Texas Essential Knowledge and Skills for Science
Knowledge and skills. 

(1)	Scientific processes. The student is expected to: (A) demonstrate safe practices during field and laboratory investigations; and  (B) make wise choices in the use and conservation of resources and the disposal or recycling of materials.

(2)

Scientific processes. The student uses scientific methods during field and laboratory investigations. The student is expected to: (A) plan and implement investigative procedures including asking questions, formulating testable hypotheses, and selecting equipment and technology;  (B) collect data and make measurements with precision; (C) express and manipulate chemical quantities using scientific conventions and mathematical procedures such as dimensional analysis, scientific notation, and significant figures; (D) organize, analyze, evaluate, make inferences, and predict trends from data; and  (E) communicate valid conclusions.

(4)

Science concepts. The student knows the characteristics of matter. The student is expected to:    (A) differentiate between physical and chemical properties of matter;  (B) analyze examples of solids, liquids, and gases to determine their compressibility, structure, motion of particles, shape, and volume; (C) investigate and identify properties of mixtures and pure substances; and (D) describe the physical and chemical characteristics of an element using the periodic table and make inferences about its chemical behavior.

(5)

Science concepts. The student knows that energy transformations occur during physical or chemical changes in matter. The student is expected to:   (A) identify changes in matter, determine the nature of the change, and examine the forms of energy involved;  (B) identify and measure energy transformations and exchanges involved in chemical reactions; and  (C) measure the effects of the gain or loss of heat energy on the properties of solids, liquids, and gases.

(11)

Science concepts. The student knows that balanced chemical equations are used to interpret and describe the interactions of matter. The student is expected to:  (A) identify common elements and compounds using scientific nomenclature;  (B) demonstrate the use of symbols, formulas, and equations in describing interactions of matter such as chemical and nuclear reactions; and (C) explain and balance chemical and nuclear equations using number of atoms, masses, and charge.

Student Objectives
Students will be able to:

• Recognize the components of a chemical reaction  
• Analyze the products formed by a reaction  
• Predict the products formed by a set of reactants  
• Conduct laboratory investigations to develop and evaluate understanding of reaction types
