This document discusses experiments performed with microscopes and the examination of cells and carbohydrates. In the first exercise, specimens including a letter "e", skin hair, and mosquito larva are observed under compound and trinocular microscopes at different magnifications. The second exercise explores microscope magnification and how specimens appear larger through calculation of linear magnification. The third exercise examines animal cells from cheek, blood, and egg samples and plant cells from onion and monocot/dicot specimens under the microscope. Key animal and plant cell parts are also described. Finally, the fourth exercise tests whether common foods contain simple or complex carbohydrates through color changes when exposed to iodine solution.

Introduction to the Philosophy of the Human Person - Introduction to PhilosophyJuan Miguel Palero
This is a powerpoint presentation that discusses about one of the core subjects in the k-12 curriculum of the Senior High School: Introduction to the Philosophy of the Human Person. On this presentation, it discusses about the definition, history and nature of the philosophy.
Science and technology studies, or science, technology and society studies (STS) is the study of how society, politics, and culture affect scientific research and technological innovation, and how these, in turn, affect society, politics and culture.
01 - Rizal Law (RA 1425) - Life and Works of RizalHumi
In this slide, we will explore the Rizal Law, a Philippine law that mandates the teaching of the life and works of national hero Jose Rizal. We will also examine the reasoning behind the law and the perspectives of those who disagree with it. Lastly, we will consider whether the law is still relevant in today's society. (Spoiler: The editor is not sure)

What Exactly is Rizal Law?
Rizal Law or RA 1425 is a Philippine law that requires all schools in the Philippines, both public and private, to offer courses on the life, works, and writings of the Philippine national hero, Dr. Jose Rizal.
Why study him?
Why Study Rizal: From The Perspective of Lawmakers
Many Filipinos observed that the sense of Filipino identity was waning. Hmmmm. In response, nationalist policy-makers took action to redirect the nation back to its roots by emphasizing the importance of history as a foundation for national hope and pride.
On April 3, 1956, Senator Claro M. Recto proposed Senate Bill No. 438 and submitted it to the Senate Committee on Education.
“NOLI-FILI BILL”
Senate Bill No. 438, titled "An Act to Make Noli Me Tangere and El Filibusterismo Compulsory Reading Matter in All Public and Private Colleges and Universities and For other Purposes,”
On April 17, 1956, Senator Jose P. Laurel, Sr., who was then the Chairman of the Committee on Education, sponsored the Noli-Fili Bill in the senate and presented it to the Upper House.
“Noli Me Tangere and El Filibusterismo must be read by all Filipinos. They must be taken to heart, for in their pages we see ourselves as a mirror, our defects as well as our strength, our virtues as well as our vices. Only then would we become conscious as a people, and so learn to prepare ourselves for painful sacrifices that ultimately lead to self-reliance, self-respect and freedom.”
The Noli-Fili bill sounds good, right?
NO.
The Catholic Church's Opposition to the Noli-Fili Bill
According to them, the bill was an attempt to discredit the Catholic religion. Since Jose Rizal criticized the Catholic Church, the Noli-Fili bill was met with stiff opposition from the latter’s head and supporters.
According to them, the bill was an attempt to discredit the Catholic religion. Father Jesus Cavanna argued that Jose Rizal’ novels from the past should not be taught in schools because they do not accurately depict current conditions and may give a false impression of the country.
Here are some additional criticisms of the Catholic Church regarding the Noli-Fili Bill:
Among the 333 pages of Noli Me Tangere, only 25 passages are nationalistic while 120 passages are anti-Catholic. 170 lines from Noli Me Tangere and 50 lines in El Filibusterismo were offensive to the Catholic doctrine. The bill might divide the nation. Compulsion to read something against one’s faith impairs freedom of speech and religious freedom. Rizal admitted that he did not only attack the friars who acted deceptively on the Filipinos but also the Catholic faith itsel

