Strand 1: Properties and Principles of Matter and Energy
1. Changes in the properties and states of matter provide evidence of the atomic theory
Major Objectives IS Suggested Activities Suggested Assessments
Concept C: Properties of matter can be
explained in terms of moving particles too
small to be seen without tremendous
magnification
Scope and Sequence – Properties of and
Changes in Matter
Grade 8
a. Recognize evidence (e.g., diffusion of
food coloring in water, light reflecting
off of dust particles in the air,
condensation of water vapor by
increased pressure or decreased
temperature) that supports the theory that
matter is composed of small particles
(atoms, molecules) that are in constant,
random motion.
Concept D: Physical changes in the state of
matter that result from thermal changes
can be explained by the Kinetic Theory of
Matter
Scope and Sequence – Earth’s Resources
R
a. Students will demonstrate random, constant
motion (Brownian motion) of small particles
called atoms and molecules by dropping
food coloring into water and observing
diffusion and looking at light reflecting off
dust particles. (1.1, 1.2, 1.3, 1.8, 2.1, 2.3,
4.1)
Grades 7 & 8
a. Given an example like water molecules,
students will draw and describe particle
motion. They will explain why the blue
food coloring moves randomly and
constantly.
a. Describe the relationship between the
change in the volume of water and
changes in temperature as it relates to the
properties of water (i.e., water expands
and becomes less dense when frozen).
Concept E: The atomic model describes
the electrically neutral atom
Concept F: The periodic table organizes
the elements according to their atomic
structure and chemical reactivity
R
T
a. Teacher will demonstrate water phase
changes and temperatures for boiling,
freezing, and melting. They will observe ice
floating in liquid water and create the crystal
pattern at 4 degrees Celsius.(1.1, 1.2, 1.3,
1.8, 2.1, 2.3, 4.1, 4.3, 4.6)
Grade 8
Not assessed at this grade level
a. Students will draw and describe the
molecules of water during phase changes
and label phase change temperatures.
Students will explain why ice floats in
liquid water.
