Aim	To determine the conditions for seed germination
Problem Statement	What conditions are needed for a seed to germinate?
Variables	A seed will germinate only if there is water, air and suitable temperature (warmth)
Materials	Seeds, oil, cotton, cooled boiled water, labeling paper
Apparatus	Test tube, refrigerator, test tube rack
Procedure	Four test tubes labeled A, B, C and D were prepared with their contents as shown in diagram above. Test tubes A, B and C were placed in the laboratory, and test tube D was placed in the refrigerator. The seeds were observed after 2 days.
Results	Test tube Presence of Germination of seeds Water Air Warmth A √ √ √ Germinate B X √ √ Does not germinate C √ X √ Does not germinate D √ √ X Does not germinate                                         A germinated seed
Discussion	From the experiment above, seeds only in the presence of water, air and suitable temperature (warmth).  He seed will not germinate even though only one of the above factors is absent.
Conclusion	Hypothesis is accepted. A seed will germinate only if there is water, air and suitable temperature (warmth).
