Jim Mueller

Welcome to Physics on!

Jim’s current series is finished, but five months of physics lessons remain archived on the site. Link below!


Physics MayWelcome to an approachable, enjoyable, and effective way of learning physics. I like to call myself “Science Jim,” and I have been teaching physics to homeschool students for more than 10 years. So what makes my lessons unique?

A comfortable, humorous style.

I use an entertaining approach that makes learning physics fun!

A light-on-math approach to physics.

I teach the concepts first, the math later.

Hands-on activities and experiments.

Each lesson is filled with hands-on activities tailor-made for each lesson plan.

Lessons that build on each other.

The lessons are sequential, cumulative, and focused on very specific learning goals.  Each lesson provides another step to understanding physics concepts.

So Bring Science Alive!


Now to This Week’s Lesson (May 13-31)

This is the final class in the Magnetism and Electricity series. Look for new Physics lessons from Jim Mueller in June!


We’ve come a long way with this magnetism thing, and hopefully you’re feeling pretty good about how magnetism works and what it does. This lesson, we’re going to use what we’ve learned to make simple versions of two gadgets that you use every day.


Let’s start with the slightly simpler gadget. Let’s make a speaker! Now to understand what’s happening here, we need to take a trip down memory lane to the last lesson, “Magnetism and Electricity.” Remember, electricity is moving electrons, and what do moving electrons create? . . . a magnetic field, right? Also, remember that a magnetic field, when moved near a metal that can conduct electricity, will create an electric current in that metal. (You did this in the last lesson when you did the Ins and Outs of Electricity experiment.)

Magnetism can create electricity and electricity can create magnetism. Now, let’s take a quick look at sound. Sound is created by something vibrating. . . .

“Science Jim” Mueller has a BA from Lake Forest College and an MS from Aurora University. He worked as an environmental educator from 1989 to 1994. The following eight years he worked at a small children’s science museum in Carbondale, Illinois, six of those years as the executive director. Since 2002, Jim has been developing and teaching a physics curriculum specifically for homeschoolers. He has created books, web sites, movies, and, most recently, live web classes for students all over the world. He uses an entertaining and humorous approach with all of his materials, which make his products quite unique in the world of education.

Science Jim, his wife, Science Mary Beth, and his kids, Science Ben and Science Sarah, live in Chapel Hill, North Carolina, where they enjoy their chickens, woodland wanders, music, and board games—that is, when they are not cleaning up after science experiments, of course!
