TeacherJamie Newcomb
Subject AreaComprehensnive Science III
Grade Level8
Week #17
Unit of InstructionProperties of Matter - Chemical Changes
Standard(s) Taught

SC.8.P.9.2   Differentiate between physical changes and chemical changes.

SC.8.N.1.6  Understand that scientific investigations involve the collection of relevant empirical evidence, the use of logical reasoning, and the application of imagination in devising hypotheses, predictions, explanations and models to make sense of the collected evidence

SC. 8.P.9.3  Investigate and describe how temperature influences chemical changes.

SC.8.P.9.1   Explore the Law of Conservation of Mass by demonstrating and concluding that mass is conserved when substances undergo physical and chemical changes.
 
SC.7.N.3.1  Recognize and explain the difference between theories and laws and give several examples of scientific theories and the evidence that supports them.
 

 

Learning Targets and Learning Criteria

Students will:

• differentiate physical and chemical changes in matter
 
• cite examples of physical and chemical changes in matter
 
• investigate physical and chemical changes in matter 

      o NOS Focus – Inferences and Observations

• explain how temperature influences chemical changes
 
     o NOS Focus – Independent and Dependent Variables and Control Groups

• explain why mass is conserved when substances undergo physical and chemical changes according to the Law of Conservation of Mass

      o differentiate between a law and a theory o NOS Focus- Theory vs. Law
 
• investigate the law of conservation of mass using models, such as: o chemical equations, experiments, and demonstrations
 
• design an investigation to explore the Law of Conservation of Mass
