This document is a science module from the Department of Education in the Philippines about the particle nature of matter. It contains 3 activities for students to explore properties of matter and how matter is composed of tiny particles. The activities involve observing samples of different materials, mixing salt and water, and adding food coloring to water. The module explains John Dalton's atomic theory and how atoms and molecules are the smallest fundamental units that make up matter. An analogy is provided that likens matter to pointillist paintings, with continuous images emerging from individual dots or particles.
Sound is produced when a matter vibrates. Sounds consists waves and these waves travel as a longitudinal waves. Sound travels fastest in solids because the particles are closer. The speed of sound depends on the temperature of matter. The higher the temperature, the higher the speed of sound is. The properties of sound are reflection and refraction. In reflection, the sound wave turns back when it hits a barrier. A good example of this are echoes and reverberations. On the other hand, refraction is the bending of sound waves.

Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.

THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.

What I Need to Know
This module was designed and written in a way that suits your understanding and needs.
The lessons presented will help you acquire mastery in explaining the properties of solids,
liquids, and gases based on the particle nature of matter (S8MT-IIIa-b-8). The module
includes activities on distinguishing matter from non-matter and the composition of which
materials are made of. All these will prepare and help you understand the next lesson. The scope
of this module permits it to be used in many different learning situations. This module is about:
Lesson 1: Matter
Specific Objectives:
1. Describe common properties of matter; and
2. Infer from observations about the composition of matter.
What's In
In Grade 7, you recognized a wide array of materials that combine in many ways and
through different processes. By engaging in simple scientific investigations, you classified
materials based on observed properties as homogeneous and heterogeneous mixtures, elements
and compounds, metals and non-metals, and acids and bases.
Not everything is matter nor made of matter. Every day you encounter phenomena (events)
that involve non-matter. By observing things around you, you begin the task of answering the
basic question – What is matter? What are things that are non matter?
Activity 1: It Does Matter! (Matter or Non-Matter)
Objectives:
After performing the activity, you should be able to:
1. Describe common properties of matter; and
2. Distinguish properties of matter from non-matter.
Materials Needed:
1 tablespoon of table salt (sodium chloride) in a small cup
1 cup of tap water
1 piece stone
½ cup of rice or corn (grains/kernels or milled)
1 piece balloon (or any cellophane wrap/plastic bag)
4 small wide-mouthed bottles or cups
weighing scale

C. Post-Activity Tasks
Complete Table 1 (Identifying Matter) by answering the Post Activity column. Some
of your answers may be different from the Pre-Activity Task.
Matter surrounds us on a daily basis. Each has its own unique characteristics that
make it different from others. The characteristics that describe a sample of matter are called
properties. An unknown substance can be identified by observing and measuring its
properties and comparing them to the properties recorded in the chemical literature for
known substances.

What is It
THE BEGINNING
According to Thales of Miletus, all things came from water, and the Earth itself floats on
water. A century after Thales' death, Leucippus, a Greek Philosopher, conceived the idea of
indivisible units called atoms (meaning 'uncut'). This idea was developed in the late fifth and early
fourth centuries B.C. by Democritus, a student of Leucippus.
Democritus believed that any piece of matter could be divided and subdivided into very
small particles, but this process ended at some point when a piece is reached that could not be
further divided. His belief about matter being composed of tiny particles led him to use the term
atomos (which later became atoms) to describe these ultimate particles. Democritus' ideas about
the atom were later challenged by other Greek philosophers, most strongly by Aristotle, who
rejected the idea of the atomism of matter.
Today, we know that although atoms are very small, they are not indivisible as Democritus
thought, rather they consist of still smaller particles. Democritus was right in one aspect of his
belief, that is, atoms are the smallest particles of which substances are made.
JOHN DALTON'S ATOMIC THEORY
In the early nineteenth century, John Dalton, an English scientist,
performed experiments with gases. His results convinced him that matter was
made up of tiny, indivisible particles. Dalton observed that the same amounts
of hydrogen and oxygen always combine to form a given amount of water. He
reasoned that each element must be made of its own unique kind of particle
and that these particles combine in simple ways.
Based on his experiments, Dalton developed a theory of the structure
of matter. His theory contained four main concepts:
1. All matter is composed of tiny, indivisible particles called atoms.
2. Atoms of each element are exactly alike. Atoms of different elements are different in some
fundamental way or ways.
3. Atoms can combine with other atoms to form compounds. Atoms can combine in simple
numerical ratios such as 1:1, 1:2, 2:3, and so on.
4. Atoms are reorganized during a chemical reaction but not changed.

Q8. Think about food coloring and
water as made up of particles. Give
your reason(s) for the observations you
made in Q6. You may draw
illustrations to justify your reason(s).
Part C.
Get inside your room. Close the door and
windows. Stand at one corner. Ask
someone to spray the perfume or
cologne at the opposite corner of the
Q9. What did you observe? Give reason(s)
for your observation.

