Lesson Plan of Introduction to Conductor & Insulator

General Science Grade IV

Students’ Learning Outcomes

·         Distinguish betwixt insulators together with conductors.

·         Identify examples of conductors together with insulators inwards their environment.

Information for Teachers

·         Materials are of dissimilar kinds. Some deport electricity together with other don’t.

·         Those materials through which electrical electric flow tin give notice transcend are called conductors spell the materials through which electrical electric flow can’t transcend are called insulators.

·         Let the students pose the conducting together with non-conducting materials inwards an activity.

Materials / Resources

A bulb amongst holder, cells/batteries, erasers, wooden pieces, pieces of copper wire, pieces of Fe wire, coins, ball points, pencils, textbook

Worm upward action

·         Ask approximately questions, similar the following:

v  Why is the get of an electrical Fe made of plastic or wood?

v  Why are the electrical wires covered amongst plastic or thread?

v  Why does an electrician wearable plastic gloves earlier working amongst alive wires?

Development

Activity 1

·         Divide the students into suitable groups. Ensure the availability of resources for the activity.

·         Prepare a circuit every bit shown inwards the figure.

·         Ask the students to insert the given things ane past times ane betwixt the opened upward terminals of circuit together with discovery bulb.

·         Ask the students: Why does the bulb glow past times inserting approximately materials together with non past times inserting the others?

·         Write their responses on the board together with and thus state them that materials that permit the bulb to glow are materials through which electrical electric flow tin give notice pass. The materials which don’t permit electrical electric flow to transcend (bulb doesn’t glow)

·         Ask them: Which of the materials deport electricity together with which ones don’t?

(Expected response: Electricity tin give notice transcend through the materials similar Fe wire, copper wire together with money etc. together with can’t transcend through the materials similar wood, cloth, plastic)

·         Now state the students that iron, copper, wire coil, etc. are conductors spell wood, cloth, plastic etc. are insulators.

·         Write all the observations of action on the cast of tabular array on the board together with inquire the students to it together with and thus consummate it. 

Material provided	Conducts electricity	Doesn’t deport electricity	Conductor/Insulator
Wood
Copper wire
Plastic sheet
Iron rod
Cloth piece

Sum upward / Conclusion

·         Some materials are conductors together with approximately are insulators.

·         The materials which deport electricity are called conductors.

·         The materials which don’t deport electricity are called insulators.

Assessment

For the amend agreement of the students inquire the next questions:

v  Does the electrical electric flow menstruum through all the materials?

(Expected response: No, electrical flow can’t transcend through all the materials. It tin give notice transcend through the conductor only).

v  Can all materials which deport electricity too deport heat?

(Expected response: Yes skilful conductors of electricity are too skilful conductors of heat).

Follow up

Make a listing of conductors together with insulators inwards your surroundings other than mentioned above.
