🧫 New — Practical Lab
Real experiments with complete worked lab reports: extract DNA from a strawberry, measure photosynthesis with floating leaf disks, and find the concentration of potato tissue by osmosis — each written the IB way, with research questions, variables, example data, conclusions, and evaluations. Open the Practical Lab →
🔬 New — More Virtual Labs
Four interactive simulators: watch a red blood cell swell or shrivel with tonicity, hunt the limiting factor in photosynthesis, feel how temperature speeds diffusion, and bend the Michaelis–Menten curve with enzyme inhibitors. Open the Virtual Labs →
