Today, Year 5 conducted an experiment to explore the relationship between mass and gravity. The children carefully measured and recorded the weights of five different balls before dropping them from the same height. To their surprise, they discovered that gravity is a constant force, meaning that all the balls fell at the same speed, regardless of their weight.

 

We then discussed the role of air resistance and how it affects falling objects. The children were fascinated to learn that if air resistance were removed—such as in a vacuum—a bowling ball and a feather would fall at exactly the same speed. This led to a great discussion about real-life examples, including astronauts on the Moon, where there is no air to slow objects down.
