2-PS1-1: Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties
Science and Engineering Practice: plan and carry out an investigation -- Students will test a mystery substance (oobleck) and make observations to answer questions
Disciplinary Core Idea: structure and function -- matter can be described and classified by its observable properties. Students will come up with ways to test this mystery substance.
Cross-cutting Concept: cause and effect -- Students will test oobleck to see if it reacts like other liquids.
