Science is the process of observing the world and trying to explain and predict what will happen. Often, as more information becomes available, the accepted scientific theories must change.

How to Avoid Bias in Scientific Investigations

4. How to Avoid Bias in Scientific Investigations

In this video lesson, you will learn what it takes to conduct a proper scientific investigation while doing your best to avoid any possibility of bias. Learn where possible sources of bias can come from and what you can do about it.

What is Critical Thinking? - Definition, Skills & Meaning

5. What is Critical Thinking? - Definition, Skills & Meaning

Critical thinking is a term that we hear a lot, but many people don't really stop to think about what it means or how to use it. This lesson will tell you exactly what it means and make you realize that the average person largely ignores critical thinking.

Unexpected Observations & Results in Experiments

6. Unexpected Observations & Results in Experiments

Observations and experimental results do not always agree with what we expect. However, these results are not necessarily mistakes, and in this lesson we'll take a look at how they can even lead to useful discoveries.
