A space station is like a home in space, where astronauts live and carry out experiments. Astronauts and things in space float around because of weightlessness. Astronauts eat freeze-dried foods and drink though straws when they are in space. The atmosphere surrounds the Earth. It provides oxygen to help us stay alive and protects us from the heat of the Sun and the extreme cold at night.
Astronauts travel into space and they use the Earth's gravity to orbit around it.
When people go into space they need to take their own supply of oxygen and wear suits to protect them from the lack of oxygen, extreme temperature changes and micro-gravity. Before viewing the program Make a list of different kinds of transport. Group them into those that move on the ground, on water, in the air. Discuss what the children already know about space travel.
