Electrical charges can build up on objects when they are rubbed together. This document discusses electricity, magnetism, and energy. It defines electricity as the flow of electrical charges and describes how materials can be conductors or insulators. Magnets attract other magnetic materials and have north and south poles that can attract or repel each other. There are different forms of energy including chemical, light, mechanical, thermal, and electrical. Energy sources can be renewable, like the sun, wind, water, and biomass, or non-renewable, like fossil fuels and nuclear fuels.
Introductory pre-college physics class to introduce the subject of atoms, isotopes, ions, energy (kinetic/potential/radiative) and light. This class would be followed by exercises and applications with light and energy, and laws of motion/forces.

By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
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.

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. Electrical charges
When we rub a pen against a wool jumper
and then hold the pen near some small
pieces of paper, the pieces will stand up
and stick to the pen.
This happens because of electrical
charges. The pen becomes electrically
charged when it is rubbed against
something. Then, it is able to attract small
objects.
All objects around us, such as your body
or the stars, have electrical charges.

4. Electric current
An electric current is the flow of electrical charges
through materials. When more electrical charges
circulate, the electric current is stronger and more
electricity flows. Electricity carried in an electric
current can easily be transformed in other forms of
energy.
5. Materials can be classiified into two types,
depending on how easily electrical charges can flow
through them.
Conductors. These are materials that allow
electrical charges to move freely. For this reason,
electric current flows easily through them. Copper,
silver and other metals are good conductors.
Insulators. These are materials that do not allow
electrical charges to move. Therefore, electric
current does not flow through them. Glass, plastic
and most non- metal materials are good
insulators.
Conductors and insulators
6. Electric current produce many different effects when
flowing through objects: heat, light, sound, magnetism,
movement and chemical effects. Match the following
objects to their corresponding effects:
a tablet screen an oven a doorbell
a mobile battery a blender (batidora)
Now it’s your turn!

8. MAGNETS
A magnet is an object which attracts other
objects made of iron and other magnetic
metals. We call this attraction magnetism.
Magnets can be natural or artificial. Some
minerals, like magnetite, attract metallic
objects. These are natural magnets.
However, almost all of the magnets we
use are artificial magnets, which are
made of magnetic metals.
9. Magnetic forces
All magnets have two areas,
called poles.
These areas are known as the
north magnetic pole (N)
and the south magnetic pole (S).
Magnetic forces can act at a
distance. When we put two
magnets next to each other, they
can attract or they can repel
each other.
10. When we place
opposite poles
of magnets near
each other,
they attract.
When we place
same poles
of magnets near
each other,
they repel.
11. Draw a diagram showing magnetic forces.
Now it’s your turn!

13. ENERGY
Energy is the ability to do work or cause
changes. When energy is not at work, it is
stored as the potential to do work. For
example, food has stored energy. When
living things eat, they get energy from
food.
14. Energy can exist in different forms.
Forms of energy
Chemical energy is
stored in food, plants,
batteries, fuel and
explosives.
light energy is
emited by light sources,
such as stars, light
bulbs or candles.
15. mechanical energy
is the energy of an
object due to its motion
and position.
thermal energy is
released by objects as
heat. The higher the
temperature of an
object, the greater is
thermal energy.
16. electrical energy is
produced by the
movement of charged
particles. It can be
easily transformed into
other forms of energy,
such as thermal energy
or light energy.
17. Energy sources
Energy sources are the natural resources
from which energy is obtained.
Energy from many different energy
sources is transformed into electrical
energy.
Energy sources can be renewable or
non- renewable.
18. Renewable energy sources
They will never run out. These are
the main renewable energy sources
that can be transformed into
electrical energy:
- The Sun emits energy as light and
heat.
- Wind has mechanical energy. Wind
turbines transform mechanical
energy.
- Flowing water has mechanical
energy, known as hydraulic energy.
18
19. - Flowing water has mechanical
energy, known as hydraulic energy.
- The Earth’s internal heat is thermal
energy, known as geothermal
energy.
- Biomass is biological material from
plants and animals. Biomass has
chemical energy.
19
20. Non- renewable energy sources
Non-renewable energy sources will
run out one day.
There are two main types:
- Fossil fuels include coal, petroleum
and natural gas.
- Nuclear fuels include uranium and
plutonium.

21. 1. Make a list with advantages and disadvantages of
electric cars.
2. Explain the difference between renewable and non-
renewable energy sources.
