Map earthquake shockwaves and measure arrival times on your lab seismograph graph.
Molecule Maker: Snap the Atoms
Grab colorful atoms and snap them together like 3D magnetic blocks! Build water molecules, bubbles, and discover cool chemical reactions where nothing gets lost.
Count your starting atoms before and after snapping water molecules to make sure zero atoms vanish.
River Quest: Rain & Water Cycle
Make it rain over snowy mountain peaks! Watch water flow into rushing streams, carve out river canyons, fill underground wells, and irrigate farm crops.
Trace a water drop journey from cloud to river to underground well in your field notebook.
Creature Traits: Secret DNA Code
Mix animal traits and discover secret DNA codes! Will the baby creatures have spotted fur, floppy ears, or blue feathers? Predict the surprises using trait boxes.
Fill in trait prediction grids in your notebook to guess the baby creature fur patterns.
Heat Flow: Fire & Ice Chamber
Experiment with hot and cold! Test cozy materials like wool and foil, watch warm air swirl upward, and design the ultimate thermos flask to keep hot cocoa steaming.
Record temperature cooling curves in your lab book comparing bare cups vs insulated flasks.
Virus Tag: Stop the Outbreak
Help townspeople stay safe from a friendly tag-chain cold! Test handwashing, cozy masks, and doctor shields to flatten the bug curve and protect everyone.
Graph how fast washing hands stops the spread across 20 neighborhood houses.
Laser Maze: Rainbow Light Lab
Bounce laser beams off shiny mirrors and bend light through glass prisms! Create bright rainbows, aim lasers through tricky obstacle mazes, and zoom in with lenses.
Trace laser angles with a protractor in your journal to navigate the glass maze.
Beak Island: Survival of the Birds
Visit a tropical bird island! When rain changes the trees from small berries to big tough nuts, watch bird beaks naturally adapt over generations to crack the snacks.
Measure and sketch bird beak sizes before and after island drought seasons in your notebook.
Mushroom World: Forest Recyclers
Shrink down into the forest floor! Grow glowing mushroom root webs and friendly earthworms to munch on fallen leaves and turn them into rich, dark garden soil.
Draw the forest underground recycling loop from fallen brown leaves back into green sprout food.
Clean Energy: Wind & Solar Town
Power an entire town with clean energy! Spin giant white wind turbines, catch bright sunshine with solar panels, and store extra battery power for cloudy days.
Calculate how many giant batteries your town needs to keep lights on through a stormy night.
Storm Chaser: Clouds & Lightning
Crash icy arctic winds into warm summer air! Watch fluffy white clouds turn dark, trigger booming thunder and lightning, and predict where storms will travel.
Draw storm symbols on your weather map to predict which town will get rain tomorrow.
Deep Ocean: The Giant Sea Current
Drive the giant underwater ocean conveyor belt! Freeze salty arctic ice, send cold deep-sea water racing across the globe, and see how warm currents warm up land.
Color-code warm surface currents (red) and deep icy currents (blue) on your world ocean map.
Bridge Builder: Heavy Train Test
Build strong bridges across deep canyon gorges! Connect steel beams into sturdy triangles, add suspension cables, and test your bridge with a heavy roaring freight train!
Color-code push beams and pull cables on your bridge blueprint before running the train test.
Sunlight Factory: How Leaves Make Food
Zoom inside a tiny green leaf cell! Catch golden sunbeams with chlorophyll solar panels, split water drops, release fresh oxygen, and brew sweet plant food.
Trace sunshine and water entering a leaf and track the bubbles of clean oxygen escaping.
Why Dual-Format Simulations Outperform Screen-Only Games
Passive tablet games stimulate dopamine without reflection. Praxos connects every 3D simulation run to physical paper journals, requiring children to hypothesize before touching sliders and reflect offline.
Pre-Run Hypothesis
Children write predictions and baseline hypotheses in their physical lab journal before starting the 3D simulation clock.
Deterministic Engine
1 tick = 1 day. Controlled parameter experiments without chaotic noise enable true scientific reproducibility and data logging.
Post-Test Reflection
Kids graph population curves, analyze system collapses, and complete synthesis sketches away from digital screens.
