Everything around you is made up of matter, even the air that is invisible to you. But matter can take different forms. Scientists classify matter into groups called states.
Write an expository essay about the three main states of matter. To do so, you will research matter and how it changes from state to state. Here are some questions to guide your research:
What are the three main states of matter?
How can matter change states?
What kind of experiments can be done to test matter?
What are the "new" states of matter?
Are you ready? Begin by visiting the Web sites in Step 2. Look for answers to the questions above, and write down what you learn in the note-taking boxes.
You may use search engines to research other Web sites. Or research states of matter in the library. When you are ready, follow Steps 3 and 4 to write your expository essay.
