Microwaves are a form of electromagnetic radiation and they penetrate into human tissue. There is still a significant debate about the safety of holding even a low power microwave transmitter next to your brain or keeping it in a trouser pocket. The possibility of...

The cell is the smallest unit of life and for many millennia single celled organisms were the only form of life on Earth. It’s this type of life that astrobiologists are looking for elsewhere in the solar system. In this activity, wallpaper paste is used to build model cells Curriculum areas covered: • Cell biology...

Produced by the Charles Darwin Trust, these resources allow students to consider some of Darwin's studies on bees and other social insects. Through this context, students are able to develop their skills of scientific enquiry, observation, data analysis and communication.

The activities allow students to:...

Produced by the Charles Darwin Trust, the activities in these materials help students to consider biodiversity within a habitat. To observe change over time, in 1846 Darwin planted a hedge at Down House. Twenty years later, he surveyed the hedge and recorded those species that had disappeared and new plant arrivals...

This resource includes a suite of games designed to promote thinking, learning and understanding as well as being enjoyable and engaging. They are all based around molecules that play key roles in life on Earth.
