Problem Explanation
The task on the worksheet is to
circle the objects that give off their own light. This means we are looking for items that
produce light rather than just reflect it.
---
Step-by-Step Analysis of Each Object
Let’s go through each image and determine whether it gives off its own light:
1.
Firefly (top left)
✔ Yes – Fireflies produce their own light through bioluminescence.
2.
Moon (top center)
✘ No – The moon does not produce its own light; it reflects sunlight.
3.
Sun (top right)
✔ Yes – The sun emits its own light through nuclear fusion.
4.
Cell phone (middle left)
✘ No – While a phone screen can emit light, the object itself isn’t inherently a light source unless turned on. But in this context, it's depicted with a glowing screen? Let's look: the screen shows a green display, so
yes, it is emitting light.
✔ Yes – The phone screen emits light when on.
5.
Pot of food (middle center)
✘ No – Food doesn't emit light. Even if hot, it doesn't glow visibly like a light source.
6.
Light bulb (middle right)
✔ Yes – A light bulb produces light when turned on.
7.
Pen (right side)
✘ No – A pen does not emit light.
8.
Diamond (bottom left)
✘ No – Diamonds reflect light but do not produce their own light.
9.
Lantern (center bottom)
✔ Yes – A lantern contains a flame or light source that emits light.
10.
Bird (pink bird)
✘ No – Birds do not emit light.
11.
Flashlight (bottom left)
✔ Yes – A flashlight emits light when turned on.
12.
Glasses (bottom center)
✘ No – Glasses reflect or refract light but do not produce it.
13.
Star (bottom center-right)
✔ Yes – Stars (like our sun) produce their own light via nuclear reactions.
14.
Candle (bottom right)
✔ Yes – A lit candle produces its own light.

Final Answer: Circle These Objects
You should circle the following:
- Firefly
- Sun
- Cell phone (if screen is lit)
- Light bulb
- Lantern
- Flashlight
- Star
- Candle
> 🟩
Correctly circled objects:
> 🔹 Firefly
> 🔹 Sun
> 🔹 Cell phone (with glowing screen)
> 🔹 Light bulb
> 🔹 Lantern
> 🔹 Flashlight
> 🔹 Star
> 🔹 Candle

Summary
✔ Objects that give off their own light:
- Firefly
- Sun
- Cell phone (screen)
- Light bulb
- Lantern
- Flashlight
- Star
- Candle
✘ Do NOT give off their own light:
- Moon
- Pot of food
- Pen
- Diamond
- Bird
- Glasses

This activity helps students distinguish between
luminous (producing light) and
illuminated (reflecting light) objects.
