The Baylor College of Medicine has done a great job of crafting excellent materials for students and teachers of biology over the past few years. This corner of its BioEd Online site focuses in on a range of lesson plans for classroom use. All of these lessons are aligned with national standards and are sorted by format, topic, and grade level. A good place to start is the STEM After School area. Here, visitors can find resources for younger students that will help them get excited about studying infectious diseases, the solar system, and microscopic organisms. The other three sections covered here include Resource Collections, Teacher Guides, and Lessons by Topic.
