Ch 3: NYSTCE Biology: Measurement & Observation

About This Chapter

Let us help you refresh your understanding of various methods of scientific measurement and observation, including uses for the compound microscope as you prepare for the NYSTCE Biology exam. We provide a variety of study aids in addition to our lively video lessons and quizzes.

NYSTCE Biology: Measurement & Observation - Chapter Summary

Let us aid in your preparation for the NYSTCE Biology exam with a review of measurements used in the biology lab and calculations involving them, along with a look at the compound microscope. Our video lessons and quizzes will help you answer questions on topics including:

  • Units and types of laboratory measurements
  • The metric system
  • Parts of the compound microscope
  • Definition and uses of a meniscus
  • How to calculate volume using displacement
  • Types of microscopy
  • How systems in mathematics, technology and science are similar

You can watch these short video lessons on a computer or mobile device. We even provide a worksheet with questions you can print out and study if you're away from the Internet. A Dashboard lets you organize your progress and may even suggest additional courses that could help you.

NYSTCE Biology: Measurement & Observation - Chapter Objectives

Obtaining certification to teach biology in New York State requires passing the NYSTCE Biology exam. The exam has 90 multiple-choice questions that are divided into six subareas. There is one short writing assignment, which makes up a seventh subarea. Questions on observation and measurement are in the Foundations of Scientific Inquiry subarea, which accounts for 17% of the exam's total content. The essay assignment makes up 10% of the exam and also covers material from the Foundations of Scientific Inquiry subarea.

Each of our lessons is accompanied by a short multiple-choice quiz that offers experience in answering questions in a format like you'll face on the exam. The questions ask you to read a short passage, then choose the correct answer. Our quizzes include links to parts of the lessons that contain answers to the questions. If you answer a question incorrectly, it's easy to hop back to the video and review that portion.

Understanding Laboratory Measurements: Units & Types

1. 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.

The Metric System: Units and Conversion

2. 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.

Introduction to the Compound Microscope: Parts & Uses

3. Introduction to the Compound Microscope: Parts & Uses

The compound light microscope is a useful tool in any biology laboratory. In this lesson, you'll be introduced to the parts of a compound microscope, as well as understand the function of each of those parts.

What Is a Meniscus? - Definition, Uses & Lab Examples

4. What Is a Meniscus? - Definition, Uses & Lab Examples

Liquids can be tricky to measure because surface tension causes them to do interesting things like forming a meniscus. In this video lesson you'll learn what a meniscus is, why it forms, and how to correctly read the volume of a liquid using the meniscus at the surface.

Using Displacement to Calculate the Volume of an Object

5. Using Displacement to Calculate the Volume of an Object

Determining the volume of an object is easy if that object is uniform and has a regular shape. For objects that are irregularly shaped, using the edges is not so straightforward, so instead we can measure the volume by displacement.

Microscopy Types & Applications

6. Microscopy Types & Applications

What is microscopy and how do we use it? Learn about the different types of microscopes and the ways we use them for practical purposes. You can then take a quiz and test what you've learned.

Similarities Among Systems in Mathematics, Science & Technology

7. Similarities Among Systems in Mathematics, Science & Technology

How do the concepts of balance and equilibrium extend throughout science and mathematics? How does solving algebraic equations parallel chemical equilibrium within a solution? See how crucial balance is in our universe as well as how mathematics is used to describe these constant equilibriums.
