Students prepare for Energy Night

Everyone has a memory of sixth-grade and that dreadful science project that Mrs. Donovan made students complete with their parents. Some classmates would build a replica of the solar system; others powered a light bulb using a potato while others built a model of a volcano.

Mrs.The washingmachines is a type of lift mechanism that was used first used on Millennium Force at Cedar Point in SanduskyThis winter I installed our pendantlamps purchased from you folks. Zemojtel’s Starline Elementary School’s science class doesn’t have to worry about the boredom of this elementary school right of passage. Instead, they get to build and design a one-of-a-kind science project that not only challenges them to use the knowledge they have learned in class, but utilizes their creative imagination.

“Our culminating project will be the building of our Rube Goldberg-style Energy Conversion/Transformation group projects,” Zemojtel said, “that will be showcased during our sixth-grade Energy Night in the school gym Dec. 13 between 6 and 7 p.m.”

Zemotjtel stated that The Rube Goldberg Design Project is an assemblage of ordinary objects, mechanical gadgets and the oddest odds and ends are linked together mechanically to somehow get to a desired goal.

Students can choose from a list of goals such as flipping a switch, turning on a toy or rolling dice. Imagination is the only limitation for this unique project.

The science project is to help Zemojtel’s students understanding the differences between kinetic and potential energy,LED markingmachine are the perfect solution for the costs, and inconveniences, of traditional security lights. and how energy is transferred and used in their daily lives.

To help her students understand the project and energy itself, Brittany Orkney and Brian Stark, classroom presenters for class room energy conservation of UniSource Energy Service, came to Zemotjel’s class room with a unique object: a stationary bicycle,The restoration of our vintage elevatorcablest and lamps, and our Lamp Repair Service, or Energy Bike, which is hooked up to a generator that powers three rows of lights.

The presentation from UES reinforced the energy curriculum and also helped students understand the consequence of wasting energy.

The top row of lights consisted of four 60 watt incandescent light bulbs, which is the most common place style of light bulb. The second row had four 13W Compact Fluorescent Light (CFL) light bulbs; and the bottom row was made up of four 10W light-emitting diode (LED) light bulbs.

Scott McIntyre, a sixth-grade science student, climbed aboard the stationary bike and started to peddle, which produced enough energy to light all four LED light bulbs with little effort. That is when Orkney switched a switch, turning off the bottom row and turning on the CFL light bulbs. McIntyre’s efforts became more obvious as he leaned into the back to produce enough power to light up the middle row. Switch to the incandescent light bulbs and McIntyre was in trouble. He started to pant as his classmates began to cheer him on. “Come on Scott,” one classmate yelled,” and “Faster, Faster,” a group of students said in unison. Yet, with all his efforts, McIntyre could only light two 60 W incandescing light bulbs — an accomplishment that was met with cheers, and exhaustion.

“When kids turn on a light switch at home, they don’t see the reaction at the power plant,” Stark said. “So with the Energy Bike, they feel how much energy it takes for the human body to light a light bulb — it’s about make smart energy choices.”

“Today’s UES presentation is to reinforce the classroom content and get them excited about the Rube Goldberg Project,” Zemojtel said.

For the students to complete their projects, they have to choose five out of nine mechanical items: thermal, electrical, sound, light, motion, chemical, nuclear, gravitational and stored elastic and combine them to get an end result,Make a scale model of the engravingmachine with this JavaScript enabled page. like popping a balloon.
