Week #6-9 (September 17-October 12)
Unit of InstructionCompounds & Mixtures
Standard(s) Taught

Standards:

SC.8.P.8.5 Recognize that there are a finite number of elements and that their atoms combine in a multitude of ways to produce compounds that make up all of the living and nonliving things that we encounter.

 

SC.8.P.8.9 Distinguish among mixtures (including solutions) and pure substances.

 

SC.8.N.1.1 Define a problem from the eighth grade curriculum using appropriate reference materials to support scientific understanding, plan and carry out scientific investigations of various types, such as systematic observations or experiments, identify variables, collect and organize data, interpret data in charts, tables, and graphics, analyze information, make predictions, and defend conclusions.

 

SC.8.P.8.8 Identify basic examples of and compare and classify the properties of compounds, including acids, bases, and salts.

SC.8.N.1.2 Design and conduct a study using repeated trials and replication.

 

Advanced

SC.912.P.8.7 Interpret formula representations of molecules and compounds in terms of composition and structure.

Advanced: SC.912.P.8.11 Relate acidity and basicity to hydronium and hydroxyl ion concentration and pH

Learning Targets and Learning Criteria

Students will:

• differentiate between atoms, elements, and compounds

• explain how elements combine to form compounds that make up all living and non-living things, for example: o atoms share/transfer electrons to create a bond between them (students do not need to know covalent and ionic bonding)

• differentiate between pure substances, mixtures, and solutions, including: o solutions are mixtures that may include multiple states of matter

• investigate different ways of making and separating mixtures and solutions, including: o using a funnel and filter paper, a magnet, dissolving substances, screens, evaporation, etc. 

• cite common examples and characteristics of acids, bases, and salts

• Investigate to classify various substances using the pH scale as an acid, base, or neutral

Advanced:

1. Use experimental data to illustrate and explain the pH scale to characterize acid and base solutions

2. Compare and contrast the strengths of various common acids and bases
