TITLE : Unit 09: Solutions SUGGESTED DURATION : 15 days

Unit Overview

During this Unit

This unit focuses on the properties and classifications of solutions. Students are given access to the general solubility rules to apply during investigations. Students calculate molarity and dilutions using provided formulas. Students describe how the polar nature of water causes it to be a common solute for many solutions. Students differentiate factors that affect solubility and rate of dissolution of solids and gases through investigation. Students identify the types of solutions using formulas, solubility rules, and observations during investigations.

Safety Note

Chemistry is the high school science course where students are most likely to use chemicals and equipment that could harm the health of themselves and others. It is imperative that students and teachers plan and conduct laboratory investigations with a high level of focus and professionalism that ensures the safety of everyone.

 

 According to Research

“By the end of 12th grade, students should know that:

  • …an enormous variety of biological, chemical, and physical phenomena can be explained by changes in the arrangement and motion of atoms and molecules.

American Association for the Advancement of Science. (1993, 2009). Benchmarks on-line. Retrieved from http://www.project2061.org/publications/bsl/online/bolintro.htm.

    • Descriptive investigations involve collecting qualitative and/or quantitative data to draw conclusions about a natural or man-made system (e.g., rock formation, animal behavior, cloud, bicycle, electrical circuit). A descriptive investigation includes a question, but no hypothesis. Observations are recorded, but no comparisons are made and no variables are manipulated.
    • Comparative investigations involve collecting data on different organisms/objects/features/events, or collecting data under different conditions (e.g., time of year, air temperature, location) to make a comparison. The hypothesis identifies one independent (manipulated) variable and one dependent (responding) variable. A fair test* can be designed to measure variables so that the relationship between them is determined.
    • Experimental investigations involve designing a fair test* similar to a comparative investigation, but a control is identified. The variables are measured in an effort to gather evidence to support or not support a causal relationship. This is often called a controlled experiment.
    • * A fair test is conducted by making sure that only one factor (variable) is changed at a time, while keeping all other conditions the same.

In order for the ELL to meet grade-level learning expectations across foundation and enrichment curriculum, all instruction delivered in English must be linguistically accommodated (communicated, sequenced, and scaffolded) commensurate with the student's level of English language proficiency. For Kindergarten and Grade 1, certain of these student expectations do not apply until the student has reached the stage of generating original written text using a standard writing system. The student is expected to:
ELPS.c.5A learn relationships between sounds and letters of the English language to represent sounds when writing in English
ELPS.c.5B write using newly acquired basic vocabulary and content-based grade-level vocabulary
ELPS.c.5C spell familiar English words with increasing accuracy, and employ English spelling patterns and rules with increasing accuracy as more English is acquired
ELPS.c.5D edit writing for standard grammar and usage, including subject-verb agreement, pronoun agreement, and appropriate verb tenses commensurate with grade-level expectations as more English is acquired
ELPS.c.5E employ increasingly complex grammatical structures in content area writing commensurate with grade-level expectations, such as:
ELPS.c.5F write using a variety of grade-appropriate sentence lengths, patterns, and connecting words to combine phrases, clauses, and sentences in increasingly accurate ways as more English is acquired
ELPS.c.5G narrate, describe, and explain with increasing specificity and detail to fulfill content area writing needs as more English is acquired.
