shape of an object?

3. What force is applied?
What change happened
to the object when force
was applied?
Is it a change in shape
or is there a movement of
an object?

4. What force is applied?
What change happened
to the object when force
was applied?

or is there a movement of
an object?

6. 1. Go to your working area
silently.
2. Work cooperatively.
3. Observe safety measures.
4. Keep your area clean.

7. Can magnets pull objects?
Magnets are materials that can attract or move
objects.
Magnets have an invincible magnetic field.
Horseshoe

rectangular
magnet
bar magnet

8. What are the materials or objects
that can be attracted by a magnet?

9. Activity 1 – HOOK ME UP
What to do?
1. Identify the objects that can be attracted by
magnet using your magnet
2. Wave your magnets inside the box and take a
turn at pulling out the objects attracted by magnet.
3.Then, answer the worksheet by writing the name of
objects attracted by magnet and objects not
attracted by magnet.

10. 4. Record your observations on the table.
Objects Attracted by
the Magnet
Objects Not Attracted
by the Magnet

11. Discussion
Guide Questions:
1.What happened when the materials were placed
near the magnet?
2. What are the objects attracted to your magnets?
3. What are the objects not attracted by your
magnets?

12. .
Magnetic materials are objects
attracted by magnets.
These materials are made up
of some metals like nickel
,iron and cobalt.
Magnetic

13. .
Non - Magnetic materials are
objects not attracted by magnets.
These materials are made up of
plastic , rubber , wood and styro.
Non-Magnetic

Discoverers

16. GROUP FINDERS:
Look at the pictures on
the map . Put a connecting line
on the objects that you think
would attract to a magnet.

17. GROUP FINDERS:
From the magnetic map, copy
and draw the non- magnetic
materials found in the map.

18. GROUP DISCOVERER:
Hunt the different pictures of objects
under your chairs, sort the objects into
magnetic and non magnetic, then
paste them on the correct honey
treasure display jar.

19. 1. Go to your working area
silently.
2. Work cooperatively.
3. Observe safety measures.
4. Keep your area clean.

21. What are the magnetic objects made
up of?
What are the non - magnetic objects
made up of?

34. Generalization
What can a magnet do to an object?
What materials are attracted by magnets?
How about non-magnetic objects?
What materials are not attracted by magnets?

35. Generalization
Magnets have invisible magnetic fields
which are attracted to a certain metal.
Magnets do not attract all metals. Objects
made of nickel, iron, and cobalt are
attracted to magnets.

36. Assessment
Color red if the statement is correct and blue if it is not.
1. Magnets can attract objects made of wood.
2. Not all magnets have a magnetic field.
3. A horseshoe magnet is a type of magnet.

37. Assessment
4. A metal spoon is an example of a magnetic
object.
5 . Magnets can attract all materials.

38. Assignment
