📋 For Teachers
These simulations are built for the classroom — no login required, no ads, no cost. Here's how to get the most out of them:
- Student Tasks: Select simulations have a full NGSS task packet (pre-screener, investigation, and post-screener). Look for the task badge on individual simulation pages or browse simulations with tasks below.
- NGSS Alignment: Every simulation is tagged with its primary performance expectation. Use the simulation search to filter by NGSS standard.
- Works on Chromebooks: All simulations run in the browser — no downloads, plugins, or app installs needed.
Simulations with complete student tasks: Antibiotic Resistance | Crop Evolution | Big Bang Evidence | Ice-Albedo Feedback | Ideal Gas Law | Gay-Lussac's Law and more.
