GRADES K-12 ENERGY EXPO UTILITIES

Utilities
Human Power Generator Level K-12

Materials:
• This experiment uses The Windstream® 12V DC Educational Light Box.
• The Light Box holds a 12V, 50 watt incandescent bulb and a 12V, 3 watt LED bulb.
• One or more small electric powered device such as a radio.
• Power View Data Logger.
• Computer to view power output
Activity:
1. Using the hand crank, take turns generating enough electricity to power the three types of light bulbs.
2. Next, use the hand crank to demonstrate how much physical power needs to be generated to listen to the radio.
3. Use the Power View Data Logger to monitor the output needed to power the light bulbs and radio on
your computer or laptop.
Observation:
List the various light bulbs in order of most energy needed to least. How does it compare to the radio? How much energy would you need to generate to listen to the radio for 10 minutes, one hour?
NGSS standards addressed with this activity include:
MS.Matter and Energy in Organisms and Ecosystems
MS-LS-1. Analyze and interpret data to provide evidence for the effects of resources availability on organisms and populations of organisms in an ecosystem.
The state of Kansas is fortunate to have an abundant supply of energy resources. The goal of the Kansas Energy Expo is to provide an opportunity for students of all ages to learn more about the state’s resources and how energy works to power their everyday lives.
Through hands-on experiences, interactive displays and engaging presentations, students will explore five areas:
• Oil and Gas
• Transportation
• Energy Efficiency
• Utilities
• Renewable Energy
