Core Skills Analysis
Science
The student constructed a small greenhouse and monitored the temperature, humidity, and light levels inside it over several weeks. They recorded how these environmental factors affected the germination and growth rate of bean seeds, noting differences between plants inside the greenhouse and those grown outdoors. By measuring soil moisture and observing leaf color, the student identified the roles of photosynthesis, transpiration, and the water cycle in plant development. This hands‑on investigation helped the student understand controlled environments, plant physiology, and the importance of climate variables for agricultural productivity.
Tips
Tips: Have the student design a comparative experiment by adding shade cloths or reflective panels to test light intensity effects, then graph the results. Incorporate a digital weather station to log real‑time data and practice interpreting charts. Invite a local gardener or farmer to discuss how greenhouses are used in sustainable farming, encouraging the student to ask probing questions. Finally, challenge the student to propose modifications that could improve energy efficiency, linking science to engineering design.
