2. Science Standard 1: The Nature of Science and Technology Indicator 5.1.7: Give examples of materials not present in nature, such as cloth, plastic, and concrete, that have become available because of science and technology.

3. Definitions Cloth-a piece of fabric for a particular purpose. Plastic-any of a group of synthetic or natural organic materials that may be shaped when soft and then hardened. Concrete-a stone-like material used for various structural purposes.

4. Background Information Some materials are not readily available or available in nature. Some materials, such as cloth, plastic, and concrete, need to be man-made. These materials have become available through the use of science and technology. Where would we be without these materials?

5. Purpose The purpose of this activity is for you to design a tool that could be used to help you if you were stranded on a deserted island. You may only use materials that are found on an island. You may also use the clothing youare wearing because it would be with you if youwere stranded. You can’t use materials that are readily available such as plastic and concrete. These materials have become available because of science and technology.

7. Pre-Activity What products would you create to satisfy your needs and wants? How would you make the products, and what materials would you use? If you were stranded on a deserted island, with only the clothes you were wearing, what basic needs and wants would you try to satisfy?

8. How Are They Made? Directions: List at least one material from nature and one man-made material that could be used to make each item. If the item cannot be made with materials from nature, put an X in the blank space.

9. Activity Imagine that you are stranded on a deserted island with only the clothes on your back. Your goal is to construct a tool using only sticks, stones, grass, pine cones, and your clothing if needed. Not all of the materials need to be used, but you must make a tool that can help you in some way. Construct the tool, tell what it is, and what it is used for. Also, tell what materials it is made of. Remember, the only man-made material that may be used is your clothing because you are already wearing it. When construction of the tool is done, state some materials that are man-made that your tool could be made of.

10. Conclusion Questions What are some materials that are not present in nature? -How do you know that it is not present in nature? How do we get materials such as plastic? -How do you know? How has technology affected your life?

11. Summary After doing this project, you should have a great understanding of what materials are readily available in nature and what materials are man-made. You should also be able to create a tool with materials that are available in nature and state that this tool can be made out of many different man-made materials. The most important goal of this lesson is to show students that man-made materials have become available because of science and technology.
