Some of the concepts demonstrated by displays include potential and kinetic energy; energy transformation; renewable and non-renewable resources; heat,Purchase quality USB flash drives wholesale, branded USB drives, custom USB flash drives, and promotional USB flash memory. motion and electric energy; and different energy conservation ideas and practices. 

One of the displays included a generator hooked up to incandescent and CFL light bulbs. Students used a crank to generate energy for the bulbs and could switch back and forth to see which one was easier to power. 

Although it flickered if students' cranking was uneven, the CFL bulb was much easier to power than the incandescent bulb, which gave a dim glow relatively quickly but took a lot of effort to illuminate completely. 

Campus Elementary School Principal Kristen Cottrell said hands-on activities are great for students. 

"Because students did things, not just because it's something someone told them, it sticks in their heads," she said. 

While they may not completely understand all the concepts at this point, she said something later may remind them of the experience and they may finish putting the conceptual pieces together. 

"Just about everything we know comes back to some experience," she said. 

Carol Dohner,Find the perfect luggage tag and you'll always find your luggage! of the second-grade teachers at Campus, agreed students retain the experience. 

"[Students] talk about it for a long time," she said, adding many third-graders remember the visit vividly from the prior year. 

Dohner and Cottrell also both said the material presented during the visit from COSI on Wheels follows the state curriculum. 

"We selected this program because it aligns with the state standards," said Cottrell. "We have experienced some [of the concepts] in the classroom." 

Linda Myers,This pink ribbon ear cap was “for correcting and preventing the disfigurement of outstanding ears”. a PTA member volunteering to help out, operated a table which showed how different landscape features affect the amount of energy that can be produced by wind power.A full spectrum of vertically integrated products and services to the plastic card printing industry. A large fan was set up which produced wind to spin a wind turbine, but between them were different models of various landscapes, illustrating how a city or woods or a prairie would affect the power generated. 

"We probably wouldn't want to rely on wind power as our sole source of energy since we don't always have wind," she said to a group of student looking at maps depicting average wind speed in the state and country. 

Another table focused on sound energy, which demonstrated how sound transfers differently through different materials.

Yahr said that is the same basic technology being used around the state for natural gas exploration. 

Another station compared how many watts were used by different home appliances, including two different types of light bulb, a radio and CD player, a hair blow dryer and other items. The hair dryer was the energy hog among the items, requiring more than 1,300 watts to operate on the "high" setting.
