Year 4 SCIENCE | 4/5M completed scientific investigations of a mystery non-Newtonian substance, which all students thought was amazing. 

Newtonian fluid | fluids which DO NOT change their thickness (viscosity) when force is applied to it. I.e. water and oil always flow the same way, no matter how hard or soft you push it.

Non-Newtonian fluid | a fluid which does not follow Newton’s law of viscosity. It’s thickness (viscosity) changes when force is applied to it.
