Mechanisms of Movement Lab Report
Problem:
What happens to the asthenosphere as lithospheric plates move at the three types of plate
boundaries?
Hypothesis:
Review the virtual lab demonstration in the lesson and stop the video when prompted to
formulate a hypothesis. Hypothesize what will happen to the “plates” outside of your egg when
you move them towards, away from, and past one another.
If the “plates” move towards
each other then they'll form a mountain
.
If the “plates” move away
from each other then they'll form holes like trenches
.
If the “plates” move past
each other then they'll keep going
.
Materials:
Watch the virtual lab demonstration video within the lesson. No additional materials are
needed.
Optional
:
If you wish to perform the lab in the video demonstration, the materials are listed
below.
●
water
●
pan
●
raw egg
●
cracking device such as a teaspoon
●
paper towels or newspaper
Procedures:
1.
Watch the Tectonic Egg Virtual Lab Demonstration Video within the lesson and record
your observations in Table 1.
2.
Complete the Questions and Conclusion section of the lab report.
Optional Procedures.
1.
If you would like to perform the lab in the video demonstration, perform steps 2
through 8 under adult supervision.
2.
Boil an egg until all parts are cooked (about 10 minutes).
3.
Pour the water off and allow the egg to cool. You can put the egg in cold water to
cool it more quickly.
4.
Once the egg is cool, use a cracking device, such as a teaspoon, to lightly tap the
shell in several places so there are several large cracks in the shell. Do not make too
many cracks. There should be several large pieces of eggshell.
5.
Place the egg on a layer of paper towels or newspapers.
6.
Try to move the pieces of the cracked egg shell around on the surface of the egg.
(Don't remove them; just see if they slide around.) There should be slight motion
allowed by the membrane holding the shell to the rest of the egg inside.
7.
Next, find two sections of the egg that are large and on opposite sides of a crack.
Use your index fingers and gently pull the two sections away from each other.
Observe what happens within and around the crack between the pieces. Record
your observations in Table 1.
8.
Stay in the same area of the egg and push the two pieces toward each other.
Observe what happens within and around the crack. Record your observations in
Table 1.
9.
Stay in the same area of the egg and try to slide one section of the shell up or away
from you and pull the other down or toward you. Observe what happens within and
around the crack. Record your observations in Table 1.

Questions and Conclusion
1.
If the egg is a model of Earth, what does each part of the egg represent? (Use the chart
below.)
Portion of Egg
Part of the Earth It Represents
Whole egg
earth
Egg shell
the crust
Cracked pieces of egg shell
plate tectonics
Egg white
earths mantle
Egg yolk
earths core
2.
How does your model demonstrate the differences between the types of tectonic plates
and the resulting observations in the asthenosphere? the model shows the different

types of boundaries moving them apart was divergent together was convergent and
pass was transform
3.
How did your hypotheses of your Tectonic Egg Model compare to your experimental
results? everything was correct
4.
What are some shortcomings of using this model as a replicable of the Earth? Suggest
a way that a scientist could create a more accurate model of Earth’s tectonic plates.well
the eggs could end up breaking they could try to find a better material to use instead of
eggs
