Germination

• Aim : observe geotropism in roots or phototropism in shoots of plants
• step 1: put cotton wool into 3 petri dishes and add the same volume of water to each dish
• step 2: add 10 seeds to each dish and place them in a warm place where they wont be disturbed
• step 3: allow the seeds to germinate and add more water if the cotton wool dries out
• step 4: Once the seeds have germinated, ensure the petri dishes each contain the same number of seeds, and remove any extra seeds if necessary.
• step 5: One petri dish will sit in full light on a windowsill, the second will be in a dark cupboard, and the final dish will be placed in partial light.
• step 6: every day for a week, erasure the height of each seedling and record the results in a table, you must record the height of the individual seedlings on each day
• step 7: calculate the mean height of the seedlings each day and compare the mean heights in 3 different locations
