Simulations
Interactive, watermarked physics demonstrations — pick one to adjust its parameters and run it.
Enzyme Activity
FREEDial up temperature, pH, substrate, and enzyme concentration and watch reaction rate rise and fall — matches the school experiment on how temperature and pH affect enzymes, with a real Michaelis-Menten curve and a reaction-progress colour change.

ORBITDial up starting population, growth rate, carrying capacity, and a harvesting/predation rate and watch a population trace the classic S-shaped curve toward its habitat's limit — or, if harvesting outpaces growth, decline toward extinction. Traced against an uncapped exponential comparison.
