About This Chapter
PSSA - Science Grade 8: Scientific Instruments - Chapter Summary
Ensuring that students understand how to properly and safely use scientific instruments when working in the laboratory is of utmost importance. In this test prep chapter, expert instructors guide students through the necessary protocols of using laboratory equipment and materials so they can successfully answer related questions on the PSSA - Science Grade 8 exam. Additional topics reviewed in this chapter include:
- Maintaining data integrity when using scientific instruments
- Components of and uses for the compound microscope
- Types and units of laboratory measurements, including the metric system
- Lab safety equipment
Once students complete each lesson and indicate understanding, offer the multiple-choice lesson quizzes and then the more comprehensive chapter exam to identify whether there are any areas they need to re-examine. Quizzes contain embedded links that will take them directly back to any specific concept they need to review. They can also utilize the printable quiz worksheets for offline studying or as a guide to identify key points while viewing the lessons. If you or the students need any additional help on any of the material covered, instructors are readily available.
1. Techniques to Maintain Data Integrity from Scientific Instruments
In order to be a good scientist, you have to make sure that your data is worthwhile. But how can you be sure of that? This lesson goes over many of the techniques you can use to be sure that your data is both accurate and precise.
2. How to Use Science Lab Equipment & Materials
Learn how to use some common pieces of science lab equipment, including scales, probeware, meters sticks, microscopes, and computers. Learn about setup, calibration, measurement technique, maintenance, and storage.
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.
4. 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.
5. 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.
6. 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.
