In this lesson, students design a solution for saving money on their utility bills by suggesting changes to appliances and energy use in their homes. They use data from previous lessons including Energy Audit one, Energy Audit: Personal Energy Use (Part 2), and Light's Out. In these three lessons students collected data on their individual energy use, the electricity, natural gas, and oil use of their household. And compared the electrical out put and use of different types of lightbulbs.
If you are considering using this lesson and have not used those three lessons, it does work as a stand alone. However, you may want to adjust some of the language I have provided that refers to previous lessons and data sets.
I tell my students that their task is to identify at least three items in their home that they can make more efficient in order to change their utility bills.
I offer a few rules and some hints to working through this problem.
In addition, students must answer some questions about the items that they have selected. The questions are as follows:
Finally, students create a technical presentation of their findings. The expectations for the presentation are as follows:
Give time for students to share their plans and discus with the class.
Below is a student presentation for you to use as example.
In the video below I explain a bit home this lesson embodies NGSS Science Practice 8
Use the attached rubric to evaluate student presentations. I give them this rubric at the beginning of the project and asked that they come the day self-evaluation, scoring themselves in the categories, and turn this in on the date they present. I then use their form and add my scores and comments.
