Students will review:
This chapter helps students review the concepts in the measurement and problem solving in chemistry unit of a standard high school chemistry course. Topics covered include:
- Uncertainty in chemistry
- SI base
- Unit conversion
- Significant figures
- Measuring temperature
1. Measurements & Uncertainty in Science
In this lesson, you will discover the importance of precision and accuracy in science while learning to make measurements. Also, you will understand how to perform calculations with measurements that conserve precision and limit uncertainty.
2. Elements of the SI: Base & Derived Units
Discover what we mean by SI units. Then explore SI units further by learning about all the base units, and several examples of the derived units that make up the system.
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. 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.
5. 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.
6. Factor-Label Method in Chemistry: Definition, Examples & Practice Problems
This lesson introduces the factor-label method for converting units. The basic technique is included as well as several examples of metric unit conversions and basic molar mass conversions found in chemistry.
7. Thermometer: Definition, Types & Examples
Whenever you get the forecast for the day, check your body temperature, or use the air conditioning, you are using a thermometer. Learn about the different kinds of thermometers, and discover how they work.
8. Measuring Temperature in the Lab: Instruments & Process
In this lesson, discover what temperature is a measurement of while learning how to properly measure temperature in a lab. Learn about the important instruments needed for this essential lab skill.
9. Bradford Protein Assay: Advantages & Disadvantages
There are several methods used to measure proteins. In this lesson we will examine the advantages and disadvantages of using the Bradford protein assay.
10. Bradford Protein Assay: Principle, Protocol & Calculations
The Bradford Protein Assay is one of the methods used to measure protein concentration in a sample. In this lesson we will learn how it works and the steps in this method.
11. Biuret Test: Definition, Procedure & Reagent
This lesson describes a common test for proteins called the biuret test. A description of the reagent used in the biuret test as well as the procedure for measuring protein concentration will be covered.
12. Lowry Protein Assay: Principle, Protocol & Mechanism
The Lowry protein assay is a common method used to measure the protein concentration in products. In this lesson we will learn the steps in this method and how the reaction works.
