Description
A 50-question summative unit test covering atomic structure, classification of matter (elements, compounds, mixtures), periodic table organization, physical and chemical properties, physical and chemical changes, evidence of chemical reactions, endothermic and exothermic reactions, the Law of Conservation of Mass, balanced equations, open and closed systems, and photosynthesis as a real-world chemical reaction. Aligned to NC Standard Course of Study PS.8.1.
Learning Objectives
-
Model atomic structure including protons, neutrons, and electrons with correct locations, charges, and relative sizes.
-
Classify matter as elements, compounds, or mixtures based on particle arrangement models.
-
Analyze periodic table patterns (groups, periods, metals, nonmetals, metalloids) to predict element properties and reactivity.
-
Distinguish physical properties from chemical properties and identify examples of each.
-
Classify changes in matter as physical or chemical and identify evidence of chemical reactions.
-
Classify chemical reactions as endothermic or exothermic based on energy changes.
-
Explain the Law of Conservation of Mass and use balanced equations to show atoms are rearranged, not created or destroyed.
-
Compare open and closed systems and explain why mass may appear to change in an open system.
-
Apply knowledge of chemical reactions, reactants, products, and conservation of mass to the real-world process of photosynthesis.
