Today's topic was about a simple machine called a Pulley. A pulley is a simple machine consisting of a wheel with a grooved rim in which a pulled rope or chain can run to change the direction of the pull and thereby lift a load.
We watched a video of a pulley and then we discussed more on the topic.
Next, we created a pulley with blocks and poles. We used a string and a bucket to lift the loads. Everyone had a chance to lift their loads. We had so much fun as we could see some loads are heavier and some are lighter to lift.
