The mining of our country’s natural resources is not just a simple matter of finding the desired ore and digging it up. Important economic and environmental considerations are involved in any mining venture. These include property costs, mining equipment costs, operational costs, and land reclamation costs. Fines for violations of environmental regulations may also be incurred. If a mining corporation is to make a profit, the value of the recovered ore must be greater than the sum of all of its mining costs plus any environmental fines. In this lab you will create a mining corporation and attempt to run a cookie mining operation that is both profitable and environmentally sound.
Students will simulate the action of and in some cases the consequences of mining for minerals.

Each student will keep a science journal during each of the four seasons. Students will record observations of the general outdoor environment they visit and then will make observations of one specific item from the habitat in each season. At the end of the school year, students will make comparisons of their seasonal drawings and share the results with the class. The purpose of the activity is to introduce students to the concept of using a science journal to record information, to have students use science tools to make scientific observations and to make observational drawings in nature and compare the results throughout the seasons. After completing this activity, students will know about seasonal changes in a particular habitat. They will learn how to make detailed observations, record their results, make comparisons, and share information using a standard format.

Using a color chart, students will make observations outside during each of the four seasons. During each session, they will try to find as many colors as possible and record what they see. As a class, they will make charts describing the colors they find in each season. At the end of the school year, students will compare their results and generate conclusions about variations in colors in nature both within a season and between different seasons. The purpose of this activity is to provide the opportunity for students to make observations in nature and compare their results, to help students understand seasonal changes as they relate to colors in their environment, and to engage students in active observation and recording skills. After completing this activity, students will understand how colors in nature relate to their local environment and to seasonal changes within that environment. Students will practice observation and recording skills, make comprehensive comparisons, and will form a hypothesis based on the information they have assembled throughout the school year.
