Ideas belong together.
Explore a question across different worlds.

How do we know?
Separate a pattern, a prediction and a cause. Change an assumption, keep every result, and inspect the evidence behind a conclusion.
Start exploring
From silicon to a decision
Follow charge, a changing logic level and the information carried by connected circuits.
Start exploring
From heat to electricity
Follow energy across a wall, through moving machinery and into an electrical circuit. Keep matter, energy and accounting boundaries separate.
Start exploring
Structures that carry us
Move a load, find the supporting force and follow its path through a bridge, a lever and a body.
Start exploring
Matter under the magnifier
Move from atom identity and probability to molecular machinery and familiar materials. Keep each scale and model in view.
Start exploring
Messages inside cells
Explore a molecular machine, follow a short message and connect amino-acid chains to living systems.
Start exploring
From light to motion
Collect energy from light, store it chemically, carry it through a circuit and turn it into motion.
Start exploring
How you sense the world
Follow light and vibration into the body. Separate the physical signal from the work of sensing and perception.
Start exploring
Open up the everyday
Look inside a familiar device, trace what moves, and connect the working parts to the science.

Eleven new ways to wonder
Turn an engine. Load a boat. Build a bit. Follow a meal. Eleven distinct experiments, each with its own questions, sources and home activity.
Start exploring
Make it move
Start with a turn or a pull. Connect gears, engine timing, crane rigging and the surprising forces inside an arm.
Start exploring
A living world, connected
Follow carbon from a leaf into a meal, then connect digestion, circulation, breathing and sensing.
Start exploring
The invisible engineering of everyday life
Make heat, logic and electrical work visible. Explore why a cold room has a warm side and what insulation actually changes.
Start exploring
Earth, sky and deep time
Change your viewpoint of the Moon, read a moving seafloor, follow water, and find the displacement that holds a boat up.
Start exploringInside everyday wonders
Follow charge, light, blood, water and information through the first collection of everyday experiments.
Start exploring
The body, connected
Trace the connections between a meal, circulation, breathing, movement and hearing.
Start exploringSmall actions. Surprising effects.
Brake a car. Turn a gear. Squeeze a lever. Trace an action through connected parts.
