Sciencity
How the World Works
Free · Designed for iPad. Not verified for macOS.
Five hands-on journeys: follow electricity, water, rain and gas to your home, and build a house. Offline, no ads, nothing collected.
Where does the light in your room come from? What happens to water after it goes down the drain? Why does it rain?
Sciencity turns the everyday world into a living picture your child can poke, change and even break, so they can see how things really work.
FIVE JOURNEYS, STOP BY STOP
• How electricity gets to your house: make power with a dam, a coal and gas plant, a nuclear plant, a wind turbine or the sun, then follow it through the generator, the step-up transformer, the power lines and the substation to your light switch.
• Water to your tap: collect water from a lake, a well, the sea or a rain tank, clean it, pump it into the water tower and send it through the pipes to your home and back out to the river.
• The water cycle: watch the sun lift water from the ocean, forests, lakes and ice into clouds, then bring it back as rain and snow.
• Natural gas to your home: follow gas from deep underground, a ship or a farm digester through processing, compressors and the city gate to your stove.
• Building a home: pour the foundation, then add the frame, the walls, the roof and the windows, and move the family in.
CHANGE THINGS AND SEE WHAT HAPPENS
Every stop has something to try. Open the dam gate, start a storm on the power lines, burst a water pipe, take the dust out of the air or leave the steel out of the foundation, and watch the whole scene react.
MISSIONS AND A QUICK QUIZ
Each journey has missions to collect ("Find a rainbow", "Run the light, fan and TV at once") and ends with a short quiz.
