3. Soil pH
Rhubarb
Cranberries A B C
Geranium

4. What do I know? Cranberries grow best in ACIDIC conditions
Rhubarb grows best in NEUTRAL conditions
Purple Germaniums grow best in ALKALINE conditions

5. Experiment- Page 4 Apparatus 2 x beakers Universal indicator
3 x filter paper
Funnel
Instructions
Add 50 mls of water into a beaker
Add one spatula of soil A into the water and stir
Filter the sample into the other beaker
