- The lesson plan is for a 45-minute science class on waves for 13-14 year old boys. - The objectives are for students to understand that waves transmit energy rather than matter, classify waves as transverse or longitudinal, and distinguish between these two wave types. - The lesson will include reviewing periodic motion, defining waves, demonstrating transverse and longitudinal waves using slinky toys and videos, checking concepts, and having students work in groups to apply their understanding through a quiz and worksheet.

A Science Model Lesson Plan
Waves: (introduction)
Class:Preparatory two
Date:1 st/3 / 20 17 Duration: 45 minutes
Class profile:
40 boy students, ages13– 14. Their proficiency in the English Language is good but their scientific and general knowledge are
partial.
Time-table fit:
 In the previous lessons the SS learned about periodic motion and the oscillatory motion as a type of periodic motion, etc………
 In this lesson, they will learn about waves because of oscillatory motion .And how the wave can transfer energy through matter
or spacefrom one location to another. In addition, waves types.
 In the following lessons, the SS will learn more about wave's properties.
Measurable Objectives:
By the end of this lesson, the SS should be able to:
 Use necessary lab tools to Investigate that waves transmit energy, not matter, through disturbances or vibrations
(Cognitive domain 4: analyze)
 Classifythe waves depending on their characteristic as. (Cognitive domain 4: analyze)
 Distinguish Between longitudinal and transverse waves. (cognitive domain 2: understand)
 Appreciate the value of cooperative and team work.(affective domain)

Anticipated problems:
Academic:
1. SS may not remember or understand the background information needed for the lesson.
Solution: Remind & clarify during the leaden and recycling stage.
2. SS may find carrying out the investigations difficult.
Solution: Demonstrate and monitor (giving guidance when necessary).
Disciplinary:
3. SS may become too noisy and hurt themselves in the class.
Solution: Alert to follow instructions and rules & Keep a careful eye on the naughty SS and away them from Each other.
Materials and Visual Aids:
 Lesson plan notebook, White board markers, laptop, (Data show),
 Laboratory tools and objects: spiral slinky, Tuning fork.

Greetings
T: a joke related to the lesson.
Teacher shows a photo for jelly. In addition, ask who
loves jelly.
T: yesterday I felt thirsty then I went to the fridge to drink
but I found the jelly oscillate vibrate very hard and very
disturbance
I said to jelly "do not be afraid I am just come to drink not
to eat you"… it is a joke laugh. Laugh. Laugh.

 Before we start our lesson let, we do a small
revision.
 What is energy?
 Can we do work or make a change without energy?
 How can we transfer energy from one location to
another?
 Our lesson today about waves

T: You got one minutes to share with someone beside/
behind you About waves in the life. Give for examples
T: discus SS answer and show a slide that ended by: we
leave in world of waves.
World of Waves
There are lots of waves all around us in everyday
life.
You can drop a rock into a pond and see waves form
in the water( water waves).
Sound is a type of wave that moves through matter
and then vibrates our eardrums so we can hear.
Light is a special kind of wave that is made up of
photons that helps us to see.
We even use waves (microwaves) to cook our food
really fast.

Wave
definition&
types
to Investigate that waves
transmit energy, not matter,
through disturbances or
vibrations. And Classify
the waves depending on
their characteristic as.
 The SS will do an activity with teacher's help to
conclude a definition for waves.
 scientists use to classify waves into various categories
T: we can classifiy waves acoroding to oscillation
direction to energy travel direction into two types :let we
investigate them throughthis activity and this flash:
While you see the flash T ask SS todiscribe the direction
of the oscillation to the enrgy travel direction

https://www.youtube.com/watch?v=AtlxBODxWHc
 And we can classifiy waves acoroding to the ability of
wave to transfer through spaceand matter
Some waves require a medium to transfer through it
We call it mechanical waves. If a wave can travel without
a medium, (for example, through space), we call it an
electromagnetic waves.

To check that SS
understood
1. Waves are simply different means for transferring
energy. Is that true?
2. Waves created when a source of energy causes a
medium to expand. True or false?

 From the next slide answer the question
 You are going to work in four teams of three students
each.
 Write T if the statement is true or F if the statement is
false.
 If the statement is false, change the underlined word to
make it true. Write your changes on the lines provided.

1- Morad is the tallest one in the class
2- Mohamed is the tallest one in the class
1- T
2- F (Morad )
Write your answers in one sheet for each group.
We have 5 minutes to run the activity.

1. Mechanical waves are waves that move through
matter or empty space.
2. Sound is a mechanical wave travels only through
matter.
3. A wave in which the disturbance is perpendicular to
the direction the wave travels is called a

5. Light is a wave, which the energy moves,
perpendicular to the direction of the particle
movement.
6. A wave in a rope consists of compressions and
troughs.
7. transverse waves consistof a series of crests and
rarefactions
