1 8.5 The student knows that matter is composed of atoms and has chemical and physical properties. 8.5D that chemical formulas are used to identify substances and determine the number of atoms of each element in chemical formulas containing subscripts. CHEMICAL FORMULAS USES GRADE 8 Unit 04: Chemical Formulas, Equations and Reactions 2010 TEKS 1998 TEKS Curriculum and Instruction Considerations 8.8 The student knows that matter is composed of atoms. identify substances determine the number of atoms of each element VII. Chemistry H2 Understand energy changes and chemical s. 8.9C the importance of formulas and equations to express what happens in a chemical. IMPORTANCE OF FORMULAS AND EQUATIONS IN REPRESENTING CHEMICAL REACTIONS law of conservation of mass Note: Students understand that chemical s represent the rearrangement of elements. Students are NOT required to balance equations. 7.7A Identify and demonstrate everyday examples of chemical phenomena such as rusting and tarnishing of metals and burning of wood. Identify, EXAMPLES OF CHEMICAL PHENOMENA Use 8 th grade, Unit 3 Lesson 1 Engage Use page 3 Omit -It s in the Bag Part A & B pages 4-5. Omit or modify page 5. Teacher may want to describe what exothermic and endothermic mean.
