Standard 1: Understands basic concepts about structure and properties of matter
Interval Benchmark 1: Knows properties of objects and materials
Grade Level Benchmark	Vocabulary	Information	Skills	Classroom Resources
a: Knows objects have many observable properties such as size, weight, shape, color, temperature, composition, and the ability to react with other substances	observation property size weight shape color temperature composition reactivity	Knows examples of common observable properties	Observes properties of objects
b: Uses tools to measure properties of objects	measurement measurement tool measurement unit measurement scale	Knows that some properties of objects can be measured Knows appropriate measurement units for different attributes	Selects appropriate tool to masure a given property Reads scales on measurement tools
c: Classifies objects according to their properties	classification property	Knows properties of common objects Knows that objects may have some properties in common, but may differ in others Knows that objects may fit into more than one category Knows that classifying objects can assist in learning about an individual object or a group of objects	Groups objects according to a specified property Develops a simple classification system based on a limited set of properties
e: Understands matter can be changed from one state to another by heating or cooling	matter state of matter change of state heating cooling	Knows that substances can change from one state to another Knows the effects of heating on different substances Knows the effects of cooling on different substances
Standard 2: Understands energy types, sources, conversions, and their relationship to heat and temperature
Interval Benchmark 1: Knows light, heat, electricity, and magnetism
Grade Level Benchmark	Vocabulary	Information	Skills	Classroom Resources
a: Knows light travels in a straight line until it strikes an object	light direction straight line motion	Knows that light can move from one place to another Knows examples of how light changes direction when it strikes an object
