About This Chapter
Using Natural Resources - Chapter Summary
The lessons in this chapter delve into the use of natural resources. You'll find informative discussions of key topics like water resources, the three Rs of reducing solid waste, and NPK fertilizers. Lessons also examine the uses of glasses and ceramics as well as how to prevent corrosion.
You'll get a look at ways to extract metals that are not as damaging to the environment as traditional mining and learn about activities that negatively impact water supply. After completing the chapter, you should be prepared to:
- Define natural resources, renewable resources, and non-renewable resources
- Discuss water treatment and water resource issues
- Explore alternative methods of extracting metals
- Discuss uses of life cycle assessments (LCAs)
- Investigate the three Rs of reducing solid waste (reuse, reduce, and recycle)
- Examine prevention and protection from corrosion
- Describe uses and properties of alloys, glasses, and ceramics
- Understand polymers, thermosoftening, and thermosetting
- Explain the Haber process and its commercial uses
We use short and engaging text and video lessons, which help you easily understand the information presented. Our expert instructors are effective and use plenty of examples. The video timelines allow you to navigate the learning process by going directly to the topics of your choice. Each lesson is accompanied by a brief multiple-choice quiz to test your knowledge. Full video transcripts are also available.
1. What Are Natural Resources? - Definition & Types
Natural resources are materials provided by the Earth that humans can use to make more complex (human-made) products. In this lesson, you will learn some examples of natural resources and how to classify them.
2. Renewable & Non-Renewable Resources: Definition & Differences
We use a variety of Earth's resources, but not all of them will be around forever. This lesson explains the difference between resources that can be regenerated for our use and those that are gone after they are used once.
3. Water Treatment: Improving Water Quality
In this lesson, you will learn how water is purified for drinking, and how wastewater is treated before being put back into the environment. You will also learn about water purification issues in developing countries.
4. Water Resource Issues: Activities Affecting the Water Supply
This video lesson describes water resources issues such as aquifer depletion, overdrawing surface waters and salinization of irrigated soil. You will also learn about the impacts of activities affecting water resources.
5. The 3 Rs of Reducing Solid Waste: Reuse, Reduce & Recycle
Reduce, reuse, recycle! In this lesson, we will explore the three Rs of reducing solid waste. We will also investigate examples of each of the three Rs, and how people can do their part to help reduce solid waste.
6. Corrosion: Definition, Prevention & Protection
You've seen metals corrode even if you weren't aware of what was happening. This lesson will define corrosion, and then will examine ways to protect metals, thus preventing corrosion.
7. Alloys: Uses & Properties
In this lesson, we will discuss how alloys are made. We will also learn about the properties and the wide ranging uses of the various different alloys.
8. Types of Glasses: Uses & Properties
In this lesson, you'll learn about the different common types of glass that are available. You'll also learn how different chemical compositions of glass lead to different properties and uses.
9. Types of Ceramics: Uses & Properties
In chemistry, ceramics refer to more than simply pottery and plates. In this lesson, we will learn about the different types of ceramics and the uses of these ceramics.
10. Polymers, Thermosoftening & Thermosetting
In this lesson, we will learn about the difference between thermosoftening and thermosetting polymers. We will also explore one kind of thermosoftening polymer, polyethylene.
11. The Haber Process: Commercial Uses & Chemistry
The Haber Process makes getting nitrogen from the atmosphere a possibility. This lesson will describe the Haber Process before discussing some of the challenges ammonia manufacturers must overcome when using the Haber Process.
12. NPK Fertilizers: Definition & Uses
Fertilizers probably don't sound exciting, but they actually are! This lesson will explore what NPK means, as well as how the elements are obtained for this type of fertilizer.
