In addition to the procedure in the post below, here are some notes:
Add 2.5g of Sodium Bicarbonate (not 3cm)
The independent variable you decided on is to vary the concentration of sodium bicarbonate in solution:
2% (0.15g)
4%
6%
8%
1%
To ensure the 'freshness' of the leaves, we will use ivy from the wall behind the science labs.
