The spin is in – the shape of galaxies

The spin is in – the shape of galaxies
Publication Date: July, 2014
Type of Resource: Practical activity/investigation

This online resource details an activity that allows students to model the different shapes of galaxies with water and powdered milk.

Spinning the water container as the powdered milk is sprinkled in creates shapes that replicate the motion of galaxies. Varying the speed of rotation creates variations which students can sketch and compare to the shapes of real galaxies.
