A high school assembly presentation on the search for & implications of alien life. A 10-15 minute talk on various sensible aspects concerned with the question of alien life. Use the commentary alongside the presentation/link. This assembly was very well received by all yeargroups at my school and would also work well as a starting point for a citizenship, physics or applied science lesson.

KS2, KS3, GCSE enrichment, logical thinking, prime numbers. Inspired by Sir Patrick Moore, this activity prompts pupils to think about what kind of message we would send to aliens and how we would send it. After considering various issues, pupils complete a 'paint by numbers&' activity to see what Sir Patrick Moore recommends. A second, real life, extension task based on the Arecibo Message is also included. Answers and internet links included, plus a link to the message that NASA put aboard the Voyager spacecraft (the only spacecraft to leave our solar system).
