Mrs. Marcia Gaston

Teaching science is my passion! I graduated from Oklahoma Christian University in 2006 with a B.S. in Science Education. I have taught Biology, Honors Biology, AP Biology, Physics, PreAP Physics, Chemistry, IPC, Earth Science, and Environmental Science. I have been blessed to teach at Little Elm High School since 2012. I enjoy seeing students learn the concepts of science and connect their learning to the world around us. I am excited to be your teacher this year. Biology can be a challenging course but I know we will be able to work and learn together. I look forward to an exciting year!
