In Educator's Life Science series, Nehlia covers important concepts with diagrams and relates abstract ideas to real world examples. Extra examples at the end of each video help viewers practice their new found knowledge. Topics covered include Photosynthesis, Animal Classification, Cell Structures, Genetics, and Ecology. Nehlia McIntyre received her Master's of Education and has been teaching a variety of middle school and high school science courses for over ten years.
