Sheena Iyengar studies how we make choices -- and how we feel about the choices we make. At TEDGlobal, she talks about both trivial choices (Coke v. Pepsi) and profound ones, and shares her groundbreaking research that has uncovered some...

Pregnancy is quite a feat. The embryo manages to develop, get food, and get rid of their waste, all while staying under the radar of their parent’s immune system.

Bees and flowers are as classic a pair as peanut butter and jelly. But recent research suggests there's a third, much tinier partner in this relationship!

Join the Amoeba Sisters in their updated plant structure and adaptations video as they discuss the terms vascular vs nonvascular and how they relate to plants before exploring some general categories of plants (bryophytes, seedless...

Paul Andersen starts with a brief description of diffusion and osmosis. He then describes the diffusion demonstration and how molecules move over time. He then explains the concepts behind the osmosis lab and how potatoes are affected...

Mr. Andersen gives a brief description of osmosis. He explains how water moves from a hypotonic to a hypertonic solution across a semipermeable membrane. The video ends with a time-lapse demon in class.

No matter how full you are, it seems you can find room for dessert. It’s not your imagination, and once you understand why, you’ll see how you can use this weird quirk of your appetite to your advantage!

Conventional wisdom about diets, including government health recommendations, seems to change all the time. And yet ads routinely come out claiming to have THE answer about what we should eat. So how do we distinguish what's actually...

Paul Andersen explains how organisms regulate their internal osmolarity or not. He starts with a brief description of osmosis and why it is important for animal cell to be surrounded by an isotonic solution. He then explains how...

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.

Paul Andersen explains how pigments can be separated using chromatography. He shows how you can calculate the Rf value for each pigment. He then explains how you can measure the rate of photosynthesis using leaf chads and water...
