A unit on
ROCKS AND MINERALS
Bonnie Glasgold, P.S. 101, Brooklyn, New York
OVERVIEW: This is a series of lessons developed on the exploration and investigation of rocks and minerals. The students will learn what the properties of rocks are, how to distinguish among the different types of rocks, and do various experiments with rocks. They will investigate the hardness of rocks, the effect of acid on certain rocks containing limestone, and perform streak tests to determine a rock's mineral content. They will learn the three types of rocks and how to classify them according to their properties. They will learn what the rock cycle is and compare it to other cycles on Earth. Students will have the opportunity to do many laboratory experiments, including the scratch test for hardness. The students will be using the computer as a tool for creating webs, completing vocabulary databases, importing graphics, and research. They will also use a digital camera and insert those pictures into their documents.
Student Level: Grades 3-5
Major Goals and Instructional Objectives:
1. Students will use their senses to become familiar with the characteristics of rocks and minerals.
2. Students will be able to sort minerals on the basis of similarities and differences in identified properties.
3. Students will become familiar with the vocabulary associated with rocks and minerals.
4. Students will become familiar with the three types of rocks (igneous, metamorphic and sedimentary).
5. Students will become familiar with the rock cycle.
6. Students will learn the uses of rocks and minerals.
7. Students will learn their birthstones and related history.
8. Students will conduct hands-on experiments to determine the hardness of rocks, affects of acid, attraction to magnets, and test for mineral color.
9. Students will use technology to enhance their research, create graphs, rock cycles, import pictures, and take pictures with a digital camera and insert them into their document.
Timeline: 6-8 classroom periods (approximately 45 minutes each).
Setting: Science classroom, homeroom class, computer lab, Museum of Natural History, any park or backyard, a quarry, a riverbed, Delaware Water Gap, and the shore.
