STEM Chemistry

Post by rlmccarthy » Sat Jul 21, 2007 5:32 pm

My county is implementing a Science, Technology, Engineering, and Math (STEM) Program this coming year and I am co-teaching STEM chemistry and algebra 2. I wanted to incorporate energy conservation and transfer into our curriculum via engineering/technology projects. My hope is to inspire the future renewable/inexhaustable energy scientist for our future generations. If anyone has ideas for this "engineering challenges" please email me, rlmccarthy [[at]] smcps.org.
Thank You!!!

Engineering challenges for STEM chemistry

One big chemical engineering challenge for sustainable energy is to make better-performing batteries. Could you have students learn about the manufacturing process, try to make some batteries in the classroom, and discuss how they might turn them into salable items?

STEM Chemistry energy transfer engineering

You might be able to generate hydrogen from wind using a tabletop turbine and a small fuel cell. At the Massachusetts Science Fair, I reviewed a project where students used a LEGO motor as a generator to power LEDs in series, thus proving the dynamo could provide enough voltage to make it through the diodes. If so, then it could also run a fuel cell backwards to make hydrogen, and you can power the motor with a table top wind turbine.

You would be covering energy transformations, and you could use some simple algebra to combine losses at each step, perhaps.
