Who's it for?
This chapter of our middle school physical science tutoring solution will benefit any student who is trying to learn the structure of matter and earn better grades. This resource can help students including those who:
- Struggle with understanding atoms, compounds, elements, states of matter, the periodic table, or any other structure of 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 structure of matter unit
- Cope with ADD or ADHD
- Want to get ahead in physical science
- Don't have access to their science teacher outside of class
Why it works:
- Engaging Tutors: We make learning the structure of 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 physical science tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn the structure of 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.
- Define atoms.
- Understand what elements are.
- Learn how elements come together to form molecules and compounds.
- Explain how atoms and molecules form solids using patterns and crystals.
- Describe the physical and chemical properties of matter.
- Identify the different states of matter.
- Differentiate between physical and chemical changes to matter.
- List the properties of groups and periods in the periodic table.
1. What is An Atom? - Definition & Examples
After watching this video, you will be able to explain what an atom is, how it is structured, what they are made from, and give some examples of elements. A short quiz will follow.
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. What Is a Compound? - Combining Elements with Chemical Bonds
After watching this video, you will be able to explain what a compound is, identify compounds versus regular molecules, and describe the two types of bonding that form compounds. A short quiz will follow.
4. 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.
5. How Atoms & Molecules Form Solids: Patterns & Crystals
After watching this video, you will be able to explain how atoms and molecules form solids, whether in the form of random mixtures or crystal patterns. A short quiz will follow.
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. States of Matter: Solids, Liquids, Gases & Plasma
Learn the four states of matter in the universe: solid, liquid, gas and plasma. Learn about the differences in shape and volume among the four states, which of the states is the most common and why plasma conducts electricity.
8. 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.
