This document provides information about macromolecules and their structure and function. It begins by stating the learning objectives of determining the structure and functions of biomolecules. It then defines macromolecules as large organic compounds formed from monomers joining together to create polymers. The four main types of macromolecules - carbohydrates, lipids, proteins, and nucleic acids - are introduced along with their monomer and polymer subunits. Specific examples and functions of each macromolecule type are then described in more detail over several pages.
Description
This infographic presents the theories that have been formulated about the structure of the atom. Each theory is accompanied with a basic description and a comparison is sought between them.
Objectives
After the completion of this lesson, students will be able to:
- Understand the differences between the pre-quantum and quantum theories.
- Understand the experimental data that led to the progress of the theories.
- Describe the structural components of matter as well as their properties.
Activities
1. Democritus’ theory: Students have to think about how small matter can get, to understand the meaning of the word ‘atomos’ and to understand that this specific theory was impossible to prove.
2. Dalton’s theory: Students have to discuss the reason that Dalton is considered as the father of the atomic theory despite the fact that Democritus had the original idea.
3. Thomson’s theory: The teacher introduces the discovery of electrons and challenges students to consider the structure of plum pudding in order to explain the specific theory.
4. Rutherford’s model: The teacher asks students to enlarge the atom to the size of football court in order to understand that the nucleus will be the size of a ping-pong ball. The students watch the animated video of Rutherford’s model.
5. Bohr’s model: Students have to observe images of the last two models and discuss the similarities and differences. Students have to explore the structure of different atoms through the simulation link.
6. Quantum Mechanical model: The teacher asks students to observe specific images with different meanings in order to introduce the double nature of an electron. Students have to understand that electrons exist as ‘probability clouds.’

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.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

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.

1. LEARNING OBJECTIVE:
• Determine the structure and
functions of biomolecules
• Determine their properties and
functions
MA.SUZANNE HIZOLE-
REGAÑON 2023
3. What is organic chemistry?
Organic Chemistry is the study of compounds
that contain bonds with carbon atoms.
All living things contain the element carbon.
4. What’s The big Deal About Carbon?
No other element comes close to matching
carbon’s versatility!
These Mighty Atoms:
• Can form millions of different large and
complex structures.
• Easily Bond with elements and each other
• Can form chains and rings.
• Can form single, double, or triple bonds
Benzene
5. Macromolecules
AKA Organic molecules or biomolecules
Macromolecules are large organic compounds formed from hundreds
or thousands of smaller molecules.
• Small molecules that join together are monomers. (mono means
“one”). Monomers are like links in a chain.
• When monomers join together they form long polymers. (poly
means “many). Polymers are chains of monomers.
6. Polymers
Think of polymers as a beaded necklace. Like the different beads on
this necklace, polymers can be made from different monomers.
How many different “monomers” make up this necklace?

7. What are the groups of
macromolecules?
Macromolecules in living things are
grouped based on their chemical
compositions
4 Main Macromolecules are:
• Carbohydrates
• Lipids
• Proteins
• Nucleic Acids
8. CARBOHYDRATES!
AKA: Sugars and Starches
Usually colorless, water soluble, and
crystalized.
Composed of: Carbon, Hydrogen, and
Oxygen Atoms (CHO)
Monomer: Monosaccharaides
Polymer: Disaccharides and
Polysaccharides
9. CARBOHYDRATES!
Carbohydrates are classified in groups
based on number of different molecules.
1 Molecule - Monosaccharaide
2 Molecules - Disaccharides
3 or More Molecules – Polysaccharides
10. Functions of CARBOHYDRATES
1. Readily Available Source of
Short Term Energy. QUICK!
2. Energy Storage
• Glycogen stores energy in animals
-liver and muscle cells
• Starch stores energy in plants
3. Structural
Cell Walls in Bacteria and Plants
Exoskeletons of Insects, Arthropods, and Crustaceans.
15. Polysaccharide Carbohydrates
AKA: Complex Carbohydrates
What does “poly” mean?
Examples:
• Glycogen: Energy storage in animals.
• Starch: Energy storage in plants
• Cellulose: Builds cell walls for plants
16. Lipids!
AKA: Fats, Oils, and Waxes
Composed of: Carbon, Hydrogen, and Oxygen atoms (CHO)
Monomer: Fatty Acids & Glycerol
Polymer: Fats, Oils, Waxes
Functions:
• Stores Energy in Long Term
• Make Up Cell Membranes
• Steroids
Examples:
• Fats & Oils: Energy Storage
• Waxes: Repel Water
• Steroids: Cholesterol, Sex Hormones, and Cortisol (stress hormone;natural flight or fight
response)
• Phospholipid Cell Membranes: Protect and Regulate Cell Homeostasis
**Lipids are generally NOT soluble in water.**
17. Kinds of fats:
1. Saturated fats have two carbons attached to each carbon
(except the one at the end). Saturated fats are unhealthy
fats like butter.
2. Unsaturated fats are missing at least one hydrogen and are
curl in shape. The unsaturated fats are healthy, and include
oils.
3. Trans fat are usually listed as ‘hydrogenated fats’ or
‘hydrogenated vegetable oils’ in the ingredients. It give
foods a desirable taste and texture. Many restaurants and
fast-food outlets use trans fats to deep-fry foods because
oils with trans fats can be used many times
19. Polymer:
Phospholipids
• Make up cell
membranes.
• Phospholipids pair up
to create a protective
phospholipid bilayer.

20. Proteins
The Most Diverse
Macromolecule Group
Composed of: Carbon, Hydrogen,
Oxygen, and Nitrogen Atoms (CHON)
Monomer: Amino Acids
Polymer: Polypeptide
Functions:
• Form Cell Structures
• Transport Substances In and Out of
Cells
• Enzymes control the rate of reactions

• Defense Against Disease (antibodies)
All Amino Acids
Contain an Amino
Group & Carboxyl
Group
Enzymes Control
Reaction Rates
21. Protein structure and function
Amino acids link together to form a polypeptide.
About 20 Amino Acids are found in nature.
A protein is built from one or more polypeptides.
Formed by RNA
22. Examples of proteins and their functions are:
1. Keratin is a structural protein found in hair, skin, and
nails.
2. Fibroin / Silk protein - Fibroin is found in silk. Silk has a
smooth and soft texture. It is one of the strongest natural
fibers that have high resistance to deformation. It is also a
good insulating material.
3. Collagen is a major insoluble fibrous protein found in
connective tissues such as tendons, ligaments, skin,
cartilage and the cornea of the eye. It comprises as much
as 30% of proteins in animals.
23. 4. Enzymes function to catalyze chemical reactions.
They either speed up a reaction, lower the needed
energy for a reaction to take place, or bind substances
to their specific partners. Examples of enzymes
a. Lipase - help in digestion of fats
b. b. Pepsin - help in breaking down proteins into
peptides (smaller units)
c. c. Sucrase - also called invertase; help in the
digestion of sugars and starches