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Unit 8 - Information and Communication Technology (Paper I).pdfThiyagu K
This slides describes the basic concepts of ICT, basics of Email, Emerging Technology and Digital Initiatives in Education. This presentations aligns with the UGC Paper I syllabus.
3. MICROSCOPE
• A compound microscope consists of certain
precise mechanical parts (chiefly of metal) to
support and facilitate the use of optical parts (of
glass) that provide the magnified image.
• Although compound microscopes are very
common, the microscopes used in the
laboratory are Trinocular microscopes
4. MICROSCOPE
• Trinocular microscope has two eyepieces
but with a third eyepiece tube for connecting a
microscope camera. It is a binocular with a
moving prism assembly in which light is either
directed to the binocular assembly of the
microscope or to the camera.
5. Parts of a Compound
microscope
Parts of a Trinocular microscope
6. Specimens:
Cut-out of letter e
Skin hair
Mosquito Larva
These are the desired images of
the specimens under a
microscope (taken from the
internet and not the actual photos
from the experiment).
7. • The letter “e” as viewed in the microscope is positioned
upside down while the skin hair and mosquito larva, is
observed to have been magnified, its parts were seen
accordingly, based on the objectives used.
• Low Power Objective (LPO) has a magnifying power of 10x
which means that the specimen is 10x magnified when it is
viewed under the microscope. Meanwhile, HPO (High Power
Objective) has a magnification of 40x which means that, the
specimen viewed under the microscope is magnified 40x.
Thus, specimens are more visible and clear when it is viewed
under HPO rather than LPO. However, only a part/ fraction will
be seen under HPO depending on what you have focused.
9. MAGNIFICATION
• It is defined as the number of items an object is
enlarged or reduced by a lens system.
• It is important to identify the magnification
especially on the microscope used to know how
many times a specimen is magnified and how
it actually differs as seen in the naked eye.
Microscope Magnification:
• Linear Magnification (LM) is the product of the
ocular magnification and the magnification of the
objective or:
• LM = OcM X ObM
10. Linear Magnification (LM)
• Using the Trinocular microscopes, since the
ocular is stamped 10x,
• LM at LPO (Low Power Objective, 10x) :
LM= 10x (10x) = 100x
• LM at HPO (High Power Objective, 40x):
LM= 10x (40x) = 400x
(Note: Scanner, stamped 4x as an objective which is not usually used
to focus but only to scan and have greater field of view of the
specimens before viewing on LPO and HPO, has LM = 10x (4x)=40x .)
11. Magnification of the Drawing
• Formula:
M = SD / SO
• Where:
• M= magnification of the drawing
• SD = size of the drawing
• SO = actual size of the object
(Note: Always remember that the size of the drawing is given
and the actual size of the objects, seashell/ starfish is
measured using a ruler, in mm or cm)
13. Cells
• It is the structural and functional unit of life
• The study of cell, its structure, and its activities is known as
Cytology (now evolved into its progressive alter ego, Cell
Biology)
• Although cells show great diversity in form and function,
all cells are built to a fundamental design and share certain
common features.
• There are two types of cells: Prokaryotic (no true nucleus)
and Eukaryotic (membrane-bound nucleus) organisms.
• In this exercise, we focused on examining Eukaryotic
organisms as such are Animal cells
(oval/spherical/irregular-shaped) and Plant cells
(rectangular shaped).
15. Animal Cells
(with some of its parts)
These are the desired images of the specimens with its parts that can
possibly be seen under a microscope (taken from the internet and not
the actual photos from the experiment).
Cheek cell (400x)
Human blood smear (400x)
Erythrocytes (red blood cells) are
only evident
17. Animal cell parts
• The description below of the parts of an animal cell that
can obviously be seen using the microscopes:
• Cell membrane/ Plasma membrane – the thin limiting
membrane enclosing the cell
• Cytoplasm – materials/ the matrix between the cell
membrane and nuclear membrane
• Nucleus- usually oval or spherical body found or near
center of the cell that is darker or more heavily stained
(Note: These parts are visible when stained with iodine solution)
18. Animal cell parts
• The description below of the parts of chicken egg:
• Yolk – the inner yellow portion of the egg
• Albumin – the egg white, surrounds the yolk
• Vitelline membrane – the thin delicate membrane that
surrounds the entire ovum
• Chalaza- the twisted albumen on the opposite poles of the
yolk
• Blastodisc (germinal disc) – a minute island of whitish
cytoplasm floating on the yolk which will give rise to a new
individual
19. Plant Cells
cytoplasm
Peel of Onion cell
Usually in scraping off
an onion, the parts
that are evident
when viewed under a
microscope are the ff:
Cell wall, cell
membrane,
cytoplasm and
nucelus.
Stomata with guard
cells
These are the desired images of the specimens
with its parts that can possibly be seen under a
microscope (taken from the internet and not
the actual photos from the experiment).
Cell membrane
20. Preserved specimens (Plant)
MONOCOT
Hydrilla verticillata
These are the desired images of the
specimens with its parts that can
possibly be seen under a microscope
(taken from the internet and not the
actual photos from the experiment).
21. Plant cell parts
• The description below of the parts of plant cell that can
obviously be seen using the microscopes:
• Cell walls – the “lines” forming the network between the
individual cells are nonliving cell walls composed chiefly of
cellulose
• Cell membrane – the layer immediately beneath the cell
wall. This encloses the cell cytoplasm.
• Nucleus – appears as a rather dense body in the
transparent cytoplasm; in some cells, the nucleus seems to
belying centrally and will look circular.
(Note: These parts are visible when stained with iodine
solution)
22. Plant cell parts
• Stomata (stoma) with guard cells
-Pores in a plant’s cuticle through which water vapor and
gases (CO2 & O2) are exchanged between the plant and the
atmosphere
• Chloroplast (can only be found in plants)
-Organelle where photosynthesis takes place.
25. ANIMAL CELLS
• Unique parts of the animal cell
• Centriole – a feature of animal cells important for
coordinating cell division
26. PLANT CELLS
• Unique parts of the plant cell
• Cell wall – a feature of plants cells that functions like stiff
lattice-like wall which helps plant cells maintain their
structure and shape
• Chloroplast – a feature of plant cells that allows plants to do
photosynthesis and make their own glucose from sunlight,
water and carbon dioxide
29. • In Food science – polysaccharides are starch
and fiber.
• Polysaccharides are complex carbohydrates.
Starch and fiber are complex carbohydrates.
• Mono and di saccharides are simple
carbohydrate. Sugar is a simple carbohydrate.
• Simple carbohydrates are digested faster and
give you quick energy.
30. FOOD SAMPLE COLOR SIMPLE OR COMPLEX
1. Flour Dark blue-black comples
2. Sugar Brown tan simple
3. Apple Brown tan simple
4. Potato Dark blue-black complex
5. Bread Dark blue-black complex
6. Honey brown-tan simple
7. Vanilla wafer dark, blue-black complex
8. Marsmallow (inside) brown-tan simple
9. Banana dark, blue-black (green)
Brown-tan (ripe)
complex
simple
*These are the desired results of the experiment however, it may
vary upon groups since after putting iodine solution, the color will
not be evident and may take a long while; this might be confusing
(e.g. banana).
• Brown –tan (after putting iodine)= simple carbohydrate; foods
with sugars usually
• Dark, blue-black (after putting iodine) = complex carbohydrate;
foods with/rich in starch and fiber
