The three bundles in this Grade 2 model are characterized by the overarching theme that a “variety of objects, organisms, and systems are made up of parts”—an idea that applies to the physical, life, and Earth and space sciences, as well as engineering. Each of the three bundles also uses an engineering-related question to drive instruction.
The Grade 2 Disciplinary Core Ideas (DCIs) in physical science focus on different kinds of matter and their observable properties and that some changes caused by heating and cooling can be reversed and some cannot. In Earth and space sciences, the DCI emphases are on wind and water, their roles in shaping the Earth’s surface, and how humans can limit their effects. Students also learn that some events on Earth occur very quickly, while others can occur very slowly. In the life sciences, the Grade 2 DCIs emphasize the needs of plants, how they depend on animals for seed dispersal and pollination, and the diversity of life found in different habitats.
