Lesson Lesson Innovation Of Natural Together With Artificial Magnets Full General Scientific Discipline Shape Iv

Lesson Plan of Natural in addition to Artificial Magnets

General Science Grade IV

Students’ Learning Outcomes

·         Investigate using a magnet that unopen to materials are “magnetic” in addition to unopen to are “nonmagnetic”

·         Recognize that a magnet has 2 poles.

Information for Teachers

·         Some materials are magnetic in addition to unopen to are non-magnetic.

·         Magnetic materials are those which are attracted past times the magnet.

·         Non-magnetic materials are those which are non attracted past times the magnet.

·         A magnet has 2 poles. One is called the North Pole in addition to the other is called South Pole.

·         The magnet number of a magnet is the strongest at the poles.

Material / Resources

Bar magnets, pencils, steel clips, pieces of wood, plastic objects, rulers, combs, erasers, steel nails, Fe filing, textbook

Worm upwards activeness

·         Ask the students how many of them accept seen a magic slice of metallic which attracts the Fe pieces.

·         What practise they telephone telephone it?

·         Now demonstrate a bar magnet to the class.

·         Demonstrate that magnet attracts steel pins or clips.

Development

Activity 1

·         Divide the students into groups.

·         Give each grouping a bar magnet, unopen to magnet in addition to unopen to non-magnetic materials.

·         Ask students: Do you lot intend a magnet volition line all types of things?

·         Ask the students to exam this holding of magnet past times bringing it close all the given objects plow past times turn.

·         After they accept tested, inquire them to position the things which are attracted past times the magnet in addition to which are non attracted.

·         Tell them that things which are attracted past times the magnets are called magnetic materials in addition to things which are non attracted past times magnets are called non-magnetic materials.

·         Ask the students to write the names of magnetic in addition to non-magnetic objects inward split upwards columns inward their notebooks.

·         Ask them what is mutual holding inward all the magnetic materials

 

Activity 2

·         Give a bar magnet in addition to unopen to Fe filings to each group.

·         Ask them to house a magnet on a paper.

·         Sprinkle the Fe filings on to the bar magnet in addition to tap the tabular array gently.

·         Observe the filing stuck to the bar magnet.

·         Ask the students, are the filings evenly stuck to all parts of the magnet?

·         Disturb the filings in addition to repeat the procedure in addition to encounter what happens.

·         Ask the students questions like:

v  On which parts of the magnet, are the Fe filings to a greater extent than oft than non stuck?

(Expected answer: At their ends)

v  Why are the Fe filings stuck to a greater extent than at the ends?

(Expected answer: Magnet is stronger at the ends)

v  What practise you lot telephone telephone the ends of the magnet?

(Expected answer: Poles of the Magnet)

·         After this discussion, inform the students that the ends of magnet are called contrary poles in addition to and then innovate the price of North Pole in addition to South Pole.

Sum upwards / Conclusion

·         The materials which are attracted past times the magnet are called equally magnetic materials

·         The materials which are non attracted past times a magnet are called non-magnetic materials.

·         Most of the Fe filings are attracted towards the ends of the magnet. These ends are called poles.

·         There are 2 poles of a magnet. One is the North Pole in addition to other is the South Pole.

Assessment

·         Make a tabular array on the board in addition to inquire them to re-create it inward their notebooks.

·         Divide the students into groups.

·         Provide each grouping the materials given inward the table.

·         Ask the students to predict, without using the magnet or non in addition to and then tape their observations inward the table. Instruct them pose a tick inward the correct column.

·         Provide each grouping a magnet in addition to learn them to exam the objects in addition to tape their observations inward the given table.

Sr. no.	Materials	Prediction		Result
		Will live attracted past times magnet	Will non live attracted past times magnet	Attracted past times magnet	Not attracted past times magnet
	Wooden Strip
	Iron nail
	Coin
	Plastic ruler
	Steel ruler
	Cotton
	Pencil
	Paper clips
	Brass wire
	Copper wire

Follow up

·         Prepare a listing of magnetic in addition to non-magnetic materials acquaint at your habitation or environment other than discussed inward the classroom.
