Science (Naturfag)

Interactive 3D pages I made for 8th-grade natural science (naturfag), set along the Helgeland coast in northern Norway. Each one is a single self-contained HTML file: open it in the browser, click around, and do the missions.

All pages are bilingual: use the NO / EN button in the top right corner. They need no server, login or internet connection once loaded, so they also run offline. Best on a laptop or tablet; the files are 1.6–5.3 MB.

Toxin Elevator

Live

Biomagnification as an elevator: each floor of the marine food chain concentrates the toxin (PCB or mercury) further. Adjust emissions and time, ban the substance, and see bioaccumulation inside a single cod. The numbers come from a simplified model. (Norwegian title: Miljøgift-heisen. File size 2.6 MB.)

Energy Chain

Live

All energy in the sea starts with the sun. Follow it from phytoplankton up the chain, see how most of it is lost as heat or goes to decomposers at each step, and look inside the cell at photosynthesis and respiration. (Norwegian title: Energikjeden. File size 4.3 MB.)

Features

  • → Energy flow and the 10 % rule
