Explanation:
**1. Where are bacteria found?**
Bacteria can be found in various environments, and their presence is not limited to a specific location. Common places where bacteria are found include soil, water, air, on surfaces, and in and on living organisms.
**Procedure:**
1. **Labeling Agar Plates:**
- Label one agar plate as "control" and the other as "exposed."
2. **Exposure:**
- Tape closed the cover of the control plate.
- Remove the cover of the exposed plate and leave both plates on the table for 5 minutes. Avoid touching or breathing on the agar.
3. **Incubation:**
- Tape close the lid of the exposed plate after 5 minutes.
- Store both plates upside down in a warm place.
4. **Observation:**
- After 2 days, record the number of bacterial colonies on each plate.
**Analyze and Conclude:**
1. **Observation:**
- Determine which plate had more colonies.
2. **Conclusion:**
- Explain the source of bacteria on the plates. Discuss whether exposure influenced bacterial growth.
3. **Questions for Further Investigation:**
- a. What types of bacteria are present on the plates?
- b. How does temperature affect bacterial growth?
- c. Does the location (indoor vs. outdoor) influence bacterial colonization?
Note: These questions aim to extend the investigation and explore different aspects of bacterial behavior and growth.
