Colour the universe

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

Nebula in a Bottle

In this activity, the students will gain knowledge of the observable universe and the spectacular sights to be discovered when observing it. They get to unleash their creativity with creating nebulae and along with this learn that the Universe can come in a variety of colors, structures and shapes. 


Make your own Orrery

Orrery’s are fantastic tools to demonstrate the planetary motions in our Solar System, but rare since they often require an advanced (accurate) clock work to work. It is however straight forward to make one for your self with paper and scissors. The children can colour their own orrery and play with it to explore several interesting phenomena in our Solar System.

Download the pdf and print it, one per child, and follow the instructions printed on the sheet. You will need colours, scissors, split pins (split clips) and a laminator (optional). If you do not have a laminator machine, it is advisable to print the file below on the thickest paper you have available.

How to identify a meteorite

Did you find a curious looking rock? With the help of these instructions you can investigate if it could be a meteorite (or a meteowrong!). You can also go outdoors and pick any rock for investigation. Or how about hunting micrometeorites?

Classification of the Universe

In this activity, the students will learn different ways of roughly separating the features of observable structures in the universe and will gain the tools needed for identifying what kinds of objects they can observe through telescopes when visiting the observatory. 


The sky above us

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).
