Ch 6: Praxis Biology: Laboratory Equipment & Measurements

About This Chapter

When it comes to your biology lab, keeping it stocked with the proper equipment and materials is essential for a great student experience. This chapter reviews the lab equipment and measurement material on the Praxis Biology exam.

Praxis Biology: Laboratory Equipment & Measurements - Chapter Summary

Inside a classroom laboratory, students will want to be able to demonstrate the safe handling of all materials and equipment available to them. The video lessons contained in the Laboratory Equipment & Measurements chapter of this Praxis Biology course will ensure you have a solid grasp on everything in the lab so that your students will be comfortable with you as an instructor. This section of the course covers the following topics:

  • Centrifugation
  • Measuring with scales, meters and gauges
  • Calculating with displacement
  • Using a meniscus
  • The compound microscope
  • Microscopy types
  • Chromatography
  • Dissection
  • Microscope specimens

If a particular topic or lesson in the Laboratory Equipment & Measurements chapter is giving you any trouble, you can access it immediately by utilizing the timeline located below the video presentation. The chapter also contains a number of printable worksheets. If you'll be away from your computer for awhile, take them with you and review on the go in order to prepare for the actual exam.

What is Centrifugation? - Definition, Process & Uses

1. What is Centrifugation? - Definition, Process & Uses

Astronauts, hospitals, and you depend upon centrifugation all of the time! This lesson will explain how centrifugation works and then will discuss some uses of the centrifuge. Following your exploration of that information, you can test your knowledge with a quiz.

How to Take Measurements with Scales, Meters & Gauges

2. How to Take Measurements with Scales, Meters & Gauges

In the real world, we take measurements all the time. Measurements are taken when you drive and when you weigh yourself, for example. Watch this video lesson to learn how you can take measurements of things that are important.

Using Displacement to Calculate the Volume of an Object

3. Using Displacement to Calculate the Volume of an Object

Determining the volume of an object is easy if that object is uniform and has a regular shape. For objects that are irregularly shaped, using the edges is not so straightforward, so instead we can measure the volume by displacement.

What Is a Meniscus? - Definition, Uses & Lab Examples

4. What Is a Meniscus? - Definition, Uses & Lab Examples

Liquids can be tricky to measure because surface tension causes them to do interesting things like forming a meniscus. In this video lesson you'll learn what a meniscus is, why it forms, and how to correctly read the volume of a liquid using the meniscus at the surface.

Introduction to the Compound Microscope: Parts & Uses

5. Introduction to the Compound Microscope: Parts & Uses

The compound light microscope is a useful tool in any biology laboratory. In this lesson, you'll be introduced to the parts of a compound microscope, as well as understand the function of each of those parts.

Microscopy Types & Applications

6. Microscopy Types & Applications

What is microscopy and how do we use it? Learn about the different types of microscopes and the ways we use them for practical purposes. Take a quiz and see what you've learned

What is Chromatography? - Definition, Types & Uses

7. What is Chromatography? - Definition, Types & Uses

Chromatography is a versatile method of separating many different kinds of chemical mixtures. In this lesson, learn the different types and uses of the technique.

Dissection Techniques & Alternatives

8. Dissection Techniques & Alternatives

In this lesson, we'll talk about the importance of dissection, and hopefully about how to enjoy it! We'll introduce some safety rules and tools, and alternatives to dissection as well.

How to Preserve, Stain & Mount Microscope Specimens

9. 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.
