About This Chapter
NYSTCE Physics: Scientific Experimentation - Chapter Summary
Watch the lesson videos of this chapter to review how to design and conduct laboratory research safely and effectively. These lesson videos are taught by expert instructors who will explain laboratory procedures, uses of scientific equipment and the components of a scientific experiment. After this chapter you should be better prepared to answer questions on:
- Experimental design and the scientific method
- Using common laboratory equipment
- Laboratory safety and safety equipment
- Handling chemicals and biological materials
- Understanding laboratory measurements
- The different forms of scientific data
- Reading tables, figures and other scientific reports
- Assessing validity and reliability
If you have any questions about the material in this chapter be sure to ask our instructors for assistance so that you can master the material before you take the New York State Teacher Certification Examinations (NYSTCE) Physics Content Specialty Test (CST). Further improve your understanding of the material by completing the lesson worksheets and quizzes. If think you would still benefit from an alternative way of reviewing the material try reading the lesson transcripts that present the same material but in written format.
NYSTCE Physics: Scientific Experimentation Objectives
If you are interested in becoming a certified physics teacher in the state of New York you will need to take the NYSTCE Physics CST. This exam is a computer-based test with 90 multiple-choice and one constructed-response questions. Test takers are given four hours and 15 minutes to complete these questions.
Nineteen percent of the exam is composed of multiple-choice questions on the foundations of scientific inquiry and another 10% is covered by the constructed-response assignment on the foundations of scientific inquiry. Use this chapter to improve you understanding of the processes and components of conducting scientific experiments to be prepared for related questions on the NYSTCE Physics CST.
1. 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.
2. Common Laboratory Equipment: Types & Uses
Biologists use all kinds of equipment in their labs to run their experiments. In this lesson, you'll identify some of the most common pieces of equipment as well as when you should or shouldn't use them.
3. Chemistry Lab Equipment: Supplies, Glassware & More
When you bake a cake, you use different tools for each step in the process: a bowl for mixing, cups for measuring ingredients and an oven for baking. In this lesson, you will discover the name and purpose of many of the different tools that are used in the chemistry lab.
4. 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.
5. Standard Laboratory Safety Equipment
Even with proper precautions, lab accidents do happen. When they do, knowing what safety equipment is in your lab, where it is located, and how to use it can prevent further harm to both the lab and the people working in it.
6. Handling Laboratory Solutions, Chemicals & Biological Materials
Working in a laboratory requires careful attention, both for safety and successful completion of tasks. Learn about the many ways biological and chemical substances need to be properly prepared, identified, stored, dispensed, and disposed of.
7. How to Preserve, Stain & Mount Microscope Specimens
Microscopes are incredible tools for observing the tiniest of organisms. Here we will identify the types of slides that can be made and describe how to best preserve, stain, and mount specimens. At the end, you can test yourself with a brief quiz.
8. Understanding Laboratory Measurements: Units & Types
There are many different units that can be used for measurements. This may not only lead to incorrect data measurements, but also to confusion about which units are most appropriate. Therefore, a standard set of units is used for each type of measurement in the biology lab.
9. 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.
10. How to Interpret Tables, Graphs & Charts of Scientific Data: Practice Problems
In this lesson, we will look at some practice problems involving tables, graph, and charts. We will specifically look at x- and y-axis graphs, pie charts, and bar graphs.
11. Significant Figures and Scientific Notation
Are 7.5 grams and 7.50 grams the same? How do scientists represent very large and very small quantities? Find out the answers to these questions in this video.
12. 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.