9. 7
ATOMS & MOLECULES
An atom is the smallest particle of an element that has all the
properties of the element. Atoms are too small to observe. These
particles cannot be seen under the high-powered light microscopes used
in school laboratories. The size of an atom is measured in Angstroms.
One angstrom is a unit of length equal to one ten-millionth of a
millimeter.
The best light microscope can magnify an image only about
1,500 times. Electron microscopes create a highly magnified image of
up to 1 million times. The scanning tunneling microscope (STM) allows
scientists to view and scan the surface of very small particles like atoms.
It can magnify an image 10 million times. The STM creates a profile of
the surface of an atom, and then a computer-generated model or
contour map is produced. So, only a model of the surface of an atom is
generated by a computer when a scanning tunneling microscope is used. The picture of atoms
generated is unlike the picture we take with our cameras.
A molecule is a particle consisting of two or more atoms combined together in a specific
arrangement. It is an electrically neutral particle. It is the smallest particle of an element or
compound that can exist independently. For example, a molecule of water (H2O) consists of an
oxygen atom combined with two hydrogen atoms. Atoms of the same element can also combine to
form a molecule. For example, oxygen in the air consists of oxygen molecules, which are made up
of two oxygen atoms, O2.
In Activity 2, when you mixed salt and water and tasted the resulting solution, it tasted
salty because salt is still present, though you cannot see the salt anymore. The volume of the
mixture is less than the sum of the volumes of the unmixed salt and water. Why is this so? The
water is made of tiny particles, molecules, with spaces between them. Salt is also made up of
molecules bigger than the molecules of water. The water molecules could fit in the spaces between
the salt molecules or vice versa.
ANALOGY: ATOMS AND POINTILLISM
A good analogy to consider related to matter being composed of tiny particles, is the
pointillist style of painting. The images in a pointillist painting appear continuous, but if one looks
closely, the images are actually made of small dots. Pointillism is a method of painting using dots
to come up with various effects. The dots are placed singly, in rows, or randomly. These dots can
also be in groups, or they can be overlapping. They can be either uniform or varied in size in the
same painting. Matter is similarly assembled, with atoms of different elements combining in
various ways to give a tremendous variety of substances.

In Figure 1(a), the image of Dolores
F. Hernandez, founding Director of the

Development was done through pointillist
painting. The image appears continuous. In
Figure 1(b), a portion of the painting (boxed
in Figure 1a) is blown up to show that the
continuous image actually consists of dots.
The lightness and darkness of the pigments
give volume to the image in order to show
smoothness. Similarly, matter, which
appears to be continuous like the image in
Figure 1(a) is made up of very small
particles that cannot be seen with the
unaided eye.

Answer Key Gr8Q3 Module 1
Activity 1: It Does Matter!
Table 1 (Post Activity)
Q1. Masses of the samples can be measured. They
all occupy space.
Q2. Yes, each sample occupies space inside the
cup.
Q3. The water overflowed. The stone takes up part
of the space previously occupied by water.
Q4. Yes, blowing air inside inflates the balloon.
Q5. Using a weighing scale, mass of samples can
be measured. (mass of sample = mass of sample &
container - mass of empty container)
Q6. No, heat and light do not have mass. They do
not occupy space because they are not matter.
Heat is energy in transit and light is a form of
energy.
Activity 2: What Am I?
1. mass 6. Malleability
2. volume 7. ductility
3. density 8. conductivity
4. Impenetrability 9. flexibility
5. texture 10.elasticity
Activity 3: What is matter made of?
Q1. The mixture tastes salty.
Q2. The salt is still present though we cannot see it
anymore. The salt particles mixed well with the
water particles.
Q3. Volume is a little more than 2 but less than 3
cups.
Q4. The volume of the resulting mixture is less
than the sum of the volumes of the unmixed salt
and water.
Q5. This shows that water is made up of tiny
particles with spaces between them. The salt
particles are able to fit into these spaces because
the salt particles that dissolved are very small.
Q6. The food coloring spreads slowly towards the
bottom and began to spread throughout the water.
Q7. After one day, the food coloring has totally
spread throughout the water since the resulting
mixture has a color almost the same as that of the
food coloring.
Q8. The particles of food coloring are able to fit
into the spaces of the water molecules.
Q9. Smelled the perfume from a distance. The
perfume particles fit into the wide spaces of air
particles and are scattered throughout the
room.

