I need help with my science class. My teacher wants us to come up with property tests for many different substances to indentify them. I need three property tests for: Coal, Rope, Cloth, Plastic, Paper, Bean, Copper Granuals, Sand, Flower Petal and Rubber. Can you help me find property tests for these substances?

1. Did your teacher specify physical properties or chemical properties? Here are two sites, one that explains and gives examples of physical properties and another that explains and gives examples of chemical properties.

http://en.wikipedia.org/wiki/Chemical_property

For example, copper granules might be defined with a melting point for the copper as well as a color. Both of these are physical properties. A flower petal will have a color and probably an odor. Both are physical properties.
