2. Define Seismic wave.
Activity No.
Investigating Earthquake Waves
Materials:
1 basin or large container
Styrofoam
String
ENGAGE Question: How do earthquakes travel in the earth?
Hypothesis:
Procedure A. Construction of house Model.
1. Using a Styrofoam create two (2) miniature house models.
Make sure that the base is balance when it is placed
in the water.
2. At the bottom part of the miniature house insert the
String with a nail attached at one end.
ANALYSIS:
2pcs-nails
Procedure B. Creating water waves.
1. Fill the basin/container with water.
2. When the water at the container/basin is steady place
the miniature houses with at least 15 cm
away from each other.
3. Ask one member of the group to vigorously
Tap the right side of the container until
Continuous ripples are created in the water.
4. observe the movement of the house and the
nails.
movement of the house and m
CONCLUSION
Not for sale
Observation:
1. What causes the movement of the houses?
2. In this set-up, tell what each part represents:
a. The basin and the water.
b. The houses:
c. The part of the basin where you tap.
3.
ifferentiate the movement of the house to the movement of the nails.
4. Is the shaking the same at both houses? How intensity does vary from
the distance to the focus?
