[SC2015] (2) 1 :
1 ) Conduct an investigation to describe and classify various substances
according to physical properties (e.g., milk being a liquid, not clear in color,
assuming shape of its container, mixing with water; mineral oil being a liquid,
clear in color, taking shape of its container, floating in water; a brick being
a solid, not clear in color, rough in texture, not taking the shape of its
container, sinking in water).

3 ) Examine matter through observations and measurements to identify materials
(e.g., powders, metals, minerals, liquids) based on their properties (e.g.,
color, hardness, reflectivity, electrical conductivity, thermal conductivity,
response to magnetic forces, solubility, density).

2 ) Plan and carry out investigations to generate evidence supporting the claim
that one pure substance can be distinguished from another based on
