Amusement Park Physics Lessons

We're going to Story Land today! It's a fairy tale themed amusement park for little kids. It's perfect for my daughters and their cousins who are coming with us. Going to Story Land is a good reason to share some science lessons that can be taught through the context of amusement park rides like roller coasters and spinning tea cups.

CK-12 has a lot of interactive simulations for physics and math concepts. One of those is this roller coaster simulator. The voiceover for the simulation is very robotic. The redeeming quality of CK-12's roller coaster simulation is that students can customize the size of the roller coaster to see how the changes they make impact the speed, the potential energy, the kinetic energy, and the heat generated by the roller coaster.
PhET offers lots of lessons and interactives to help students understand various forces in physics. Make sure you look at their list whenever you need help explaining a physics concept to students.
PBS Learning Media offers a handful of resources for teaching and learning about the physics of roller coasters. Energy Transfer in a Roller Coaster is an interactive lesson designed for elementary and middle school students. Energy in a Roller Coaster is a simple interactive graphic that students can use to see how changes in a roller coaster design impact the speed of the roller coaster. Centripetal Force in Roller Coaster Loops is a short video that demonstrates why its not just the harness keeping your seat in a roller coaster.
Teach Engineering offers a hands-on lesson plan for teaching about the physics of roller coasters. In the lesson students build and test model roller coasters to learn about the forces that affect the speed of roller coasters.
How Roller Coasters Affect Your Body is a TED-Ed lesson that begins with the story of the first roller coaster in America and the injuries it caused to riders. The lesson then moves on to explain how the forces of a roller coaster can affect your body, how roller coaster designers account for those forces, and why roller coasters have gotten faster and safer over the years.
CK-12 offers a couple of interactive simulations and lessons about centripetal force. Students can use these on their own or as part of a larger lesson that you lead.
Here's a student-produced video addressing centripetal force in the context of "the tea cup problem." Jump to the two minute mark to see how he enlists the help of his brother to create the explanation.
Planet Nutshell published a concise, animated explanation of centripetal force. You can watch it here or as embedded below.

This five-part course teaches you everything you need to know to create and teach with your own animated explanations. In the course you’ll learn why the process of creating animated explanations is valuable to your students and to you. You’ll learn how to make everything from a simple one-frame animation to a complete animated video. Click here to learn more and get started today!

How to Create & Sell Your Own Digital Products
In this four-part course you’ll learn how to create and sell eBooks, webinars, video courses, lesson plans, and more! And I’ll help you promote your new products! All of the course material is delivered in a series of four weekly emails. Each lesson includes written materials, templates, and video tutorials. You can email me all of your questions as you go through the course. And at the end you can book a one-on-one Zoom call with me! Learn more here and get started here!

Five Video Projects for Almost Every Classroom
In this five-part course you’ll learn how to create and conduct video projects in almost any K-12 classroom! You can do these projects on Chromebooks, iPads, Mac, and Windows computers. Highlights of this course include making green screen videos, creating animated videos, and a variety of ways to create instructional videos. Learn more here and get started here.

If you’ve already taken one of these courses, thank you! Your support makes it possible for me to keep creating resources for teachers.

Why Wet Dogs Are Smelly - Another Lesson Inspired by My Daughters

Spring and summer so far have been exceptionally wet here in Maine. It's starting to make us all a little nutty. Regardless of the weather, our dogs still need to run around and go for walks. A few days ago I took our dogs for a walk in the pouring rain. When I returned my youngest daughter commented on the smell of our wet dogs. Of course, that prompted her sister to then say "why are they so stinky?"

Once again, my daughters raised a question that I've never thought about. I've just always accepted that wet dogs are smelly dogs. As one does when a child asks "why are wet dogs stinky?" I turned to YouTube. Sure enough, I quickly found a SciShow Kids video that addresses that very question.

Why Are Wet Dogs Smelly? does a nice job of explaining to elementary school students that a dog's fur is home to a lot of microbes that become easier for humans to smell when a dog gets wet and then shakes his or her fur.
