About Margaret:

Margaret McEwen is a teacher at Parish Episcopal School in Dallas and has written for talkSTEM in 2015. You can read her previous post on our blog. Her B.S. in biology is from SUNY Brockport and her MLA degree is from TCU. She has taught middle school and high school science for over 20 years. A former medical technologist, her love of teaching and all things science was spawned by an incredible teacher she had in high school, Charles Collins. She seeks to make science an active part of her student’s lives by exposing them to science as it exists in their daily lives. Margaret firmly believes science is revealed by doing, and students in her classes have opportunities to personalize their learning. She was instrumental in bringing STEM into the middle school science curriculum at her current school. Follow her professional life on Twitter @MMMcEwen
