The Sun is a constant presence in our life on Earth. It gives us the heat and light we need to survive. But it is not a stable place. The Sun is a ball of hot plasma which is constantly changing.

You have probably seen the Moon in the sky, but have you ever studied it in detail?

Asteroids are small, rocky objects that orbit the Sun. Most are located between the orbits of Mars and Jupiter. This area of our Solar System is known as the Asteroid Belt.

You have likely heard about the Universe expanding. Or that redshift can tell us about the movements of galaxies. Both are difficult ideas to imagine and understand.

Is gravity the same everywhere? Experiment with how the ball reacts in each of the Solar System locations by dropping or throwing the ball. How similar or different is each location to Earth?
