We began class by watching a Bill Nye video about the moon. Next, we talked about out calendar and determined that our calendar is a solar calendar because it is based on Earth's revolution around the sun and not a lunar calendar. We began examining 3 alternative calendars and discussing the strengths and weaknesses of each.
We used a seismograph model to exam how scientists can measure the strength of earthquakes. We also discussed that earthquakes typically occur near plate boundaries. Students made their own seismograms and examined the differences between them.
We used paperclips to model the slime reaction yesterday. Single paperclips represented a monomer, linked paperclips were the polymer, and colored paperclips added to the chain represented cross-linking with sodium borate. Students compared properties of the 3 models.
