S2 Task cards

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.
Heating a liquid can turn it into a gas
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.

States of matter that water can be in:

Clouds(gas), snow(solid),and rain(liquid) are all made of up of some form of water. A cloud is comprised of tiny water droplets and/or ice crystals, a snowflake is an aggregate of many ice crystals, and rain is just liquid water.

Check list:
  1. Evidence of the notes you took while watching the two videos
  2. The definitions, in your own words, of solid liquid and gas
  3. Diagram showing water changing states
