The document contains two semi-detailed lesson plans for an 8th grade science class. The first lesson plan is about power and describes calculating power using the formula Power=Work/Time. Example problems are provided to teach students how to calculate power. The second lesson plan differentiates between potential and kinetic energy and explains the work-energy theorem. Students will identify and compare the two types of energy using a Venn diagram. Both lessons aim to teach students key concepts and formulas through examples, activities, and practice problems to evaluate understanding.

Semi-Detailed Lesson Plan in Science 8
Date:
Week No.: Lesson No.:
I. Learning Competencies:
Describe how work is related to power and energy; S8fe-ic-21
Learning Objectives
At the end of the lesson the student should be able to;
a. state the operational definition of power
b. solve problems on power using the formula
Power=Work/Time.
II. Subject Matter
Topic: Power
References: Science Links 2020 page 38-40
Instructional Materials: Laptop, Printed Pictures, and chalk.
III. Lesson Procedures
A. Preliminaries
A1. Prayer
A2. Greetings
A3. Checking of attendance
B. Review/Recap of Previous lesson
C. Motivation
Activity: Pinoy Henyo
Direction: Divide the students into 2 groups. Each group will guess the mystery word that they
have picked.(Ex. Power Time Work) They will be given strictly 2 minutes only to guess the word.
The fastest group who will guess the words wins the game.
D. Presentation/Abstraction
Power
Calculating Power
P=W/t
E. Analysis
Illustration of a big bulb will be posted on the board. Then, ask students what comes to
their mind if they hear the word “Power”.
F. Application: Problem Solving.
Direction: Solve the following problems.
1. A figure skater lifts his partner, who weighs 450N, 1.0 m in 3.0 sec. How much
power is required to do this?
2. Formula: P = W / t
P = 450 Joules / 3 sec.
P = 150 W
2. If this same skater uses 450W of energy to lift his partner the same distance (1 meter)
how long would it take to lift her?
Formula: t = W / P
t = 450 Joules / 450W
t = 1 sec.
3. A student uses 200W of power in 10 seconds to lift boxes onto the back of a truck,
how much work did they do?
Formula: W = P x t
W = 200W x 10 seconds
W= 2000 J
G. Generalization
Ask students what they had learned and then write conclusions on the board. Direct
them to note down the conclusions on their notebooks.
IV. Evaluation: Problem Solving
V. Assignment: What are the two types of energy?
