Scientist Lynn Margulis - Fact Sheet, Quiz & Interactive Version (PDF & H5P)

Lynn Margulis – Endosymbiosis and a New View of Evolution
Fact Sheet, Quiz & Interactive Exercises (PDF + H5P) 🧫🔬

This 45-minute resource introduces students in grades 7–10 to Lynn Margulis – a scientist who challenged conventional ideas about evolution and opened up new ways of understanding how complex cells came to be.

Many students are familiar with Darwin and natural selection, but fewer know about Margulis and her theory of endosymbiosis. Through her work in the 1960s and 70s, she proposed that parts of our cells – like mitochondria and chloroplasts – actually originated from ancient symbiotic bacteria. Her ideas weren’t widely accepted at first, but over time they became a foundational part of modern biology.

To make this topic accessible, I’ve put together a compact, ready-to-use lesson with everything needed for a solid introduction. It includes a short informational text, a fact sheet, quiz questions with answers, and a creative partner task. All materials are available in both color and black-and-white versions, plus there’s an H5P version for digital use.

What’s included:

• A student-friendly text about Lynn Margulis and her contributions to evolutionary biology

• A fact sheet to help students collect and structure key points

• Quiz questions with solutions for quick checks or review

• A pair activity where students create and exchange their own questions

• Printable PDF and interactive H5P formats for flexible use 💻

• Answer key included ✅

I’ve used this resource as part of our evolution unit, especially when discussing how scientific theories develop and why some ideas take time to be accepted. It also fits well into lessons on women in science or interdisciplinary approaches to biology. The format allows for independent work, partner activities, or short projects – whatever suits your group best.
