Gots and Needs
Gots (Aha!)
• I love the models… A definite addition to my
Earth science lesson.
• The entire evening was new for me.
• Love that you modeled NGSSWe discovered what
earthquakes were. Loved the 2 demos- great
models.
• Good ideas for my physics class when we study
friction and motion
• How much these types of models can help us
understand about plate motion (stress build up,
deformation, etc.)
Needs
• Earthquake Date to compare to our model.
• Myth Buster (explain why this is or isn’t true) Several small earthquakes on a particular fault
make it less likely that there will be a big
earthquake.
• Any hypothesis about why the Cascadia zone
has been quite for so long? Why are they
predicting such a bit one?

Why the Cascadia zone has been
quite for so long?
Heat/Water? - Smectite-Illite conversion
Why are they predicting such a bit
one?
• Past history
• Subduction zones allow more fault area in the
brittle zone.
