Word Definitions

1) Fluid:Substances that flow (liquid & gas)

2) Particle Theory:a theory used to explain matter and heat transfer which suggests that all      mater is made up of tiny particles too small to be seen. These particles are constantly in motion because they have energy. The more energy they have the faster they move.


3 POINTS OF PARTICLE THEORY

• All matter is composed of particles.
• Particles are in constant motion.
• There are forces of attraction among particles. 

3) Flow Rate: the speed that a fluid moves in a given amount of time

4) Viscosity:the physical property of a liquid that limits its ability to flow
 ------>high viscosity = low flow rate
           low viscosity = high flow rate

Non-Newtonian

Non newtonian fluid's viscosity is changeable based on given pressure.
ex)Oobleck, Flubber,Ketchup,Silly Putty, Chilled Caramel topping ...

Photos!!
We mixed water, potato starch and some color to make a non-newtonian fluid!!
It is like solid, but if we grab it, it changes like liquid!!
