Common Laboratory Equipment: Types & Uses

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.

Chemistry Lab Equipment: Supplies, Glassware & More

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.

Laboratory Safety Techniques: Protecting People and Equipment

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.

Standard Laboratory Safety Equipment

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.

Handling Laboratory Solutions, Chemicals & Biological Materials

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.

How to Preserve, Stain & Mount Microscope Specimens

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.

Understanding Laboratory Measurements: Units & Types

7. 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

8. 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.

What is Scientific Research?

9. What is Scientific Research?

This lesson will discuss important components of scientific research, including the scientific method, peer review, statistical significance, and more!

The Scientific Method: Steps, Terms & Examples

10. The Scientific Method: Steps, Terms & Examples

The scientific method is more than just hypotheses and experiments. In this lesson, we'll explore the themes and variations that make up the world of science.

Experimental Design in Science: Definition & Method

11. Experimental Design in Science: Definition & Method

What are the requirements of a scientific experiment? How do scientists turn hypotheses into theories and laws? Learn the answers to these questions and more in this lesson on the design of scientific experiments.

Qualitative vs. Quantitative Data in Various Research Methods

12. Qualitative vs. Quantitative Data in Various Research Methods

Qualitative data and quantitative data are both useful in research, but it is important to understand the differences between the two. Learn how to differentiate the two types of data in this lesson.

Interpreting Graphs and Charts of Scientific Data: Practice Problems

13. Interpreting Graphs and Charts of Scientific Data: Practice Problems

Do charts and graphs make problem-solving difficult? Complex problems with visual representations can drain your brain during a test. In this lesson, learn three simple rules for solving problems with charts and graphs. We'll try them out as we walk through two sample problems.

Significant Figures and Scientific Notation

14. Significant Figures and Scientific Notation

Are 7.5 grams and 7.50 grams the same? How do scientists represent very large and very small quantities? Find out the answers to these questions in this video.

Validity and Reliability: How to Assess the Quality of a Research Study

15. Validity and Reliability: How to Assess the Quality of a Research Study

Many psychologists and teachers complete research studies. How can you tell if a study was done well? This lesson will cover many criteria for a good quality study, including types of reliability and validity.

Unifying Concepts Common to All Sciences

16. Unifying Concepts Common to All Sciences

After completing this lesson, you will be able to explain what science is and describe some concepts and ideas that are common across all sciences. A short quiz will follow.

The History of Science: Events, Contributions & Theories

17. The History of Science: Events, Contributions & Theories

In this lesson, we discuss a few significant events in science's history. We will see how science has changed over the years as we start to question what we think we know.
