Standard 1:  Understands basic concepts about structure and properties of matter

Interval Benchmark 1: Knows properties and changes in matter

a:

Knows physical properties, such as density, boiling point, and solubility, are independent of the amount of sample

b:

Knows physical properties of substances can be used to separate a mixture

c:

Knows some substances can react chemically to form new compounds with new properties

d:

Understands the conservation of matter in physical changes and chemical reactions

Interval Benchmark 2: Knows the structure of atoms and properties of matter

a:

Understands matter is made up of tiny particles called atoms and that different arrangements of atoms make up all substances

b:

Understands atoms often combine to form a molecule, which is the smallest particle of a substance that retains its properties

c:

Knows the type of movement of the atoms in matter that determines its state

	Standard 2:  Understands energy types, sources, conversions, and their relationship to heat and temperature

Interval Benchmark 1: Knows transfer of energy

a:

Understands energy cannot be created or destroyed but only changed from one form to another

b:

Knows energy comes in different forms, such as light, heat, chemical, nuclear, mechanical, and electrical

c:

Knows light interacts with matter by transmission, absorption, or scattering

d:

Understands heat can be transferred through conduction, convection, and radiation and flows from warmer objects to cooler ones

e:

Understands heat is often a byproduct of energy transformations

f:

Understands electrical current can be used to do work

	Standard 3:  Understands motion and the principles that explain it

Interval Benchmark 1: Knows motion and force

a:

Understands vibrations move at different speeds in different materials, have different wavelengths, and set up wave-like disturbances that spread away from the source

b:

Knows an object's motion can be described by tracing and measuring its position over time

c:

Understands effects of balanced and unbalanced forces on an object's motion

d:

Understands general concepts related to gravitational force
