- 3. ENGAGE I Need To Cool Down During a hot and sunny day, it seems that, sitting under a tree is much cooler compared to the surrounding that is exposed to sunlight. Why this phenomenon occur? Explain.

- 8. EMPOWER Discussions Relative Humidity and Temperature 1. What cause the plastic bag to turn cloudy at the end of the experiment? 2. Does the water content in plant influence transpiration rate? 3. What is the relationship between humidity and temperature in this experiment? 4. Why we choose 1 minute as the time interval? 5. What will happen to the leaf when transpiration rate is on maximum? 6. What happen to the transpiration rate when there is high humidity? 7. What happen to the transpiration rate when there is high temperature?
- 9. ENHANCE Why it is not advisable to water the plant during mid- day? Explain this phenomenon.
