The TEEP Cycle
Year: 8 Module: Biology Lesson : 14
Prepare for Learning ‘Is light needed for photosynthesis?’ activity. As students enter the classroom, the
worksheets for this activity should be on their desks. Explain that diagrams A and
B show a leaf before and at the end of a photosynthesis experiment. The
experiment was carried out as follows:
A leaf on a shrub was partially covered with aluminium foil
The leaf was leaf was leaf to photosynthesise for two days
It was then placed in iodine solution
Some parts of the leaf turned blue-black in colour.
The students need to shade in the parts of the leaf in diagram B which would blue-
black, and then explain the reasons for this. The worksheets for this can be found
in drawers. (Badger starter activity - Year 9, 29).
