About This Chapter
Chemistry Lab Basics - Chapter Summary and Learning Objectives
Working effectively in the chemistry lab requires that you know and follow commonly accepted procedures to remain safe and to acquire dependable results. In addition, students working in the lab must have several crucial sets of knowledge for measurement purposes and for expression of numeric properties. In this chapter, our instructors will guide you through the methods typically used in a chemistry lab and offer interesting examples as clarification. Watch the video lessons as many times as needed and complete the quick, multiple-choice quizzes to measure your understanding. After working your way through these lessons, you should be able to accomplish the following:
- Convert one unit to another unit while solving chemistry problems
- Use various types of tools correctly in the chemistry lab
- Make effective use of the metric system
- Understand how to represent very small or very large quantities in scientific calculations
|Unit Conversion and Dimensional Analysis||Use dimensional analysis or the factor-label method to solve one-step and multi-step problems.|
|Chemistry Lab Equipment: Supplies, Glassware & More||Learn the purposes and names of a variety of chemistry lab tools.|
|The Metric System: Units and Conversion||Review the metric system's units and practice converting between them.|
|Significant Figures and Scientific Notation||Understand how very large or very small quantities are represented by scientists.|
1. Unit Conversion and Dimensional Analysis
How is solving a chemistry problem like playing dominoes? Watch this lesson to find out how you can use your domino skills to solve almost any chemistry problem.
2. 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.
3. 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.
4. 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.
