grade 7

2. Most Essential Learning
Competency:
Infer the conditions
necessary for heat transfer to
occur. (S7LT-IIIh-i12)

3. Objectives:
a. define heat
b. identify and distinguish the
methods of heat transfer;

4. Objectives:
c. distinguish conducting materials from
non-conducting materials; and
d.cite some examples of heat transfer
used in everyday life

5. Direction: Study the poem and
answer the guide questions.
Heat’s Everywhere
Poem Analysis

6. Guide Questions:
1. What is ‘heat’ as stated in the
poem?
2. What are the three methods of
heat transfer stated in the poem?

7. Guide Questions:
3. How do you differentiate heat
from temperature?
4. What is conductor?
5. What is insulator?

8. - called as “energy in transit”.
- an energy that is transferred from
one object to another object due
to the difference in their
temperature.
1. HEAT

9. 2. Methods of Heat Transfer
1. Conduction
2. Convection
3. Radiation

10. HEAT is as “energy in transit”.
Temperature refers to the
hotness or coldness of an object
and it measures energy.
3. Heat vs. Temperature

11. - allows the transfer of
heat easily.
- is to metal objects
Ex: Iron Nails
Conductor

12. - do not allow transfer of
heat easily,
-is to plastic objects
Ex: Plastic cups
Insulators

18. Video Analysis
Direction: Study the video and
identify statements that best
describe conduction,
convection and radiation.

19. Video Analysis

20. In convection the heat was
transfer through vibration
without the atoms and
molecules leaving their original
position.
True or false

21. In conduction the mode of heat
transfer in which atoms or
molecules actually move to
transfer the heat.
True or False

22. In Radiation no
medium is required
for the transfer of
heat
True or False

23. Objects with dark
surfaces absorbed more
heat than objects
with bright surfaces.
True or False

24. Dark color is good
absorber of heat and
good emitter of heat
True or False

25. Bright color is poor
absorber of heat and
poor emitter of heat
True or False

Question: Is it safe to the
man to use the metal pole
without wood or plastic on
the handle? Why?

31. Directions: Give at least one
scenario for each method of heat
transfer (Conduction, Convection
and Radiation) which you can
observe taking place at home or in
your neighborhood.
Heat transfers every day!

32. Heat transfers every day!
For example: Conduction – A metal
spoon becomes hot from the
boiling water inside the cup as I
make coffee.
Write your answer on a manila
paper.

33. WORD SEARCH
Directions: Look for the words
being described in each of the
statements below.

34. WORD SEARCH

35. 1. Thermal energy that is in transit.
2. Mode of heat transfer that does not
need particles or a medium to take
place.
3. A material that does not allow the
transfer of heat easily.
