Experimental Design in Science: Definition & Method

1. 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.

Evaluating Data from Scientific Investigation

2. Evaluating Data from Scientific Investigation

After watching this video, you will be able to explain the meaning of the terms 'accuracy' and 'reproducibility,' or precision, as they relate to science experiments. A short quiz will follow.

Finding & Evaluating Sources for Research

3. Finding & Evaluating Sources for Research

Not everything you read on the Internet is true. This video will help you navigate through different online sources and evaluate the validity of those sources to ensure that you can trust the information you use as part of your research.

Scientific Tools and Their Uses

4. Scientific Tools and Their Uses

A scientist relies on tools to help make observations, carry out experiments and take measurements. Learn about the scientific tools used in a lab and the advanced tools used by scientists in the life sciences.

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.

Working with Biological Specimens Safely in the Lab

6. Working with Biological Specimens Safely in the Lab

Working with biological specimens can be interesting and rewarding. But we need to be careful when handling and disposing of these types of specimens because they do have the potential to do harm both in and out of the lab.
