Ch 2: FTCE Biology: Basic Laboratory Concepts & Measurement

About This Chapter

Study information on lab basics concerning equipment and procedures. This chapter contains numerous video lessons that can help get you ready to answer questions about lab concepts on the FTCE Biology exam.

FTCE Biology: Basic Laboratory Concepts & Measurement - Chapter Summary

You'll achieve a strong understanding of lab basics, such as calculating volume with displacement and the metric system, in this chapter's video lessons taught by our professional instructors. The chapter also addresses the compound microscope along with microscopy types.

You will see material that covers the meniscus of a liquid and terminology for the direction of a meniscus' curve. You can also review lessons on procedures for taking measurements with meters, scales and gauges. This chapter has the following learning targets that can help you prepare for the FTCE Biology:

  • List the metric units for mass, volume and length
  • Describe the general conditions that warrant a gauge for measurement
  • Explain how displacement is used to figure out volume
  • Discuss compound microscope parts and their functions
  • Highlight the differences between the main microscopy types

This chapter's learning resources are designed to help you effectively retain the information presented in our engaging and brief videos. You can easily get to specific video points that you wish to review by using the jump feature in the video timelines. Each video has a corresponding lesson transcript. Use these transcripts to review the key terms and main points of each lesson covered. If you wish to get a quick and helpful assessment of your grasp of the material after you have watched the video lessons, you can take the corresponding practice quizzes.

FTCE Biology Objectives

The FTCE Biology exam is a teacher certification exam for aspiring biology teachers in Florida. Designed for those interested in teaching grades 6-12, this exam is computer-based and made up entirely of multiple-choice questions. Knowledge of lab concepts and measurements is tested in the first competency, which makes up 18% of the exam and covers investigative processes in the science field. You'll have 2.5 hours to complete this exam.

6 Lessons in Chapter 2: FTCE Biology: Basic Laboratory Concepts & Measurement
Understanding Laboratory Measurements: Units & Types

1. 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.

The Metric System: Units and Conversion

2. 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.

How to Take Measurements with Scales, Meters & Gauges

3. 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

4. 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

5. 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

6. 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.
