This was one of my personal favourite projects well more like 3 projects. 

The qualitative vs quatitave observations, the gummy bear diffusion and the scratch game

My favourite one was the gummy bear diffusion I did it primarily by myself but had a bit of help from others and my presentation was one of my best projects I have made I will link it below, but I am very productive of it because one of my goals for this year was to have more eyecatching presentations and I feel I have accomplished that.
