Let's evaluate each statement one by one:

1. **When ice cream melts, a chemical change occurs.** - **False** (Melting is a physical change; the composition of the ice cream does not change.)

2. **Acid rain damaging a marble statue is a physical change.** - **False** (This is a chemical change, as the acid reacts with the calcium carbonate in the marble.)

3. **Burning wood is a physical change.** - **False** (Burning is a chemical change; it transforms the wood into different substances.)

4. **Breaking up concrete is a physical change.** - **True** (Breaking concrete changes its form but not its chemical composition.)

5. **Combining hydrogen and oxygen to make water is a physical change.** - **False** (This is a chemical change; it involves a chemical reaction to form a new substance.)

6. **Sand being washed out to sea from the beach is a chemical change.** - **False** (This is a physical change; the sand retains its composition.)

7. **Changing the size and shapes of pieces of wood would be a chemical change.** - **False** (This is a physical change since the wood's chemical composition remains the same.)

8. **Evaporation is a physical change.** - **True** (Evaporation changes the state of the liquid to a gas without altering its chemical composition.)

9. **In a physical change, the makeup of matter is changed.** - **False** (In a physical change, the makeup of the matter remains the same; only the form or appearance changes.)

Overall evaluations:
- **True Statements:** 4, 8
- **False Statements:** 1, 2, 3, 5, 6, 7, 9
