INSTRUCTIONAL UNIT ON THE THEME NITROGEN

The instructional unit is directed at students of the upper levels in a high school, since the topic of sustainability and environment are better suited to a higher level.

The unit comprises two double classroom periods of 90 minutes each. In the first double classroom period an extensive basic knowledge is imparted, which the second double period builds upon.  In the latter the students should make a more exact picture of the nitrogen problematic through practical work, discussions and a worksheet.
