Outline of stemNRICH

Age 14 to 18 Challenge Level:

stemNRICH consists of 4 applications nodes and 2 mathematics nodes, as shown in the table and diagram below. Although the problems are located in discrete nodes, there is some natural overlap between the various areas, particularly chemistry/biology and physics/engineering.

At a basic level, all problems refer to GCSE level concepts in science and mathematics, although concepts from A-level mathematics and science will be needed in places.

Most problems come equipped with a solution, hint and teachers' notes pages. There is a wide range of activity-types, so you are sure to practise a variety of mathematical skills.
