Lesson plans

Introduce students to idea that volcanoes affect people's health




If students have access to the internet at the same time
you can allow the students a few minutes to play with the volcano erupting
this reinforces

Gas and health effects:
start with introducing the idea that the gas plume from an eruption contains gases that can affect people and animal health

Look at what the volcano in hawaii looks like
gas is usally coming out of the vent

webcam offers view from national park, updated every few minutes
you can see the visitors so you know its not the same picture
if it is black, it is night time in Hawaii, but sometimes you can see the red glow




is graphic of what is in the gas

at http://www.volcanoexperience.com/hawaii.html
is more detailed info on what is in the gas

Do people live near the volcano?
demographic map on

You can also compare whether 30 years after Mount St Helens eruption people live there
demographic map - 2010: Mt St Helen's 2000 - 2009 population

Washington state
Mt St. Helens (USA) - Washington state webcam

volcanic ash travels - Mt St Helens 1980

links to webcams for yellowstone and other volcano sites

Topics you can teach

Air Quality in Hawaii
Current Sulfur conditions

How gas plume can travel
Effect of iceland's eruption on air traffic in Europe
webcam offers what Iceland looks like near the volcano, updated every few minutes

You can show your students how chemicals make the eruption with baking soda and vinegar
includes video of collage students making large volcano eruption

Make a volcano cake.. dry ice on top for gasses

You can also talk about what is in the volcano ash and how that affects animals that eat the ash on the grass

If the survey is online, let your students fill it out, do they know that

*Some volcano gases are poisonous.

* Yes
* No

*If before going near a volcano, you have breathing problems such as asthma, bronchitis, and emphysema, could breathing in volcanic gases and ash make it worse?

* Yes
* No

*Cows and sheep that eat the grass where ash has fallen often get sick or die from fluorine in the ash.

* Yes
* No

*Volcanoes are fun to visit (geotourism) but can be dangerous.

thanks again

Choose how you want the volcano to erupt
Take our three question survey in the pop up window to tell us if you know that
Volcano gases could be poisonous,
cows and sheep that eat the grass where ash has fallen often get sick or die from flourine and people breathing in the gases or ash might have breathing problems.
Volcanos are fun to visit (geotourism) but can be dangerous.
