Fairy Tale Physics

The Fairy Tale Physics series combines beautifully illustrated fairy tales with foundational physics concepts to create a whimsical educational adventure. For ages 10-12. They can be read in any order, and they’re now the bestselling children’s science books on Amazon!

Newton’s Laws: A Fairy Tale

Newton’s Laws: A Fairy Tale follows the story of Kip, the youngest of three sons who is gifted only a single apple with which to go into the world and make his fortune.

He encounters a mathematical wizard named Newton, whose arch-rival Leibnitz is attempting to take over the kingdom. The old king has recently passed away, and the law states that whoever is able to create three laws and make the whole kingdom follow those laws will become the next king. Newton has a clever plan to invent three laws that everyone already follows, and Kip offers to help him. Together they journey to the capital, discovering Newton’s three laws of motion along the way.

 Newton’s Laws may seem simple, especially because we’ve all heard them already, but they’re more complicated than they seem, and most of us have incorrect intuitions about them. I wrote this book to help students build an intuitive foundation that corrects these misconceptions. (The biggest one is that objects require force to move – my free body diagram worksheet focuses on this, too.)

Light: A Fairy Tale

Prince John has recently been crowned king. He wants to be a good king, however he has spent most of his life reading about slaying dragons and rescuing princesses, and feels an enormous amount of pressure from the fourteen portraits of his illustrious forebears staring down at him from the walls of the throne room.

Luckily, a mysterious witch appears with a magical candle that might be the answer to all John’s problems…

In the candle are the ghosts of the most powerful light mages: Einstein, Snell, deBroglie, and Young. And together these famous physicists teach him about light and color, so that he can bring illumination to his kingdom.

Adventure Workbooks!

The best way to learn is through doing. In this series, I’m taking some abstract physics or math (or both!) concepts, creating a story that involves those concepts, and then crafting a series of fun, hands-on activities to go along with the story. For each of these activities, you can download the PDF version for free, and the story that goes along with it, or you can buy a printed spiral notebook version (I print through Lulu rather than Amazon specifically because I love spiral notebooks so much. Much easier to write in.)

More Soon!

I hope to make more of these soon - if you tried out the Starlight Starship Adventure, I’d love to hear what you thought!

Non-Fiction

I have a couple of non-fiction series on Amazon. My algebra series is a set of basic workbooks focused on building foundational skills. They’re especially focused on the small details I see most students have difficulty with. Electric Circuits is part of the Stick Figure Physics series, which is a series of short (math-filled) eBooks that explain physics topics with stick figures.

Math Notebooks

One thing I do with most of my students is coach them on how to take notes. Notes aren’t just a way to record information for later use; they’re a tool for processing information.

The note-taking process I teach involves writing down the major ideas and equations, while mostly just following along with the lecture, thinking about the concepts. That way you record the most important information, but you’re thinking about and engaging with the content, rather than just copying what’s written on the board.

For all my students, I want math to be an enjoyable experience. Part of that is picking a notebook that they love writing in. Especially for students with ADHD, having really detailed notes that they can refer back to can be really empowering.

I know there are tons of beautiful notebooks out there, but I wasn’t finding any that had all the features I wanted, so I worked with an illustrator to create these. I wanted them to be really beautiful in addition to encouraging good note-taking.

Here’s what makes them different than the typical spiral:

  • Numbered Pages

  • Table of Contents

  • Lined Paper and Graph Paper on Every Page

  • Space for Important Equations

  • Space for Questions

I also write fantasy novels! I write humorous, character-driven fantasy stories with a lot of speculative world building and magic systems, usually with awkward, anxious, or over-thinking protagonists.
