B. It is a cumulative evaluation
C. It is carried out once in a year
D. It is carried out throughout the year

Answer

To determine which statement is incorrect regarding continuous and complete evaluation (CCE) in the teaching of science, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Continuous and Complete Evaluation (CCE)**:
- CCE is an educational assessment system that evaluates students continuously throughout the academic year rather than relying solely on a single examination at the end of the year.

2. **Analyzing the Options**:
- **Option A: Constructive Evaluation**:
- This refers to an evaluation that encourages learning through practical activities and experiences. This is a characteristic of CCE, so this statement is correct.

- **Option B: Cumulative Evaluation**:
- Cumulative evaluation means that the assessment takes into account the cumulative knowledge and skills acquired over time. This is also a characteristic of CCE, making this statement correct.

- **Option C: Carried out once in a year**:
- This statement suggests that evaluation occurs only once a year. This contradicts the concept of CCE, which emphasizes continuous assessment throughout the year. Therefore, this statement is incorrect.

- **Option D: Carried out throughout the year**:
- This aligns with the principles of CCE, as it indicates that evaluation is ongoing and not limited to a single event. Thus, this statement is correct.

3. **Conclusion**:
- The incorrect statement regarding continuous and complete evaluation in the teaching of science is **Option C: Carried out once in a year**.

### Final Answer:
**Option C is incorrect.**
