Jessi helps Squeaks learn about why foods can be so many tasty-looking colors!

In this video Paul Andersen explains how biogeochemical cycles move required nutrients through the abiotic and biotic spheres on our planet. Matter on the Earth is conserved so producers must receive required nutrients through the water...

There's a game of Tetris happening on a global scale: The playing space is planet Earth, and all those pesky, stacking blocks represent carbon dioxide -- a greenhouse gas that is piling up ever more rapidly as we burn the fossil fuels...

More than 90% of the plants on Earth are angiosperms, flowering plants whose seeds are enclosed inside fruit. And they’re everywhere -- but exactly how and when these plants came to be so ubiquitous is one of the most stubborn questions...

Around the world there are more than 600 plant species that supplement a regular diet of sunlight, water and soil with insects, frogs and even rats. Flies, tadpoles and beetles fall prey to the remarkable, predatory antics of carnivorous...

Plants don’t have brains or muscles, and yet some of them can perform such feats as eating insects or following the sun. Scientists haven’t completely figured out how this happens, but they do have some pretty strong leads.

Carbs are pinned to be the villains in many diets, but those poor guys are just misunderstood.

Even if you don't want to eat them, your apple cores still have plenty of energy left to give. SciShow explores how cities are capturing that energy and turning it into fuel.

A quarter of all prescription drugs in the U.S. come from substances that are found only in plants. In this episode of SciShow, we take a look at four of these talented plants who make our lives better.

If you were a jackrabbit in the desert, you'd be glad to stumble across a cactus: the flesh of these plants is a water source for many animals. Known for their spines and succulent stems, cacti of all shapes and sizes have evolved to not...

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 nourishment: dead stuff....

Plants can get sick, but since they don’t walk around sneezing on each other, the things that infect them need some very weird strategies to spread.

Conventional meat production causes harm to our environment and presents risks to global health, but people aren't going to eat less meat unless we give them alternatives that cost the same (or less) and that taste the same (or better)....

Thanks to the University of Minnesota for sponsoring this video! http://twin-cities.umn.edu/ Morocco has 3/4 of the world’s known reserves of rock phosphate, our main source of phosphorus, so Morocco may be key to our long-term ability...

Why do dogs eat grass? A look at your pup’s wild relatives may give you a sense of what dogs’ diets are really like.

Flowers tend not to own calendars, so how do they know when to bloom?

A few weeks ago we started an experiment where we planted some seeds to see how they would grow! Today we get to check out our results!

Want to learn more? Here are some keywords to get your googling started: - Pollination: the process by which pollen is transferred to the female reproductive organs of seed plants - Pollinator: the agent that moves the pollen - Abiotic...

Photosynthesis is an essential part of the exchange between humans and plants. Amanda Ooten walks us through the process of photosynthesis, also discussing the relationship between photosynthesis and carbohydrates, starch, and fiber --...

Jessi and Squeaks are busy working in their garden, and they'd like to share one trick that keeps their plants happy!

What happens when you can't do aerobic cellular respiration because oxygen isn't available? Explore fermentation with The Amoeba Sisters! This video focuses on alcoholic fermentation and lactic acid fermentation, and it also mentions how...

Mister Brown and Squeaks take a look at some flowers and their pollinators, and learn about special structures that help them work together perfectly! Performance Expectation: 1-LS1-1. Use materials to design a solution to a human...
