Learning Intention To test the pH of different soil samples To identify the plant which grows BEST in each sample

Soil pH Rhubarb Cranberries A B C Geranium

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

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 Add universal indicator and record results Decide which plant would grow best in the sample Repeat for sample B and C

Conclusion Soil Sample Colour pH Acid/Alkali/Neutral Plant which grows best A B C

Conclusion Soil Sample Colour pH Acid/Alkali/Neutral Plant which grows best A Greeny/blue 8 Alkali Purple Germanium B Green 7 Neutral Rhubarb C Yellow/Orange 3 Acid Cranberries
