The Setup:

First of all, I setup a ‘stand’ for the iPad, so that it could project anything underneath it.  Being a science teacher, I have access to plenty of lab stands and clamps (I actually wrapped the two metal rods in electrical tape to protect the iPad2 from scratches).

I gently rested the iPad2 on the stand, being careful to center the camera on the lab table below, and secured it with a large rubber-band.

I found that I needed a wide stand so that students could fit their whiteboards underneath without difficulty.

This system is also flexible, as it is wireless.  I can carry it back to the lab and showcase individual student work to help direct a laboratory investigation.  Taking a picture, I was even able to annotate over a photo by importing it through an app like the Educreactions Interactive Whiteboard app.

The cost for using a coffee maker?  $10.  While this is a seemingly small fee for a convenience, maybe there is an alternative solution to help save money (and energy) and keep everyone happy.

Cuisinart Thermal Coffee Maker

Energy Efficiency: Not all coffee makers are created equally in their energy consumption.  Why not choose an energy efficient model?  A thermal coffee maker (like the Cuisinart DTC-975) uses less energy than a standard coffee maker, as the brewed coffee is stored in an insulated carafe.  Thus, there is no energy wasted heating a burner underneath a glass pot.

Economy of Scale:  Why not consolidate a few coffee makers into fewer, more centralized pots?  On my floor alone, there are at least 3-4 coffee makers that are used daily and often make only half pots each.  Having fewer pots that make a full pot at a time would reduce multiple uses of heating elements.  It makes sense to avoid single-cup brewing machines.

Opportunity to Learn: Combining both of these ideas could even turn into a class project, where students could use wattage meters (like the Kill a Watt meter) to monitor coffee makers to identify the most energy efficient models and brewing practices.
