Tasks (T) and questions (Q) for each lesson:
Arbejdsspørgsmålene (Q) kan findes på et separat arbejdsark som kan udleveres til eleverne i undervisningen:
T1: make more watermolecules.
Q1: why are the watermolecules shaped as a triangle? Write your answers on the worksheet.
T2: make potassium ions. Think long and hard about the shape and color that you chose. And where topical the potassium-ions in the model.
When you’re finished creating the watermolecules and potassium-ions, you should save the model as: pi1X.nlogo and upload it to the conference. Make “x” something you can remember (groupnumber, name …). Chose somebody elses .nlogo-file and answer Q2.
Q2: why did (another group) chose this particular shape and color to represent the potassium-ions? Write your answers on the worksheet.
T3: hit “go” and observe what happens in the simulation. In particular look at the “plot” and observe what happens.
Q3: which of the two compounds; watermolecules or sodiumions, reach equilibrium first? Why is that? Write your answers on the worksheet.
T4: hit “go” and
Q4:
T5: hit "Go-Once" and observe what happens in the simulation.
Q5: What is the function of the botton “Go-Once” and why is it in the simulation? Write your answers on the worksheet.
