==

A fluid is matter that flows.
===Flow means that a matter can move from one container to another taking the shape of the container.===

No air space in fluid.
Examples.

**Viscosity is the measure of how fast a fluid can flow. How thick or thin a fluid is.**

 * High Viscosity= slow flow= High density eg maple syrup
 * Low Viscosity = Faster flow= Lower density. eg water

=__E. Scientific Process.__= You will be information to create a lab. Make sure you know the proper way to write a lab. The question is who has a better memory, Grade 7 or grade 8?

The experiment will be playing the Game Simon. You will need to write a lab with this question during the exam. You will be given the average level for each grade.
