Examples of physical changes from the provided options include:
1. **Folding some paper to make a model airplane** - This is a physical change as the paper is still paper and only its shape has changed.
2. **Shattering a glass** - This is also a physical change because the glass breaks into pieces, but its chemical composition remains the same.
The other two options are not physical changes:
- **Combining hydrogen and oxygen to make water** - This is a chemical change, as new substances are formed (water).
- **Cooking an egg** - This is also a chemical change because the proteins in the egg undergo a change that transforms them into a different substance.
So, the correct answers are:
- Folding some paper to make a model airplane
- Shattering a glass
