Isaac Newton was a famous scientist who loved figuring out how the world works! One day, he was sitting under an apple tree when an apple fell right on his head. That falling apple helped him discover gravity, which is the invisible force that keeps us on the ground. He also learned that gravity is what keeps the moon spinning around our Earth!
Isaac didn’t just study gravity, he also loved to learn about light and colors! He used a special piece of glass called a prism to show that white light is actually made of a beautiful rainbow. He wrote down all his smart ideas in a big book that scientists still read today. His amazing discoveries help us understand how everything moves!
