🔬 Introduction to Solutions, Solubility, and Concentration
This video lesson is designed for science students to explore the concepts of solutions, solubility, and concentrations. It begins with a pre-activity quiz to gauge the students' prior knowledge on measurement, asking them to measure various substances and materials. The quiz includes measurements in milliliters, degrees Fahrenheit, inches, and grams. Following the quiz, the lesson introduces key vocabulary: solute, solvent, solution, soluble, and insoluble. The video uses these terms to explain that a solute is a substance that dissolves in a solvent, forming a solution. The lesson differentiates between solute and solvent, with a solute being soluble in a solvent and an example being sugar dissolving in water, while sand, which does not dissolve, is considered insoluble. The video then narrates a story about a sugar family to illustrate the concept of solubility, emphasizing why the sugar children would not want to go out in the rain. The lesson concludes with an experiment where students are instructed to mix salt with water to observe the formation of a saltwater solution, highlighting the properties of solutions and the roles of solute and solvent in this context.
🧪 Experimentation and Understanding Solute-Solvent Relationships
The second paragraph delves deeper into the experiment of distinguishing between solute and solvent. It provides a step-by-step procedure for an experiment involving salt and water, emphasizing the observation that the salt disappears, indicating the formation of a solution. The video explains that solutions are homogeneous mixtures where the solute is dissolved within the solvent, and they cannot be separated by simple filtration. The lesson clarifies that in a saltwater solution, salt is the solute and water is the solvent, with water being the more abundant component. It also discusses the universal solvent property of water. The video then challenges students to identify the solute and solvent in various scenarios, such as making fruit drinks with powder juice and water, or when salt is dissolved in the mouth after an injury. It uses these examples to reinforce the understanding of solutes and solvents and their quantities in solutions. The lesson concludes with a formative assessment quiz that tests students' comprehension of the concepts learned, including the behavior of juice powder when mixed with water and the identification of the solvent in a cup of milk.

Okay good day to all science students in
this video lesson under solution
solubility and concentrations we are
going to tackle the components of a
solution we have the activity solute and
solvent so before we proceed to the
activity and lesson We are going to have
first we have to measure first your
previous knowledge about measurement so
write down the measurement of each of
the following substances or material for
number one Okay 8.9 ml number two 90 de
Fahrenheit number
3 17 mL for 2.8 in and Number 5 120 gram
Okay use the terms in the vocabulary box
below to fill in the blanks each term
should be used once only then write a
sentence to show your understanding so
ito Iyung vocabulary words we have
solute we have solution soluble
insoluble and solvent so number one a
blank is a substance dissolves into a
solvent Ano kayaang sagot Tingan natin
sa sentence so a solute is a substance
that dissolves into a solvent number two
plank is a liquid in which a solute
dissolves in two So ano kayang sagot so
a solvent is a liquid in which a solute
dissolves in2 number 3 a blank is a
mixture of solute dissolved in a
solvent so the answer a solution is a
mixture of a solute dissolved in a
solvent number f sugar is blank in water
the answer should be sugar is soluble in
water number five sand is blank in water
so sand is insoluble in water o Sana
naintindihan natin yung pagkakaiba dito
sa vocabulary words na to Dito pa lang
maintindihan na natin What is the
difference between solute and solvent
but as we go further mas maiintindihan
pa natin What is the
difference ito Alam na alam na natin
itong kantang ito lalo na yung mga nung
elementary days Ano po once a time in a
far away land a sugar family lived in a
small house in the forest when it was
summertime the three children were happy
for they could Play outside but during
rainy Seasons They were all sad and just
stared at the window and sing Rain Rain
Go Away Rain Rain Go Away Come again
another day all the children want to
play Three Times Why do you think
children are afraid to go out of their
house during rainy days So from the name
of of their family they are sugar family
meaning Anong mangyayari sa kanila pag
naulanan maybe they will be dissolved in
water So what will happen to the
children if they go out of the house
