|I have a variety of garden seeds for flowers, fruits, and vegetables. I would like to conduct a science experiment by germinating them. Do you have any suggestions?|
|Here's a few ideas:
1. You could simply compare the length of time it takes for each type of seed to germinate. Be sure all variables are the same--same planting medium and planting depth, same watering schedule, etc. You could then make a chart and see if you can spot any trends. You could try to correlate germination time with the size of the seed.
2. You could compare the germination times for each type of seed in different media. For example, if you have bean seeds, plant 4 pots of beans in soilless seed starting mix, 4 pots in straight sand, 4 posts in peat moss, and 4 pots in vermiculite--or choose other planting media. Chart how long it takes for each to germinate. If you have the time and space, you could continue the experimentand compare growth rates.
3. You could compare the various growth rates using different strengths of fertilizer--for example, plant 16 pots of beans and water 4 with straight water, 4 with a liquid fertilizer solution at 1/4 strength, 4 with full strength, and 4 at double strength, and chart the growth rates.
4. You could compare germination times and growth rates under different types of light (and in the dark).
There are so many more possibilities. You might search our database using the word "experiment" for more ideas. I hope this is helpful.
