Scientific Ways of Thinking

1. Scientific Ways of Thinking

Are you interested in becoming a scientist? Science is all about gaining knowledge by asking good questions, making observations, testing your ideas and drawing conclusions. With a little practice, you can learn to think like a scientist.

What Are Life Sciences?

2. What Are Life Sciences?

The life sciences study all types of living things. Branches of the life science study things from the tiniest microorganisms to the largest animals. Learn about the many branches of the life sciences and what it's like to work in these fields.

Life Science Theories

3. Life Science Theories

In the life sciences there are many theories that explain how life works. However, before these theories became widely accepted, they had to be put to the test. In this lesson, you will learn how ideas become theories.

The Scientific Method: Steps, Terms & Examples

4. 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

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.

Scientific Tools and Their Uses

6. 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.

Conducting Scientific Research: Safety Concerns & Regulations

7. Conducting Scientific Research: Safety Concerns & Regulations

When scientists conduct research, safety is a top concern. Learn about the kinds of hazards a scientist faces depending on the kind of work that they do, as well as some risks with scientific research. Plus, see how safety regulations protect all of us.

Science Vocabulary & Concepts: Study Skills & Word Parts

8. Science Vocabulary & Concepts: Study Skills & Word Parts
