Survival Rivals: Experiments Inspired by Darwin

Survival Rivals are hands-on experiments inspired by Darwin and produced by the Wellcome Trust.

The three resources in the series are:
* I'm a Worm, Get Me Out of Here (exploring natural selection)
* Brine Date (looking at sexual selection)
* The X-Bacteria (investigating antibiotic resistance in bacteria)

Each resource includes teachers' notes, technicans' notes and guides for students and include everything needed to carry out the experiments in school. All of the experiments are designed to help young people see for themselves how Darwin's ideas link to modern evolutionary principles and contemporary biomedicine.

I'm a Worm Get Me Out of Here

These resources allow students to explore natural selection using different coloured baits (spaghetti ‘worms’) that are selected and eaten by birds. Uneaten ‘worms’ are counted after predation and the ‘worm’ population is replenished in proportion to those colours which remain. After several cycles of predation and ‘...

Brine Date

With this resource, students develop observation skills by investigating the phenomenon of ‘mate-guarding’ in brine shrimp. Following a teacher-led discussion, students generate hypotheses. For example, one of the hypotheses may be that larger females pair with larger males. These may be tested experimentally by...

The X Bacteria

In this practical protocol students investigate one way in which bacteria acquire antibiotic resistance through conjugation - horizontal gene transfer from one bacterial strain or species to another. Plasmid-mediated evolution is fast because whole functional ‘modules’ are lost and gained, rather than the gradual...
