Physical Change

7. occur when matter
changes its property but
not its chemical nature.
Physical Change
The material still remains
as it is.
Physical property is a change
in: size and shape.

8. Example of
Physical Change
“
Cutting of paper
Crumpled paper
Stretching rubberband

9. Example of
Physical Change
“
Breaking eggshell
Chopped meat
Bending wire

10. Example of
Physical Change
“
Cutting a thread
Breaking a stick
Smashing rock

11. are changes matter undergoes
when it becomes new or
different matter.
Chemical Change
The product is a new
material.

13. How can we tell its chemical
change?
Heat & light
A chemical change occurs when
fireworks are used. Fireworks are
made of metals such as magnesium
and copper. These change chemically
as they light up the sky.

14. How can we tell its chemical
change?
Bubbles
It bubbles (makes a gas)

15. How can we tell its chemical
change?
color
 It changes color because of heat

in the rain.

31. Physical or Chemical Change
“

an axe.

32. Physical or Chemical Change
“
Materials undergo chemical change in different ways.
During the change process, one or more new
materials with different compositions can be formed.
For the chemical reaction to happen heat energy or other
substances are needed to break the bonds of molecules.
The speed rate of chemical reaction in different
materials depend on temperature, presence of light,
pressure, and presence of catalyst, and electricity.

33. What are the properties of iron and rust? Do
they have the same properties?
Iron easily combines with
oxygen to form rust. Rust is
soft and powdery. It is weak.
Iron is one material that is very hard.
Because of its hardness and strength. It is
used to build cars, bicycles, window, grills
and other machines

34. What acts as a catalyst
in rusting?
Water increases the rate at which iron rusts.
Water acts as a catalyst in the process of
rusting. A catalyst is a material that speeds
up chemical change. However, it itself does
not change

35. Is there a new material formed during
chemical changed?
Sometimes when a
material changes, it
doesn’t look like the
original material. Its
composition becomes
different. This kind of
change is called
chemical change

36. Can it be brought back to
original form?
The properties of the new materials are
different from the original ones.
When a material undergoes a chemical
change, the new material formed cannot be
brought back to its original form
Burning is an example of chemical change. It
produces

37. What happens to charcoal after
burning?
What new material will be formed if
you burn fire woods?
Some chemical
reactions take place
rapidly. Others take
place slowly

41. WASTE SEGREGATION

42. WASTE SEGREGATION
is the sorting and separation of waste types
to facilitate recycling and correct onward
disposal.

43. IMPORTANCE
1. it reduces the amount of waste that reaches
landfills, thereby taking up less space.
2. Pollution of air and water can be considerably
reduced when hazardous waste is separated and
treated separately
3. Help maintain the cleanliness of the
environment

44. WASTE SEGREGATION
RECYCLABLE
SPECIAL
WASTE
RESIDUAL WASTE

45. BIODEGRADABLE WASTE
These are wastes that can be
decomposed by microorganisms
into simpler, more stable
substances.
It can be made into compost or
biogas.

46. BIODEGRADABLE WASTE

47. NON-BIODEGRADABLE WASTE
These are wastes that cannot be
decomposed or dissolved by
natural agents.
They remain on earth for
thousands of years without any
degradation.

48. NON-BIODEGRADABLE WASTE

49. RECYCLABLE
SPECIAL
WASTE
RESIDUAL WASTE

50. RECYCLABLE WASTE
Any waste materials retrieved
from the waste stream and free
from contamination that can still
be converted into suitable
beneficial use.
