4th Grade Science - Physical Science
Properties of Matter
-
Identify objects using observable properties (i.e., mass, length, and
volume), and measure those properties with the proper equipment
-
Identify properties of density and boiling and freezing points
-
Recognize materials exist in different states (i.e., solid, liquid, and gas)
-
Introduce the atom as the basic unit of matter
-
Distinguish that heat changes state through evaporation and condensation
Light, Heat, Electricity
-
Identify the basic properties of light such as reflection, refraction,
and absorption
-
Observe ways heat can be transferred through conduction, radiation and convection
-
Identify ways energy influences our lives
-
Explore ways energy is never lost, but how it changes form
Motion, Forces, Magnetism
-
Identify simple machines and their uses
-
Recognize the position of an object
-
Observe friction and its effects
-
Be introduced to gravity as a force
-
Distinguish the differences between mass and weight
-
Practice applying the criteria of the greater the object, the greater the
force needed to move the object
