This ppt will help learners and teacher to understand the topic of how heat being transferred through solid materials. We will learn how heat transfer to solid materials and how it is important to know it.

2. AT THE END OF THE LESSON, THE LEARNERS
SHOULD BE ABLE TO:
•1. Differentiate conductor materials and insulator materials.
•2. Appreciate the importance of learning about heat transfer.
•3. Actively participate in discussions about real-life examples
of heat transfer.

3. PRE-TEST
a) Through conduction
b)d. Through vacuum
3. What happens to solid when
heated?
a.It remains the same?
b.It increases the volume.
c.It increases the temperature.
d.It increate the water level
1. What is the direction of heat transfer?
a)From hot to cold
b)From bottom to top
c)From cold to hot
d)From side to side
2. How heat transferred from in solid
materials?
a)Through convection
b)Through radiation

4. 4. What happen to a solid when it is continuously exposed to heat?
a.It may become heavier
b.It may decrease in volume
c.It may expand
d.It may melt
5. It is the materials through which heat passes slowly or not at all.
a.Convection
b.Conduction
c.Temperature
d.Insulator

5. MOTIVATION
•Group yourselves into two. Write CONDUCTOR and
INSULATOR on the board based on the picture shown.
The group who got the highest score will be the winner!

12. How heat transferred through solid?
•The transfer of heat through solid materials is called
conduction.
•Conduction is the heat transfer through a substance or from a
substance to another by direct contact. Everything is made up
of small particles. When the particles are moving faster, there
is more energy and the temperature is higher.

13. •There are materials that allow heat to flow easily. It is
called CONDUCTORS. Metals are good conductors
that why we use them as cooking utensils because
heat moves fast through metal pan to the food.
•There are materials through which heat passes slowly
or not at all. It is called INSULATORS.
•Insulators are wood plastic, fabric and ceramic.

14. Application: Look at the pictures below. Write INSULATOR
or CONDUCTOR in the space provided for materials in the
pictures.
