This is a service provided for educators, home schoolers, advanced students, and curious minds. We create videos with teachers notes to augment your lesson plans and enhance your understanding. We also offer written materials to use in the classroom as assignments or extra credit.

We focus on physical sciences, specializing in astronomy, physics, meteorology, and earth science. If you’re looking for a video that shows how an object at rest remains at rest, you’ve come to the wrong place. Our goal is to provide lessons that would be dangerous, difficult, or time-consuming to demonstrate in the classroom. If the experiment can be done, get the equipment and make it so. Hands-on is always better than a video. Before purchasing, you should read About Our Videos.

Purchases are handled securely by PayPal. You can use your PayPal account or any major credit card. Privacy is guaranteed. When you complete the transaction, you’ll receive an immediate link to download your purchase as a zipped file. We thank you for doing business with Heimhenge Enterprises!

Have fun browsing our lessons. You can watch a low resolution preview of every video, no registration required, no strings attached, no email address, phone number, or DNA sample needed. You’re welcome.
