In Power Tech 10 Mr.Kent thought us how engines work and how to fix bikes. He carefully went through demos with video examples and him walking our class throught it. If something was not explained properly he would show us physically and help us understand. Recently since the weather has been nice and Ive had to bring out the lawnmower to cut the grass in my backyard. Something was up with the engine and my dad thought we would have to take it in and get it fixed but, instead I took the front hub off and fixed it. I used my critical thinking skils here.
