The lab introduction is about an experiment I had done in class. We tried out different experiments that use if and then methods. It is basically comparing to see if something is better than the other or if you make something bigger than the other.
The technical presentation is slides that my group and I made that explained our instruments. My instrument was the flute and I basically explained what I made it out of, what is appealing about it, and how do you play it.
The isometric sketch was done in class. We used our engineering note books to draw them while we watched a video. It shows you a 3 dimensional sketch in two dimension in technical and engineering drawings.
