Kort beskrivelse af undervisningsforløbet

Hvad er statisk elektricitet, elektromagnetisme og elektrisk strøm?

Eleverne skal konstruere deres eget elektriske kredsløb på et sømbræt. Eleverne øver loddeteknik, når de skal fastmontere de forskellige komponenter i kredsløbet. I kredsløbet indgår en figur i kobber efter eget design, hvorpå der skal monteres lysdioder. Undervejs holdes der foredrag om elektricitetens historie og hvilken betydning elektricitet har for vores moderne samfund. Derudover laves der eksperimenter med statisk elektricitet, jævnstrøm, vekselstrøm, elektromagnetisme og induktion.

De færdige elektriske kredsløb må eleverne tage med hjem.

Læringsmål

Eleverne får en grundlæggende viden om elektrisk strøm.
Eleverne lærer at lodde.
Eleverne får indsigt i et stykke relevant teknologihistorie.
Eleverne arbejder kreativt med naturfag.
