Reflection: Classroom Setup Measuring Kilowatts - Section 1: Engage


Before class I prepared for the lesson. I have three Kill-A-Watt stations and I place four or five devices at each station. Students move from station to station in groups, measuring the watts of various  devices.

I have collected various electronic devices (mixers, cell phone, iPad, fans, computers, TV, DVD player, etc.) from home and from the teacher's lounge. Luckily I am near the lounge so I can get data from the refrigerator, microwave, etc. 

If you don't have access to the big appliances, use an on-line energy calculator. There are lots of energy calculators on-line. Check with your local energy provider to see if they have one.   I use Rapid Tables because of the information students get and because it is easy to create data tables and it is a quick lesson about how technology makes our lives easier.

Measuring Kilowatts

Unit 4: Measuring Energy
Lesson 2 of 4

Objective: SWBAT examine personal use of energy as measured in kilowatts by creating a spreadsheet to easily analyze data.

Big Idea: How much energy do we really use? Authentic technology integration is supported in the lesson as students create an Excel spreadsheet to analyze data. Students analyze the spreadsheet to determine a personal contribution to climate change.
