Insulators
Which state of matter has a definite volume but no definite shape, taking the shape of the container it is poured into?
Liquid
Sarah mixes sand and small pebbles together in a bucket. Which best describes this combination?
It is a mixture because the individual substances keep their own physical properties and can be easily seen.
You drop a small wooden block and a glass marble into a beaker of water. The wood floats, and the marble sinks. What does this tell you about the density of the wood compared to water?
The wood is less dense than the water.
What is volume?
The amount of space an object or liquid takes up.
Define the word magnetism.
How do the particles in a solid compare to the particles in a gas?
Solid particles are tightly packed and vibrate in place, while gas particles move freely and spread far apart.
You accidentally spill a box of iron paper clips into a bowl of dry sand. Which physical property can you use to easily separate the paper clips from the sand?
Magnetism

Define melting point and when it occurs?
The melting point is when something heats up and the particles move fast turning into a liquid.
Give me one example of a mixture, solution, and solubility.
Listen to examples.
Which one of these is less dense and why?
A metal spoon or wooden spoon.
A wooden spoon is less dense because it floats on top of the water and does not sink.
Define mass.
Mass is the amount of matter or "stuff" that makes up an object.
