The Correlation. Correlation is a measue of how close the line fits the points that you found in your experiment. Anyone can say whether they think the line is a good fit or not, but to measure it exactly, we use the correlation coefficient: R2.
As the seasons change and the amount of sunlight decreases, less chlorophyll is produced, and the leaves appear less green. Chlorophyll is broken down into simpler compounds at a constant rate, so green leaf color will gradually fade as chlorophyll production slows or stops.
We spend a lot of time outdoors. We especially enjoy the crisp air and vibrant colors of autumn. For our school science project, we decided to explore the many different leaf colors we notice in the fall and find out what makes these leaves change from green to brilliant orange, yellow and red.e especially enjoy the crisp air and vibrant colors of autumn.
