Overview

• Volcanoes have shaped the landscape of Arizona.
  Where is evidence of volcanoes found in Arizona?
  How did the volcanoes impact this area?

  earthquakes, volcanoes, floods, slow-wind,
  weathering
• PO 5 Identify the earth events that cause changes
  in atmospheric conditions (e.g., volcanic
  eruptions, forest fires)

5
Purpose

• In this lesson students will gain a better
  understanding of the three types of volcanoes and
  how they are formed. Students will also identify
  and locate volcanoes found throughout Arizona.
  Students will describe how volcanoes have
  impacted Arizona.

6
Materials

• Volcano transparency (label parts of volcano)
• Map of the Landform Regions of Arizona
• Key to locations of volcanoes in AZ
• Volcano Types (handout)
• Paper, pencil, and colored pencils
• Scoring Guide Types of Volcanoes

7
Objectives

• The student will be able to
• Identify the three types of volcanoes shield,
  cinder cone, and composite
• Draw each type of volcano shield, cinder cone,
  and composite
• Identify and locate volcanoes found in Arizona
• Describe how volcanoes have changed Arizona

8
Procedures

• Prerequisite Skills
• Students should be familiar with how volcanoes
  are formed and be able to identify the basic
  components of a volcano (magma chamber, vent,
  magma, and lava)
• Class Period One
• Pass out a piece of paper and have the students
  draw and label the parts of a volcano (magma
  chamber, vent, magma, and lava). Have the
  students share their picture with a partner.
• Ask the students
• Do all of the volcanoes look the same? Why or
  why not?
• What would cause the volcanoes to look different?
  (eruptions)
•  

9
Procedures

• 3. Discuss the three types of volcanoes (have
  students fill in the handouts)
•  
• 4. Explain the scoring guide. Students will now
  create their own volcanoes.

10
Procedures

• Class Period Two
•  1. Have students identify and locate volcanoes
  located in Arizona on the map of the Landform
  Regions of Arizona.
• 2. Where are most of the volcanoes found? Is
  there one area in particular or are they all over
  Arizona?

11
Procedures

• 3. Create a cause and effect diagram. When a
  volcano erupts (cause) what happens (effect)?
• the surface of the land rapidly changes as the
  lava flows and cools, holes are created in the
  earth, rocks are blasted into the air, volcanic
  lava is very hot and can destroy everything in
  its path, gases released by volcanoes can be
  poisonous.
• Positive effects the development of new crust
  on the continents, volcanic ash is blown over the
  area and increases soil fertility, groundwater
  heated by large, still-hot magma bodies can be
  tapped for geothermal energy

12
Assessments

• The students drawings will be assessed using the
  scoring guide. Mastery will be considered a
  score of 80 or higher.

13
Assessments

• Students will also answer the following question
  using complete sentences
• When a volcano erupts, what are 5 effects? Use
  complete sentences.
• Mastery will be considered correctly identifying
  4 of the 5 effects of volcanic eruptions. (must
  be written using complete sentences)

14
Extensions

• Research the most current volcanic eruption in
  Arizona. Were there people in the area? If so,
  how did it effect the people that were living in
  the area? Have students explain both the
  positive and negative effects of volcanoes.
•  

15
Extensions
Have students pretend to be a Sinagua Indian
living in the area when Sunset Crater exploded.
They would write a first hand account of what
happened that day.
16
Types of Volcanoes
Volcano is a mountain that forms when red-hot
melted rock flows through a crack onto the
earths surface. Shield are large mountains
with gentle slopes. They form from runny
lava. Cinder are small volcanoes made of
hardened lava chunks called cinders. Composite
are medium-sized mountains. They are made up of
layers of lava that alternate with layers of
cinders. These mountains have steep peaks and
gently sloping sides.
