Here are the solutions to your questions based on the provided data: Part 5: Draw Conclusions 1. Analyze the Data: Which light condition produced the tallest plants? Based on the average height in Week 3, the High Light condition produced the tallest plants. High Light* Which light condition produced the shortest plants (or no growth)? Based on the average height in Week 3, the No Light condition produced the shortest plants (no growth). No Light* What did you notice about the colour and health of the plants in the "No Light" group compared to the others? The plants in the No Light group were brown and not healthy, while the plants in the High Light group were green and healthy, and the plants in the Medium Light group were yellow. 2. Conclusion Statement: Was your hypothesis supported by the data? ✅ YES* Explain your answer. Use your data as evidence. My hypothesis (that plants grow better with more light) was supported because the plants in the High Light group had an average height of 20 cm by Week 3 and were green and healthy. In contrast, the plants in the Medium Light group only reached 10 cm and were yellow, and the plants in the No Light group showed no growth (0 cm) and were brown and not healthy. This demonstrates that light is crucial for plant growth and health. Part 6: Communicate Findings & Reflection 5. Reflection: What is one source of error in your experiment? What would you do differently if you did this experiment again to make it better? Source of Error: The temperature might have been slightly different for different plant groups (e.g., in the cupboard for the "No Light" group). Improvement: To make it better, ensure all plants are kept at a consistent and controlled temperature* throughout the experiment. This could be achieved by using a growth chamber or by carefully selecting a location where temperature variations are minimal and uniform for all experimental groups.
