Answer: To start seeds, use a clean soilless potting mix. Dampen it slightly so it is moist like a wrung out sponge. Fill a very clean small pot with the mix. Sprinkle the seeds on top of the mix, sprinkle with a very light layer of mix to barely cover, press gently, spritz with water to settle the soil. Cover the pot with clear plastic wrap and hold that in place with a rubber band. Label the pot with plant name and date. Set the pot in a location out of direct sun and with average room temperature of about 70 to 75 degrees. You should see no more than a very light misting of moisture on the cover. (If there is too much condensation, the seeds will rot.) Check daily for sprouting. Once the seeds sprout, immediately remove the cover and place in a very bright location. Usually, it is necessary to use supplemental lights for the best results. Keep the soil lightly moist but not sopping wet. That is how to start the seeds.
For designing your experiment, I would suggest you discuss developing your hypothesis and possible ways of testing it with your teacher. Good luck with your project.
