For the #BlueSkyArtShow, I'm going to take "any art, any interpretation" very, very liberally and share this interactive #Desmos graph I made that shows how rainbows are made from #Lights through a water droplet. "Reverse contrast" in the settings so it looks like: www.desmos.com/geometry/pzt...

$A beam of light refracts when it enters a water droplet at an angle; it reflects off the back on the inside, and refracts again when leaving the drop. This spreads the colors of light so that depending on a viewer's position, the drop will appear to glow with a particular color. When many drops in many positions do this, you get the familiar rainbow.$

Happy September, everyone! Whether you're enjoying autumn in the northern hemisphere or spring in the southern hemisphere, we're entering a season of moderate temperatures. I have been able to make some measurements this week...a full analysis to come, but I can share this in the meantime:

Here's how I used #Desmos to model a shadow's path across the ground on the solstice! You may find this method interesting or useful if you plan to join the MEaSURE Project this September, calculating Earth's radius in a global science experiment. youtu.be/F1Pv80Vwukk

Happy equinox! If you're interested in making a measurement, here is a demonstration of the submission process. I also include a review of the results/analysis available to the public. youtu.be/PvO_FaWJnJI

This Friday, March 20th, let's do an experiment! The sun is directly over the equator on the equinox, which means that you can directly determine your latitude with a shadow. If we are east/west of each other, the time difference between our noons gives us a longitude. We can measure the Earth!

Happy 2nd day of Fall! Fortunately I had the day off today (Happy Rosh Hashanah) so I was able to process the data and crunch the numbers. The results and data are available at my website now, but if you want to see a summary, read the thread! sites.google.com/view/themeas...

Unfortunately, it's cloudy where I am today. I was prepared to take three classes outside to measure shadows! But I won't be able to contribute any measurements today. I'll try again in the spring!

1. Find a flat, level surface 2. Set up a vertical ruler 3. Find true North (northern hemisphere) or true South (Southern hemisphere) 4. Wait for the equinox 5. Measure the length of the shadow at solar noon 6. Record the time of solar noon (UTC) 7. Go to the MEaSURE website and submit your data

@petraschwer.bsky.social Thank you for sharing my post! This experiment's first attempt was done with help from a school in Leinfelden-Echterdingen, not far from you!

Hello STEM teachers! As the school year wraps up and you begin to make plans for next year, I've got something you might like to check out! This experiment can be done anywhere in the world, from elementary to advanced. See the video for details! youtu.be/myvEWdLU_1E
