What's the Difference?
Due to the isolation of seamounts, their biodiversity offers a great deal of information on the development of biological and physical processes. Pupils use simple cluster analysis to rate the similarity and differences in biological...
Curated OER
Perceived Risks
Students rank a list of everyday risks to compare with classmates. They rate each risk on both its ability to be controlled and its observability in the environment. Results are graphed.
