The Kid Should See This.
Follow @thekidshouldsee on Twitter!
There's just so much science, nature, music, art, technology, storytelling and assorted good stuff out there that my kids (and maybe your kids) haven't seen. It's most likely not stuff that was made for them...
But we don't underestimate kids around here.
Kid-friendly not-made-for-kids videos for all! Collected by Rion Nakaya and her three four year old co-curator.
Tip Jar: Curating this blog takes work! If you like the videos on this site, please support the science education projects that we've picked on DonorsChoose.org.

Why do we yawn? The kiddo isn’t often into all of the great science-content videos that are a bit heavier on the talking (and many of them are more for older kids anyways), but he stuck with this particular one — I’m sure seeing the animals helped, as did his direct relationship with yawning. And we learned something. And we yawned a lot!

From TEDEd, there is a five finger trick for understanding and remembering the five processes — small population, non-random mating, mutations, gene flow, adaptation — that impact evolution (ie. the changes in the gene pool of a population from generation to generation). This video, narrated by Paul Andersen and animated by Alan Foreman, is seriously so excellent.

The circulatory system consisting of the heart, arteries, capillaries, and veins, is the pumping mechanism that transports blood throughout the body. In the heart, the left ventricle contracts, pushing red blood cells into the aorta, the body’s largest artery. From here, blood moves through a series of increasingly smaller arteries, until it reaches a capillary, the junction between arteries and veins. Here oxygen molecules detach from the red blood cells and slip across the capillary wall into body tissue.
Now de-oxygenated, blood begins its return to the heart. It passes through increasingly larger veins to eventually reach the right atrium. It enters the right ventricle, which pumps it through the pulmonary arteries into the lungs, to pick up more oxygen. Oxygenated, blood reenters the left atrium, moves into the left ventricle, and the blood’s journey begins again.
Nothing like riding through the body to get the point across!

Discovered by a Washington, D.C., lawyer in search of antique furniture, this is truly a Cabinet of Wonders, for inside is the 1700-specimen personal collection of 19th Century British naturalist, field biologist and contemporary of Charles Darwin, Alfred Russel Wallace.
From the Washington Post:
There are butterflies and beetles, moths and shells. There’s a small bird. Flies. Bees. Praying mantises. Tarantulas. Seedpods. A hornet’s nest… “I think it’s a fabulous thing,” said David Grimaldi, curator of invertebrate zoology at the American Museum of Natural History in New York. “I think it’s a national treasure, actually.”

About 4,000 species of cockroaches are known to science, and all but the leaproach scuttle on the ground. (Zoologist Mike) Picker and his colleague Jonathan Colville discovered the leaproach in 2006 as the insects hopped around a field of sedge grass in South Africa…
The new study reveals the leaproach uses its legs much like grasshoppers do, and yet — ounce for ounce — the leaproach far out-jumps locusts. While a grasshopper can jump up to 20 body lengths, a leaproach can sail forward 48 body lengths…
“They’re extremely accurate, and they don’t just sit around,” (Mike Picker) said. “They’re always moving, moving, moving, jumping, jumping, jumping.”
