March 30-31 Volcanoes!

Today in class we started a short unit on volcanoes. We watched two short clips on youtube--they can be found at

We then watched a demonstration of a volcano erupting and then another of a geyser erupting. Following the demonstrations we worked on the lab "Some go pop, some do not". This lab can be found on page 163 of our textbook. It will be turned in at our next class.
