A complete IB Biology osmosis investigation worksheet using an online simulation. Students collect realistic data, identify outliers, calculate % mass change, plot graphs with error bars, and run a statistical test — all in one lesson. No lab equipment required. This 8-page worksheet guides IB Diploma Biology students through a full investigation into how NaCl concentration affects the mass of potato cylinders — using the free Teaching with Tech Osmosis Investigation simulation. Students design

Help your students understand how molecular evidence is used to investigate evolutionary relationships with this engaging online cladogram-building activity. This resource guides students through the process of using real genetic sequence data to compare species, identify evolutionary relationships, and interpret cladograms and phylogenetic trees. Students use an online Cladogram Builder simulation to work through the same core workflow used by researchers: selecting species, retrieving DNA se

Give your students hands-on microscopy skills without the lab. This resource pairs a free interactive light microscope simulator with a structured worksheet that walks students through calibration, measurement, and data analysis — exactly the skills they need for practical exams. Students use the simulator to select slides, adjust objective lenses, focus, pan across specimens, and measure cells using an eyepiece graticule — just like a real microscope. The worksheet guides them through every st

Stop worrying about broken lamps, cold water baths, and temperamental Elodea!This comprehensive worksheet and accompanying free interactive simulation provide the perfect "wet lab" alternative for IBDP Biology students. Designed specifically to prepare students for the Internal Assessment (IA), this activity guides them through experimental design, data collection, and the rigorous statistical analysis required for top marks. ABOUT THE ACTIVITY:Students use a custom-built, browser-based simulati
