The Living World

Biology is the story of living things, and the best way to understand it is to see it move. In this course you will lift the skin off a 3D human body to meet the skeleton and organs, feed sunlight to a leaf and watch it make sugar, follow a butterfly through every stage of its transformation, and pace the heartbeat and breathing of your own body. Every model is built to real proportions, every animation follows real biology — so the wonder you feel here is the wonder of how life actually works.

You will learn: doneMajor body systems: skeleton, organs, muscles doneHow plants make food from sunlight (photosynthesis) doneLife cycles and metamorphosis doneThe heart, lungs and the rhythm of breathing doneThinking like a biologist: observe, compare, explain

Lessons

1 accessibility Human Body Explorer A full-size anatomical human: glass skin over hundreds of real muscles, 206 bones, and organs that beat and breathe. Peel the layers, pick a body system and tap any part to learn what it does. 3D model 14 min done 2 eco Plant Power: Photosynthesis Run the classic pondweed experiment: move a lamp, add CO₂ and change the temperature, then count the oxygen bubbles. Zoom into a leaf and a chloroplast to see where the sugar and oxygen are made. 3D model 13 min done 3 flutter_dash Become a Butterfly Follow a plain tiger butterfly through a whole month on its aak host plant — an egg under a leaf, a caterpillar chewing the leaf edge, a gold-dotted chrysalis and an adult that emerges, dries its wings and flies to a flower. 3D model 12 min done 4 favorite Heart & Lungs A beating heart and breathing lungs sculpted from real anatomy: cut the heart open, follow red blood cells through every chamber and into the lungs, and watch the ECG change as you exercise. 3D model 13 min done
