Learning you can interact with.

Focused science models for classroom investigation. Change one variable, watch what happens, and connect the pattern to the biology.

Designed for learning

Small tools, clear purpose.

Experiment freely

Pause, reset, and compare settings without signing in.

Interpret thoughtfully

Each activity states what its model simplifies, so an animation is not mistaken for literal molecular behavior.

Private by default

No trackers, advertising, external fonts, or third-party runtime scripts.
