All of us can make a difference. A local science teacher takes it a step further. At Harris Middle School, David Bolster tells his 7th grade students they not only have an opportunity, but an obligation to make the world a better place. He teaches them that concept by example.
David Bolster didn't plan on becoming a teacher. He graduated from college and went to work as a wildlife biologist.
"Here I was trying to figure out ways to save the world's wildlife," Bolster said. "When I realized I couldn't do that without an educated population.
The reason I became a teacher is I couldn't think of anything that was more important."
"I'm glad that I come and whenever the bell rings I'm sad when I have to leave." said 7th grader Rachel Gore. "I just have a gas every day getting out of bed and trying to figure out how to get kids excited and how to help kids figure out the world and their part in it, " said Bolster. "I had a teacher who taught me and I want to teach my students this same lesson: You have to contribute. You have to give back, you have a job to do, as a citizen on this planet and steward of this planet and as teachers we need to help students understand that role," he said. The students are getting the message. "We do paper pick up and it's recycling for the whole school. He tells us we need to to help save the world somehow," said 7th grader Cooper Haines. Bolster has set up a green patrol where students patrol cars during drop off and pick up and tells parents not to leave their cars idling for more than a minute. "We tell parents politely to please turn off your car. It wills ave gas, money and the environment," said Bolster. "Whenever we have a canned food drive or toy collection, I encourage each student to give a little to help others. We have great participation and they can see what a difference collectively they can make," said Bolster. "We each have an obligation to make this world a better place. Hopefully they get a little of that every day when they come in here, " said Bolster. 
H makes learning a fun and challenging experience. Now in his 20th year of teaching, students love his class.
