1. 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.
2. 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.
3. How Compounds and Molecules Are Built From Elements
Did you know that elements are like people and have different personalities? A few elements are very shy and love to be left alone. Others are very social and prefer to hang out with friends. In this lesson we will discuss how elements build molecules and compounds.
4. Pure Substance in Chemistry: Definition, Properties & Examples
This lesson introduces the concept of the pure substance. The impact of purity on the physical and chemical properties are discussed and several examples are explored along the way.
5. 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.
6. Classifying Substances by Their Physical Properties
After watching this video, you will be able to explain what physical properties are and use them to classify some common substances. A short quiz will follow.
7. 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.
8. 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.
9. How to Construct Graphs from Data
This video describes how to create a line graph and explains the four main parts that graphs need to contain: 1. previously collected data, 2. picture representations, 3. use of the correct graph type, and 4. labels. This lesson also covers dependent and independent variables.
10. Density: Definition, Formula & Practice Problems
In this lesson, you'll learn about density, the way in which density can be calculated from mass and volume, and that density of substances are constant. You'll get to calculate densities of various materials in different situations.
