About This Chapter
TExES Chemistry: Equipment, Safety & Measurements - Chapter Summary
This chapter contains short videos on equipment, measurements and safety designed to help you prepare for the TExES Chemistry exam. You'll review common chemistry lab equipment as well as its uses. Once you finish this chapter, you should be able to do the following:
- Outline the supplies and glassware used in a chemistry lab
- Demonstrate proper lab safety techniques for protecting people and equipment
- List standard laboratory safety equipment
- Discuss the safe handling of lab chemicals, solutions and biological materials
- Preserve, stain and mount microscope specimens
- Identify the procedures of basic first aid
- Explain the units and different types of laboratory measurements
- Describe the units and conversion of the metric system
Take your time as you work through this self-paced chapter, reviewing as many or as few of the videos as you need to feel confident for the test. Along with each lesson, we've included a self-assessment quiz so you can be sure you're ready to move on to other topics. Print off the lesson transcripts to study key facts and terms offline.
1. Common Laboratory Equipment: Types & Uses
Biologists use all kinds of equipment in their labs to run their experiments. In this lesson, you'll identify some of the most common pieces of equipment as well as when you should or shouldn't use them.
2. Chemistry Lab Equipment: Supplies, Glassware & More
When you bake a cake, you use different tools for each step in the process: a bowl for mixing, cups for measuring ingredients and an oven for baking. In this lesson, you will discover the name and purpose of many of the different tools that are used in the chemistry lab.
3. Laboratory Safety Techniques: Protecting People and Equipment
Laboratory safety is not fun, but following the rules ensures that lab activities can be enjoyed by everyone. In this lesson, we cover some basic lab safety rules to follow that will help lab time be both safe and fun.
4. Standard Laboratory Safety Equipment
Even with proper precautions, lab accidents do happen. When they do, knowing what safety equipment is in your lab, where it is located, and how to use it can prevent further harm to both the lab and the people working in it.
5. Handling Laboratory Solutions, Chemicals & Biological Materials
Working in a laboratory requires careful attention, both for safety and successful completion of tasks. Learn about the many ways biological and chemical substances need to be properly prepared, identified, stored, dispensed, and disposed of.
6. How to Preserve, Stain & Mount Microscope Specimens
Microscopes are incredible tools for observing the tiniest of organisms. Here we will identify the types of slides that can be made and describe how to best preserve, stain, and mount specimens. At the end, you can test yourself with a brief quiz.
7. Basic First Aid: Procedures & Guide
This lesson will briefly discuss basic first aid. We will cover a number of topics and provide an overview of what to do in certain situations. Included will be minor problems, emergency issues, and how to decide when to call 911.
8. Understanding Laboratory Measurements: Units & Types
There are many different units that can be used for measurements. This may not only lead to incorrect data measurements, but also to confusion about which units are most appropriate. Therefore, a standard set of units is used for each type of measurement in the biology lab.
9. The Metric System: Units and Conversion
Just like you and your friend communicate using the same language, scientists all over the world need to use the same language when reporting the measurements they make. This language is called the metric system. In this lesson we will cover the metric units for length, mass, volume, density and temperature, and also discuss how to convert among them.
