Forces and Motion

Hunting For Asteroids

Aimed at pupils aged 11-14 this workshop encourages pupils to ‘blink’ between several images, taken by the Liverpool Telescope, in a bid to find asteroids. The activity can then be extended to them using the LT Image software functionality to calculate the speed of the asteroids, or simply a discussion on what asteroids are and how we track them.

You can download the individual files needed for this activity below, or this zip file (53mb) contains them all.
