7Th Grade Science Unit 2: Matter And Energy In Chemical Changes

7th Grade Science Unit 2: Matter and Energy in Chemical Changes 2014-2015 Reporting Cluster: Physical and Chemical Changes Topic Knowledge: Assessments: Periodic Table 4 In addition to score 3.0 performance, the student demonstrates in-depth inferences and applications and Atomic that go beyond the target. Structure (semester 1) 3 Students demonstrate they have developed an understanding of: Proficient  that substances often are placed in categories or groups on the Periodic Table if they react in similar ways  use the periodic table to create a diagram of the structure of an atom and determine if it will bond with another element

2 Students will recognize or recall:

Specific vocabulary such as: atom, proton, neutron, electron, nucleus, energy level, atomic number, atomic mass, positive, negative, neutral, bond

Basic knowledge such as:

 use the periodic table to locate an element with specific characteristics  the reasoning for an element’s placement on the periodic table  the relationship between protons, neutrons and electrons  the atom as a basic building block of all matter

1 Student’s performance reflects insufficient progress towards foundational skills and knowledge. 7th Grade Science Unit 2: Matter and Energy in Chemical Changes 2014-2015 Reporting Cluster: Physical and Chemical Changes Topic Knowledge: Assessments: Chemical 4 In addition to score 3.0 performance, the student demonstrates in-depth inferences and applications Reactions that go beyond the target. (semester 2) 3 Students demonstrate they have developed an understanding of: Proficient  that substances react chemically with other substances in predictable ways to form new substances (compounds) which have different properties  that in physical changes and chemical reactions, atoms do not appear, disappear or change their identities  atoms may bond by giving, taking or sharing electrons with each other. Chemical reactions occur when the bonding arrangement among atoms changes, resulting in the change of reactant substances into products

2 Students will recognize or recall:

Specific vocabulary such as: electron, bond, reaction, chemical, conservation, mass, valance, matter, physical, reactant, product, energy, element, compound, substance

Basic knowledge such as:  the difference between a chemical and a physical change  in a chemical reaction, atoms gain, lose or share electrons  the signs a chemical reaction has taken place

I Can: Atomic structure and the Periodic Table  analyze and interpret the properties of products and reactants to determine if a chemical reaction has occurred

 interpret a model to determine if matter is or Chemical Reactions is not conserved in a chemical reaction, and explain the reasoning

 conduct an experiment to determine if energy is absorbed or released 7th Grade Science Unit 2: Matter and Energy in Chemical Changes 2014-2015
