Mathematics, Additional Mathematics, Physics, Chemistry, Biology and Information Technology are not six separate worlds. In every industry they work together. These four projects put you in a real job and show how the topics you are studying connect.
Treat, pump, store, test and bill: the work of a water authority uses every one of your subjects.
Careers: Water treatment plant operator / engineer, Laboratory analyst / chemist, Environmental or public health officer, Hydrologist / civil engineer
Sunshine, cables, bills and batteries: design a solar-plus-grid system for a small island community.
Careers: Power systems / electrical engineer, Solar PV technician / installer, Energy analyst / auditor, Smart grid software developer
A rising number of fever cases: lab results, medicine doses, imaging and patient records all depend on the same six subjects.
Careers: Medical laboratory technologist, Radiographer / sonographer, Pharmacist, Public health officer / epidemiologist
Seeds, soil, sunshine and sensors: plan a farm that grows more food with less waste.
Careers: Agronomist / crop scientist, Agricultural engineer, Soil or food scientist, Precision agriculture technician
These are the topics that appear in more than one subject. Each cell links to the lessons where you will meet the idea.
