England Key Stage 3

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?

Ever wondered how heavy or light you would feel on another planet in our Solar System?

The level of the sea rises and falls about 2 times each day. We call these changes tides. But what causes them?

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?

Every year, the Earth completes one orbit of the Sun and every year, you have a birthday!
