Why is the Sun green in a photo taken with a UV camera? We can’t actually see UV light, so the colour of the photo was just chosen to be green!
In this assignment, you can choose any colour scale for an image of space taken to capture a specific wavelength of light. This activity is about making space images more interesting to look at! Which colours make the image look the most interesting?
Keywords: colour, light, wavelength
Find out what happened when asteroids hit Finland, Norway, Latvia, Greenland and the UK. You can also study the effects of your own asteroid impact with the Down2Earth impact calculator!

The rotation of the Earth is investigated by observing the length of a toy figure’s shadow in the course of a day.
As an extended task, you can use the Stellarium software to investigate the movements of the Sun. Alternatively, the students can make real observations of the position of the Sun in the sky in the course of a year (the analemma pattern).
