Aim:

To test which condition (external or internal) best suits the growth of seed germination

Hypothesis:

I would assume that the seeds that were placed outside in their natural environment would have a better growth pattern than that of the internally grown one due to the fact that its exposure to nature's day/night length, natural sunlight rain and temperature are the necessary elements for successful seed germination.

Apparatus:

4 Containers (preferably 0mm x 200mm x 100mm)

Small bag of potting mix

Packet of pea seeds

Ruler for measuring seed growth

Watering can

Method:

(1) Pour potting mix into two exact size containers (filling ¾ of the container)

(2) Place four seeds (25mm deep) in each corner of the containers

(3) Place one container outside in full sunlight and one indoors with no sunlight

(4) Water plants once a day

(5) Record results everyday

(6) After two weeks repeat test to ensure that the results have not altered and to limit any substantial variations in the important elements (e.g. light, temperature and rain) that may cause a different result

Variables:

Dependant variable: Growth of seed

Independent variable: Environment (internal/external)

Controlled variables: Type of seed, size of container, type of container, amount of soil, type of soil, amount of water given to the plant
