A student conducted a scientific experiment with a plant. She cut out three 1-inch circles from construction paper and attached each circle to a different leaf of the plant. Finally, she set the plant in front of a sunny window with good air flow and left it there. She made sure that the plant was given enough water during her experiment. After 2 days, she removed one of the circles; after 4 days, she removed another circle; and at the end of the week, she removed the last circle.
Here are her results
The student observed that the plant grew differently in each section where the circles were removed. After 2 days, the section where the circle was removed showed slower growth compared to the other sections. After 4 days, the section with the second removed circle also showed slower growth. Finally, at the end of the week, the section with the last removed circle showed the slowest growth compared to the other sections.
Based on these results, the student concluded that the presence of the construction paper circles affected the plant's growth. The circles may have blocked sunlight or airflow, causing slower growth in those sections. She also noted the importance of sunlight, air flow, and water for the plant's overall health and growth.
