This poscast discusses cell echange with the environment.

Welcome to Ms. Polanco's 7th grade science bolg. I will use this bolg to help you keep up with the concepts being discussed in class. In order to do this, I am developing a series of podcast that will be featured on this page. Please download these podcast and use as a review for test, quizes and to complete homework. I hope you enjoy these podcast. Many of these podcast will be completed by your classmates and you as well. This is a great way to show your parents the kind of work you do at school. Hopefully, we will post the podcast about every two weeks. Listen to one and see what you think.
