Experiments in Science: Time Lapse Video
Richard Needham, from the National STEM Learning Centre and Network, demonstrates how to use time lapse video to speed up action that would otherwise be either too slow to notice within a normal school science lesson, or to provide opportunities to explore gradual changes outside a classroom.
Examples of biology experiments which could be enhanced by this technique include plant growth responses, reactions to light, the rotting process, and germination. Time lapse video can also be used in chemistry to demonstrate crystal growth or displacement reactions or, in astronomy, to show the motion of planets.
