School Subject(s): Math, Science, Statistics
The purpose of this curriculum unit is to increase a high school student’s awareness of electricity; how it is measured and the amount that is used. The unit strives to apply quantitative tools to a scientific context by investigating and analyzing various aspects of electricity sources and usages.
After learning to measure electricity using an energy monitor and various types of light bulbs, the students will read an article about a village in India that has no electricity and discuss the ramifications. Students or student teams will use a choice board for project topics and presentation methods to research electricity themed issues and present their findings to the class. The research presentation must include data analysis and data displays.
The hope for the unit is that students will internalize their findings and those of their classmates and make real world connections for their future.

The more details students learn about electricity, its sources, its production, its availability and the impact on the environment, the more involved they are likely to become in some aspect of it. In the TIP seminar “Penn Laboratory on Energy, Sustainability and Environment” we used a Fermi questions to explore multiple topics in energy, sustainability and the environment. There were assignments that allowed the fellows to explore the intricacies of a problem and personalize it, realizing that there is more than one solution and more than one way to approach an outcome. One of the ways this curriculum unit hopes to arouse interest is by giving students a choice for their research. The only requirements are that they display and analyze the data they collected or researched. It is the hope that through the preparation of their presentation or from the presentations of their peers that topic of electricity becomes real to them.
The Next Generation Science Standards makes the following statement about making connections to the Common Core State Standards for Mathematics. “During the middle school and high school years, students develop a number of powerful quantitative tools, from rates and proportional relationships, to basic algebra and functions, to basic statistics and probability. Such tools are applicable far beyond the mathematics classroom. Such tools can also be better understood, and more securely mastered, by applying them in a variety of contexts. Fortunately, the NRC Framework makes clear in its Science and Engineering Practices (Analyzing and Interpreting Data, Using Mathematics and Computational Thinking) that statistics and mathematics have a prominent role in science. NGSS aims to give middle school and high school science educators a clear road map for how they can prepare their students for the quantitative demands of college and careers, where students need to apply quantitative tools in an applied or scientific context. For all these reasons, NGSS requires key tools from Grades 6−8 and High School Common Core to be integrated into middle school and high school science instructional materials and assessments.”
This curriculum unit could be done solely in a physics or statistics class, without the collaboration. It may be more difficult for the statistics teacher, but it is possible to de-emphasize some of science of electricity depending on the research topic they choose. A minimum review of “how electricity is measured” will be necessary.
This unit is designed for a high school statistics class. In my school, the seniors take statistics as a 5^{th} year math elective. All seniors must also take physics, so this unit is designed for collaboration between the math teacher and the physics teacher. The unit could be adapted for use in any math or science class where real life issues are explored or emphasized.
The overall objectives of the lesson is to apply statistics to data collected or researched in order to display, analyze and make inferences for the future. The specific objectives for the unit will include:
The suggested strategies for this unit are meant to give the students freedom and independence. Academic choice helps engage and motivate students. It allows for creativity and exploration into areas of interest. The more students have choice in assignments, the more responsibility and ownership they have.
The research topics suggested all contain the directions to investigate and analyze. This also allows freedom. The teacher or student will have to answer the question “how deep?” One of the most rewarding things for me when investigating is to extend the thread further and further and wind up with at least 10 tabs open on my driver. In the olden days I would do the same with encyclopedias! The analysis will depend on the level of the students’ knowledge in statistics. A simple analysis such as the mean kilowatt hours of electricity used for 12 months could be sufficient, or perhaps a more complex analysis such as the standard deviation of electricity usage from school to school.

This unit is intended for an interdisciplinary physics and statistics class, which assumes the students know something about electricity. If this is not the case and some more lessons in electricity are desired, I have provided the following outline of how it could be done.

N-Q.1. Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and origin in graphs and data displays.
N-Q.2. Define appropriate quantities for the purpose of descriptive modeling.
N-Q.3. Choose a level of accuracy appropriate to limitations on measurement when reporting quantities.
Science examples: (1) Recognize the difference between intensive and extensive quantities (e.g., a quantity with units of tons/acre is insensitive to the overall size of the area in question, unlike a quantity with units of tons). (2) Carefully format data displays and graphs, attending to origin, scale, units, and other essential items.
