What happens when you expose fruit flies to low temperatures? Like many insects, they go into a chill coma - a sleepy state. Analysing the phenomena of coma recovery could help teach the concepts of rapid evolution, and the impact of climate change on it. How? A team of scientists and educators created a wholesome teaching module of fruit fly experiments using the phenomena of "chill coma recovery".
Starting with a probable questions, followed by hypothesis-building, can lead to a good experiment design where students participate and discuss their own ideas and approaches.
