Day 91: Hair Dryer in the Bathtub


OK.  I got your attention. Today in IS I we started the chapter on atomic structure and bonding with an ENGAGE activity focusing on electrical conductivity. Four solutions were tested using a crude conductivity device (light bulb) for qualitative data and a conductivity probe for quantitative data. We all had to look up microsiemens/cm as the unit for electrical conductivity! The cards in front of the beakers are mixed up on purpose as we figured out what was in each beaker. We discussed the danger of electrical devices near water and how the body makes the solution salty.
