2-PS1-1 Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties. 

Sort objects by observable properties, such as size, shape, color, temperature (hot or cold), weight (heavy or light), texture, and whether objects sink or float.

 Sort objects based upon two attributes, and explain the system they have used to develop their own design for a building 

Sort objects by materials type (what the objects are made of/from). Children learn that the same material can take many shapes and that objects with the same function can be made of different materials
