In How Cold Affects Your Body’s Defenses, host Harith Iskander explains how cold temperatures can impact your body’s ability to fight off infections. When you’re cold, the blood vessels constrict, reducing blood flow to certain areas of the body. This process can weaken the immune system, making it easier for viruses, like the common cold, to take hold. This video is excerpted from BBC’s Got Science?, a science magazine series that explores and explains science in everyday life.
It may only be the size of your fist, but your heart is one of the hardest-working organs in your body. It beats nonstop — whether you’re running laps, laughing with friends, or fast asleep. This Valentine’s season, show your heart a little love by learning what makes it tick.
Think you know what an artery does? Or how long does it take for blood to complete a full circuit through the human body? Get ready for a quiz full of fascinating facts, surprising science, and a few twists that might make your pulse race!
This video playlist brings together 10 fascinating clips from the BBC’s Got Science? series, where everyday questions lead to surprising scientific discoveries. Students explore what’s really happening in the body and brain — from what your brain is doing during sleep paralysis to what it truly means to be “left-brained” or “right-brained.” They’ll investigate what happens when the body becomes dehydrated, how cold temperatures and high altitudes affect how we function, and the unexpected ways our bodies trick us every single day. Packed with “What! Really?” moments, this weird-but-wonderful playlist helps learners connect real science to daily life in unforgettable ways. Get ready to see the familiar become fascinating.
In Patagotitan — The Largest Animal to Walk the Planet, naturalist Steve Backshall explores this seriously huge dinosaur and its massive heart, which measured over 6.5 feet (2 meters) in circumference. Plus, watch an experiment take place to visualize just how powerful the Patagotitan’s heart had to be in order to pump blood throughout its body. This video is excerpted from BBC’s Deadly Dinosaurs, a documentary series in which host Steve Backshall is on the hunt for the deadliest animals to have walked the Earth — dinosaurs — exploring features of several species and putting their abilities to the test to reveal the raw power of these creatures.
