Basic Science Lab Skills - Chapter Summary and Learning Objectives

In this chapter, instructors will lead you through lessons on lab safety and equipment, lab measurements and more. You'll learn about the parts of the compound microscope, uses for a meniscus and calculations used to determine the mass of an object. This chapter is designed to teach you about:

  • Lab measurement types
  • Displacement and volume
  • Methods for protecting lab equipment
  • Compound microscopes

Video Objectives
Understanding Laboratory Measurements: Units & Types Outlines the units of measurement for length, volume, mass and temperature that are part of a lab setting.
What Is a Meniscus? - Definition, Uses & Lab Examples Defines meniscus and describes how to read the meniscus of a fluid. Provides examples of fluids that make a meniscus concave along with examples of those that make it convex.
Using Displacement & Volume to Calculate the Mass of an Object Explains how to calculate the mass of an object by measuring its volume.
Common Laboratory Equipment: Types & Uses Identifies commonly used lab equipment. Provides details on the uses for pipettes, graduated cylinders, beakers, balances, Bunsen burners, petri dishes and more.
Laboratory Safety Techniques: Protecting People and Equipment Discusses the importance of lab safety. Highlights common lab safety practices, such as using personal protective equipment, washing hands, handling food and drink, labeling containers and wearing appropriate clothing.

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.

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

2. 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.

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.

Common Laboratory Equipment: Types & Uses

4. 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.

Laboratory Safety Techniques: Protecting People and Equipment

5. 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.

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.
