Physical Science UNIT ( September -December)
Waves and Energy
P.EN.07.31 Identify examples of waves, including sound
waves, seismic waves and waves on water.
P.EN.07.32 Describe how waves are produced by
and Light vibrations in matter
P.EN.07.33 Demonstrate how waves transfer energy
when they interact with matter (for example: tuning fork in water, waves hitting a beach, earthquake knocking over buildings).
Solar Energy Effects
P.EN.M.60 Nuclear reactions take place in the sun
producing heat and light. Only a tiny fraction of the light energy from the sun reaches Earth, providing energy to heat the Earth.
P.EN.07.61 Identify that nuclear reactions take place in
the sun, producing heat and light.
P.EN.07.62 Explain how only a tiny fraction of light
energy from the sun is transformed to heat energy on Earth.
P.PM.07.11 Classify substances by their chemical
properties (flammability, pH, and reactivity).
P.PM.M.2 Elements are composed of a single kind of
atom that are grouped into families with similar properties on the periodic table. Compounds are composed of two or more different elements. Each element and compound has a unique set of physical and chemical properties such as boiling point, density, color, conductivity and reactivity.
P.PM.07.21 Identify the smallest component that makes
up an element.
P.PM.07.22 Describe how the elements within the
Periodic Table are organized by similar properties into families (highly reactive metals, less reactive metals, highly reactive nonmetals, and some almost completely non- reactive gases).
P.PM.07.23 Illustrate the structure of molecules using
models or drawings (water, carbon dioxide, table salt).
P.PM.07.24 Describe examples of physical and chemical
properties of elements and compounds (boiling point, density, color, conductivity, reactivity).
Changes in Matter
P.CM.07.21 Identify evidence of chemical change through
color, gas formation, solid formation, and temperature change.
P.CM.07.22 Compare and contrast the chemical properties
of a new substance with the original after a chemical change.
P.CM.07.23 Describe the physical properties and
chemical properties of the products and reactants in a chemical change.
