More About Solar System for Kids: Lexi
Lexi is a solar system and gravity playground made for little hands, ages 3 and up.
DROP IT AND SEE
In the Gravity Lab, children drop eggs, balls, feathers, friendly animals, water and sand, then switch the world. On the Moon things fall slowly, on Jupiter they fall fast, and with gravity off everything floats. The physics is real: the egg that cracks when it falls off the shelf on Earth lands safely on the Moon, and the speed meter shows why. Animals are never hurt: they land softly and smile.
SEVEN SPACE STUDIOS
• Gravity Lab: the Drop Zone and mini games: Moon Bounce, Egg Drop Challenge, Balloon Lift, Rocket Launch, Catch the Stars, Stack It and a gravity marble run.
• Solar System: fly to the Sun, the planets and the Moon in 3D, hear friendly facts, then jump into the Gravity Lab on that world.
• Space Coloring: paint a rocket, an astronaut, planets, a Moon rover and more in 3D.
• Space Puzzles: planet puzzles, planet order, size sorting and constellations.
• Star Studio: paint the night sky with glowing brushes, spin galaxies and stamp planets.
• Space Learning: a Space ABC, counting stars, gravity words, tracing and a "Which falls first?" quiz.
• Space Music: a planet band, a star xylophone, Moon drums and space sounds.
MADE FOR CHILDREN AND THEIR GROWN-UPS
• A warm read-aloud voice, captions and big buttons.
• Works fully offline. No ads, no tracking, no accounts: nothing leaves the device.
• English, Arabic, French and Persian.
• Purchases and settings sit behind a grown-up check.
Some activities are open to everyone; a membership unlocks all of them.
