Objects have many observable properties, including size, mass, shape, color, and temperature.
Properties of matter can be measured using tools, such as rulers, balances, and thermometers. Measure length, mass and temperature of various materials in nonstandard and standard units. Sort objects and materials based on a single attribute. Objects can be described by the properties of the materials from which they are made, and those properties can be used to separate or sort a group of objects or materials. Investigate that some materials mix with water and others will not.
