Explain that when an explorer or an expedition discovers a new place, it is tradition to take a photo there. Ask the pupils to draw a picture of the alien on the alien sighting pro forma, and while they are doing this circulate and photograph the pupils pretending to be aliens.
If you have time and resources you can add face paint/costumes/props etc
