Discover on the graph, the blue part represents clams which can be lifeless. Yellow bars are clams that had been alive. The X axis signifies the month. (The scholar 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 complete clams had been recovered in April. The subsequent asks what number of of these clams had been alive and what number of had been lifeless. The alive clams are straightforward, simply observe the yellow bar (about 21). Useless clams require some math. Researchers recovered 48 complete 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 information evaluation. As college students progress by science, they may encounter many kinds of graphs.

Information evaluation is a part of the NGSS Science and Engineer Practices.
