Ch 51: Ohio Graduation Test: Scientific Method & Inquiry

About This Chapter

This chapter will help you study for the Ohio Graduation Test in science. Our series of lessons offers a review of the processes of the scientific method and the different ways scientific data is presented.

Ohio Graduation Test: Scientific Method & Inquiry - Chapter Summary

Review the processes of scientific inquiry by watching our expert instructors in this chapter of short, engaging lesson videos. Use these lessons to improve your understanding of the scientific method, experimental design, data evaluation and the different ways to present scientific findings. After this chapter, you should be prepared for questions on the Ohio Graduation Test (OGT) science exam about:

  • The steps of the scientific method
  • Characteristics of true experiments and experimental design
  • Tools used to conduct scientific tests and collect data
  • Importance of validity and reliability in scientific research
  • Evaluating data, accounting for error and confounding variables
  • Risks of scientific experimentation and scientific safety precautions
  • Different forms of scientific presentations and publications
  • Scientific graphs, charts and tables

To see how much of the information you retained from these lessons, take the short quizzes that accompany them. Then review your quiz results to identify the topics you missed, and use the video tags to return to and review the parts of the lessons that explain them. After you complete the lessons and quizzes of this chapter, test your overall understanding of the chapter by completing the practice chapter exam.

Ohio Graduation Test: Scientific Method & Inquiry Objectives

All high school students in the state of Ohio must pass the all parts of the OGT in order to graduate. The science portion of the OGT is composed of 32 multiple-choice questions, four short-answer questions and two extended-response questions used to measure your understanding of the sciences, including the process of scientific discovery. Our lessons offer a variety of methods to review the material covered in this part of the OGT.

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.

Experimental Design in Science: Definition & Method

2. 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

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.

Designing an Experiment to Test a Given Hypothesis

4. 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.

Sampling Techniques In Scientific Investigations

5. 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.

Using Appropriate Tools for Scientific Tests & Data Collection

6. 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.

Validity and Reliability: How to Assess the Quality of a Research Study

7. Validity and Reliability: How to Assess the Quality of a Research Study

Many psychologists and teachers complete research studies. How can you tell if a study was done well? This lesson will cover many criteria for a good quality study, including types of reliability and validity.

Evaluating Data: Precision, Accuracy & Error

8. Evaluating Data: Precision, Accuracy & Error

The data you present as a scientist needs to be as accurate, precise and error-free as possible. In this lesson, we'll discuss what each of these terms means, as well as how error is introduced into measurements and other data collection.

Identifying Potential Reasons for Inconsistent Experiment Results

9. Identifying Potential Reasons for Inconsistent Experiment Results

Repeating an experiment helps ensure that you designed and implemented it correctly. But what if you don't get the same results each time? In this lesson, we'll explore potential reasons for this and how you might avoid it in the future.

Identifying Sources of Unavoidable Experimental Error

10. Identifying Sources of Unavoidable Experimental Error

Good data are essential for any experiment. But no matter how hard you try, error in your data is unavoidable. In this lesson, you'll learn about the types of unavoidable experimental error to be on the lookout for and how to reduce their occurrence in your data.

Understanding Risks & Taking Safety Precautions in Science Experiments

11. 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.

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.

Presenting the Scientific Process Orally or in Writing

14. 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.

How to Read Scientific Graphs & Charts

15. How to Read Scientific Graphs & Charts

How do scientists summarize their findings with visual aids? In this lesson, explore the different types of tables, charts and graphs that scientists use. Learn to read these effectively as a preview to your science studies.

Interpreting Tables of Scientific Data: Practice Problems

16. Interpreting Tables of Scientific Data: Practice Problems

Complex table problems getting you down? Multi-question, situational problems don't have to be a drag on your testing performance. Learn how to apply three simple rules as we walk through two table problems together.
