Concept B: Properties of mixtures depend upon
the concentrations, properties, and interactions of
particles
Predict the effect of the properties of the solvent or
solute (e.g., polarity, temperature, surface
area/particle size, concentration, agitation) on the
solubility of a substance
C11
Students will make Alum
crystals from its powder form
and water. Students will design
a procedure to maximize the
solubility for the crystal
making process.
Students will justify the
procedures they created.
Strand 1: Properties and Principles of Matter and Energy
2. Energy has a source, can be transferred, and can be transformed into various forms but is conserved
between and within systems.
Major Objectives IS Suggested Activities Suggested Assessments
Concept D: Chemical reactions involve changes
in the bonding of atoms with the release or
absorption of energy
Describe evidence of energy transfer and
transformations that occur during exothermic and
endothermic chemical reactions
Students will observe a
demonstration of endothermic
and exothermic reactions:
1) Reaction of barium
hydroxide and ammonium
nitrate.
2) Reaction of hydrochloric
acid and water.
Students will write general
equations that include the net
energy transformation as it
relates to the reactants and
products of the reaction.
