The Light of Life

Project by group rhsnicefall2019

Explore Vegetables usually require six to eight hours of sunlight a day. It also promotes vitamin D, which is a critical nutrient. Blue light helps plants with chlorophyll production. Red light helps with photosynthesis and plant growth.
Research Question What is the best light to help with germination and plant growth?
Predictions I believe that natural sunlight is always the best for the plant as that is how they began to thrive on land. But also I think once the seed germinates the red light will promote more growth.
Experimental Design We will test three different plants with three seeds of each. Using an seed starter (small pot) and soil we will measure in inches and days. We will be testing sunlight, red and blue light. Each will have an equal amount of light for 12 hours a day. The lightd have timers to turn off at dusk and on at dawn. The three seeds we will be testing are radishes, peas, and nasturtium.
Conclusion Overall the red light was great for germinating and grow first and long, but the sunlight helped the stems stand up strong, the blue was the in-between.
