# Ch 41: MTEL Middle School Math/Science: Research & Experimental Design

### About This Chapter

### 1. What is Scientific Research?

This lesson will discuss important components of scientific research, including the scientific method, peer review, statistical significance, and more!

### 2. 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.

### 3. 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.

### 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.

### 5. Hypothesis, Theory & Law in Science

In this lesson, learn how to define hypothesis, theory, and law in science. Then, discover the ways that these ideas are related to each other and how they help us to explain the universe around us.

### 6. Formulating the Research Hypothesis and Null Hypothesis

After figuring out what you want to study, what is the next step in designing a research experiment? You, the researcher, write a hypothesis and null hypothesis. This lesson explores the process and terminology used in writing a hypothesis and null hypothesis.

### 7. Designing an Experiment to Test a Given Hypothesis

A well-written hypothesis is the key to any well-designed experiment. In this lesson, we'll work through the process of designing an experiment based on the hypothesis it's meant to test and see how the two work to complement each other.

### 8. Variables & Controls in a Science Experiment

After watching this video, you will be able to explain how science experiments are conducted; what variables, controlled variables, and controls are: and why these things are important. A short quiz will follow.
