INQUIRY TRAINING MODEL

PRELIMINERY DETAILS

Name of the teacher: Priya Raj. R

Name of the school: Govt.H.S.S.Punalur

Subject: Physics

Class: IX

Unit: Wave Motion

Topic: Transverse wave

Date: 10/08/2015

Duration: 35 min

CURRICULUM STATEMENT

Through inquiry, observation, discussion and knowledge acquisition, the learner develop the concept of wave motion

and transverse wave.

FOCUS

A. CONTENT RELATED

The learner acquires knowledge and understanding about the following terms, facts and concepts.

a. scientific terms: wave motion, transverse wave

b. Facts: Wave produced in rope is transverse in nature.

: Ripples formed in water is transverse in nature.

Concepts: Wave transmit energy from one point of a medium to the other points without the actual translator motion

of the particles. They undergo only vibrations. The transmission of energy in this manner is a wave motion.

B. PROCESS RELATED

The learner becomes able to acquire the following process skills.

Observe activities in group

Asks questions related to the event.

Communicate in groups.

Defines concept from teacher’s explanation.

SUPPORT SYSTEM

Chalk, blackboard, laptop, tray.

SOCIAL SYSTEM

Cooperative learning in small groups.

EXPECTED EFFECTS

a. Instructional: The students develop the idea of wave motion and transverse wave.

b. Nurturant: the student develop cooperation and learning skills.

PRE-REQUISITES

a. Cognitive domain: General knowledge about wave and vibration

b. Affective domain: Interest to know more about wave motion.

c. Psychomotor domain: Skill to do activities.

CLASSROOM INTERACTION PROCEDURE

Teacher starts the class by asking the students whether they have seen floating boats or sea.

Teacher prepares the students for inquiry procedure.

To prepare students to ask questions giving yes/no answers regarding the floating event.

"Hold a rope straight, which was tied at the other end and a ribbon tied around the rope. Then the rope is moved up

and down".

The teacher prompts the children to ask questions related to this event. The students ask the following questions.

Is it a wave motion?

Is the direction of the wave from the holding and to the tied end?

Does the ribbon undergoes only up and down motion?

Does the ribbon changes its position?

Does the wave transmit energy through the rope?

Take some shallow tray with some water in it. Place some thermocole in the water. When producing vibrations in water

ripples are formed by disturbances.

From the above activity, teacher gives the following explanation.

Disturbance produced is changed into waves on the surface of water and it starts f rom the point of disturbance.

Thermocoal both move up and down when the wave travels.
