The panther is a symbol of courage, valor, and power.

"Everyday courage has few witnesses. But yours is no less noble because no drum beats for you and no crowds shout your name." - Robert Louis Stevenson (1850 - 1894), Scottish Novelist, Poet, and Essayist

"Valor is a gift. Those having it never know for sure whether they have it till the test comes. And those having it in one test never know for sure if they will have it when the next test comes." - Napoleon Bonaparte (1769 - 1821), Military and Political Leader of France

“Never underestimate the power of a good night’s sleep.” –Pam Beasley, The Office

1st Semester Past Units

1.2 Atoms & Periodic Table

Unit Overview:

Topic 1: Inside the Atom Students will need to know where each subatomic particle is located, and the mass and charge of each of these particles. Also, students will have to explain the properties of the nucleus and the electron cloud based on the properties of the subatomic particles that each part holds. They will use the periodic table to determine the number of protons, neutrons, and electrons of each atom using Atomic Mass and Atomic Number. They will need to know that protons determine an atoms identity.
Topic 2: Valence Electrons and ReactivityStudents will need to understand what a valence electron is, where it is found, and how we can determine this using the periodic table. They will have to determine which elements would likely bond with other elements on the table. They have to understand that the number of valence electrons determines whether an element is not reactive, slightly reactive, or highly reactive. They will need to know that valence electrons determine an atoms reactivity.
Topic 3: Periodic TableStudents will need to use the periodic table to determine the properties of elements. They will have to recognize the patterns within the structure of the elements as we move across and down the table. They have to recognize periods and groups and use this information to determine an unknown atom.

Unit Overview

1.3 Chemical Reactions Unit Guide1.3 Topics and Skills

Topic 1 Formulas and Equations

Identify the parts of chemical formulas and equations, such as elements, compounds, atoms, molecules, reactants, products, subscripts, and coefficients. Count the total number of atoms and the number of atoms for each element in a chemical formula with subscripts and coefficients.Describe the law of the conservation of mass and recognize when it is being demonstrated by a chemical equation.Analyze unbalanced chemical equations to identify an error.

Topic 2 Chemical Reactions

Describe the difference between physical and chemical changes. Recognize the signs that a new substance has formed.Analyze the results of an experiment to explain the evidence that a new substance has formed.Explain how the law of conservation so mass relates to the forming of a new substance during a chemical reaction.
