12 Minutes
Activity Notebook
Activity 2: 3 stations
Measuring spoons
Let the learner group with 5 members. Let them create 3 2 beakers
working stations in their designated place and let them conduct Sugar
a simple experiment.
Water
Sand
1st Station
Marker
Procedure: put equal amounts of water in 2 beakers
4 Watch glass
Label the beakers 1 and 2
Salt (crystal)
Add ½ tsp of salt in beaker 1
Copper coin
Add 1/ 2 tsp of sand in beaker 2.
Guide Questions:
1. What happens to the particles of salt in
water and sand in water?
2. What is the appearance of salt mixed in
water and sand mixed in water?
2nd station
Procedure: Label the 2-watch glass with 1 and 2
Put a pinch of sugar in watch glass 1
Put a spoonful of sugar in watch glass 2
Guide Questions:
1. What is the difference between a pinch of
sugar in watch glass A and a spoonful of
sugar in a watch glass B?
2. Is the sugar changes into another form?
3. What if I will add another pinch of sugar to
the watch glass A, Is the sugar changes into
another form?
3rd station
Procedure: label the watch glass with A and B
Put the salt in watch glass A
Put the coin in watch glass B
Guide Questions:
1. What is the chemical composition of copper
coin?
2. What is the chemical composition of salt?
3. What is the difference between the 2?
EXPLAIN (Teach the concept. Should include interaction
between teacher and students). 15 Minutes
Student’s output
The teacher will then call a representative in each group to
present their outputs.
After their presentation, the teacher will ask to the class the
following questions:
1. Based from the results of the experiment, do you think
sugar is a substance? If yes, then justify your answer.
2. From the given materials (salt, sand, sugar, coin) which
of these are substance and why?
3. What is your bases in identifying a substance?
Key Concept:
The particles of salt mixed with water was dissolved while
the particles of sand was just suspended at the bottom. The
appearance of salt when mixed in water disappears and will
totally dissolve in water resulted to uniform appearance which
is said to be homogeneous.
Sand when mixed in water will not dissolved. Therefore,
Sand mixded in water did not possess uniform appearance,
therefore, it is not a homogeneous.
The chemical composition of a pure substance is always
the same regardless of amount or origin. Sugar will always be
sugar regardless of its amount by mass.
Copper is one of the elements found in the periodic table
which is also known as an element (simplest form of a pure
substance and cannot be broken down into simpler substances).
Salt is a combination of sodium and chlorine when mixed,
known as sodium chloride. A combination of two or more
elements is known as compound (combination of two or more
elements). Element and compound is one of distinct properties
of a pure substance
ELABORATE (Students apply the information learned in the
Explain. The teacher will give inputs to deepen the
understanding of the students) 12 minutes
Unknown
Let the student group together and let them observe and Beaker
investigate an unknown. Let them write their observations in Water
their activity notebook and answer the guide questions:
Salt
Note: The unknown can be a sugar and water solution, salt
solution, coffee, milk and others.(salt solution)
1.
2.
3.
4.
How many phases is seen in the unknown?
Is the appearance of the unknown the same?
Does the unknown have the same chemical composition?
Is the unknown an element, compound or not a substance?
Justify your answer.
5. Is the unknown a substance? State the properties that
justify that it is a substance.
Key concept:
Substance has 3 properties:
•
it has uniform appearance or it is homogeneous
•
chemical composition is always the same regardless of
the amount or origin
•
it can be element or compound
EVALUATE. 5 minutes
1/2 Crosswise
TRUE or FALSE. Write T if the statement is true and F if
otherwise.
_____1. Pure substance can be further
broken down into simplier substance.
_____2. Element simplest form of a pure
substance and cannot be broken down into
simpler substances.
_____3. The appearance of salt when mixed
in water disappears and will totally dissolve
in water resulted to uniform appearance
which is said to be homogeneous.
_____4. The chemical composition of a
pure substance is always not the same
regardless of amount or origin.
_____5. Element and compound is one of
distinct properties of a pure substance.
For number 6-8. Please give what is asked.
6-8. Give the three properties of pure
substance.
For numbers 9-10. What property of pure
substance is present when sugar is dissolved
in water? And why?
EXTEND (Deepen conceptual understanding through use in
new context). 6 minutes
List 10 substances found in your house and list their
properties.