while raining Why so they are soluble in
water ang sugar po kasi is soluble in
water so let us proceed to the activity
of students components of
solution perform an experiment to
determine the differences between solute
and solvent So kanina ibinigay lang
natin yung definition ng pagkakaiba ng
solute and solvent Here we are going to
to make an actual experiment to
differentiate solute from solvent So you
need one teaspoon salt beaker and water
for instructions you are going to carry
out an investigation to know the
differences between solute and solvent
and found out their role in a solution
so for procedure we have We need 20 mL
of water Pero dito sa experiment po na
ginawa natin is ito Matagal ng
experiment po ito doon sa old curriculum
pa about properties of solution Pero ito
na ung ginamit nating video Tingan po
natin Ayan one spoon of salt nilagay po
sa that is 100 mL ang ginamit natin na
tubig
150 soyo maramirami and pinaghalo natin
So mapapansin po natin nawala na yung
Asin so one appearance so meaning This
is a solution combination of salt and
water or salt water
solutionan po sa experiment nating
salain yung
solution kung masasala ba yung Asin kasi
isa po sa property ng solution it cannot
be separated it cannot solution cannot
be separated by filtration so meaning
hindi kayang salain yung Asin po Ayan
for task or questions What is formed
when salt is added to water of course
salt water solution is formed in a salt
water in a salt solution which is the
solute Okay the solute is the Bakit
siyaang solute it dissolves in water
kung alin ang natunaw yun ang solute in
a salt solution which is the solvent Why
Okay water is the solvent because it
dissolves the salt yung pantunaw yun ang
solvent at ang watering pala water is
considered as universal solvent another
one What component of the solution exist
in greater amount so ang greater amount
po diyan is yyung solvent or yyung tubig
at yyung lesser amount smaller amount is
the solute or yyung salt meaning isa po
sa katangian ng ah sa pagkakaiba ng
solute in solvent maliban sa yung solute
ang tinunaw solvent ang pantunaw ang
solvent po Mas marami siya compared sa
solute so smaller amount yung solute ang
greater number greater amount is the
solvent so discuss the differences
between solute and solvent ay a solute
is a substance that dissolve into a
solvent and it exist in a smaller amount
a solvent is a liquid in which a solute
dissolves into and it exists in greater
amount so identify the solute and
solvent for each of the following
solutions J
water and powder juice to make a fruit
drink alyan ang solute m ang solvent
Okay the solvent is the water and then
the solute is the powder juice Okay Mak
swi salt water in his mouth after he
lost his tooth in a Basketball game so
which is the solvent again water the
solute is the salt Okay J put a ring
alcohol on the grass stain that was on
his solent alcohol solute diyan is the
stain Kylie added a little sugar to his
tea because it tasted bitter Ayan solute
ang sugar and tea is the solvent Okay
the tea from Irish bag tea bag colored
the water as it broad which is the
solvent of course water na naman Alin
ang
solute Okay the tea using this diagram
again We are going to differentiate
component the components of solution
Okay dalawang components we have the
solute and then the solvent o ano ang
characteristics ng solute so a solute is
a substance that dissolves into a
solvent and it exists in a smaller
amount and solvent a solvent is a liquid
in which a solute dissolves into and it
exists in greater amount so sample ng
solute we have sugar salt powdered juice
solvent water vinegar alcohol May
nagtanong po niyan dati Paano kung
pinaghalo mo ay vinegar and water which
is the solvent and which is the solute
So kung alin niyo Mas marami ang amount
ang percentage composition yun ang
solvent So kung 7 kagaya ng alcohol
75% Mas marami ang alcohol doon so the
water water is the solute in that case w
yyung Mas marami yun yyung
solvent so for formative assessment
which is an example of a solution What
will be the answer ca water the two
components of a solution are solute and
solvent which State describes the solute
it is the solid form in a solution it is
the liquid component of the solution it
is the component of a solution in a
smaller quantity it is the component of
a solution in a bigger quantity Okay Let
us
see which happens if you mix juice
powder with water the juice powder will
dissolve in water the juice powder will
form a layer the juice powder will not
dissolve in water the juice powder will
settle at the bottom of the Water so the
answer is letter a the juice powder will
dissolve in water okay Number Four What
is the solvent in a cup of milk ano
diyan Okay water in a solution What do
you call the substance in a Larger
amount so that is solvent
