NYSTCE Biology: Laboratory Basics - Chapter Summary
Use this chapter's lessons to refresh your understanding of basic laboratory procedures, including how to use common equipment and perform standard tasks. Our videos will help you prepare for NYSTCE Biology exam questions on topics such as:
- Types and uses of laboratory equipment
- Safety precautions for the laboratory
- How to handle laboratory solutions, biological materials and chemicals
- Dissection practices and alternative methods
- Ways to stain and mount microscope specimens
- Ethical issues regarding studies with living organisms
- Beer's law
- Definitions of and uses for centrifugation and chromatography
You can watch these lessons on a computer, smartphone or tablet any time your schedule allows. Each includes a written transcript, with key phrases and terms highlighted, so you can read along with the narrator. The Dashboard feature lets you keep up with your progress, and you can use its Ask-an-Expert feature to contact the instructors if you have questions.
NYSTCE Biology: Laboratory Basics Chapter Objectives
Passing the NYSTCE Biology test is one of New York State's requirements for certification to teach the subject in a public school. The test contains 90 multiple-choice questions, divided into six subareas, and one short essay, which is in its own subarea. Questions on the material covered in this chapter's lessons are in the Foundations of Scientific Inquiry subarea, which makes up 17% of the NYSTCE Biology test's total content. The written assignment accounts for 10% of the exam, and it also reflects material from the Foundations of Scientific Inquiry subarea.
Because the quizzes that accompany our lessons also consist of multiple-choice questions, they offer good practice in taking a test in this format. The quizzes allow you to evaluate your knowledge. There are links on the answer key to our videos, so if you answer a question incorrectly, it's easy to jump back to the lesson and review that information.
1. 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.
2. 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.
3. 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.
4. Dissection Techniques & Alternatives
In this lesson, we'll talk about the importance of dissection, and hopefully about how to enjoy it! We'll introduce some safety rules and tools, and alternatives to dissection as well.
5. 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.
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. The Ethics of Biological Studies With Living Organisms
In this lesson, you'll learn about some general ethical considerations that must be taken when procuring and treating animals used in biological studies. Afterward, take our quiz to see what you've learned.
8. Beer's Law: Absorbance & Concentration
Beer's Law relates the absorbency of a substance to its chemical concentration. In this lesson, we'll review light transmittance and absorbance and how Beer's Law is used to determine chemical concentrations.
9. What is Centrifugation? - Definition, Process & Uses
Astronauts, hospitals, and you depend upon centrifugation all of the time! This lesson will explain how centrifugation works and then will discuss some uses of the centrifuge. Following your exploration of that information, you can test your knowledge with a quiz.
10. What is Chromatography? - Definition, Types & Uses
Chromatography is a versatile method of separating many different kinds of chemical mixtures. In this lesson, learn the different types and uses of the technique.
