All guides- Interactive Simulations in the Classroom: 10 Engaging IdeasHow to use interactive simulations in the classroom: projector demos, self-paced links, group work, homework and checks, with ideas for science and math.
- How to Embed a Simulation in Your LMSHow to embed a simulation in your LMS: when to use a link, embed code or QR code, what the iframe does, steps for nine platforms and fixes for blank frames.
- Predict–Observe–Explain with SimulationsPredict–observe–explain with simulations: lock in predictions, run the experiment, discuss the gap. A full worked example, prompts and discussion moves.
- Using Simulations for Formative AssessmentUse simulations for formative assessment: question sets on a link, predictions, number answers with tolerance, class results and 8 ready-to-copy questions.
- Free Online Science Labs for Middle and High SchoolFree online science labs for middle and high school: 28 virtual labs in physics, chemistry, biology and earth science, what students do and the lesson plans.
- How to Create a Simulation for Your Lesson with AICreate a simulation with AI for your lesson: write a clear description, pick a level, edit by chat, check the science, then share it with your class.
Create your own interactive simulations
Describe your lesson in plain words and AI builds a working simulation for you, in your language. Or remix any simulation in the library to fit your class.
- Create from a description of your lesson
- Remix any simulation: change the numbers, context or labels
- Share it with your students like any other simulation
