Cellemembran - Evaluering

Evaluering:

Følgende materiale er til rådighed ved evalueringen:

worksheets (fra eleverne)

.nlogo-files (fra eleverne)

Følgende spørgsmål kan tjene som inspiration til evaluering af elevernes udbytte af forløbet:

Hvert spørgsmål er forbundet til "Opgave" (O) og "Spørgsmål" (S) som beskrevet under afsnittet "Arbejdsopgaver":

A1: Do students understand the representations of watermolecules (do they use chemical properties in their argumentations)?

A2: Do the students chose appropiate representations of potassium-ions (do they use chemical properties)?

A3: do the students use their knowledge of homeostasis, and how osmosis and passive diffusion works? Do they know about ioncanals and hence the lack of equlibrium when it comes to sodiumions?

A4:

A5: Do the students identify the correct function of the botton “Go-Once” and do they grasp the idea that the botton gives them the ability to identify the mechanism of how sodiumions bond to the transportproteins and are transported into the internal of the cell through the cellmembrane?
