Tsunami in a Box!
Rationale
Tsunamis are a series of ocean waves created by the sudden displacement of water by seismic
movement of the ocean oor.
Focus
How are tsunamis generated?
Do earthquakes occur underwater?
Objectives
Students will be able to:
1. Generate a tsunami and observe the results on a model shoreline.
2. Relate the analogy of the motion of the lid to the motion of the ocean oor during an
earthquake as a means of water displacement and subsequent tsunami generation.
3. Explain that not all underwater earthquakes will generate a tsunami.
Materials
Glass or metal baking pan or plastic shoe box
One liter of water
Plastic lid of the type used to re-close coffee or margarine containers
Punching tool or drawing compass
Scissors
String
Sand
Erasers, toothpicks, popsicle sticks, and other small object to represent shoreline features
Book or block of wood to serve as a wedge
Metric ruler
Procedure
1. Explain to the students:
All tsunamis are generated by a sudden displacement of water. Landslides, submarine slumps,
or earthquakes can displace water. It usually requires an earthquake with a magnitude greater
than 7 on the Richter scale to generate a signi cant tsunami. Tsunamis travel from the point
of origin at a speed of 300-350 miles an hour. Earthquake (seismic) waves travel 50 times
faster than tsunamis, thus seismographs would provide a warning of a potential tsunami within
minutes after a large earthquake occurred. This often gives time to prepare for a tsunami after
the tsunami warning has been issued.

2. Ask the students:
a. Do earthquakes occur underwater? (yes)
b. How could earthquakes under the ocean ever affect people? (Accept all reasonable answers)
c. What is a tsunami?
3. Begin the class discussion with what the students have already learned from the tsunami
curriculum.
4. Divide the students into groups, distribute materials, and give the following directions:
a. Use the wedge to tilt the box or pan at an angle of about 20 degrees.
b. Pour water into the box or pan to cover the lower end, leaving about a third of the box or pan
at the upper end dry.
c. Pack a layer of sand 2-3cm thick on the dry end of the box or pan to simulate a beach or
coastline. Use your hands to mold dunes or drifts. Draw roads parallel to the shore with a
stick or your ngers. Build docks and other small, lightweight structures to complete the shore
environment. Be creative.
d. Punch the plastic lid on one end near the rim to make a hold, and thread it with a piece of
string 20cm long. Tie knots to hold the string in place.
e. Gently (in order not to make waves) place the plastic onto the bottom at the deep end of the
box or pan. Trim to t if necessary. The string should be next to the low side of the box or
pan.
f. Have one student use several ngers to hold the plastic down tightly on the shallow end, while
another student pulls the string up at the deep end with a rapid movement. Tsunami!
Conclusion
Ask the students:
1. What does the sudden motion of the lid represent? (The sudden motion of the ocean oor.)
2. Using the lid as an analogy, explain that like the lid, a sudden release of energy as the upward
motion of the ocean oor literally pushes the water away in the form of waves, thus a tsunami.
3. Remember that not all earthquakes generate tsunamis, only those that signi cantly displace the
ocean oor.
Construction:
1. Place the clean, empty bottle on the baking pan
Volcano Erupting!
This project simulates a volcano when it erupts. Using basic household equipment and food products
(vinegar and baking soda), combining the liquid mixture will produce carbon dioxide gas. That
chemical reaction will in turn produce a bubbly foam that spews out of the bottle. Because the foaming
action can be messy, you may want to perform the last step while out-of-doors, or on a large table that
is completely covered with newspaper.
Supplies:
• Lots of newspaper
• A large aluminum baking pan
• Baking soda (about 3-4 tablespoons)
• Vinegar (about1/2 cup)
• Liquid dishwashing soap
• Small plastic bottle (pop bottle size)
• Modeling clay
• Funnel
• Measuring spoons and cup
• Red food coloring
• Twigs and small plant branches
• Small amount of silver glitter
The Eruption!
• Use the funnel to pour the vinegar mixture into the bottle, and
quickly remove the funnel.
• Your volcano will erupt immediately!
4. Using the clean, dry funnel, pour 3 or 4 tablespoons of baking
soda into the bottle. Then add a few drops of dishwashing
detergent, the water, and a teaspoon of glitter.
5. In a separate container, mix a few drops of red food coloring into
the vinegar.
2. Mold the modeling clay around the bottle to appear like a
mountain — large at the bottom, building up towards the top of
the bottle. Keep the top of the bottle clean, and don’t let any clay
fall inside the bottle.
3. Decorate the bottle to look like a mountain. Use small plant
branches to represent trees.
