    Space Junk Joyride

    by

    I don’t get nearly enough chances to use Celestia in my classroom. I’ve loved messing around with Celestia for years, but it’s the rare student who shares my enthusiasm for astronomy. In class I will use Celestia to demonstrate gravitational orbits – moons around planets, planets and comets around suns, …

    High (Voltage) Wire Act

    by

    My brother-in-law Peter visited last year and showed me and my wife some of his favorite short videos on YouTube. When I saw this one featuring a man inspecting high voltage lines, I knew that I would show it to my students. It’s a lovely little video narrated by the …

    The Electromagnetic Spectrum

    by

    A couple of years ago, when my team of physics teachers started building instruction around the topic of electromagnetic radiation, I began assembling a list of different common uses of EM radiation. This list would provide a basis of information to use in our written instruction, as well as suggest …

    The Sun in Various Wavelengths

    by

    My physics curriculum has shifted in response to our new state frameworks, and one shift has been a greater emphasis on electromagnetic radiation. I’ve been having fun concocting new examples and demonstrations (including an “in-house” field trip to our metal fabrication shop to experience welding).

    This spring my class was …

    A Story About Weather and Teaching

    by
    Physics as Story

    I think of physics as a kind of story. It’s actually a huge collection of stories, the result of working to understand every physical phenomenon under the sun (and beyond). In the physics classroom I am therefore a storyteller, and I endeavor to help my students become …

    Quick Electromagnetism Demo Videos

    by

    One of my students this past year had a medical condition that required him to be out of school for an extended time. In situations like this, I usually aggregate all the instructional material for a unit into a single file called a Portfolio PDF. Notes, homework, worksheets, quizzes, …

    It seems that a lot of our instructi9onal design projects involve bringing some sort of technological improvement to an organization or community. This was certainly true in our case. Hey, here’s a great idea, efficient cookstoves, we’ve designed them and now we’d like you, the Low-Tech Gurus, to design a …

    WWW Drive

    by

    All the files I have generated in the course of my Master’s Degree program are located on Google Drive. Sometimes this is required because there will be collaborative writing or editing of documents, or because an instructor wishes to leave comments on a document. Until recently, I have been able …

    Gravity

    This was the assignment for INTE 5680: Create a 30-second video that illustrates a concept using no spoken word. I’m a physics teacher, and always looking for ways to make invisible concepts more visible. So I chose the concept of gravity. Can you tell this is the first smartphone video …

    Let’s Make a Rocket!

    by

    After all the reading for this unit, I wanted to create something that really took advantage of a smartphone’s strengths while avoiding its weaknesses. Since I’m pretty handy with websites, I created a web app (essentially a single-page website).

    First I used Photoshop to create a collection of graphics. I’ve …

    DaVinci Man Waits for the Bus
