Earthquake Lesson Plan
Topic: Earth’s Changing Surface
NSES: SCS D 1.1, 3.1
SOL: 5.7d
Daily Question: How do tectonic plates affect the Earth’s surface?
Date: November 11, 2008
Grade level: 5th
Subject: Earthquakes
Procedures for Learning Experience
Guiding Questions
Materials Needed
Engagement: Ask the children if any of
them have ever been in an earthquake. If
one of them has, ask them to describe what
it felt like. Show the earthquake video to
introduce what it is like to be in an
earthquake and the damage it can cause.
Now ask them to hold their hands up in
front of them. Put your hands together with
the palms facing each other. Push really
hard. Your hands are acting like two plates
pushing together. Keep pushing your hands
together, but now try to move one hand up
and the other down. Did you feel it when
your hands jumped to their new place?
Exploration: First, remind the students of
their discussion of tectonic plates by asking
them to recall the three different types of
faults: convergent, divergent, and
transform. Have them write their own
definition of the faults in their learning log
and then ask some children to share their
Have you ever been in an
earthquake?

definitions with the class. Now let's see
what happens when this happens on in the
Earth.
Give each student two wooden blocks, a
section of clay, and a piece of newspaper or
wax paper to work on. Have the students
put the two blocks together with the long
ends touching. Now have them press the
clay down on the paper until it is a sheet
large enough to fit over the two blocks of
wood. Put the clay on the two blocks and
push down until the clay is stuck to the
wood. Use your pencil to draw a road
across where our blocks meet (the fault).
Have the students use their blocks to make a
convergent, divergent, and transform fault.
Write down any observations you have
about the clay surface when each of these
faults occur. Have the class share their
observations with the other students at their
table (groups of 3-4). Collect all supplies
from this activity.
Divide the class into six groups (3-4
students per group). Assign each group a
different activity to test. In one group give
them a slinky and ask one person hold one
end while another person holds the other
end of the slinky while compressing a
portion. Release the compressed end and
write any observations. What happens
when the compressed portion is released?
How does that fault
behave?

they act the same?

same or different? How?

activity
In group two give them a rope and have
someone hold either end. Swing the rope
back and forth and write observations. The
next two groups will either be given a golf
ball or a ping pong ball. Drop the ball into
a container of water and write observations.
Did the ball you used sink or float? Finally
give the next two groups either a golf ball or
a ping pong ball. Drop the ball on a desk
and observe how much and how frequently
it bounces. What observations can you
make? Have the students come back
together as a class and each group share
their observations with the class.
Explanation: When the energy is released
between two plates the plates jump to their
new position, like your hands did, and cause
an earthquake. When the earthquake occurs
there are two types of waves created:
primary and secondary. Explain primary
and secondary waves in terms of the slinky
(primary) and rope (secondary) as well as
golf ball (primary) and ping pong ball
(secondary). Introduce and define the
concepts of epicenter, focus, and
seismograph (how the epicenter is
determined using readings from three
different seismographs.)
What is a primary wave?
How does it act?
What is a secondary
wave? How is it different
from a primary wave?
What is an epicenter,
focus, and seismograph?
What does a seismograph
do and how is it helpful?

10 minutes
Extension: Have the students make a
seismograph and test it. See the attached
sheet for how to set it up. Explain the
instructions to the students and have them
get in three groups and each group make a
seismograph. Use a very rough idea of
triangulation to find the epicenter of an
“earthquake” with the use of the
seismographs. How does the epicenter
change depending on the size of the reading
at each seismograph?
How does the epicenter
change when the size of
the reading changes?
Where is the epicenter in
relation to the
seismograph with the
strongest reading?

Notes: This lesson will be following a discussion of plate tectonics which will be introducing the idea of different faults. Students
should already have an understanding of convergent, divergent, and transform faults before beginning this lesson. Following this
lesson the students will enter a lesson about volcanoes and their relation to plate tectonics as well. In terms of safety notes, it may be
beneficial to have students wear goggles when completing the group activities with the slinky, rope, golf ball, and ping pong ball since
some of those items could be harmful if the proper procedures are not followed.
