Interactive science simulations

Change one variable, observe the result, and try another case. These interactive models make it easier to explore a rule or compare behaviors; they simplify the systems they depict.

For motion, materials, and collective behavior

For circuits, light, and chemical formulas

For patterns from simple rules

Make one change at a time

Try comparing two planets in Gravity Lab, adjusting one flocking rule in Boids, or changing the materials in Particle Playground. Keeping other settings steady makes the difference easier to see.

Treat each model as a learning tool

A playful material or circuit model is not a professional engineering calculation or a laboratory measurement. Read the activity’s explanations and limits before drawing conclusions about a real-world system.
