Look at the photo below. This crack in the earth was caused by an earthquake. What do you see? What do you wonder? ]]> 2020-04-08 21:24:05 UTC https://padlet.com/rebeccarimoldi/ogmr48k0ljdg1zv9/wish/499540010 rebeccarimoldi https://padlet.com/rebeccarimoldi/ogmr48k0ljdg1zv9/wish/499540628 Essential Question:  How do earthquakes happen?

Build a tower out of paper. You can fold, twist, or tear the paper — whatever you need to make it stand tall. Place your tower on a plate and shake it back and forth, slowly at first, then stronger, and then slowly again. Does your tower fall? If it does, what could you do to help it stay up? Try again and see if it stays upright this time! ]]> 2020-04-08 21:26:44 UTC https://padlet.com/rebeccarimoldi/ogmr48k0ljdg1zv9/wish/499542788 rebeccarimoldi https://padlet.com/rebeccarimoldi/ogmr48k0ljdg1zv9/wish/499546194 What did this lesson make you curious about? What other questions do you have about earthquakes?
Talk to someone in your home and explain to them how earthquakes happen.  What can you do to prepare for an earthquake?  Explain your thinking.

Design, test and redesign until you have a stable structure!  Have fun and think like an engineer!
