> Only some objects can make their own light, including fires, lamps and ____________. They are examples of ____________ of light.
> Some ____________ are also able to make their own light, such as fireflies.
> Our star is called the Sun. Without the ____________ from the Sun reaching Earth, ____________ could not grow and life would not exist.
> There are many different stars and we can see some of them in the sky on a ____________ and clear night.
> Light from an ____________ which produces light can hit the surface of another object which does not produce light and bounce off it. This is called ____________ of light. It can cause light to change ____________.
> At night, not all the shining lights in the sky are stars. Some of the brightest lights we see on a dark night are ____________, such as Mars, Venus and Mercury. They do not produce their own light, but we can still see them! In fact, we can see many different objects which do not ____________ any light because light can be ____________.

1. "Only some objects can make their own light, including fires, lamps and ____________."
→ Fires and lamps are man-made sources of light. The next logical example is stars (they emit their own light).
✔ Answer: stars
2. "They are examples of ____________ of light."
→ Objects that emit light are called sources of light.
✔ Answer: sources
3. "Some ____________ are also able to make their own light, such as fireflies."
→ Fireflies are animals. So, animals can produce their own light (bioluminescence).
✔ Answer: animals
4. "Without the ____________ from the Sun reaching Earth..."
→ The Sun emits light, so without light, plants can't grow.
✔ Answer: light
5. "...____________ could not grow and life would not exist."
→ Plants need sunlight for photosynthesis.
✔ Answer: plants
6. "We can see some of them in the sky on a ____________ and clear night."
→ You can only see stars clearly when it's dark.
✔ Answer: dark
7. "Light from an ____________ which produces light..."
→ An object that produces light is a source.
✔ Answer: source
8. "...bounce off it. This is called ____________ of light."
→ When light bounces off a surface, it's called reflection.
✔ Answer: reflection
9. "It can cause light to change ____________."
→ Reflection can change the direction of light.
✔ Answer: direction
10. "Some of the brightest lights we see on a dark night are ____________, such as Mars, Venus and Mercury."
→ These are planets.
✔ Answer: planets
11. "They do not produce their own light, but we can still see them! In fact, we can see many different objects which do not ____________ any light..."
→ These objects don’t produce light.
✔ Answer: produce
12. "...because light can be ____________."
→ We see them because light is reflected off them.
✔ Answer: reflected

This passage teaches the concept of light reflection. It explains:
- Sources of light (like the Sun, stars, lamps) produce their own light.
- Non-luminous objects (like planets and moons) don't produce light but reflect it.
- Reflection allows us to see these objects.
- Light changes direction when reflected.
- Even though planets don't produce light, they appear bright at night due to reflected sunlight.
This helps students understand why we see things that don’t glow themselves — because light is reflected off them!
