Ch 1: Praxis Biology: Science Principles - Processes and Disciplines

About This Chapter

This chapter can help you learn about the processes involved in scientific inquiry. These video lessons and quizzes will show you how to form a hypothesis, develop experiments and draw conclusions in preparation for the Praxis Biology exam.

Praxis Biology: Science Principles - Processes and Disciplines

The information in this chapter will give you a solid foundation in the processes and methods used in the scientific process. As you prepare for the Praxis Biology test, you will learn about how to design and perform a scientific experiment as well as engage in scientific research. These lessons will prepare you to correctly answer questions on the following topics:

  • Scientific observation
  • Formulating a hypothesis
  • Experimental design
  • Determining accuracy
  • Reporting results of an experiment
  • How chemistry, math and physics intersect with biology

Experienced instructors will guide you through the concise video lessons, offering examples to explain the concepts. You can test your knowledge and prepare for the exam with the quizzes included at the end of each lesson.

Praxis Biology: Science Principles - Processes and Disciplines Chapter Objectives

Many states require that candidates for teacher certification pass the Praxis examination in the subjects they wish to teach. The Praxis II Biology: Content Knowledge test is for teachers who want to work at the secondary school level. It consists of 150 multiple-choice questions and is available as a paper test or on computer. There is a time limit of two hours.

The test is divided into six sections. The questions on the topics covered in the Processes and Disciplines chapter are in the exam's first section, Basic Principles of Science. This section has 12 questions, which make up 8% of the total exam.

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.

What is Qualitative Observation? - Definition & Example

2. What is Qualitative Observation? - Definition & Example

There are various ways we can observe things. We often use numbers in our observations, but we can also make observations using our senses. These are called qualitative observations, and they are the focus of this lesson.

What is Quantitative Data? - Definition & Examples

3. What is Quantitative Data? - Definition & Examples

Watch this video lesson to find out the difference between saying you have seven apples and saying that those apples are delicious. You will learn about quantitative data and why it is useful.

Experimental Design in Science: Definition & Method

4. 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.

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.

Identifying Potential Hypotheses from a Given Experiment

6. Identifying Potential Hypotheses from a Given Experiment

Experimental designs are dependent on good hypotheses. But we can also look at it the other way and identify a hypothesis from an experiment. In this lesson, we'll work through this process, showing you how to dissect an experiment to identify what is being tested.

Designing an Experiment to Test a Given 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.

Understanding Whether Experimental Designs Match Hypotheses

8. Understanding Whether Experimental Designs Match Hypotheses

Hypotheses and experimental design are two peas in a pod. How you write your hypothesis will greatly influence how you design your experiment. In this lesson, learn about the types of experiments you may run and how you can match your hypothesis to the appropriate one.

Variables & Controls in a Science Experiment

9. 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.

Drawing Logical Conclusions from Experimental Data

10. 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.

Presenting the Scientific Process Orally or in Writing

11. Presenting the Scientific Process Orally or in Writing

Part of being a good scientist involves sharing your work with others. Two of the most common ways this is done is through written works and oral presentations, both of which require a certain amount of care and skill.

Print & Electronic Sources for Scientific Research

12. Print & Electronic Sources for Scientific Research

Sources provide you with helpful background information that support your own work. You can find sources both online and in printed materials. There are benefits and drawbacks to each, so you'll need to consider which is best for you and your project.

Scientific Sources: Accuracy, Reliability & Validity

13. 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.

The Role of Mathematics in Biology

14. The Role of Mathematics in Biology

Mathematics is applied in all major fields of science, including biology. Here, we investigate the different applications of mathematics in biology and explore some examples.

What is Chemical Biology?

15. What is Chemical Biology?

What's the difference between chemical biology and biochemistry? Learn what chemical biology is, and how it may lead to future medical advances. Then see how much you've advanced by taking a quiz.
