Reading passage
All matter has properties. A property is the way something looks , taster, feels, sounds, or smells. Size, shape, and colors are also properties.
For example, a broom is hard, but a rabbit’s fur is soft. A piece of icon sinks to the bottom of water, but a leaf floats on the water. An elephant is big, but an ant is very small. Rocks are heavy, but a feater is light.
You can use tools to learn more about the properties. You can use a hand lens to magnify, making a very tiny thing look big.
You can use a balance to tell the weight of an object. Also you can use a ruler to see how long a thing is.
