PowerPoint Presentation
Daily Goal: We will be able to compare physical and chemical
properties Homework: Finish creating your data table and graph from
your science fair experiment due today, finish physical/chemical
foldable and revise your test by tomorrowNovember 7Q2 - pg.
5Science starter: (Answer this in your notebook):List 5 physical
characteristics that you can observe about a person.
Parts of the Ear and Test Preparation Q2 - PG. 1Physical and
Chemical Changes IntroQ2 PG. 3Physical and Chemical PropertiesQ2
PG. 5Table of Contents Quarter TwoGuess That Physical Property!The
Way to Play:I will put a slide on the board.I will give you 2-3
minutes. During that time, you and your partner will try to figure
out what the pictures have in common. Write down your answers in
the same order as the slides (i.e. answer #1 for slide #1).At the
end, you will have a chance to see how many physical properties you
got right.
And the answers areColorOdor (smell)Melting PointFreezing
PointBoiling PointConductivity (ability to transfer
electricity)Solubility (ability to dissolve things)Density
Write these in your notebook under the title, Physical
Properties of Matter. You will have 2 minutes.
Switch Partners! What about chemical properties?
And the answers areFlammability (how easily it burns)Reactivity
(What happens when you mix it with another substance? A good
indication of a chemical reaction is if it produces bubbles. But
that doesnt always mean its chemical! Think about boiling
water.)Oxidization (What happens when it is exposed to oxygen?
Rusting is an example of oxidization.)Write these in your notebook
under the title, Chemical Properties of Matter. You will have 3
minutes.
So whats the difference between chemical and physical
properties? Look at the pictures of chemical and physical changes.
Figure out what is the difference between what is happening in a
physical change and what is happening in a chemical change.Make a
rule for what can happen during a physical change and what cannot
happen. You will have 2 minutes per slide.
Example:Breaking a graham cracker can be a physical change,
because it doesnt change the graham cracker. Eating a graham
cracker (digesting it), cannot be a physical change, because you
change the graham cracker to a new substance.
Create a Rule:
Chemical Change:Physical Change:

Physical Change:Chemical Change:Physical Change:
Chemical Change:Physical Change:
With a new partner, share the rules that you created. Generate
(come up with) a list of similarities and differences between
physical and chemical changes.Create a Venn Diagram to compare the
ways that physical and chemical changes are alike and different.
List as many ways as you can think of. You will have 10
minutes.
