Who's it for?
This chapter of our college-level general chemistry tutoring solution will benefit any student who is trying to learn experimental chemistry and introductory matter and earn better grades. This resource can help students including those who:
- Struggle with understanding the metric system, scientific notation, states of matter or any other experimental chemistry and introductory matter 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 experimental chemistry and introduction to matter 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 experimental chemistry and matter 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 experimental chemistry and matter on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Become familiar with metric system units.
- Learn how to convert among various types of units.
- Understand how to use significant figures and scientific notation.
- Describe the appropriate uses of various types of chemistry lab equipment.
- Compare and contrast the physical and chemical properties of matter.
- Discuss the different states of matter.
- Determine the best method for separating a mixture.
1. 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.
2. 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.
3. 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.
4. 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.
5. Matter: Physical and Chemical Properties
How are substances identified? There are two major ways we can describe a substance: physical properties and chemical properties. Learn about how chemists use properties to classify matter as either a mixture or a pure substance.
6. States of Matter and Chemical Versus Physical Changes to Matter
The world around us is constantly changing. Chemists put those changes into two main categories: physical changes and chemical changes. This lesson will define and provide examples of each.
7. Chromatography, Distillation and Filtration: Methods of Separating Mixtures
What are some ways that mixtures can be separated? Watch this video to explore several examples of ways you can separate a mixture into its individual components.
8. What is Dimensional Analysis? - Definition & Examples
When we measure an object's size or amount, we encounter different units. Sometimes, we need to convert one unit to another, and this is where dimensional analysis comes in. In this lesson, we will learn about dimensional analysis and practice it.
9. What is Fractional Distillation? - Definition & Process
Did you know that fractional distillation is commonly practiced by oil refineries using crude oil for the production of gasoline fuel? In this lesson, learn more about this fascinating process.
10. Using Aliquots in Chemistry: Definition & Function
Did you know a sub-sample is another way to describe an aliquot? In this lesson, we will learn more about aliquots, why they are sub-samples, and their function in chemistry.