My Final Farewell
Farewell, dear Fatherland, clime of the sun caress'd
Pearl of the Orient seas, our Eden lost!,
Gladly now I go to give thee this faded life's best,
And were it brighter, fresher, or more blest
Still would I give it thee, nor count the cost.
On the field of battle, 'mid the frenzy of fight,
Others have given their lives, without doubt or heed;
The place matters not-cypress or laurel or lily white,
Scaffold or open plain, combat or martyrdom's plight,
T is ever the same, to serve our home and country's need.
I die just when I see the dawn break,
Through the gloom of night, to herald the day;
And if color is lacking my blood thou shalt take,
Pour'd out at need for thy dear sake
To dye with its crimson the waking ray.
My dreams, when life first opened to me,
My dreams, when the hopes of youth beat high,
Were to see thy lov'd face, O gem of the Orient sea
From gloom and grief, from care and sorrow free;
No blush on thy brow, no tear in thine eye.
Dream of my life, my living and burning desire,
All hail ! cries the soul that is now to take flight;
All hail ! And sweet it is for thee to expire ;
To die for thy sake, that thou mayst aspire;
And sleep in thy bosom eternity's long night.
If over my grave some day thou seest grow,
In the grassy sod, a humble flower,
Draw it to thy lips and kiss my soul so,
While I may feel on my brow in the cold tomb below
The touch of thy tenderness, thy breath's warm power.
Let the moon beam over me soft and serene,
Let the dawn shed over me its radiant flashes,
Let the wind with sad lament over me keen ;
And if on my cross a bird should be seen,
Let it trill there its hymn of peace to my ashes.
Let the sun draw the vapors up to the sky,
And heavenward in purity bear my tardy protest
Let some kind soul o 'er my untimely fate sigh,
And in the still evening a prayer be lifted on high
From thee, 0 my country, that in God I may rest.
Pray for all those that hapless have died,
For all who have suffered the unmeasur'd pain;
For our mothers that bitterly their woes have cried,
For widows and orphans, for captives by torture tried
And then for thyself that redemption thou mayst gain
And when the dark night wraps the graveyard around
With only the dead in their vigil to see
Break not my repose or the mystery profound
And perchance thou mayst hear a sad hymn resound
'T is I, O my country, raising a song unto thee.
And even my grave is remembered no more
Unmark'd by never a cross nor a stone
Let the plow sweep through it, the spade turn it o'er
That my ashes may carpet earthly floor,
Before into nothingness at last they are blown.
Then will oblivion bring to me no care
As over thy vales and plains I sweep;
Throbbing and cleansed in thy space and air
With color and light, with song and lament I fare,
Ever repeating the faith that I keep.
My Fatherland ador'd, that sadness to my sorrow lends
Beloved Filipinas, hear now my last good-by!
I give thee all: parents and kindred and friends
For I go where no slave before the oppressor bends,
Where faith can never kill, and God reigns e'er on high!
Farewell to you all, from my soul torn away,
Friends of my childhood in the home dispossessed!
Give thanks that I rest from the wearisome day!
Farewell to thee, too, sweet friend that lightened my way;
Beloved creatures all, farewell! In death there is rest!
I Am a Filipino, by Carlos P. Romulo
I am a Filipino–inheritor of a glorious past, hostage to the uncertain
future. As such I must prove equal to a two-fold task–the task of
meeting my responsibility to the past, and the task of performing
my obligation to the future.
I sprung from a hardy race, child many generations removed of
ancient Malayan pioneers. Across the centuries the memory comes
rushing back to me: of brown-skinned men putting out to sea in
ships that were as frail as their hearts were stout. Over the sea I see
them come, borne upon the billowing wave and the whistling wind,
carried upon the mighty swell of hope–hope in the free abundance
of new land that was to be their home and their children’s forever.
I am a Filipino. In my blood runs the immortal seed of heroes–seed
that flowered down the centuries in deeds of courage and defiance.
In my veins yet pulses the same hot blood that sent Lapulapu to
battle against the first invader of this land, that nerved Lakandula
in the combat against the alien foe, that drove Diego Silang and
Dagohoy into rebellion against the foreign oppressor.
The seed I bear within me is an immortal seed. It is the mark of my
manhood, the symbol of dignity as a human being. Like the seeds
that were once buried in the tomb of Tutankhamen many thousand
years ago, it shall grow and flower and bear fruit again. It is the
insignia of my race, and my generation is but a stage in the
unending search of my people for freedom and happiness.
I am a Filipino, child of the marriage of the East and the West. The
East, with its languor and mysticism, its passivity and endurance,
was my mother, and my sire was the West that came thundering
across the seas with the Cross and Sword and the Machine. I am of
the East, an eager participant in its spirit, and in its struggles for
liberation from the imperialist yoke. But I also know that the East
must awake from its centuried sleep, shake off the lethargy that has
bound his limbs, and start moving where destiny awaits.
I am a Filipino, and this is my inheritance. What pledge shall I give
that I may prove worthy of my inheritance? I shall give the pledge
that has come ringing down the corridors of the centuries, and it
shall be compounded of the joyous cries of my Malayan forebears
when first they saw the contours of this land loom before their eyes,
of the battle cries that have resounded in every field of combat from
Mactan to Tirad Pass, of the voices of my people when they sing:
“I am a Filipino born to freedom, and I shall not rest until freedom
shall have been added unto my inheritance—for myself and my
children and my children’s children—forever.”
