Explanation:

To solve this fill - in - the - blank problem related to health (a subfield of Natural Science), we analyze the context:

Step 1: Analyze the first blank

The context is about practices to prevent negative health outcomes. The phrase "injury prevention" is a common health - related concept. So the first blank should be filled with "injury prevention".

Step 2: Analyze the second blank

We are looking for a practice related to sun - related health protection. "Sun protection" is a well - known healthy habit to prevent skin - related issues like skin cancer. So the second blank is "sun protection".

Step 3: Analyze the third blank

We need an item that is worn to prevent head injury. A "helmet" is a common item used for this purpose (e.g., in cycling, skateboarding, etc.). So the third blank is "helmet".

Answer:

• First blank: injury prevention
• Second blank: sun protection
• Third blank: helmet
