Ch 2: Laboratory Equipment and Procedures
About This Chapter
Laboratory Equipment and Procedures - Chapter Summary
Take another look at the uses of common lab glassware - such as beakers, flasks and graduated cylinders - and review the types of equipment needed to take measurements, perform dissections and heat materials. You'll also re-examine procedures designed to keep you safe in the lab and go over the use of eyewash stations, emergency showers and ventilation hoods.
Additional lessons show you how to properly handle chemicals, preserve biological materials and prepare specimens for examination under a microscope. The chapter concludes with a review of the metric system. Topics of discussion are listed below:
- Uses of lab glassware and supplies
- Lab safety equipment and procedures
- Methods for preparing lab experiments
- Metric units and conversion factors
This chapter includes illustrated videos lasting around five minutes each, as well as transcripts. Access content in whichever format fits your learning style, and take the multiple-choice quizzes that follow each lesson to see how much of the material you're familiar with. You can also complete a more comprehensive chapter test.
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. 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.
6. 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.
