How Fast is 100 Beats a Second

WHY?

Insects are able to propel themselves through the air for a sustained period of time by flapping their wings. The repetition in which they flap them is difficult to see with the naked eye. The rapid movement in beats per second can be seen with a time-lapsed camera. Experiencing beats per second can give a student an idea of the ability of an insect in flight. The next time you see a housefly in your kitchen try to count how many times it flaps its wing in a second. It is impossible to do!

ASSESSMENT: Can the student communicate what they observed?
