Matter Review Worksheet
| # | Answer |
|---|---|
| 1 | Matter is anything that has mass and takes up space. |
| 2 | Metal is one example. |
| 3 | Solid, liquid, and gas. |
| 4 | Solid. |
| 5 | Liquid. |
| 6 | Gas. |
| 7 | Mass is the amount of matter in an object. |
| 8 | A scale or balance. |
| 9 | Volume is the amount of space an object takes up. |
| 10 | It helps engineers know how much space a part will need. |
| 11 | Metal. |
| 12 | Density. |
| 13 | A small piece of metal. |
| 14 | Because weight affects movement, speed, and battery use. |
| 15 | They melt and become liquids. |
| 16 | They freeze and become solids. |
| 17 | So the robot parts stay strong and keep their shape. |
| 18 | Copper. |
| 19 | It carries electricity well. |
| 20 | A conductor. |
| 21 | An insulator. |
| 22 | Plastic or rubber. |
| 23 | Different materials change strength, weight, flexibility, and how well parts work. |
| 24 | To reduce weight so the robot can move faster and use less energy. |
| 25 | Understanding matter helps engineers choose the best materials for robot parts and improve how robots work. |
