Think Like a Scientist: Make a Model of the Sun and the Earth

You will need: a globe of planet Earth, a flashlight

Marcus and Arun have a globe of planet Earth.

What to do:

The torch shows how light from the Sun gives daylight.

Safety First:

Be careful not to shine the flashlight in someone’s eyes.
It could hurt their eyes.
