Ch 24: Scientific Inquiry & Laboratory Safety

About This Chapter

Brush up on topics associated with scientific inquiry and laboratory safety with the lessons in this chapter. Study up on the basic rules of lab safety, see the definition and examples of scientific investigation and more.

Scientific Inquiry & Laboratory Safety - Chapter Summary

Review the techniques for interpreting charts, tables, and graphs with scientific data, as well as how to draw logical conclusions from data with these engaging video lessons that also cover methods of scientific inquiry and laboratory safety. Learn what is involved in coming up with a sound scientific hypothesis and see definition of experimental design. You can also review the following:

  • Definition and examples of scientific investigation
  • Finding connections between experimental designs and hypotheses
  • Interpreting scientific data
  • Internal validity and its effect on the determination of conclusion
  • Basic rules of lab safety
  • How to work with biological specimens in the lab and out of it

Gauge the amount of information you remember from the chapter by taking the short quizzes at the end of each lesson. You can also contact the instructors if you have any questions.

What is Scientific Investigation? - Definition, Steps & Examples

1. What is Scientific Investigation? - Definition, Steps & Examples

Scientific investigation is the way in which scientists and researchers use a systematic approach to answer questions about the world around us. Read on to find out more. A quiz is provided to test your understanding.

Formulating a Viable Scientific Hypothesis

2. Formulating a Viable Scientific Hypothesis

Constructing a viable scientific hypothesis involves several different factors. In this lesson, you'll explore what separates a good hypothesis from a bad one and how to identify if your hypothesis has been formulated properly.

Experimental Design in Science: Definition & Method

3. 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.

Understanding Whether Experimental Designs Match Hypotheses

4. 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.

Drawing Logical Conclusions from Experimental Data

5. 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.

Interpreting Tables of Scientific Data: Practice Problems

6. 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.

Interpreting Graphs and Charts of Scientific Data: Practice Problems

7. Interpreting Graphs and Charts of Scientific Data: Practice Problems

Do charts and graphs make problem-solving difficult? Complex problems with visual representations can drain your brain during a test. In this lesson, learn three simple rules for solving problems with charts and graphs. We'll try them out as we walk through two sample problems.

Drawing Conclusions Based on Internal Validity

8. Drawing Conclusions Based on Internal Validity

When a researcher gets the results of their study back, how do they know that the independent variable caused the results? In this lesson, we'll look at how internal validity shapes the way researchers draw conclusions about their research.

Laboratory Safety Techniques: Protecting People and Equipment

9. Laboratory Safety Techniques: Protecting People and Equipment

Laboratory safety is not fun, but following the rules ensures that lab activities can be enjoyed by everyone. In this lesson, we cover some basic lab safety rules to follow that will help lab time be both safe and fun.

Working with Biological Specimens Safely in the Lab

10. Working with Biological Specimens Safely in the Lab

Working with biological specimens can be interesting and rewarding. But we need to be careful when handling and disposing of these types of specimens because they do have the potential to do harm both in and out of the lab.
