Elina can conduct an experiment with varying sunlight exposure on plants to observe the impact on growth and health.
To study the requirements of sunlight for green plants, Elina can conduct an experiment using different levels of sunlight exposure on identical plant specimens. She would need to set up multiple groups of plants: one receiving full sunlight, one in partial shade, and one in complete darkness.
Elina should then observe and record the growth, color, and overall health of the plants over a specific period. By comparing the results from each group, she can analyze how sunlight impacts plant growth and formulate conclusions based on her observations.
Results should include data on plant height, leaf size, and overall vitality to determine the optimal amount of sunlight green plants need for healthy growth and photosynthesis.
