Light and Dark on Seed Germination
Easy
Do you want to know how light and dark affect the germination of seeds? Let's find out by setting up two jars with seeds and observing the results.
Hypothesis
The hypothesis is that light and dark will have an effect on seed germination.
Method & Materials
You will mix gelatin, add liquid fertilizer, and place seeds on the gelatin. Then, wrap one jar in aluminum foil and place them side by side in a warm area with indirect sunlight. Check them each day to compare how and when they germinate.
You will need unflavored gelatin, hydrogen peroxide, isopropyl alcohol, liquid house plant food, disinfecting hand soap, household disinfectant, tap water, seeds, clear jars with lids, a measuring cup, forceps or tweezers, a spoon, glass rod, or other stirring instrument, transparent tape, and aluminum foil.
Results
The results showed that seeds germinated in both the light and the dark. The stems in the dark grew the tallest, and the leaves in the light were more green.
Why do this project?
This science project is interesting because it shows how light and dark can affect the germination of seeds.
Also Consider
Experiment variations to consider include using different types of seeds, different amounts of light, and different temperatures.
