This video demonstrates population sampling techniques by investigating whether the number of buttercups in our chosen field differs from the top of the hill to the bottom.

These resources from the Wellcome Trust look at how populations grow, change and move, and why understanding them is so important. The resources use real research to illustrate many aspects of the study of populations, including:

• ecology
• epidemiology
• ...

Portia works with other scientists and engineers to work on systems that will go into space.  She explains how she is working on a project to build a robotic arm to work on samples from Mars.  Portia studied Physics and then Space Engineering at university.
