Science 90 - Dec 15

Today we finished our electricity unit by looking at the last 2 examples on electrical energy cost.  We then looked at how to calculate electrical efficiencies.  This also led into a quick lesson on the ENERGUIDE label and what information that tells us.  This was all covered on slides 78-83 in the powerpoint.  Students then had the rest of class to work on the worksheet for Activity C26 that deals with energy consumption in your home.  This is to be completed for tomorrow along with the vocabulary sheet that includes all the key terms that were introduced in this unit.
