Discover on the graph, the blue part represents clams which are useless. Yellow bars are clams that had been alive. The X axis signifies the month. (The coed model is black and grey for printing.)
College students might want to perform a little math to reply the questions. For instance, one query asks what number of whole clams had been recovered in April. The subsequent asks what number of of these clams had been alive and what number of had been useless. The alive clams are straightforward, simply observe the yellow bar (about 21). Lifeless clams require some math. Researchers recovered 48 whole clams in April. 48 – 21 = 27.
This can be a good train for a unit on ecosystems and invasive species. It may be used for scientific technique and knowledge evaluation. As college students progress by means of science, they are going to encounter many kinds of graphs.
Information evaluation is a part of the NGSS Science and Engineer Practices.
