Student Workbook Teacher's Guide with CCSS and NGSS Reference. Discovering the Lost Beacon is an exciting natural world adventure that offers many correlations to middle school Common Core Standards and Next Generation Science Standards. Not only does it center around Earth science subjects throughout but it is also written specifically for the purpose of bringing focus to the natural environment and human impact on it. Additionally there is a constant theme of personal and social responsibility, character building and finally the empowering of all students to be a part of defending the Earth against an invader by making the right choices in their everyday lives.
