During this unit students learn that matter can be described and classified by its observable properties. They test a variety of materials to determine which have properties that are best suited for an intended purpose. Students will ask questions, make observations, and gather information about a simple problem that can be solved through the development of an improved object. They then make a recommendation to Sanford Underground Research Facility (SURF) engineers about which materials they consider to be the best fit for the job and why.
As a Matter of Fact-- Properties of Matter
2-PS1-1 Plan and carry out an investigation to describe and classify different kinds of materials by their observable properties.
2-PS1-2 Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose.*
K-2-ETS1-1 Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.
