Brief
Description of Lesson I:
In this lesson, students will develop a basic understanding of volcanoes.
Students will also watch a PowerPoint Presentation to learn about volcanoes.
Duration:
Approximately
2 60-minute class periods
Content
Standards Used/Unit Goals/Objectives Supported:
ESS-M-A3 investigating the characteristics of volcanoes and
identifying zones where they may occur
Lesson
Goals:
Students
will identify and compare three types of volcanoes.
Lesson
Objectives:
TLW
understand that there are three types of volcanoes: shield volcanoes, cinder
cones, and composite volcanoes.
TLW
understand what each type of volcano produces when it erupts.
TLW
understand that each type of volcano has a distinct shape.
Resources
Computers
and Internet access for all students
Procedures:
1.
Review
with students what they already know about volcanoes.
2.
Have
students use research materials you have provided or the Internet to find a
description and pictures of shield, cinder cones, and composite volcanoes.
-
A shield volcano is formed when a large amount of
free-flowing lava, or molten rock, spills from a vent, or opening in the earth,
and spreads widely. The lava gradually builds up a low, broad, dome-shaped
mountain.
-
A
cinder cone builds up when mostly ash erupts from a vent and falls to the earth
around the vent. The accumulated ash forms a cone-shaped mountain that appears
flat on top.
-
A
composite volcano is formed when both lava and ash erupt from a vent. The
materials pile up in alternate layers around the vent and form a cone-shaped
mountain that comes to a point on top.
3.
Students will view PowerPoint explaining procedure
for creating volcano model. Record notes in logbook.
4.
Divide
class into groups to create a model volcano.
5.
Students
will view compressed video to gain direction on erupting their model volcano.
Record notes in logbook.
6.
Students
will erupt their model volcanoes using baking soda, vinegar, and food coloring.
