This document discusses luminous and nonluminous materials. Luminous materials produce their own light, such as light bulbs and fireflies. Nonluminous materials do not produce their own light but reflect light, like the moon and most objects we see at night. Students are asked to identify examples of luminous and nonluminous materials and to draw or collect pictures of examples for their science notebook.

1. Luminous and Nonluminous
Materials
Science Grade 3
Third Quarter

2. Review:

3. Some materials give off their own
light.
They are called luminous materials.
Luminous materials are used as
sources of light.

4. There are also luminous animals
such as:

5. Those objects that cannot produce
their own light are called nonluminous
materials.
Examples are:

6. How about the moon?
At night, the moon is bright and
seems to give off light.
However, the moon is not
a luminous object, it does
not produce its own light.
It only reflects the
light from the sun.

7. Can you tell me now what is luminous
and nonluminous materials?
Give 2 examples of luminous
materials.
Give 2 examples of nonluminous
materials.

8. Put a check mark (/) on the luminous objects and a
cross mark (x) on the nonluminous objects.

9. Homework:
Draw or cut pictures of 5 luminous
and 5 nonluminous materials.
Paste it on your Science notebook.
