TOO HOT TO
HANDLE- VOLCANOES
MASTER
TEACHER: Theresa Hoggard
Grade
Level:
5-6
Time Allotment: Two
45-minute class periods
Overview: Earth’s plates collide, pull apart, and slide
past each other. Most mountains and
volcanoes form at plate boundaries. Many
earthquakes also occur at plate boundaries.
A volcano is a mountain formed by lava and ash.
Lava is magma that reaches Earth’s surface.
Ash is small pieces of hardened lava.
Chains of volcanoes form where a continental plate and an oceanic plate
collide. The edge of the oceanic plate pushes under the edge of the
continental plate. The leading edge
of the oceanic plate melts as it sinks deep into the mantle.
The melted rock becomes magma that forces its way up between the plates.
In this
lesson, the students will observe the causes and effects of volcanic eruptions.
The students will use real time data to chart the exact location of the
most recent volcanic eruptions. They
will use latitude and longitude to graph coordinates all around the world.

Materials:
For each
student:
World map
Different
igneous rocks- basalt, tuff, pumice
Pen or
pencil
Dry erase
board (if using laminated world maps)
Prep
for Teachers:
Prior to
teaching the lesson, bookmark all Web sites which will be used. Load any plug-ins necessary to run the Web sites.
Install CD ROM. Cue the videotape to the appropriate starting point.
Introductory
Activity: Setting the Stage
The
following activity will prepare your students for a lesson on volcanoes, and
provide them with context for the causes of volcanic eruptions.
Step
1.
Review plate
tectonics. Show CD-ROM.
Step
2.
Pass around
different types of igneous rocks. Igneous
rocks can vary in size, shape, mass, and texture.
Ask them to describe the rock to a partner. They should observe that igneous rocks vary in color and
mass. Pumice is very light and
porous. Tuff is also very light in
mass but not as porous as pumice. Basalt,
on the other hand, is very dark in color and very dense. Tell students that the intensity of the volcanic eruption
determines the rock type.
Step
3.
Next, show
students pictures of the three types of volcanoes.
Shield volcanoes are broad
volcanoes with gentle slopes and are mostly lava. Cinder cone volcanoes
are tall and narrow, with steep slopes and are mostly ash.
Composite volcanoes are wide
and have fairly steep slopes. They are lava and ash.
Learning
Activity
Step
1.
Explain to
students that they will now be witnessing a volcanic eruption through a video.
They will view the effects of a volcanic eruption and draw conclusions
about the causes of volcanic formations. Provide
students with a Focus for Media Interaction by asking them for the locations of
volcanic activity visited and presented in the video. Also have the students infer what type of volcano they are
seeing in the video.
Step
2.
Insert
Too Hot to Handle video
BEGIN
viewing tape at the beginning. PAUSE after Lisa says, “Are you ready, Robin?”
“Ready.”
Ask students why it would be hotter near the vent.
(It is where the lava is seeping out of the crust.)
Ask students to estimate how hot it would be near the vent.
(Thousands of degrees Celsius) Activate
prior knowledge by asking, "What is the boiling point of water?"
Ask students the location of the volcano.
RESUME
video. PAUSE
when helicopter flies off. Have
students turn to a partner and tell about the purpose of taking samples.
(To find the age of the rock)
RESUME video.
PAUSE when background music
stops and is the end of the volcano footage.
Ask students how the volcano has changed. Now ask what it has produced.
(land)
End of Video
Ask students
to make a list of 10 facts learned from the video.
END OF CLASS
ONE
Learning Activities
Step
1.
Review facts
and details learned from yesterday’s video.
Step
2.
Students
tell a partner the locations of volcanoes visited in yesterday’s video.
Culminating
Activity
In order to
help students explore the locations of volcanic eruptions in the last few
months, try this activity involving graphing of coordinates that show volcanic
eruptions around the world.
Step
1.
Distribute
individual world maps- either laminated ones for use with white board markers or
consumable desk maps. Tell students
that today they will be learning about locations of active volcanoes around the
world. Review graphing coordinate
points with students. Remind them
that the first number is always the latitude and the second number is always the
longitude. Remind students about
the compass rose. (North, South, East, and West)
Step
2.
Log on to http://volcano.und.nodak.edu/vwdocs/current_volcs/current.html
Explain the picture first seen on the web page. It is a picture of Mt. St. Helen’s explosive eruption in
May 1980. Explain to them that we
will be tracking volcanic eruptions around the world as they erupt.
The following web page tells of the location, coordinates, and date of
last volcanic eruption.
Step
3.
Model
graphing coordinate points. Ask
students to locate the last 10 volcanic eruptions around the world by marking on
their world map. Ask students
to draw conclusions and infer where most volcanic eruptions occur.
(near plate boundaries)
Step
4.
Bring
closure to lesson by giving students information about volcanic islands.
Many islands in the oceans are actually tops of volcanic mountains.
Hawaii is part of a 3,000-mile chain that extends from Alaska. The oldest member is near Alaska and was formed 700 million
years ago. The island of Hawaii is
the youngest one at one million years. The
chain formed because a narrow plume of magma burst through the crust, and while
the plume remained stationary, the plate moved, forming a chain of mountains.
In this chain, only the island of Hawaii, which is directly above the hot
spot, has active volcanoes.
Cross-Curricular
Extensions
READING
Identify
Cause and Effect: Make a cause-and-effect chart on a sheet of notebook paper.
Write the causes and have students write the effects to complete the
chart.
Provide more
depth with trade books. These books
contain information about changes in Earth’s surface. Volcano: The Eruption and
Healing of Mount St. Helens by Patricia Lauber; The Secrets of Vesuvius by Sara C. Bisel
SOCIAL
STUDIES
Archaelogy:
In A.D. 79 the city of Pompeii, Italy was destroyed by the eruption of
Mount Vesuvius. The ash from the
volcano combined with rain, and this substance sealed the entire town.
Homes, shops, theatres, and other building were preserved intact, as well
as the skeletons of the victims. Ask
students to research life in Pompeii in A.D. 79 and present the information to
the class.
VISUAL ART
Volcanic
Display: Challenge students to make a display of models and/ or drawings of the
different types of volcanoes and eruptions.
Community
Connections
·
Contact a
local geologist and arrange for a visit to the classroom to discuss other
destructive or constructive forces that change the features of the land.
·
Contact the
United States Geological Society and arrange for a USGS representative to visit
your classroom to discuss qualifications and requirements that are needed to
become a volcanologist.
Student
Materials
Individual
copies of world maps. They may be
laminated maps where they can use white board markers and be able to erase; or
use consumable world maps.
