Each fall, millions of monarch butterflies migrate to California and Mexico for winter. North American monarchs are the only butterflies that make such a massive journey (up to 4,830 kilometers/3,000 miles). They use the sun to ensure that they stay on course and on cloudy days Earth’s magnetic field as a kind of backup navigational system. (read more here)

Sixth-Grader’s Science Fair Finding Shocks Ecologists

"When 12-year-old Lauren Arrington heard about her sixth-grade science project, she knew she wanted to study lionfish. Growing up in Jupiter, Fla., she saw them in the ocean while snorkeling and fishing with her dad.

Her project showed that the lionfish can survive in nearly fresh water. The results blew away professional ecologists. The invasive species has no predators on the Florida coast, so if they were to migrate upstream in rivers, they could pose a threat to the ecosystem.”

Going Outside: The Physics Of A Curveball

Charlie and his friends are going outside to investigate some awesome sports stuff! In this episode they figure out the secret to throwing a curveball, a crazy swooping baseball pitch. Turns out it’s all about physics! Spin the ball the right way and boom, you have a major league caliber pitch … it’s that easy.

One of the challenges for the Summer Intern skill is Make Something with the DIY API so we got together a few resources for getting started!

If you want to dive right in to some code examples you can check out this JSFiddle.

If you want a more thorough walkthrough this example repo should do the trick.

And as always the official API documentation can be found at docs.diy.org.

Finally we’re fielding questions about using the API on this project!

Happy coding!
