Ungdomsskolen har de siste uke lært om lys og bruken av linser. Denne dagen var elevene ute og fikk lært om konvekslinse, brennpunkt og brennvidde i den strålende vårsola.
Vi snakket også om faren ved å la glass ligge igjen i naturen og hvordan en i nødstilfeller kan lage bål med hjelp av forstørrelsesglass.
