Today, we started to review and consolidate work students have already done on Plant Science. To start with the class did a short practical using Potometers and small branches with leaves. They measured the rate of transpiration in different conditions, using a hair dryer at different settings.Factors that affect the rate of transpiration due to the rate of evaporation, in plants are Relative Humidity, temperature and movement of air.
We then discussed lab reports and the class were given their lab report folders and asked to evaluate their lab reports to date and make comments for each one on what they should improve upon.
Finally we started to go over the content of the Plants science topic which we will complete on Wednesday.

Today the class used visking tubing to model one of the activities in the proximal convoluted tubules of the kidney where Glucose is reabsorbed by the body.
