Biology
Plan an experiment to test the hypothesis that acidity affects the germination of a seed.
You need to identify all the varaibles: Independent, dependent and controlled.
You need to have a control group and explain clearly how you control all the variables and make sure that it is a fair test. You need to think about and state clearly the quantities that you would use, for example what volume of acidic solution would you add? How many seeds would you use? etc.
You need to have a good plan so that you can carry out the experiment on Monday.
