The Example Bundles (formerly known as the Model Content Frameworks for Science) demonstrate various ways that curriculum developers can bundle the Next Generation Science Standards (NGSS) within a school year. "Bundling" is an important strategy for implementing the standards because it helps students grasp connections between concepts and brings coherence to classroom instruction.
The NGSS Example Bundles helps explain the process of organizing the standards for coherent instruction and is intended for curriculum developers, including educators in the field and commercial publishers.
"Bundles" are groups of standards arranged together to create the endpoints for units of instruction. Bundling is just one step in a curriculum development process; many other steps are required to create instructional materials designed for the NGSS.
