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

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.

Using Stellarium

Stellarium is a tool where you can study the skies just like the astronomers. You can repeat the observations of Jupiters moons done by Galileo Galilei four hundred years ago, or you find stunning real-life pictures of your favourite deep sky object.

We have collected some simple instructions to get you started with Stellarium. Download these files, and start learning and having fun!


Moon Flip-book

In this exercise we will observe the phases of the Moon over time or using Stellarium. Afterwards we draw each phase in to a series of cards, which we use to make our very own moon-book, which you can flip through to remind and entertain you.

Age Range: all ages, younger children will need help with scissors.
Prep. Time: 5 minutes
Activity Time: 20 minutes
Cost per activity: Low
Materials: Scissors, Stapler, Pencil / colours, Thicker paper


Identifying Meteorites

Did you find a curious looking rock? With the help of these instructions you can investigate if it could be a meteorite.

This presentation will lead you through the common features of micrometeorites, including magnetism, weight, surface features and evidence of fusion crust, chondrules, metal flakes, patina and rust.

Interesting findings are worth submitting to an expert for analysis. With scientific methods any meteorites can be reliably identified and categorised. The presentation also guides you to where you might find such advice!

Classroom Constellations

An image of the orion constellation

This lesson begins with a presentation on Constellations. Students are introduced to the Northern sky and discus topics such as: What is a constellation? What are the names of some constellations? Why are some stars brighter than others? and How do we label stars?

The activity of this lesson involves students choosing a constellation and using metal food foil and a mobile phone (or other torch) to project it onto the ceiling of the classroom.

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.
