In this biology experiment the factors that influence the seed germination are studied by the exclusion method. These include light, moisture, air, heat, and mold. The experiment is an application of the famous biology experiment in which a similar method studies the effects of a plant hormone on plant growth. This is a popular material in Finnish school context and aimed at 7 to 12 years old pupils. Students learn how to make controlled experiments and about the factors that affect the seed germination and which condition(s) offer the most optimal conditions for plant growth. The material helps pupils to understand why agriculture is challenging in Nordic regions. At the baseline sunflower and oats seeds are used in this experiment, but the experiment can be expended to include other kind of seeds to understand the boundary growth conditions for different plant species.
