Who's it for?
This chapter of our middle school physical science tutoring solution will benefit any student who is trying to learn reactions and earn better grades. This resource can help students including those who:
- Struggle with understanding chemical reactions, reactant atoms and molecules, phase change, pH, or any other reactions 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 reactions 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 reactions 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 reactions on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Learn how to balance chemical equations.
- Explain how new products are formed from chemical reactions.
- Become familiar with the different types of phase changes.
- Determine whether a solution is neutral, acidic or basic.
1. Chemical Reactions and Balancing Chemical Equations
In this lesson, you'll learn how to balance a chemical reaction equation using the conservation of matter law. You'll also learn how to write both word and formula equations, what the subscripts after a letter mean and what the numbers in front of compounds mean.
2. How Chemical Reactions Form New Products
After watching this video, you will be able to explain what a chemical reaction is and how the products can have completely different properties to the reactants. A short quiz will follow.
3. Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition
Substances on Earth can exist in one of four phases, but mostly, they exist in one of three: solid, liquid or gas. Learn the six changes of phase: freezing, melting, condensation, vaporization, sublimation and deposition.
4. Acidic, Basic & Neutral Solutions: Determining pH
After watching this video, you will be able to explain the difference between acidic, basic, and neutral solutions and explain the concept of pH. A short quiz will follow.
