Seeds are often sterilised using a solution of hydrogen peroxide (H2O2\text{H}_2\text{O}_2H2O2) before they are germinated on sterile agar. This sterilisation process kills fungal spores and bacterial cells on the seed coat, but if the concentration of hydrogen peroxide is too high, it may damage the embryo and prevent germination.
Design an investigation to find the optimal concentration of hydrogen peroxide to sterilise the seeds while allowing maximum germination.
Your answer should include experimental details and be written in full sentences.
