Teachers, save “Science: Appearance of Rocks” to assign it to your class.

We observe when we use one or more of our senses to find out about objects, events, or living things. An observation is a fact learned directly through the senses. Scientists learn about living and nonliving things through observation. First I want you to watch the video to learn how to make great observations. Next I want you to find and gather 3 different types of rocks and make some of your own observations. The more the rocks differ in appearance the better (and easier) this task will be! When you make your observations, think about its colour, shape, texture, size, and luster. Luster describes how light bounces off a rock or mineral. Words like shiny, metallic, glassy, and dull describe luster. Your task is to make detailed observations and inferences about what kind of rock you have chosen.
