14 Lessons in Chapter 1: Scientific Inquiry & Reflection
How to Evaluate Scientific Questions

1. 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

2. 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

3. 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.

Using Appropriate Tools for Scientific Tests & Data Collection

4. 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.

Experimental Design in Science: Definition & Method

5. 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.

Connecting the Steps of the Scientific Method

6. Connecting the Steps of the Scientific Method

While the scientific method is divided into different steps, each of those steps is connected to the others. From making observations to drawing conclusions, the logical order and flow is what makes this process work so well in science.

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.

Scientific Sources: Accuracy, Reliability & Validity

8. Scientific Sources: Accuracy, Reliability & Validity

It's important to use other sources to support your work, but what's even more important is to use the right ones. Sources should be valid, reliable, and accurate, but it's not always easy to tell which ones meet these criteria.

Methods for Improving Measurement Reliability

9. Methods for Improving Measurement Reliability

Reliability is the consistency of the results of a measurement tool. But, what causes a tool to have low reliability? And, what can be done to improve reliability? In this lesson, we'll answer both of those questions.

Understanding Risks & Taking Safety Precautions in Science Experiments

10. Understanding Risks & Taking Safety Precautions in Science Experiments

An important step in designing your experiment involves identifying and evaluating any potential safety risks. Knowing what these risks are ahead of time can help you avoid accidents and dangerous situations, which helps keep the experiment safe and fun for all.

What is Peer Review in Science? - Definition, Process & Examples

11. What is Peer Review in Science? - Definition, Process & Examples

Interested in learning how scientific literature is fact-checked and accepted? In this lesson, you'll learn about the peer review process that happens in science. Examples of the peer review process are included to further your understanding of the lesson.

How to Evaluate Scientific Claims & Arguments

12. How to Evaluate Scientific Claims & Arguments

When you hear about the new scientific discovery, how can you be sure that it's true? Learn how to evaluate scientific claims and arguments, and then test your new skills with a quiz.

Drawing Logical Conclusions from Experimental Data

13. Drawing Logical Conclusions from Experimental Data

Experimental results are what scientists like to share with each other, but it's important to understand what those data mean. We do this in the final step of the experimental process, when we draw meaningful conclusions from the results we obtained.

Careers in the Sciences: Typical Courses & Degrees

14. Careers in the Sciences: Typical Courses & Degrees

Natural sciences use the scientific method to investigate concepts and ideas. This lesson will review the many types of career options and coursework a student of science can expect.
