Lesson 1

The Seed That Slept for 2,000 Years
A seed found in a 2,000-year-old fortress did something scientists thought was impossible — how can a tiny seed do almost nothing for centuries and still not be dead?
StartLesson 2

Buried Alive, Upside Down, and Out of Time: A Seed's Great Escape
A waking seed is buried in total darkness, maybe upside down, with only a small lunchbox of food left — yet its root always finds down and its shoot always finds up. How does a seed with no eyes know which way is which before its food runs out?
StartLesson 3

The Tree That Ate Almost Nothing
A scientist grew a willow tree in a pot for five years and it gained the weight of a grown man — yet the soil in the pot lost barely a spoonful. So what is a tree actually made of?
StartLesson 4

The Tree's Hidden Straws
A tree lifts water higher than a ten-story building every single day — with no heart, no pump, and no mouth to suck. What is doing the lifting?
StartLesson 5

The Tree That Bumped Its Head on the Sky
The tallest tree on Earth is taller than a 30-story building — so why hasn't any tree, in millions of years, ever grown just a little bit taller than that?
StartLesson 6

The Carving That Refused to Climb
A kid carves a heart into a young tree at eye height — twenty years and a whole lot of growing later, where is that carving now?
StartLesson 7

The Trunk That Kept a Secret Diary
A tree's tips only build at the very ends — so what invisible worker fattens the trunk every year, and why does the wood underneath keep a secret diary nobody wrote?
StartLesson 8

The Storm That Pushed Like a Truck
A storm shoves a tree with the force of a truck — so what secret is hiding under the ground, and why do the bendiest trees survive while stiff ones break?
StartLesson 9

Trees That Fight Back
A tree can't run, hide, or swat — so how has it stood its ground against drilling beetles and leaf-munching giraffes for hundreds of years?
StartLesson 10

The Tree That Fires Its Own Factories
Leaves are the tree's precious food factories — so why do maples and oaks deliberately throw away every single one each autumn, and where do those fiery colors suddenly come from?
StartLesson 11

A Seed Drops at the Giant's Feet
Our grown-up tree is ready to make the next generation — but its very first seed just fell straight down to the ground below, and something about that spot is a problem.
StartLesson 12

The Old Giant: How Trees Help the Whole Forest
Scientists dug under the oldest tree in the forest and found its roots covered in white fungus threads — what's really going on down there is the biggest surprise of the whole tree's life.
