Astronomers use telescopes to see objects far away in space. Did you know that we can only see an object if it emits light or if it reflects light? 

Did you know that what you weigh depends on the strength of gravity? And did you know that the strength on gravity on other planets is not the same as on Earth?

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! And during a year, the Earth rotates 365 times on its axis and we experience 365 sun rises and sun sets.
