Youth Curriculum

1. ENVIRONMENTAL
SCIENCE!

2. POP QUIZ TIME
• What does the symbol for a resistor look
like? You can say it in words.
• What is thermodynamics?
• What is electricity?

3. ENVIRONMENTAL SCIENCES (REVIEW)
• What is environmental
sciences?
Well, we will talk about how
hoomans (cat spelling) have
impacted the world.
• An easy example is
buildings.
1. When dug up the
materials needed
2. Cleared a place to build
3. Built a building

4. WHAT ARE THEY AND WHY ARE THEY BAD?
GREEN HOUSE GASES
• Gases that trap heat in the atmosphere
are greenhouse gases.
They let sunlight pass through the
atmosphere, but they prevent the heat
that the sunlight brings from leaving the
atmosphere.
• They get their name from greenhouses.
A greenhouse is full of windows that let
in sunlight. That sunlight creates
warmth. The big trick of a greenhouse is
that it doesn’t let that warmth escape.

5. GREENHOUSE GASES
• Overall, greenhouse gases are a
good thing.
• Without them, our planet would
be too cold, and life as we know
it would not exist.
• But there can be too much of a
good thing.
• Scientists are worried that human
activities are adding too much of
these gases to the atmosphere.

6. THE HEATING OF THE EARTH IMPACTS MANY
DIFFERENT THINGS!!!

7. GREENLAND’S MELTING ICE
Because temperatures are higher than normal,
Greenland’s ice is melting and raising sea levels.

8. HOT HOT SUMMERS
• Last year’s summer was so warm
• 600 billion tons of ice melted from Greenland – enough to raise
global sea levels by 2.2 mm in just two months, new research has
found.

9. BLUE WHALE SCIENCE
Just so you can picture this:
A blue whale weighs 115 tons.
The amount out melted ice put into the ocean by rising sea levels
is equal to the weight of 5,217,391,304 blue whales (over 5 billion
blue whales)

10. WOW. JUST WOW
• The ice that melted into the ocean is the weight of 300 billion
Ferrari’s

11. GREENLAND’S ICE
• Because the ice is melting into the
Ocean, it raises the Earth’s sea levels.
• This can cause all those fun beaches to
flood!
• Now, this will take time to flood the
beaches like the pictures, but it will
happen

12. NO SALT WATER TAFFY…..NOOOO!
• Then, all those stores won’t be able
to sell the most delicious yummy
amazing incredible spectacular
fantastic amazing…said that already
CANDY.
• Many stores near the shore could
close down.
• So there is a domino effect
Who knows what a domino effect
is?

13. DOMINO EFFECT
Something very small (like melting ice) can have
large consequences (like no salt water taffy)

14. GREENHOUSE GASES AND GREENLAND
• The Earth can heat up because of __________
• Because the earth is heating up it can _________ from Greenland.
• Because the _________ melts from Greenland,
the beaches will __________.
• If the beaches ________, then, there will be no more _______ made:(

15. REMEMBER, THE BEACHES FLOODING WILL
TAKE YEARS AND YEARS AND YEARS AND
YEARS AND YEARS AND YEARS AND YEARS
AND YEARS….YOU GET THE POINT

16. ANOTHER EFFECT OF SEA LEVEL RISE
• The sea water has salt
• Hoomans cannot drink salt water
• But if the oceans rise the salt water gets into our drinking water!

17. SALT WATER INTRUSION

18. BUT PHYSICS CAN HELP!
• Remember that I said salt water is
conductive!!!!
• So, we if we create a strong current
in the water, then we can see how
much salt is in the water.
• High conductivity means a lot of
salt!
• Or, over time we can measure how
much salt water is mixing with our
fresh water!!!
This was my face when I learned this!

19. HOW DO MAGNETS MAKE AN ELECTRICAL CURRENT
• Magnets are used to make electricity.
• Moving magnetic fields pull and push electrons.
• Metals such as copper and aluminum have electrons that are
loosely held.
• Moving a magnet around a coil of wire, or moving a coil of wire
around a magnet, pushes the electrons in the wire and creates an
electrical current.
• Induced Current

20. REVIEW
• Green house gases can heat up the earth
• Heating of the earth will melt ice
• Melting ice can lead to sea level rise
• Sea level rise cause beaches flooding and salt water in our
drinking water
• Physics can help by inducing currents in the water/beaches to see
how much salt is invading the fresh drinking water
