Read the text and do the tasks to it.
Have you ever asked why a bee sting hurts, or what makes lemons taste sour? Have you ever wondered why nails rust, or why water rolls off a duck's feathers? These are the kinds of questions scientists try to answer in the science called chemistry. If you have thought about these things. you might decide to find out more about chemistry, the study of matter.
From the beginning of human life, people have always wanted to know what things are made of. Even in ancient times, before the Greeks, humans discovered that they could make hard bricks for building houses if they mixed together clay, water, and straw, and then dried the mixture in the sun. They noticed that water from the ocean tasted saltier than water from a stream. They learned that rocks would not bun. They noticed that different types of matter behaved differently.
The ancient Greeks tried to find out matter step by step. They wrote down their ideas, and we can still read what they thought. They said that everything is made out of four basic kinds of matter: earth, air, fire and water. Today, scientists know that isn't right, but people still respect the ideas of the Greeks, because they studied the natural world so carefully.
Later on, people called alchemists began to study matter for their own gain. They thought they could become rich by changing cheap metals like iron into expensive gold. They tried everything they could think of, but no gold ever appeared. Even though the alchemists did not succeed, their experiments taught them many new things about matter.
Today, chemists not only learn what past ages knew about matter, they also gain new knowledge. Now we know more about matter than ever before. But chemists still have plenty to learn. They are still finding out how different materials can be mixed together to make new things.
