A Semi-Detailed Lesson Plan in Science 10
Grade 10 – Matter
Fourth Grading Period
I. Objectives
At the end of the lesson, the learners should be able to:
a. state Charles’ Law
b. describe changes to gases caused by the addition and absence of heat (rise and fall in
temperature)
c. investigate the relationship between volume and temperature at constant pressure of a
gas
II. Subject Matter
A. Topic: Charles’ Law
B. References: Department of Education Science Learners’ Module pp. 369-372
C. Materials: smart TV, chalk, board, eraser, rubber balloons, tape measure, beakers,
thermometer
III. Methodology
A. Preliminary Activities
1. Opening Prayer
2. Checking of Attendance
3. Classroom Management
4. Motivation
The teacher will show picture of scenes in Miracle in Cell No. 7 and ask them to guess
the film. Students will be asked, “What is your favorite scene from the film?” There is
a hot air balloon scene from the movie and from there other possible laws aside from
Charles’ Law will be introduced.
Teacher will also recapitulate Boyle’s Law from the previous lesson.
B. Activity
The teacher divides the students into six groups. Each group will perform Activity 3
Charles’ Law in Science Learner’s Module 10 pp.369-371.
Activity 3
Charles’ Law
Objectives:
Investigate the relationship between volume and temperature at constant pressure.
Materials:
• rubber balloon
• hot water
• thermometer
• tape measure
• tap water
• ice
Procedure:
1. Prepare 3 beakers (1 for ice water, 1 for tap water, and another 1 for hot water).
2. Inflate a balloon.
3. Measure the circumference of the balloon using a tape measure.
4. Get the temperature reading of the hot water.
5. Put the balloon in hot water for 2 minutes, then measure again its circumference.
6. Do three trials and get the average of the results.
7. Repeat procedures 3 to 6 using tap water.
8. Repeat procedures 3 to 6. This time use ice water.
C. Analysis
Students will report to the class the results of their activity in a table. Each group has a
reporter to present their tabulated results.

Guide Questions:
Q1. What happens to the size of the balloon as the temperature decreases?
Q2. How does the change in the temperature relate to the volume of gas in the balloon?
Q3. Were your predictions from the pre-lab correct? Explain.
D. Abstraction
Using a PowerPoint presentation with concepts and pictures, the teacher will discuss
Charles’ Law and the relationship of volume and temperature at constant pressure. To better
understand the law, teacher will also show the relationship between volume and temperature
using PhET simulation on the smart TV.
E. Application
PICK ME!
Based on the lesson and their prior knowledge, students will pick real-life applications of
Charles’ Law from a series of pictures the teacher will show.
IV. Evaluation
IDENTIFICATION. Write the word/s referred to in the following statements.
1. A state of matter that has volume, mass, temperature, and it also exerts pressure
2. The lowest attainable temperature identified by Lord Kelvin, a Scottish physicist
3. Force per area exerted on the gases measured in atmospheric units
4. He was the French chemist who proposed that the volume of gas is directly proportional to
temperature.
5. Space occupied by a gas and its SI unit is liter.
6. Depends on the kinetic energy of the gases and usually measured in Celsius or Fahrenheit
7. The unit used to indicate absolute temperature of matter
8. It is the lowest attainable temperature discovered by Lord Kelvin.
9. This law states, “At constant pressure, the volume of a fixed amount of gas is directly
proportional to the Kelvin temperature.”
10. The gas law that combines of Boyle’s, Charles’, and Gay-Lussac’s laws
