How Can We Provide Energy to People’s Homes?
How Can We Provide Energy to People’s Homes?
How Can We Provide Energy to People’s Homes? is part of Smithsonian Science for the Classroom, a new curriculum series by the Smithsonian Science Education Center. It is aligned to a group of grade 4 standards. It has a focus on engineering with a secondary focus on physical science. In this module, students:
- Observe evidence of energy in systems and explore how that energy moves and changes
- Research how people obtain sources of energy for practical purposes
- Explain that some sources of energy affect the environment more than others
- Investigate how their designs affect the success of a student-built device
- Use their understanding of science and engineering to design and test a model house doorbell system that runs on solar energy
Below are digital resources that support teaching of this module.

State Profiles and Energy Estimates
This website identifies what energy sources are used for electricity generation in states you want your students to investigate. Select your state. When the Profile Overview page opens, scroll down to the [State] Energy Consumption Estimates bar graphs. Select the Electricity tab to display the [State] Net Electricity Generation by Source data. You can mouse over the bars to get the numeric value for the source graphed. The graph and data can be downloaded using the button on the site.
If your state displays data from “Other Renewables,” select State Renewable Electricity Statistics under the Summary Reports below the graph. Use the Generation section of the page to determine which renewables are used for electricity generation. Be prepared to identify these other renewables for your students.
This site is also used for student research in the Enrichment activity. To explore the locations of electricity generation plants in a state, select a state from the map on the opening page. Open the Layers/Legend pull-down menu and select “X Remove All” to clear the map. Students can select “All Power Plants” or explore plant locations by type through the same pull-down menu.
Electricity Transmission Diagram
This file illustrates the path of energy transmission from power plants to homes.
US Electric Grid
This website shows students the interconnectedness of our nation’s electricity generation and transmission system. Open the Layers/Legend pull-down menu and select “X Remove All” to clear the map. Then, under Pipelines and Transmission, select “Electric Transmission Line.” Close the Layers/Legends menu if it does not close automatically. The resulting map displays what is referred to as the “national grid.” Use a mouse and the controls in the upper left corner to zoom in on an area of interest.
