GSES+Barnes+2015-2016

**Ms. Barnes**
Your Task: Use your classroom combined data to answer the questions below to share in how to save the world.

1. What were the biggest vampires you found?

The largest vampire we found in our class was a desktop computer. For our class, it used an average of 18 watts of standby power. That said, we found far few vampires than we have in past years. As we looked at past data, we noticed how much it has improved!

2. How much money could your class save each month by unplugging vampires?

$64 for our class for the month ((about $3/student)

3. How much CO2 would be reduced if your class unplugged the vampires each month?

28,879.6 pounds of CO2! That's a lot!

4. What was the most surprising thing you found while studying this standby power unit?

We were the most surprised at how quickly a little energy loss becomes wasteful when you look at it across many households. (Also by how much standby power use has improved. Our data shows a much rosier outlook than much of the data posted online which is based on older numbers.)

Attach your classroom spreadsheet used for these calculations.
