Growing things yourself is a good way to learn more about the way in which plants function and develop. The following is an example.

• Place oat and radish seeds in pots filled with soil.
• Mark the pots so that you know what seeds have been planted in them. Make note of the number of seeds you have planted.
• Use the information in the bags of seeds to determine how deep in the soil the seeds should be planted. Oat seeds are often planted approximately one centimeter deep in the soil, whereas the planting depth of radish seeds can vary.
• Cover the seeds with soil.
• Leave the pots in room temperature, in a place that gets plenty of sunlight (e.g. near a window).
• Make sure that the soil is wet throughout the cultivation period. You can prevent moisture from evaporating by placing translucent pieces of plastic on top of the pots.
• Observe the growth of the seedlings. How are they different?
