A student expectation is directly related to the knowledge and skills statement, is more specific about how students demonstrate their learning, and always begins with a verb. Student expectations are further broken down into their component parts, often referred to as “breakouts.”
A knowledge and skills statement is a broad statement of what students must know and be able to do. It generally begins with a learning strand and ends with the phrase “The student is expected to:” Knowledge and skills statements always include related student expectations.
Further Explanation
Below is a pH scale from zero to fourteen with examples of solutions at each interval. Solutions listed with pH less than 7 are acids. Solutions listed with a pH greater than 7 are bases.
Glossary Support for S.8.6.D
any substance that in aqueous (water) solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, promotes chemical reactions (acid catalysis), and has a pH less than 7
any substance that in aqueous (water) solution is slippery to the touch, tastes bitter, changes the color of indicators (e.g., turns red litmus paper blue), reacts with acids to form salts, promotes certain chemical reactions (base catalysis), and has a pH greater than 7
a type of change in which a new substance is made from one or more previous substances; occurs during a chemical reaction; a change where the atoms of the original substances are rearranged to make new elements and/or compounds
a physical system that does not allow transfer of matter in or out, although energy can flow into and out of the system
the smallest particles of matter that have distinct physical and chemical properties; consist of a nucleus which contains protons and neutrons and an electron cloud which contains electrons
a measure of acidity and alkalinity of a solution that is a number on a scale from 0-14 where 7 represents a neutral solution, lower numbers indicate increasing acidity, and higher numbers indicate a base; a measure of the relative amount of free hydrogen (H+) and hydroxyl (OH-) ions in the water
observable characteristics of matter that can be used to identify particular materials
Summary: Using the 5E model of learning (Engage, Explore, Explain, Elaborate, and Evaluate,)"Indicators for Inquiry "asks students to create their own pH indicator and use it to investigate the pH property of liquids or solutions and determine whether the substance is an acid, base or is neutral.
