One very useful feature of Google Scholar is its ability to allow for easily finding articles which have cited an article that you have found. When looking at search results, check for the 'Cited by X' link underneath each result. That will tell you how many subsequent articles (that Google Scholar is aware of...it's not 100% comprehensive! This is a ballpark figure) have cited this particular article.
Try it using the example article from your assignment:
Cochran, K.H.; Barry, J.A.; Muddiman,D.C.; Hinks, D. Direct Analysis of Textile Fabrics and Dyes Using Infrared Matrix-Assisted Laser Desorption Electrospray Ionization Mass Spectrometry. Anal. Chem. 2013, 85, 831−836
