1. Ask a QUESTION: What effect does sunlight have on plant growth?
2. Make a HYPOTHESIS: If plants receive more sunlight, then they will grow taller.
3. Test the HYPOTHESIS:
- Supplies: Two identical potted plants, a sunny window, a dark closet, water, measuring tape.
- Procedure: Place one plant in a sunny window and the other in a dark closet. Water both plants equally every day for two weeks. Measure the height of each plant every three days.
4. Record the RESULTS: After two weeks, the plant in the sunny window grew to 15 cm, while the plant in the dark closet grew to 5 cm.
5. Draw a CONCLUSION: The plant that received more sunlight grew significantly taller than the plant in the dark, supporting the hypothesis that sunlight positively affects plant growth.
