Matter
Did you know everything you can see touch or feel has matter. Even things you can’t see has matter. Matter has three states solid liquid and gas.
Solids are hard. It is things like tables, chairs, beds, books. Solids are normally hard. In a solid there are these tiny little things called molecules. The molecules in a solid are all tightly packed together so they have no space to run around.
Liquids are fluid. Liquids are thins like water, drinks, rain, tomato, sauce. The molecules in a liquid have a little space to jog around. So this means a liquids floppy.
Gas’s are soft. You can only feel a gas’s temperature. Gas is like steam smoke or clouds. Molecules in gas can run around quickly. This means you can’t feel a gas because the atoms run straight through you’r hands.
Did you know one state of matter can change to another state of matter? For example if you leave a block of ice on a table after maybe a few hours there it will have melted and became a liquid. Thats because while it was on the table in the open heat energy was added to the block of ice. If you wanted to change the water into a gas you’d have to add more energy. Like when you put water in a kettle. The matter in the water are getting more heat energy thats why steam comes out of the top of the kettle.
You can also take away energy from matter. So like if you had water which is a liquid, you could freeze the water which takes away heat energy and adds cold energy. Which turns the water to ice.
In matter there are tinier things than molecules called atoms. Three atoms equal one molecules. Atoms are kind of the same as molecules. Just like molecules when something is a gas the atoms move around quickly. And when something is a liquid the atoms jog around inside. And when something is a solid the atoms in a solid are slow and have no space to run around.
Solids are hard. Liquids are fluid. Gas’s are soft. States of matter can change.
WALT: inform
DESCRIPTION: Write an explanation about something you have learned about energy.
Feedback: Cool that really is cool. Kyan
I think I did very well on this because I was able to put all of my ideas on
| state the main point in the first part of a each new paragraph |
|
| You have started with a point to clue the reader into each paragraph. These are clear. |
| include evidence (facts, experiments etc) to support my main point |
|
| You have included great examples (evidence) that the reader can relate to. Well done. |
| explain the evidence and how it proves my main point |
|
| You have persevered to try to explain how/why your example proves your point - this is really tricky, well done. |
| Practise writing a linking sentence to my next paragraph |
|
| I can see that you have tried to link between ideas. Linking between paragraphs is a lot harder. |
| infuse style: topic-specifc vocab, second/third person, present tense, transition words |
|
| Great style. Don’t forget to use lots of transition words. |
