Phet virtual Lab

●Claim(Greenhouse gases absorb radiated heat bounced off of the planet
Earth.

●Evidence: This lab is a virtual interaction with greenhouse molecule
simulation for radiation passing through it

●Reasoning: What do you think the reasoning is?

Which one do you think it is?

Things to think about

Greenhouse gases absorb infrared radiation emitted from the Earth's surface, which is essentially heat energy, trapping it within the atmosphere and contributing to the greenhouse effect

CAMERA POLICY

Teachers will send a private message then verbal warning if a student’s camera is not on.
Continued non-camera use will result in moving up the discipline ladder.

First offense: Teacher conferences with student and documents in IC.

Second offense: Teacher conferences with student, contacts LC and documents in IC.

Third offense: Teacher conferences with student, contacts LC, sends over to academic
coach for support and documents in IC.

Fourth offense: Academic coach submits discipline referral to discipline AP

Please make sure to turn your camera on at the beginning of each class.

You can set it to private (only teacher sees) or public (everyone sees).

Goal

• For example, for most of the

questions and responses if we get
a 80% or higher participation rate.
We will get a class party Next
week. We can have a little 5-
minute release today too
Class party let’s make this our

class and be victorious!

Standards

SEV2. Obtain, evaluate, and communicate
information to construct explanations of
stability and change in Earth’s ecosystems.

b. Analyze and interpret data to determine
how changes in atmospheric chemistry
(carbon dioxide and methane) impact the
greenhouse effect.

Learning Target

I can identify the impact of greenhouse
gas output from human impacts

I can identify the effect for inverse
ozone layer.

Essential Question

The global warming is caused by an
increase of greenhouse gases in the
atmosphere. So does nature ever have
an increase in greenhouse gases and has
this happened in the history of the
planet?

Important Vocabulary


Ozone Layer
the region of Earth's stratosphere that absorbs most of the Sun's harmful ultraviolet radiation, protecting living organisms from radiation damage.

Greenhouse Gas
a gas that contributes to the greenhouse effect by trapping heat in the atmosphere, including carbon dioxide, methane, and nitrous oxide.

Ozone Inversion
a phenomenon where a layer of ozone in the atmosphere traps cold air near the ground, preventing it from rising, which can lead to air quality issues.

Vostok Ice
ice cores retrieved from the Vostok Station in Antarctica, which provide valuable data about past climate conditions and atmospheric composition over hundreds of thousands of years.

Ice Age
a prolonged period of time during which significant portions of the Earth's surface were covered by ice sheets and glaciers, profoundly affecting the planet's climate and ecosystems.

Analyzing and Interpreting Data

●However, ice cores have
provided us with evidence
that abrupt changes are
also possible. During the
last glacial period,
Greenland experienced a
sequence of very fast
warmings (see Fig. 5). The
temperature increased by
more than 10°C within a
few decades.

What if we were to discover tomorrow that a climate
catastrophe was imminent if our planet warmed any further?
To reduce emissions enough to avoid this catastrophe, we
would have to cut them close to zero — and right away," says
Caldeira.

Human industrial revolution has
brought other problems too

●
Over time, a number of institutions have
taken measures to counter the greenhouse
effect derived from harmful gas emissions:
before the Kyoto protocol we had
the Montreal Protocol (1987), which
established the terms within which the
signatories had to contain the production
and consumption of substances that are
harmful for stratospheric ozone. These
include halon, carbon tetrachloride,
chlorofluorocarbons,
hydrochlorofluorocarbons, trichloroethane,
methyl chloroform, methyl bromide, and
bromochloromethane.

Brain Break

What else add to greenhouse gases?

Can you think of anything else that adds to greenhouse gas emissions?

Answer in chat, on the mic, or add pictures to the whiteboard.

Following are some things that you might not have thought about.

Pick something you

have.

What are doing that reduces greenhouse gas use?

.

Are you here?

Yes

I am working on it

Lesson Summary

➢ Greenhouse gases are increasing in

the atmosphere.

➢ Many of them are added by things

that we do and use everyday.

➢ These extra gases are like an extra

blanket around the earth making it
hotter.

Human Impact

The Impact of Global Warming

Global warming is a serious environmental
issue that occurs when certain gases,
known as greenhouse gases, accumulate in the Earth’s
atmosphere. These gases, such as carbon dioxide
and methane, trap heat from the sun, preventing
it from escaping back into space. As a result,
the average temperature of the planet increases,
leading to various consequences like rising
sea levels and more extreme weather patterns.
This trapping of heat is a major factor in
climate change, affecting ecosystems
and human communities around the world.
It is crucial for us to understand and address
the sources of greenhouse gases to mitigate
the effects of global warming and protect
our planet for future generations.

Greenhouse gas emissions don't just
come from airplanes, factories and coal
power stations. Our environmental
footprint is spread across a huge range
of everyday goods, from the videos we
watch online to the water we drink.

The fashion industry is responsible for
about 10% of global greenhouse
emissions. It consumes more energy
than aviation and shipping industries
combined. Most of those emissions
come from its long supply chains and
energy-intensive production --
especially the dyeing and finishing
process.
