1. What is Chemistry? - Definition, History & Branches
Known as the central science, chemistry is integral to our understanding of the natural world around us. In this lesson, you'll be introduced to the field of chemistry, learning about its history and its modern applications.
2. 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.
3. Mass and Weight: Differences and Calculations
We often talk about mass and weight as if they are the same. While they are proportional to each other, they are not, in fact, the same. In this video lesson, you will learn to distinguish between the two, as well as convert one to the other.
4. 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.
5. 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.
6. 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.
7. The Atom
Tune into this lesson to find out what matters about matter. What exactly is an atom? And, how do the atoms that make up the elements in the periodic table differ from one another?
8. What Are Elements?
Look around you. What do you see? Elements are everywhere. They are the building blocks of all matter on Earth. In this lesson, we will discuss what an element is, how elements are written as symbols, and how elements are the building blocks of all matter.
9. Understanding the Relationships between Elements, Molecules & Compounds
Everything on Earth is made of atoms, and sometimes they combine to form new groups of atoms. The sky is the limit when it comes to these combinations, which account for the vast number of things we find in our natural world.
10. Creating Mixtures by Combining Elements & Compounds
Do you really know what's in your tap water? It's not just water - it's a mixture of many different things. In fact, most things are mixtures of different elements and compounds that are physically joined together.
