Video Script: <strong>Elements</strong>,<br />
<strong>Compounds</strong>, and <strong>Mixtures</strong><br />
1. Look around you for a few seconds. What do you see?<br />
2. Perhaps you see the inside of a building including windows and doors.<br />
3. Maybe you see desks and chairs.<br />
4. Or, maybe you see books, papers, pencils, and pens.<br />
5. Perhaps you even see other people.<br />
6. Have you ever wondered what all these things are made of?<br />
7. Or, have you ever wondered what makes something like this piece of wood. . .<br />
8. . . . different from this piece of copper wire?<br />
9. What is the difference between ocean water. . .<br />
10. . . . and lake water?<br />
11. During the next few minutes we are going to explore many of these questions and<br />
others. . .<br />
12. . . . as we examine some of the fascinating characteristics of elements, compounds,<br />
and mixtures.<br />
13. Graphic Transition – Small Particles<br />
14. This is a piece of copper flashing.<br />
15. It is sometimes used on roofs to help protect wood underneath it.<br />
16. Let us cut it in half, then cut it in half again, and then cut it in half again.<br />
17. You Decide! If it were possible to continue to cut the copper in half, what is the<br />
smallest possible piece that we could make?<br />
18. The smallest possible piece is an atom. What is an atom?<br />
19. An atom is the smallest possible piece of a pure substance that still has the properties<br />
of that substance.<br />
20. Atoms are the building blocks of matter.<br />
21. All matter, including the human body is made up of atoms.<br />
22. Over hundreds of years, scientists have worked hard to try to understand the<br />
characteristics of matter. This is a simplified diagram of an atom magnified millions<br />
of times.<br />
23. One of the many things scientists discovered is that there are many different kinds<br />
of atoms. They also learned that the characteristics of matter are determined by the<br />
kinds of atoms that are in a specific type of matter.<br />
24. A substance or a piece of matter that is made up of just one kind of atom is called an<br />
element.<br />
