed of light in your classroom without wrecking your budget

Investigating the Center of Gravity Classroom Kit Sensors & Data Collection The Conductivity Tester is aThis easy to use classroom kit lets students explore how gravity acts on an object and teaches them a simple method of determining an object's center of gravity. The set investigates five different amoeba like shapes including a teacher's larger "challenge shape" with its mass surrounding a point in mid air.
