Grade 5
Students make claims about what factors matter for decomposition. They use evidence from an investigation to support their claims, and they begin thinking about explanatory mechanisms for why a particular factor matters, making connections to the life cycle of mold.

Grade 2
Students engage in multisensory exploration to generate claims about whether chocolate chips are solid or liquid after heat is applied. They support their claims with evidence from their investigation and grapple with the usefulness of the terms “liquid” and “solid.”
