Steady hand game

Currently doing electricity with Sec 3 NT and here’s throwback of a bonus activity I did with them last year for the chapter on Electricity. Each pair received a kit of battery, chopstick, straw, lightbulb, wire and index card to make their own steady hand game.

The video shows my first prototype 👏

It was not that difficult. They managed to get it done within 1hr lesson.

They designed their own loop and had fun challenging each other. A player is out if the bulb lights up.

Sources of light

To introduce to students that light is a form of energy, I usually highlight some examples of energy changes to light energy.

Here are some stuff I use for to demonstrate the energy conversion…
