Not finding what you're looking for? A few suggestions:
• Fewer words might give better results. Look up cats instead of funny cats.
• No need to search with the words videos or for kids included.
• Use related words: If searching for iceberg isn't working, try ice or glacier.
• Is everything spelled correctly?
• Browsing topics might help, too!

Beet Beet, Sugar Beet and how sugar is made
See how sugar is harvested from the sugar beet in this classic and catchy 1979 video from Sesame Street: Beet Beet, Sugar Beet. Some background from Wikipedia: The sugar beet has a conical, white, fleshy root (a ta...
The Wood Wide Web: How trees secretly talk to and share with each other
Trees secretly talk to each other underground. They're passing information and resources to and from each other through a network of mycorrhizal fungi—mykós means fungus and riza means root in Greek—a mat of long, thi...
How To Grow Coral
When visitors at Georgia Aquarium gaze upon the diverse array of colorful corals, [biologist Kim] Stone says many mistake the often stationary specimens for beautiful rocks. But corals are actually living animals—they...
Learning from leaves: Going green with artificial photosynthesis
Releasing too much carbon dioxide into the atmosphere, thanks to the burning of fossil fuels, isn't a good thing. But what if leaves can provide some ideas for how we can turn this 'nuisance gas' into useful chemicals...
The Exhale Bionic Chandelier: Microorganism-filled ‘leaves’ that ‘breathe’
An air purifier, an art object, and a piece of lighting design all in one living, 'breathing' chandelier. This is London-based inventor and bioengineer Julian Melchiorri's Exhale Bionic Chandelier, a microorganism-fil...
Colorscope, an exploration of color across cultures
How do different cultures perceive and use color? Colorscope touches upon those perceptions and uses throughout history in this series of videos from CNN Creative, written and narrated by British art historian and bro...
The seafloor microscope that can reveal corals’ secrets
See the seafloor like you've never seen it before, thanks to this microscope, the first to show 1.6 millimeter-sized coral polyps up close in the wild. An effort to better understand these lifeforms in the face of cor...
How Do Trees Transport Water from Roots to Leaves?
Travel through a part of the water cycle that we don't often think about: Water's journey from the roots of a Douglas fir, upward through hair-thin fibers within the trunk, reaching the tree's photosynthesizing needle...
Dead stuff – The secret ingredient in our food chain
When you picture the lowest levels of the food chain, you might imagine herbivores happily munching on lush, living green plants. But this idyllic image leaves out a huge (and slightly less appetizing) source of nouri...
Why do leaves change color?
The arrival of autumn is a great reason to talk about chemistry: When tree leaves change from green to reds, oranges, yellows, and browns, we're seeing the tree's green chlorophyll fade away, revealing hidden autumnal...
How NASA sees photosynthesis from space + TMBG’s Photosynthesis
This NASA Earth Science video, NASA Sees Photosynthesis From Space, is not only a lesson in how plants use light to make food for themselves, but also demonstrates how changing your perspective ...
Mimosa pudica (touch-me-nots) & rapid plant movement
This is a mimosa pudica, also known as the sensitive plant or a touch-me-not. It is known for its rapid plant movement, moving quickly into a closed, sleep position when touched, shaken, blown at, etc, only to open a...

The dazzling fluorescent colors of corals under actinic lights
The kind of light that we see things in changes how we see those things. This reef tank is shot under actinic light, which will not only facilitate photosynthesis or stimulate light sensitive species, but also changes...
