Tension Protractor


 When you need the @pascoscientific tension protractor, nothing is quite like it. The Zipline practical becomes a breeze when you know the force and direction, which are otherwise difficult to calculate or measure.

Sicherman Dice


 These dice have the numbers 1-2-2-3-3-4 and 1-3-4-5-6-8, but give the same sums with the same probabilities as two normal 1-to-6 dice. The only difference is the odd of rolling a double which as usually 6/36 are 4/36 for the Sicherman dice.

Seebeck effect

Thermoelectric generation using a Peltier Module to utilize the Seebeck effect to generate voltage. When heat is applied to one of the two semiconductors, heated electrons flow toward the cooler semiconductor. If the pair is connected through an electrical circuit, direct current flows through that circuit.

Wind up Car Racing


 Physics is fun. The students played with wind-up racing cars to investigate energy changes. They came up with all the energy losses on their own, demonstrating the benefits of practical learning over theoretical learning.

Shapes of Molecules

The shape of the molecule affects the shape of the crystal. Modelling using dice shows how different shapes can and can't fit together and gives rise to the crystal shapes we observe.
