8th Grade Lesson Plans: 2nd Six Weeks

CHEMICAL REACTIONS – CHAPTER 4

 

TEKS OBJECTIVES:

 

(5)  Matter and energy. The student knows that matter is composed of atoms and has chemical and physical properties. The student is expected to:

 

(D)  recognize that chemical formulas are used to identify substances and determine the number of atoms of each element in chemical formulas containing subscripts;

 

(E)  investigate how evidence of chemical reactions indicate that new substances with different properties are formed; and

 

(F)  recognize whether a chemical equation containing coefficients is balanced or not and how that relates to the law of conservation of mass.

Sept. 30 – Oct. 7, 2011

– Chemical symbols, formulas, and subscripts-Chapter 4-Sec. 1 Chemical Formulas and Equations

– The parts of a chemical equation and signs that a chemical reaction is taking place-Chapter 4-Sec. 1 Chemical Formulas and Equations

– The Law of Conservation of Mass and recognizing balanced equations with subscripts and coefficients-Chapter 4-Sec. 1 Chemical Formulas and Equations

NEWTON’S LAWS OF MOTION – CHAPTER 6

 

 

TEKS OBJECTIVES:

 

(6)  Force, motion, and energy. The student knows that there is a relationship between force, motion, and energy. The student is expected to:

 

(A)  demonstrate and calculate how unbalanced forces change the speed or direction of an object’s motion;

 

(B)  differentiate between speed, velocity, and acceleration;

(C)  investigate and describe applications of Newton’s law of inertia, law of force and acceleration, and law of action-reaction such as in vehicle restraints, sports activities, amusement park rides, Earth’s tectonic activities, and rocket launches.

 

 

Oct. 11 – Nov. 3, 2011

– Balanced and unbalanced forces, speed, direction; Sir Isaac’s 1st Law of Motion on inertia-Chapter 6-Sec.1 Motion and Sec. 2 Newton’s First Law

– Calculating speed, velocity, and acceleration; Newton’s 2nd Law of Motion on forces and acceleration-Chapter 6-Sec. 1 Motion and Sec. 3 Newton’s Second Law

– Newton’s 3rd Law of Motion on force pairs; explain and give examples (give every day examples plus geologic processes and astronomical phenomena) of Newton’s 3 laws of motion- Chapter 6-Sec. 4 Newton’s Third Law

– Project:  Construct moving models of one of Newton’s laws of motion.  Present model to the class with explanation of how the model relates to the law.  Extra credit given for a video made by the student.

October 17 (Maroon Day) and October 20 (White Day)

View and discuss an antibullying video.  Emphasize the Golden Rule.

2nd SIX WEEKS PROJECTS DUE: Oct. 25

SECOND SIX WEEKS TEST:  Nov. 2/3

Six Weeks Test will be over TEKS objectives 5-D, E, F on chemical reactions and the Periodic Table  and TEKS objectives 6-A,B,C on Newton’s Laws of Motion.   Study all notes and review worksheets.  Extra credit will be given if parents sign the test review.

INSIDE THE ATOM – CHAPTER 2

TEKS OBJECTIVES:
(5) Matter and energy. The student knows that matter is composed of atoms and has chemical and physical properties.
The student is expected to:
(A) describe the structure of atoms, including the masses, electrical charges, and locations, of protons and neutrons in
the nucleus and electrons in the electron cloud;
(B) identify that protons determine an element’s identity and valence electrons determine its chemical properties,
including reactivity;
(C) interpret the arrangement of the Periodic Table, including groups and periods, to explain how properties are used to classify elements.
