Oelwein Schools industrial tech teacher Todd Kastli teaches about mechanics in such classes as "Basic Maintenance" and "Power, Energy and Transportation." 

Students learn to check and change oil and filters, change tires and prep batteries for winter.

Depending on the class, they may move beyond basic maintenance and also get to disassemble, reassemble, diagnose and repair small engines, wire some basic residential circuits and explore electronics.

Here are some photos of the students at work.
