Biology

Biology is where students watch living systems run: a cell burning fuel, a leaf trading light for sugar. These free interactives let them experiment on life with no prep list, and every one comes with a worksheet, vocabulary cards, and a full NGSS-aligned lesson plan.

Inside the Cell

Zoom into a living animal or plant cell, click every organelle for a real microscope photo, and control the food, water and light that keep it running.
