LABORATORY ACTIVITY: STATE, PROPERTIES, AND CHANGES OF MATTER
1. Draw example of physical and chemical changes that occurred in an orange fruit and in a cake.
(a) Orange fruit Physical change
(c) Cake Physical change
2. Identify physical and chemical changes that occurred in your home or community. Give at two
examples of physical changes and two examples of chemical changes. Document (take a photo) these
changes and provide explanations for your examples.
Physical Changes
cutting of tomato
> cutting of tomato is a
physical change as
only the shape and
size of the tomato is
changed but there is
no chemical change in
the tomato.
Grating Cheese
>Grating cheese is a
physical change
because the cheese is
not changing its
identity; just its state-
from solid cheese to
small shavings.
rotten mango
>this is a chemical
change because there is
something new made:
mold,and the chemical
make up of the mango is
different so the change
isn't reversible making it a
chemical change.The fruit
has also probably begun to
change color,smell bad and
change texture.
(b) Orange Fruit Chemical change
(d) Cake Chemical change
