Learning intention: I will learn what the term matter means, how to classify different types of matter and how to demonstrate changing states of matter.
Notes from the 2 videos:
- Matter is anything that has weight, and takes up space
- Matter comes in different forms, or ‘States’
- Solids stay in one place and can be held.
- Solids keep their shape. They do not flow like liquids.
- Solids always take up the same amount of space. They do not spread out like gases.
- Solids can be cut or shaped.
- Even though they can be poured, sugar, salt and flour are all solids. Each particle of salt, for example, keeps the same shape and volume.
- Heating some solids can turn them into liquids.
- Liquids change their shape depending on the container they are in.
- Even when liquids change their shape, they always take up the same amount of space. Their volume stays the same.
- Gases are often invisible.
Definitions of solid liquid and gas:
Solid~a solid is a substance that has partials that are packed tightly together. Solids always take up the same amount of space and always stay the same shape.
Liquid~a liquid is a fluid that molds to the shape of the container its in. The partials in the liquid are close together, but they can slid past each other and flow easily.
Gas~gas partials are not close to get her like the other matters but move freely around. If gas gets stuck in a container it fills the shape and volume of the container.
6 ways to change state of matter:
Freezing: liquid to solid.
Melting: solid to liquid.
Condensation: gas to liquid.
Vaporization: liquid to gas.
Sublimation: solid to gas.
Deposition: gas to solid.
