Save Earth from the evil villain who is draining all the life from it. Following the activity, read more about rocks and soil, and then take a quick quiz to check for understanding.
Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.
By the end of this section, you will be able to do the following:
Explain why an animal’s diet should be balanced and meet the needs of the body
Define the primary components of food
Describe the essential nutrients required for cellular function that cannot be synthesized by the animal body
Explain how energy is produced through diet and digestion
Describe how excess carbohydrates and energy are stored in the body
Student groups compete to design a process that removes the most iron from fortified cereal. Students experiment with different materials using what they know about iron, magnets and forces to design the best process for removing iron from the cereal samples.
What are the state symbols of Colorado? Find them here, along with the date of their adoption, and links to pictures and more information.
Defines the properties of a mineral.
A free CK-12 account is required to view all materials.

In this lesson, students will learn that minerals are a necessary part of our diet. They will learn that different minerals have different functions in the body. More specifically, they will discover that iron is necessary to carry oxygen around the body. In the associated activity, students will design a process that removes the most iron from the cereal.
Photos, illustrations, 3D graphs and animations are part of this investigation into the geology and landforms of the Grand Canyon. Learn detailed information on the formation of the canyon, the rock layers, and the prehistoric life that existed at the time each layer was created.
This video provides insight to mineralogy, petrology and crystallography and how minerals and gems are researched [4:09]
Slice open a rock and look at it under a microscope and you will see are a rainbow of colors which are minerals. Minerals are made up of elements essential to modern life. Watch this video to see the mineral composition of rocks and the many uses of minerals today. Closed caption is available. [2:12]
Here are step-by-step instructions on how to create crystals. This is a great experiment for students to use in learning about the structure and formation of crystals.
Understand how microbes transform minerals in this webcast. How can microbes possibly help curb pollution? [29:16]
Through this series of three lessons, students will gain an understanding of the basics of mineral science. In their investigation they will also work through the scientific process as they practice their observation skills, form hypotheses, and make conclusions. Teachers and students alike will love the easy to understand background information and vibrant photos. Each lesson comes complete with clear learning objectives and instructions, as well as supplemental discussion and explanations. Also provided are the accompanying student handouts and a resource list.
Over 4,700 mineral species descriptions include HTML-linked mineral tables by physical and optical properties of all known valid mineral species.
This National Park Service site has information about these fossil beds in Nebraska and where the name Agate came from.
Rocks cover the earth's surface, including what is below or near human-made structures. With rocks everywhere, breaking rocks can be hazardous and potentially disastrous to people. Students are introduced to three types of material stress related to rocks: compressional, torsional and shear. They learn about rock types (sedimentary, igneous and metamorphic), and about the occurrence of stresses and weathering in nature, including physical, chemical and biological weathering.
Don't be fooled! While color is one way to identify a mineral, it can often be misleading. Quartz is one example of a mineral that can change colors depending on its chemical make-up.
