Science matters
Do you like science? Whatever you think of science, there is no doubt that it can be very surprising.
Science tries to answer many of the questions that we like to ask about the world around us. Do you know, for example, that lightning is ten times hotter than the Sun? Or that a hundred million micro-organisms live in your mouth?
The three main areas of science are Biology, Chemistry and Physics. Biology is the study of living things. It includes the fields of botany, zoology, ecology and environmental science. Chemistry is the study of the building blocks of nature and how they combine to form the solids, liquids and gases that make up everything. Physics is the branch of science that deals with matter and energy and how they interact.
Science tries to answer questions such as: Why do we see lightning before we hear thunder? Why do we need to breathe in more air during exercise? What do oil and coal come from?
Physicists have shown us that light travels faster than sound. It is the fastest thing we know. Biologists explain that when we do exercise, the cells in our body need more oxygen. Chemists have found that oil and coal come from plants and animals that lived millions of years ago.
The text talks about:
- The importance of science.
- Ecology, botany and zoology are considered branches of Biology.
- The important discoveries that science has discovered about the world around us.
