Biology Virtual Labs
Interactive biology simulations for Biology. They run in the browser on any device, with no login and no equipment needed, and they work in English and Spanish. The tags on each lab show the concepts it focuses on. Take them, adapt them, and use them in your own room.

Leaf Disk Lab
Float spinach leaf disks in a beaker, change the light color, brightness, temperature and bicarbonate, and find out what controls how fast photosynthesis makes oxygen. Predict first, then explain your evidence.
