I really like this video – starts with an observation, and a question about it. It took engineering and ingenuity to find the answer, but more questions arose along the way. If you like science experiments, you will love this 24 minute video! www.youtube.com/watc… I decided to send it round as it emphasises the value of experiment and observation to develop knowledge and understanding, where knowledge was incorrectly assumed to exist.
