Fysik

Vad är ljud? Kan man höra något i rymden? Varför låter olika instrument olika? 



 använda kunskaper i fysik för att granska information, kommunicera och ta ställning i frågor som rör energi, teknik, miljö och samhälle, 

 genomföra systematiska undersökningar i fysik, och 

 använda fysikens begrepp, modeller och teorier för att beskriva och förklara fysikaliska samband i naturen och samhället. 

 Hur ljud uppstår, breder ut sig och kan registreras på olika sätt. Ljudets egenskaper och ljudmiljöns påverkan på hälsan. 

 Historiska och nutida upptäckter inom fysikområdet och hur de har formats av och format världsbilder. Upptäckternas betydelse för teknik, miljö, samhälle och människors levnadsvillkor. 

 Systematiska undersökningar och hur simuleringar kan användas som stöd vid modellering. Formulering av enkla frågeställningar, planering, utförande och utvärdering.

 Sambandet mellan fysikaliska undersökningar och utvecklingen av begrepp, modeller och teorier. 

Dokumentation av undersökningar med tabeller, diagram, bilder och skriftliga rapporter, såväl med som utan digitala verktyg.
