Ch 1: Scientific Inquiry, Technology & Engineering

About This Chapter

This chapter helps you familiarize yourself with process of performing scientific inquiry in technology and engineering. Lessons cover experimental design, data evaluation, technological advancements, and more.

Scientific Inquiry, Technology & Engineering - Chapter Summary

When conducting an experiment, there are many questions to consider before even starting to gather information. Not only do you need to have a goal or hypothesis in mind, you must consider the ways you use certain data, tools, and sampling techniques. When the experiment is complete, you must consider the data and conclusions presented not only for readability but also for reliability. This chapter helps you understand these key concepts related to scientific inquiry. Lesson topics include:

  • The scientific method
  • Experimental and engineering design
  • Hypotheses and conclusions
  • Sampling and other data collection tools
  • Evaluating data, including validity and reliability
  • Reading graphs, charts, and tables
  • Risks and benefits of scientific research

In this chapter, our expert instructors explain the basic aspects of conducting scientific research. These short, engaging lessons help you ensure your understanding of each topic before moving onto the next. You can gauge your knowledge with the quiz provided. If you get any questions wrong, use the provided links to jump directly to the point in the lesson that explains that topic.

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.

How to Read Scientific Graphs & Charts

9. 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

10. 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.

Reaching & Applying Scientific Conclusions

11. Reaching & Applying Scientific Conclusions

In this lesson we'll look at the basics of inquiry investigations in science. After learning how to analyze data, we'll determine the steps for making conclusions and comparing alternate conclusions in science.

Engineering Design: Definition & Process

12. Engineering Design: Definition & Process

In this lesson, we will define engineering design and explain the engineering design process from defining the problem to testing and redesigning the final product.

Scientific Research & Technological Advancements: Risks & Benefits

13. Scientific Research & Technological Advancements: Risks & Benefits

How are science and technology related? What are the risks and benefits of technological advancement? Learn how technology has improved our lives and created potential problems. After, take a quiz to see how your knowledge has advanced!
