The Scientific Method: Steps, Terms & Examples

1. 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.

How Scientific Observations Lead to Scientific Questioning

2. How Scientific Observations Lead to Scientific Questioning

Scientific observations are a major component of the scientific process because they lead scientists to ask questions about the world around them. These questions may then be refined with continued observation, or they may be tested through experimentation.

How to Evaluate Scientific Questions

3. How to Evaluate Scientific Questions

Learn about what makes a good scientific and testable question. Then look at various ways to improve non-scientific questions to make them more scientific.

Choosing a Method for Investigating a Scientific Question

4. Choosing a Method for Investigating a Scientific Question

Scientists spend their lives investigating the world. But there are many ways a scientist can investigate a topic. Learn about the various methods scientists use to investigate topic, and how they choose a method by understanding their strengths and weaknesses.

Developing a Scientific Hypothesis

5. Developing a Scientific Hypothesis

This video describes how to create a hypothesis and includes the three main things needed to create a strong hypothesis. You'll learn how to make a clear statement that can be both tested and measured.

Experimental Design in Science: Definition & Method

6. 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.

Sampling Techniques In Scientific Investigations

7. Sampling Techniques In Scientific Investigations

We can learn a lot by gathering information from a small subset of a larger group. By sampling this smaller group, scientists can save time and money while still gaining a good understanding of the population as a whole.

Using Appropriate Tools for Scientific Tests & Data Collection

8. Using Appropriate Tools for Scientific Tests & Data Collection

A properly run experiment depends on using the right tools, both for data collection and analysis. In the end, it will save you time, money and frustration to spend some time planning out which tools are most appropriate for your work.

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

9. 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.
