# Learn Physics the Easy Way

**In Fascinating Physics, we will study the laws of nature governing movement, energy, and sound. Further, we will study the forces of electricity, magnetism, gravity, and the atomic nucleus. As the course progresses, you will begin to understand how mathematical formulas summarize and predict events around us.**

# Learn Physics the Easy Way

### In Fascinating Chemistry, you will learn the four ways that atoms bond to each other to create molecules, and how each bond helps determine the properties of the resulting molecule.

### Join Dr. Margulies for a fascinating course as he helps you learn how these special properties explain our everyday world — from water freezing to nuclear energy to food to metals to weather, and more!

#### Dr. Margulies created this lesson to help explain the fundamentals of chemistry – in just a little over an hour.

#### If you’re a parent, this lesson will enable you to follow — and even guide — your child’s progress through chemistry. If you’re a student, the lesson will give you a heads up and a head start.

# What our customers say

# “

**My 14 year old son is both gifted and dyslexic.**He is extremely interested in science. I have searched for years for a

**good audiovisual science program**for him. I was so happy to find yours. I am not sure if you are actively marketing the product to dyslexics and other folks with print disabilities or not. I think you would do very well within that market. It is hard to find anything. That being said, I do think it is

**helpful to have the print version to follow along with**and love that y’all post it on the site. –Nina

#### Shari Rosenman

**My 12 year old son seems to be enjoying the videos very much and believes he’s learning a lot. This is one of the subjects he does on his own, without prodding from me.**It’s hard to find a science program that can capture a student’s interest and I think this program does that.

#### Alane Wiegman

Thank you so very much! I really love this website. I was a Chemistry minor in college,although there’s a lot I don’t remember, and there are definitely things that must be newer science, or at least more detailed, as I am learning things along with my sons!

**Thanks SO much to Dr. Margulies for this gift to our children! It is so simple and complete.**
