Class 8th: Videos

​

When an object is viewed through two mirrors, light bounces between them like ping pong, leading to formation of multiple images. You'd observe that lesser the angle between the mirrors, more the number of images.

Build a circuit on a board using pencil cells/batteries, a switch, LED bulb and connecting them using wires.

Heat moves away from the point where the object is being heated, and spreads to the whole of the container. The coin which is closest to the candle will fall first, followed by the rest.

Sunlight, which comprises of seven basic colors, splits into them when it passes through a prism.

Build a Kaleidoscope with the mirror provided with the Windchimes Kit

Take the solution of Copper sulphate in a container, and dip the copper electrode and the object to be plated. Upon passing current, a layer of copper will be deposited.

Make a slightly more complex circuit using two LEDs and/or buzzer/speaker

Testing which solids can be conducting, which can not. Prepare the circuit as done before, and touch the electrodes to different solids one by one. If the solid is conducting, the bulb will glow.
