Who's it for?
This chapter of our chemistry tutoring solution will benefit any student who is trying to learn about measurement and problem solving and earn better grades. This resource can help students including those who:
- Struggle with understanding the metric system, the distinction between accuracy and precision, scientific notation or any other measurement and problem solving topic
- Have limited time for studying
- Want a cost effective way to supplement their science learning
- Prefer learning science visually
- Find themselves failing or close to failing their measurement and problem solving unit
- Cope with ADD or ADHD
- Want to get ahead in chemistry
- Don't have access to their science teacher outside of class
Why it works:
- Engaging Tutors: We make learning about measurement and problem solving simple and fun.
- Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
- Consistent High Quality: Unlike a live chemistry tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about measurement and problem solving on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Understand that measurements in chemistry are uncertain.
- List the SI base units and their derivatives.
- Convert among common metric units.
- Learn how to use scientific notation.
- Explain how to measure 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. 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.
