This document discusses elements, compounds, and mixtures. It provides examples of each, including gold and iron as elements, water and salt as compounds, and describes the key differences between elements and compounds. Elements are made of single atoms that cannot be broken down further, while compounds can be broken down into their component elements through chemical processes.

6. Who can describe what is a
mixture?
1
A mixture is a combination of two
or more substances without
participating in chemical change
or reaction

7. What are homogeneous
mixtures? How about
heterogeneous mixtures?
2
A heterogeneous mixture is consists of
two or more phases while a
homogeneous mixture is consists of
single-phase and also known as
solutions

8. What is substance?
3
Substance is a matter that contains
only one type of atom or molecule

9. Can you give me an example
of a substance?
4
Examples of substances are silicon,
salt, gold, and many more.

13. I think I was lost
My home is too far at any cost
I am tired finding home-made of lead
So that solar radiation will not anymore
be spread,
The heat from Sun makes me float
Like Helium inside a balloon that makes
it bloat
As I go far, I feel numb and bursting
Like a bullet powder made of Potassium
Nitrate that makes us shaking
As I walk in the lonely road above the mountains
It is sad to see land mine of gold and copper be
broken
This shows how the environment suffered much
everyday
Hope my home will be back with me again like a
brand-new day
My body is already in pained and drained
With essential elements from water made up of
hydrogen and oxygen
I want to quench my thirst soon

15. Questioning...
1 Based on the list you have
made what made them an
element or compound?
Each element is consist of only
one type of atom while
compounds are a combination
of two or more elements

16. Questioning...
2
If compounds are consist of two or
more elements, then can we
consider oxygen gas which is
consist of two oxygen a
compound? Why?
No, compounds are consist of
two or more elements while
oxygen gas only consists of one
element which is oxygen.

17. Questioning...
3 Is water a compound? Why or
why not?
Water is a compound since it
consists of two types of
elements which are hydrogen
and oxygen

18. Questioning...
4
If the water is a compound
made of H and O, can we
separate water to become an
element H and O? Why?
Yes, through some chemical
processes compounds can be
broken down into elements.

19. Questioning...
5
Since we can separate
compounds into elements or
vice versa, can you give me
elements that can be turned into
compounds one's exposed to
some naturally occurring
chemical processes?
One example is rust. Rust is
formed when iron reacts with
oxygen

20. Notes...
Elements are made up of atom or
atoms of the same kind. They are
the simplest type of matter and
cannot be broken down into
components.
Some are in the same state but
they have different properties.

21. Notes...
Some elements are
metals
Gold
Silver
Iron
Others are
nonmetals
Nitroge

Oxygen
Hydrog
en
Metalloids...
Boron
Silicon
Germani
um

22. Notes...
Compounds are combination of
two or more elements like water
which is a combination of
Hydrogen and Oxygen.

23. Notes...
Compounds can be broken down
into its components through a
chemical process and formed
when two elements are combined.

24. Activity
Pick one element and
create a chart about it.
Write its symbol, name,
and uses. This will be
written in a long coupon
bond within 5 minutes.

26. Generalization

27. What are
elements? Elements
are made
up of
atoms or
atoms of
the same
kind.

28. Can you give me
three examples
of an element?
Gold
Iron
Hydrogen

29. What are
compounds? Compoun
ds are a
combinati
on of two
or more
elements

30. Can you give me
three examples
of compounds?
Rust
Water
Salt

31. What are the
difference between
elements and
compounds
characteristics?
Elements are
the simplest
type of matter
and cannot be
broken down
into
components. In
contrast,
compounds can
be broken
down into their
components

32. Evaluation
Direction: Identify whether the substance
is an element or compound. Write EL if it
is an element or CO if it is a compound.
1.Baking soda 2. Nickel
3.Salt 4. Hydrogen
Peroxide
5.Helium gas

33. Assignment
Create a Venn diagram showing
the differences and similarities of
mixtures, elements, and
compounds.
