Next Generation Science Standards are on their way, and will be to science what Common Core is to Language Arts and Math. A representative from our district was chosen to participate in the process and so when she is able, she passes along great resources to our science cadre.
The book Ready, Set, Science:Putting Research to work in K-8 Classrooms is one of those resources and is available FREE on pdf through the National Academy Press. It is a fabulous book and something I think that any teacher K-6 should read. As a bonus, there are sample lessons mixed throughout the chapters that support the big picture idea being discussed.
