Energy can be potential (like a stretched-out rubber band waiting to snap) or kinetic (like the molecules that vibrate within any substance). And though we can't exactly see it, every time we cook dinner or shiver on a cold night, we know it's there. George Zaidan and Charles Morton get excited about energy.Lesson by George Zaidan and Charles Morton, animation by Pew36 Animation Studios. Learn more about your ad choices.

A mockingbird can match the sounds around it — including car alarms. These are just a few of the 4,000 species of songbirds. How do these birds learn songs? How do they know to mimic the songs of their own species? Are they born knowing how to sing? Partha P. Mitra illuminates the beautiful world of birdsong.Lesson by Partha P.
