Planetary motions

In this activity, we will demonstrate and model the solar system motions with our selves as objects. In this activity, we will try to find what is the directions of motion and rotation of the the moon and inner planets. How can we “shift” our perspective of the solar system between a stationary observer and an observer standing on a rotating Earth?

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?

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.

Micrometeorites on your rooftop

Every day, several tons of cosmic dust falls down onto our planet, and roof tops have proven to be the ideal place to look for micrometeorites, even in busy city environments. You can join the hunt, and if you’re lucky you might find your own micrometeorite on the roof of your school or a local warehouse.
