Join Dr Charlotte Uhlenbroek as she treks into northwest Rwanda to meet a family of critically endangered mountain gorillas for the first time. This was filmed for the BBC nature documentary series Cousins (2000).

In the archives, meet more gorillas and watch one of our favorite ape videos: an orangutan family spends quiet time together in the jungle.

In 1961, an interactive exhibition called Mathematica: A World of Numbers… and Beyond inaugurated the new science wing at Los Angeles’ California Museum of Science and Industry. Sponsored by IBM, it was an innovative exhibit designed by husband and wife team Charles and Ray Eames, and lucky for us, it included five short animations that explored a handful of math concepts. Watch three of our favorites:

Above, 2ⁿ – “a story about the exponential growth of numbers raised to powers.” Below, Symmetry and testing for degrees of it:

Also, Topology – how a closed curve dissects a plane into inside and outside sections:

And in the archives, don’t miss this iconic Eames film: Powers of Ten.

From PBS’ Adventures in Learning, Jennifer Cooper hosts an Electric Dough playdate to make and test circuits. For this project, developed by engineering educator AnnMarie Thomas, you’ll need homemade conductive play dough and insulating play dough, a battery pack, batteries (we highly recommend these rechargeables), and light emitting diodes/LEDS.
