Memory


 Different types of memory from 1K chips to 32Gb RAM Modules and much in between. The students learnt how they work and everything about RAM and ROM.

Order of Reactivity


Order of reactivity of metals - this was a tough one for the students because they had to devise their own experiments; with a lot of help, they achieved a result. Next time they have to compare metals and their sulfates prediction and proof.

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.

Cheek cells +


 What are all those little black things with my cheek cells asked a student, looking down the microscope at his freshly prepared cheek cell slide. These are bacteria. He went and brushed his teeth immediately and prepared a new slide.

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.

Doppler Rocket

Demonstrating the Doppler effect with the @pascoscientific Doppler Rocket: As the rocket moves away, students can hear the pitch drop (red s...
