🧪 Part 2: Understanding Decomposition

4. What is decomposition? (Use your own words)

5. Which of these are signs that decomposition has occurred? (Tick all that apply)

Browning or darkening

New smells appearing

Softening or hardening

Steam or smoke

No changes at all

6. Explain how heat caused decomposition in your food sample:

🍽️ Part 3: Food Preservation Connections

7. How might controlled heating help preserve food? Give two examples:

Example 1: _________________________________________________

Example 2: _________________________________________________

8. True or False: Heat always destroys food and makes it inedible.

True

False

Explain your answer: ________________________________________

9. Extension Challenge: Predict what would happen if you heated your food sample for 15 minutes instead of 8 minutes. Explain your reasoning:

10. Reflection: Describe one thing you learned about how heat affects food and how this connects to food preservation:
