You have learned so much this quarter! Let's remember it all. Everything around you is made of matter.
Matter has properties. Properties tell us what matter is like. Some properties are color, size, shape, and texture. Some matter is hard. Some matter is soft. Some matter bends, and some breaks.
Objects are made from materials. Wood, metal, plastic, glass, and cloth are materials. We pick materials because of their properties. A window is glass because glass is clear. A blanket is cloth because cloth is soft.
Matter comes in three states: solid, liquid, and gas. Solids keep their shape. Liquids flow and take the shape of their container. Gases spread out to fill space. Heat can change matter from one state to another.
1. What do properties tell us about matter?
2. Why is a window made of glass?
3. What can change matter from one state to another?
4. Name two materials from the reading.
Write what each word means. You learned all of these this quarter!
Pick the best material for each job. Then tell why. Materials: wood, metal, plastic, glass, cloth, rubber.
| Job | Best Material | Why? |
|---|---|---|
| A window you can see through | ||
| A warm winter coat | ||
| A strong bridge | ||
| A bouncy ball | ||
| A cup that will not break if dropped |
Circle T for true or F for false.
| 1. All matter has properties. | T F |
| 2. Texture is how something feels. | T F |
| 3. Glass is a good material for a pillow. | T F |
| 4. Liquids keep their own shape. | T F |
| 5. Heat can melt a solid into a liquid. | T F |
| 6. Steam is water in its gas state. | T F |
Draw a line from each item to its state of matter.
| Item | State | |
|---|---|---|
| Steam from a kettle | Solid | |
| A wooden block | Liquid | |
| A glass of milk | Gas |
You are an inventor! Design a brand-new material for a job you choose. Maybe a super-soft shoe? A jacket that never gets wet?
