A Changing Earth

Fourth grade students are currently working through their science unit called "What Is Our Evidence That We Live On A Changing Earth?"  They have been learning about the hazards of earthquakes and volcanoes and how they affect humans and the landscape.  We have also done some reading about how engineers have come up with ways to make buildings more earthquake-resistant.  In our most recent lesson, students worked cooperatively to design and build an earthquake-resistant structure according to certain criteria and constraints and then test their buildings with a small and large earthquake simulation.
