Discover how light color influences seed germination by testing seeds under various colored lights. Analyze which color promotes the fastest growth.
If seeds are exposed to different colors of light, then those under blue light will germinate faster than seeds under other colors.

Fill planting trays with potting soil.
Plant seeds evenly in each tray.
Set up a light fixture with different colored bulbs over each tray.
Water seeds with the same amount daily.
Observe and record the growth progress daily.
Measure seedling height every two days with a ruler.
Take photos of seedlings every day for visual comparison.
Analyze which light color resulted in the fastest germination and growth.
Compile data and compare with initial hypothesis.
Draw a conclusion based on the results.
Seeds exposed to blue light are expected to germinate faster, as blue light is often linked to photoreceptor activation in plants.
