Why Do Plants Grow Faster in Sunlight Than in Shade?
Research Question
How does the amount of sunlight affect the growth rate of plants?
Explanation
Plants need sunlight to make their own food through a process called photosynthesis. During photosynthesis, plants use sunlight, water, and carbon dioxide to produce energy that helps them grow. When plants receive more sunlight, they can usually produce more energy, leading to faster and healthier growth. In shaded areas, plants may grow more slowly because they receive less light for photosynthesis.
This topic is a good science investigation because you can compare plants placed in different lighting conditions and measure their height, number of leaves, or overall health over time.
