Genius Hour Reflections

I select Mechanics for my genius hour because I like to work on cars and trucks. I hope to gain more experience in mechanics. My experience so far is good I learned how a trucks engine works and its parts work. I have improved my skills in Mechanics, I know a little bit of a trucks engine. Now after I researched parts of a trucks engine, I learned a lot more of a trucks engine. My greatest challenge is to build a model of a trucks engine.  I have researched the internet for  2 hours to learn the parts of a trucks engine and how it works.
