This project is a computer program that shows how planets move around stars. It uses math to demonstrate Keplers Laws of Planetary Motion. Here is what this project shows us about science: 1. KEPLER'S 1ST LAW (Law of Ellipses): The planets do not go around the star in circles. If you look closely you can see that the lines they make are actually ovals and the star is a little bit off to one side at one of the focus points. 2. KEPLER'S 2ND LAW (Law of Equal Areas): The star pulls harder on the planets when they are close to it. You can see that the planets move faster when they are near the star and they slow down when they are away from the star. 3. KEPLER'S 3RD LAW (Law of Harmonies): The planet that is away from the star takes longer to go around it. This is because Planet 2 which is like Earth and is light red started out away from the star so it moves slower and takes longer to complete one loop around the star than the planet that is closer, to the star. This project was made using Scratch code blocks, special variables and a tool called the Pen extension.
