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)
