Science 3: Volcanic Activity in the Modern World
We hope you lava learning about melting rocks and eruptions, because today we're learning all about volcanoes.
|Elementary and Middle School||3rd Grade|
Nope, we're talking about the very first, original Ring of Fire: a chain of volcanoes
around the Pacific Ocean.
So…yeah, it's just a tad older than hula hoops are… [The ring of fire location shown on a map]
And believe it or not, many of those volcanoes are still active to this day… [Volcano erupting]
…Probably because of a healthy diet and regular exercise. [Box of Wheaties on a rock]
The Ring of Fire contains 452 total volcanoes – which is over 75% of the total volcanoes
in the world, and includes volcanoes in...
Bolivia, Chile, Peru, Ecuador, Guatemala, Mexico, Costa Rica, [The locations shown on a map]
Russia, Japan, The Philippines, Indonesia, New Zealand, Antarctica, Canada, and
That was exhausting.
And if you've ever visited the great state of Washington, you may have seen one of these
beauties in person!
But don't worry.
Mount Saint Helens last erupted in…2008…? [Kids walking to Mount St. Helens]
Actually, that's…not super reassuring. [They run away]
And before that, it erupted on May 18th, 1980.
Here's what it looked like before…
Here's what it looked like during the eruption.
Pretty freaky, huh?
And finally, here's what it looked like afterwards.
Even worse than your living room after the time your little sister accidentally drank [Sisters kicks the TV over and jumps out the window]
What a day.
As you can probably tell, this eruption was no joke.
It caused over a billion dollars in damage, and tragically lost the lives of 57 people. [Newspaper article about the eruption]
Hawaii is another state within the Ring of Fire, and is currently home to several active
volcanoes, including Kilauea, Mauna Loa , and Loihi
Naturally, active volcanoes can cause problems wherever they are, and Hawaii is no different. [People at the beach]
After all, it's hard to enjoy your tropical paradise when lava is flowing from these volcanoes,
destroying roads and buildings. [Videos of volcano damage]
But on the islands of Hawaii, this lava also serves a positive purpose: when it flows into
the surrounding water, it cools down and turns into solid rock, effectively creating new
land and expanding the islands.
And hey, Hawaii is pretty beautiful!
Who could complain about having more of a good thing?
What's more, the volcanoes in Hawaii provide geothermal energy. [Coop pointing at a blackboard]
Geothermal energy is energy provided by heat from the earth – and it's both clean and
For all the destruction volcanoes can do, they sure can be useful.
So if there's one lesson to be learned from volcanoes, it's that while something might [People watching an eruption]
appear totally dangerous and destructive on the surface, it actually might have some surprising [Teddy bear flies out of an erupting volcano]
Try to remember that the next time your little sister forgets to get decaf and is destroying
