100

This thing is anything that has a mass and volume (takes up space).

What is matter?

100

This substance has different particles. 

what is a mixture?

100

This substance has identical particles. 

What is a Pure Substance?

100

How much a liquid can flow

What is viscosity? 

100

This is an example of a fluid with low viscosity 

What is water?

Other example: tea or juice 

200

This is a model made up of several postulates (assumptions).

What is the Particle Matter of Theory? 

200

This is also known as a mechanical mixture.

What is a heterogenous mixture?

200

There is another term for homogenous mixtures.

What is a solution?

200

how long it takes for a fluid to reach from one point to another

What is flow rate? 

200

This is usually measured in grams (g) or kilograms (kg). 

What is mass? 

300

These things are always in constant motion.

What are particles? 

300

This makes up the largest part of of a solution.

What is a solvent?

300

This dissolves into a solvent and makes up a smaller portion of a solution.

What is a solute?

300

This is an example of a fluid with high viscosity. 

What is honey? 

Other examples: shampoo or oil. 

300

This looks at how much mass is in a particular volume. 

What is density? 

400

Grade 8's: This is the most compressible state of matter. 

What is gas? 

400

This solution contains less amount of solute that can be dissolved. 

What is unsaturated solution?

400

This solution has more solute than would typically dissolve in a standard solution. 

What is supersaturated solution?

400

This determines whether an object can float or sink in a given fluid.

What is buoyancy?

400

This is concerned with how much space a particular substance occupies. 

What is volume? 

500

Particles of matter are drawn to one another via intermolecular forces of attraction, which vary in strength.

What are spaces between particles? 

500

This is a technique for sorting solids based on their sizes by shaking materials as they pass through a mesh or screen.

What is sifting? 

500

This is an example of a liquid-liquid solution. 

What is a hand sanitizer? (70% alcohol and 30% water) 

500

A French philosopher and physicist, was curious to learn what happens to a fluid when there are external forces applied to it.
