STEM – Biology Class

The Biology class is learning about animal and plant responses. Students did a series of practical experiments to observe the responses of worms – specifically taxis (directional response) and kinesis (non-directional response) – by exposing the worm to different stimuli. For example, they found that worms moved towards the damp towel (positive hydro taxis) but wriggled around when they dropped a drop of water on the ‘head’ end of the worms (hydro kinesis).
