Observing Matter

在B站看见了一个系列视频，据说是美国小学生的自然科学课，刚好拿来学一学英语。下面是做的一些笔记以及自己尝试的一些描述。

All matter has properties.
A property is the way something looks, tastes, feels, sounds, or smells.
Size, shape, and colors are also properties.
For example, a broom is hard, but rabbit's fur is soft. A piece of iron 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 feather 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.

My description:

There are many different matters in the world, we use many ways to observe them.
A hand lens is a magnifying glass, it can make a tiny matter look larger. We can see more details about something we observing with a hand lens.
A balance can get a matter's weight, we can see it is heavy or light.
A ruler is a tool that we can measure how long a matter is. We can finger out that a matter is long or short.
A hand lens, balance and ruler are tools. We use them to observe matters. Size, colors, weight and shape are matters' properties.
Throw an iron into the water, it will sink at the bottom of the water. But if we throw a leaf into the water, it will float on the top of the water. A fellow is soft and rocks are hard. An elephant is large and an ant is small. We use these to describe a matter's property.
