Virginia BIOSTEM Resources
The Virginia Department of Education and the Virginia BIO Foundation are thrilled to announce the release of an exciting new resource for teachers. The Virginia bioSTEM Resources program offers middle and high school educators a range of bioscience and technology resources they can use with their students. The resources were selected by middle and high school teachers who engage their students in bioscience and technology concepts in an effort to prepare them for the exciting field of bioscience and biotechnology.
Each resource includes a title, description, and correlation to the 2010 Science Standards of Learning. The Virginia bioSTEM program is a partnership with the Virginia BIO Foundation. Send your feedback and recommendations for additional resources to Science@doe.virginia.gov.
Thanks to Melissa Csikari, Cathy Burke, Alice Scheele and Jimmy Green for their work in finding and describing the resources that make this page possible.
