Learning about photosynthesis

Sylvester has been helping Year 9 investigate photosynthesis. Elly, Lexi and Niamh tested a leaf that had been kept in the dark. They made sure that they turned the Bunsen burner off before they used ethanol to remove the chlorophyll. Sylvester doesn’t think there’s any starch in the leaf because iodine goes blue/black if starch is present.
