It is clear there is little to no understanding of events; most of the information is clearly copied from the Internet or books. There has been a small effort made to paraphrase information from the research, but it is unclear whether or not the material was understood. At least 6 scientists, events, and models are clearly defined. Demonstrates some understandings of atomic contributions. There has been an effort to paraphrase and present material in a unique way. The material has been presented in a unique way that shows that the student have a clear understanding of the material. At least 8 scientist, events, and 3 models are clearly defined. Understanding of atomic contributions is adequate. All scientists, events, and models are clearly defined. There is a clear understanding of atomic contributions. 0 pts 1 pt

Sloppy, smudge marks, glue oozing out, crooked lines, poor handwriting etc…not much effort made to keep things neat. It is not very pleasing to look at. This is a very basic timeline set up. A few sloppy places could have been neater with just a bit more care. Neat with maybe one or two little sloppy places. Very neat. Clear effort made to avoid sloppy places. Scientists, models, and events are not linked. There is no evidence of comprehension or understanding. Appearance Neatness: Creativity and Aesthetics: References Documentation Understanding Comprehension of Events: It is not very colorful, neat or organized but it’s OK to look at. This is a nice timeline with some creativity in printing, event placement, or color Pretty nice to look at, maybe one or two unattractive places. This is a pretty creative timeline. It isn’t like all of the others with neat creative elements. Very nice to look at. This is a very creative and unusual. I really haven’t seen too many timelines like this, and the creativity goes beyond just a cool color or picture. 0pts 1pt
