About This Chapter
Performing Scientific Investigations - Chapter Summary
Our chapter on performing scientific investigations contains concise video lessons that outline these subjects clearly. Just a few of these include the development of scientific theories, the scientific method and formulating scientific hypotheses, as well as the ways scientific observations lead to scientific questioning. This chapter is designed to assist you in doing the following:
- Discuss the method associated with experimental design in science
- Design an experiment to test a given hypothesis
- Outline different kinds of research methods
- Differentiate between the kinds of research variables
- Identify scientific investigation sampling techniques
- Explain the safety regulations and concerns for conducting scientific research
- Take safety precautions and understand risks involved when performing science experiments
- Use appropriate tools for scientific tests and data collection
You can take your time as you work through this interesting chapter, using the video tabs feature to go back and review any of the videos as needed. For quick offline review, print out our lesson transcripts to make handy study guides. Each lesson is accompanied by a short quiz, and you'll also find a comprehensive test at the end of the chapter.
1. The Development of Scientific Theories
It takes quite a bit of time to develop a scientific theory, and it is a rigorous process. This lesson will describe what scientific theories are and how they are developed by scientists.
2. 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.
3. 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.
4. How Scientific Observations Lead to Scientific Questioning
Scientific observations are a major component of the scientific process because they lead scientists to ask questions about the world around them. These questions may then be refined with continued observation, or they may be tested through experimentation.
5. 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.
6. 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.
7. What Are The Different Kinds of Research Methods?
This lesson will go over some important research methods, including observation, correlation, and experimentation, as well as examples of each type of methodology.
8. Research Variables: Dependent, Independent, Control, Extraneous & Moderator
This lesson explores the terminology of experimental design. What are variables? How do they influence each other? Is it possible that you are seeing connections that don't actually exist?
9. 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.
10. Conducting Scientific Research: Safety Concerns & Regulations
When scientists conduct research, safety is a top concern. Learn about the kinds of hazards a scientist faces depending on the kind of work that they do, as well as some risks with scientific research. Plus, see how safety regulations protect all of us.
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.
12. 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.
