14 chemical effects of electric currentCHEKIT SHARMA
this is the best chapter in science as it is my favioratie as i love chemistry and even i think that the people who would view this will like so i request to plese like share and comment so ok today only this much is enough so i'll leave bye
This is a PowerPoint presentation based on air pollution. Most of the points are taken from class 8 science textbook. The slides are from slidescarnival.com(keyword- air pollution). This is definitely not the best but I hope it helps:) Also, we had a little ending speech at the end and a thank you slide without a conclusion would be awkward^

Garbage In, Garbage Out: Optimizing Design Inputs for Successful PrototypesKamaria Campbell
We’ve all heard the phrase “Garbage in, Garbage out”. The quality of a product or service is often linked to the quality of the underlying components. When it comes to prototypes, the truth is that much of the important work happens before we ever create a prototype artifact. This may include brainstorm sessions, creating requirements documents, analyzing an existing system, etc. More often than not, the effectiveness of the prototype is linked to how effectively these different aspects are managed in the pre-design process. Whether you are a designer, business representative, project manager or developer, this session will provide you with effective techniques for managing design inputs to create better prototypes.

A Strategic Approach: GenAI in EducationPeter 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.

2. What is air ?
Air is the Earth's atmosphere.
Air around us is a mixture of many gases and dust particles. It is
the clear gas in which living things live and breathe.
It has an indefinite shape and volume. It has no color or smell. It
has mass and weight.
It is a matter as it has mass and weight. Air creates atmospheric
pressure. There is no air in the vacuum of the cosmos.
3. Atmosphere
The layer of air surrounding the earth is called the atmosphere.
There are 5 layers of the Atmosphere.
They are Exosphere, Thermosphere, Mesosphere,Stratosphere
& Troposphere
4. Composition Of Air
Until the eighteenth century, people thought air was just one
substance.
Experiments have proved that it is really not so.
Air is a mixture of many gases.
Let us find out about some of the major components of this
mixture,one by one.
5. Nitrogen
It is the major component of air.
Unlike Oxygen, it does not support burning, instead it extinguishes
it.
It takes up nearly 78% or 4/5ths of the air.
6. Oxygen
1. fix two small candles of the same size in the middle of two shallow containers.
2. Now, fill the containers with some water. Light the candles and then cover each one
of them with an inverted glass (one much taller than the other) Observe carefully
what happens to the burning candles and the water level.
Do the candles continue to burn or go off? Does the level of water inside glasses
remain the same?
The burning of the candle must be due to presence of some component of air, isn’t
it? Do you find any difference in your observation with the two glasses of different
heights? What can be the reason for this?
Burning can occur only in the presence of oxygen. We see that, one component of
air is oxygen.
7. Carbon Dioxide
Carbon dioxide makes up a small component of the air around us.
Plants and animals consume oxygen for respiration and produce
carbon dioxide.
Plant and animal matter on burning, also consumes oxygen and
produces mainly carbon dioxide and a few other gases.
8. Water Vapour
We have learnt earlier that air contains water vapour.
We also saw that, when air comes in contact with a cool surface, it
condenses and drops of water appear on the cooled surfaces.
The presence of water vapour in air is important for the water cycle
in nature
9. Dust & Smoke
The burning of fuel also produces smoke.
Smoke contains a few gases and fine dust particles and is often
harmful. That is why you see long chimneys in factories.
This takes the harmful smoke and gases away from our noses, but,
brings it closer to the birds flying up in the sky!
Dust particles are always present in air.
10. Experiment- To prove dust is present in
air
Find a sunny room in your school/ home.
Close all the doors and windows with curtains pulled down to make
the room dark. Now, open the door or a window facing the sun, just
a little, in such a way that it allows sunlight to enter the room only
through a slit.
Look carefully at the incoming beam of sunlight.Do you see some
tiny shining particles moving in the beam of sunlight,what are these
particles? This experiment shows that air also contains dust
particles.
11. Properties Of Air
Important properties of air are:
1) Air occupies space
2) Air is present everywhere including water and soil
3) Air is transparent
4) Air is colourless
5) Air is essential for life on earth
12. Recipe Of Air
1. Recipe of air…
- 79 cups of nitrogen molecules
- 20 cups of oxygen molecules
- 1 cup of argon atoms
- A dash of other gases, including water vapor and carbon dioxide.
Mix all the ingredients together.
The result will be a colorless, odorless, and tasteless gas with a density about 800 times less than
water. This means that walking along the beach, you have over 1000 pounds (450 kg) of air
above your head and shoulders, and the air in the average high school gym weighs over three
tons!
2. Breathing the air in Mumbai for ONE day is equivalent to smoking 2.5 packs of cigarettes.
3. All that extra air in potato chip packs we complain about is actually Nitrogen and serves a purpose.
It preserves the crispiness and provides cushion during shipping.
