The document discusses changes in materials when exposed to different conditions such as temperature or when mixed with other materials. It describes how materials change phases from solid to liquid to gas depending on temperature, giving examples of ice melting as temperature increases and water boiling at 100°C. It also discusses physical changes like melting and chemical changes like burning that can occur when materials are heated or cooled. Finally, it defines mixtures as substances made by mixing materials without chemical reaction, and describes heterogeneous mixtures where each material is visible and homogenous mixtures where the materials are evenly mixed together.

This article is focused on an in-depth assessment of the K to 12 curriculum of the Philippine Educational system. It aimed to identify the misalignment of the teaching pedagogies as mandated by RA 10533 in the sound idea of the widely spreading concept of learner centeredness. This article is premised on the assumption that many Filipinos, including Filipino teachers are complacent on the implementation of the K to 12 curriculum not noticing the deviation of foundations to the constitutional aim of learner-centeredness. Furthermore, in an attempt to analyze the K to12 curriculum, this article comprehensively looks into the foundations and connection to learner-centeredness to provide articulation in the new curriculum. Qualitative-Content Analysis is the instrument of research to achieve the objectives of the study. There is no other participant in this study aside from the researcher in order to minimize subjectivity in the description of the content and to prevent further interwoven interpretation in the analysis. Through descriptive analysis, this article takes into account the official statements of the education department in the enumeration of fluctuations. A topical analysis across RA 10533 descriptor was qualitatively presented through MSWord. This paper reveals the strong need for the articulation in the curriculum, which calls for an in-depth review of content of curriculum.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2. Changes in Materials
In this new lessons, you are expected to
describe changes in the properties of materials
when exposed to certain conditions such as
temperature or when mixed with other
materials.
3. Try to sip some iced tea or cold water while you
are going through all the learning tasks in this
module. What did you feel? Don`t you know that
cold water have more dissolved oxygen that`s why it
feels better to sip cold drinks than a non-cold
drinks? Recall what happened to ice cubes when
they were exposed to heat. The ice cubes melted.
What made the ice cube melted? See figure 3. below.
4.
5. Effect of Temperature in the Phases of Materials
At constant pressure, the state of materials
depends on the temperature by which they are
exposed. The ice cube or the solid phase of water,
as seen in Figure 3 above will melt if taken out of a
freezer and stayed long at room temperature. The
water that boils turned into gas or vapor that comes
out of the kettle if left at high temperature for too
long.
6. Temperature is the measurement of the
amount of heat energy present in the
surroundings. There is an exchange of heat
between the substance and the surroundings.
This means that heat can be absorbed by the
materials or can be released by the materials.
7. When the heat is absorbed by the
materials, the temperature will increase, thus
the material is hot. If heat is removed or
released by the materials, temperature will
decrease, thus it is cold.
8. Temperature varies depending on the
environment from where the materials are
exposed. For example, we feel very hot during
summer days because of the intense heat of the
sun. Some places in our country registered a
temperature of 40 °C.
9. This is very hot because our normal body
temperature is about 37 °C. If your temperature
is above 37°C , you may experience fever. This
is the reason why you are advised by doctor to
take medicine and take plenty of water to lower
the temperature.
10. Another changes in the materials due to the
application of heat is called melting. This
process that happens when solid material
changes into liquid form. The heat coming from
the environment made the ice cubes melted
when they are removed from freezer.
11. The temperature in the freezer is O °C (read
as zero degree centigrade or zero degree
Celsius). Thus, when ice cubes were exposed to
heat in the environment, the high temperature of
the environment caused the melting of ice
cubes.
12. Generally, an increase in the temperature
turns solids into liquids (melting), liquid to solid
(freezing), liquid into gases (evaporation), solid
into gas (sublimation), and boils water at certain
point (boiling ).
13.
14. When materials reached its melting point,
solid materials changed into liquid. The
temperature at which the liquid will change back
to solid is called its freezing point. The melting
point of ice is 00C, this is also the freeing point
of water. The boiling point, or the temperature at
which water boils, and turned into gas is 100 °C .
15. That is why water exists in three phases
depending on the condition by which its exposed
to different temperature. If the change is from gas
to liquid as the temperature falls below it, it is the
condensation point.
16. The state of substances in solid, liquid or gas
phases is largely determined by its temperature.
At each threshold level of temperature, the
material will change its state. These changes
may either be physical changes or chemical
changes.
17. Physical changes like melting of ice cubes, lighted
candles, floor wax, margarine , chocolate bar, crayons,
and butter resulted to changes in their shape, sizes
and texture. There are no new materials formed.
When cooled, these materials recover their original
physical state.
18. Metals expand when heated and contracts when
cooled. They resulted to changes in size. Some
materials when exposed to heat or different conditions
of temperature resulted to chemical changes. Burning
of woods and matchsticks turned the materials into
ashes.
19.
20. Combustion of engines results to burning of fuels that
causes the cars and airplanes to move or run its functions.
Combustion, also known as burning, is the basic chemical
process of releasing energy from a fuel and air mixture. In
an internal combustion engine (ICE), the ignition and
combustion of the fuel occurs within the engine itself. The
engine then partially converts the energy from the
combustion to work.
21. Change in Materials When
Mixed with Other Materials
Mixture is a substance made by mixing other
substances together. It is the product of the random
distribution of one substance through another without
any chemical reaction, as distinct for a compound. ike
in halo-halo and wet clothes where water is mixed with
the fabric.
22. Types of Mixtures
Mixed materials can be classified depending on the
appearance of the resulting mixture. When solid materials
are mixed with solid materials, each of the combined/
mixed materials can be easily identified/ distinguished from
one another. These mixtures are called heterogenous
mixtures. In halo-halo, you can easily identify or distinguish
the ingredients . It is a heterogenous mixture. Each
property of the materials in heterogenous mixtures do not
change. Their sizes, shape and color remain the same after
mixing them together.
23. Some solid materials when mixed with other solid
materials cannot be distinguished from each other. The
resulting mixture looked the same all throughout. When
sugar is dissolved in water, you cannot distinguish sugar
in the solution. This kind of mixture is called homogenous
mixture. Examples of these are liquid medicines, sugar
and a salt solution. Examples of homogenous mixtures
include salt dissolved in water or a salt solution and juice
drinks.
