About This Chapter
CBASE Science: Scientific Research Methods - Chapter Summary
The emphasis of this chapter is on scientific research methods. The online videos will teach you about the processes involved in a scientific investigation and encourage your ability to interpret experimental data. Some of the lessons describe the scientific method's major elements and highlight examples of scientific laws while others explain how to create line graphs and use scientific notation. Use your acquired knowledge to answer relevant questions on the CBASE examination. Viewing these video lessons could help you with:
- Learning scientific vocabulary words
- Understanding the scientific method
- Describing the correlation between theory, law and hypothesis
- Explaining how scientific experiments are designed
- Understanding the process of collecting research data and discovering which tools are utilized
- Identifying the metric units for mass, volume, length and more
- Writing numbers using scientific notation
- Exploring examples of scientific investigation
- Drawing logical conclusions and recognizing the main parts of a line graph
- Presenting research findings through oral or written presentations
These and other topics are contained within these short and entertaining video lessons. Study the self-paced lessons online via your wired or wireless device so that you can successfully answer questions on scientific research methods when you get to the science portion of the CBASE examination. All of the lessons consist of educator-developed material and they're delivered by real teachers. You'll discover video, course and quiz tabs along with transcripts that include important terms in bold script. Whenever necessary, submit your questions and receive expert support by using the ask-an-expert function.
CBASE Science: Scientific Research Methods Chapter Objectives
When you're taking the CBASE examination, you'll be required to answer 180 multiple-choice questions. The test's four subject areas are Mathematics, English, Social Studies and Science. Some of the questions on the Science section will require you to have good comprehension of scientific research methods. During the four-hour examination, you can apply your knowledge of the scientific methods of experimental and observation design, interpreting results, and laboratory and field work techniques in the hope of gaining entrance to a teacher education program.
1. Science Vocabulary & Concepts: Study Skills & Word Parts
Learning science presents a unique set of challenges for students. In this lesson, learn the tricks of the trade as we discuss scientific vocabulary and other science study skills.
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. Hypothesis, Theory & Law in Science
In this lesson, learn how to define hypothesis, theory, and law in science. Then, discover the ways that these ideas are related to each other and how they help us to explain the universe around us.
4. 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.
5. How Observational & Field Research Are Used to Collect Data
Psychologists have many different options for where and how to do research. Watch this video to learn more about the difference in field and lab research and the advantages and disadvantages of observational research
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. The Metric System: Units and Conversion
Just like you and your friend communicate using the same language, scientists all over the world need to use the same language when reporting the measurements they make. This language is called the metric system. In this lesson we will cover the metric units for length, mass, volume, density and temperature, and also discuss how to convert among them.
8. Scientific Notation: Definition and Examples
Scientific notation is a special way of writing numbers so they are easier to work with. This lesson will define scientific notations and show some examples of how to convert numbers from standard notation to scientific notation and back.
9. Evaluating Data from Scientific Investigation
After watching this video, you will be able to explain the meaning of the terms 'accuracy' and 'reproducibility,' or precision, as they relate to science experiments. A short quiz will follow.
10. 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.
11. How to Construct Graphs from Data & Interpret Them
After watching this video, you should be able to explain what a graph is, construct a scatter plot, and interpret scatter plots from scientific data. A short quiz will follow.
