Video lessons make learning about the scientific method more engaging, helping you retain information better. Thanks to this chapter, you will be better prepared to answer questions on the NJBCT exam.
1. What is Scientific Research?
This lesson will discuss important components of scientific research, including the scientific method, peer review, statistical significance, and more!
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. 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.
4. 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.
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.
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.
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.
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.
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.
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.
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. 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.
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.
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.
