Teacher: Virgilio R. Paragele
Content: Unit 1: Module 3: Heat and Temperature
Content Standard: The learner demonstrate an understanding of heat and temperature
and its effect on the body.
Performance Standard: The learner shall be able to determine the heat absorb or heat
released of an object, using the specific heat capacity.
Grade level: 8 Carnation
Learning Area: Science
Materials:
Beakers 4 pcs 250mL oil 500 mL
Beakers 4 pcs 500mL water 500 mL
Thermometer 4 pcs Stove 1 pc
Teacher Activity Student Activity
Preliminary
Let us pray Everybodywill pray
1.Elicit
Why do you think, some objects
are hot while the others are
cold?
Students will give some ideas
about heat.
2.Engage
Asses the students ideas about
heat, the heat transfer and
change in temperature.
Let the students answer some
questions,and compute the
change in the temperature, with
corresponding amount of heat
absorb or release.
3.Explore
Give the students different
forms of activity, then let them
give their answers to the class
Students will follow the steps
and follow the instructions in an
activity for differentiated
instructions.
Differentiated Activity
Note. All liquids must be of the same initial mass and temperature.
Give instructions and questions to each group.
Group 1. Temperature variation: record their temperature after 3 minutes
Group 2. Liquid variation(oil, and water) time reach five degrees Celsius increase
4.Explain
Explain the concept and correct
the errors made by the reports
as students answers.
Listen and participate in the
discussion for calculation of
heat
5. Elaborate
Let the students review and
repeat the activity
In Students will repeat their
experiment and finalize their

2. answers.
6. Evaluate
Give quiz to asses the students
understandings of heat transfer.
Students will draw the direction
of heat and solve for amount of
heat. Then justify the answer

2. Whenyoudive intothe swimmingpool atTimoga at 7am. Did yourelease heat orabsorb heat?
7.Extend
How did the water and oil affect
the rate heat transfer? Can they
share the heat to their containers?
How will they absorb heat from
the container?
Students in different groups will
give their ideas or answers.

3. Group 1:
Materials : 2 beakers, oil, water, water on the kettle, thermometer,
stove
Procedure:
1. Put the hot water on the 2 pcs 500mL
2. Put into separate beakers the water and oil with the same mass.
3. Record the temperature of the oil and water in the beaker on
table 1
4. Put the hot water into the 500mL beakers , put the two 250mL
beakers into the boiling water, and make sure that the water in
the 500mL is 1/3 of the height of the 250mL beaker.
5. Record their temperatures after 2 minutes on table 1.

Guide Questions:

2. Which of the liquid absorbs heat slower?
3. How much heat is absorb in the water?
4. Is it the same to the amount of heat absorbed by the oil?

4. Group 2:
Materials : 2 beakers 250mL, oil, water, hot on water on 500mL(2pcs)
thermometer
1. Put water on one beaker and oil on the other beaker. They must
have the same mass.
2. Record the initial temperature of the water and oil on table 2
3. Put the hot water onto the 500mL beakers about 1/3 the height of
the 250mL beakers
4. Put the two beakers simultaneously on the hot as you start your
timer.
5. Record the time when the temperature of the liquid on the
beaker reaches 5 degrees Celsius increase on the table 2.
