Educational worksheet teaching children about construction worker safety gear and its importance.

Explanation:
Let’s go through each question one by one, using the labels in the diagram.

1. A hard hat protects the worker’s ______.
The diagram shows a label “hat” pointing to the yellow helmet on the worker’s head. A hard hat is worn on the head to protect it from falling objects or impacts. So the correct answer is head.

2. Thick boots keep their ______ safe.
The label “boots” points to the worker’s footwear. Boots protect the feet — especially from heavy objects, sharp items, or wet/messy ground. So the correct answer is feet.

3. A hammer helps them ______.
The label “hammer” points to the tool in the worker’s hand. Hammers are used for building — like driving nails into wood or breaking things apart during construction. They don’t help you *see* or *read*. So the correct answer is build.

4. A bright vest helps us ______ the workers.
The label “vest” points to the orange safety vest. Bright vests make workers easy to spot, especially near traffic or machinery. So they help us see the workers clearly and avoid accidents. Correct answer: see.

Now let’s double-check:
- Q1: head ✔
- Q2: feet ✔
- Q3: build ✔
- Q4: see ✔

All match common safety knowledge and the diagram clues.

Final Answer:
1. head
2. feet
3. build
4. see
