8.2C-E8.5: Matter and energy. The student knows that matter is composed of atoms and has chemical and physical properties. The student is expected to:
8.5D recognize that chemical formulas are used to identify substances and determine the number of atoms of each element in chemical formulas containing subscripts
8.5F recognize whether a chemical equation containing coefficients is balanced or not and how that relates to the law of conservation of mass

6TH GRADE
•6.5A know that an element is a pure substance represented by chemical symbols
•6.5C differentiate between elements and compounds on the most basic level
8TH GRADE
8.5: Matter and energy. The student knows that matter is composed of atoms and has chemical and physical properties. The student is expected to:
8.5D recognize that chemical formulas are used to identify substances and determine the number of atoms of each element in chemical formulas containing subscripts
8.5F recognize whether a chemical equation containing coefficients is balanced or not and how that relates to the law of conservation of mass
CHEMISTRY
•C.8D: use the law of conservation of mass to write and balance chemical equations
• Elements can be identified using their chemical symbol.
• A compound is composed of two or more elements with different properties than the individual elements.
• Compounds are represented by chemical formulas.
PRIOR LEARNINGH stands for hydrogen.
The O stands for oxygen. It has no number after it. That means there is only one oxygen atom.
The 2 after the H shows that there are two hydrogen atoms.

Based on the data and distractors, what key points should teachers emphasize during lessons?
• The subscript is located after the element it represents.
The 2 after the H shows that there are two hydrogen atoms.
Based on the data and distractors, what key points should teachers emphasize during lessons?
• When an element does not have a subscript, there is one atom of the element.
• Encourage students to mark a 1 next to any elements without a subscript as a reminder.
• NO SUBSCRIPT = 1
The O stands for oxygen. It has no number after it. That means there is only one oxygen atom.
Based on the data and distractors, what key points should teachers emphasize during lessons?
• Each chemical formula (without a coefficient) represents a molecule of the compound.
• A chemical equation provides the number of molecules involved in the chemical reaction.
Chemical Formula = # of Atoms of Each Element of a Molecule
Based on the data and distractors, what key points should teachers emphasize during lessons?
• Students can lack persistence when recognizing balanced equations.
• Build student endurance with numerous examples and a simple strategy for breaking down the equation.
C = 12 C = 6
STOP! NOT BALANCED
C = 6O = 12 + 6 = 18
H = 12
C = 6O = 6 + 12 = 18H = 12
BALANCED
Components of a good lesson plan

2. Review/Scaffold to TEKS
3. Student-Centered Activities directly relating to the depth and complexity of the TEKS
• Labs, Activities, Videos
1. Organize and Practice Vocabulary
2. Reading & Comprehension Strategies
3. Writing Opportunities & Scaffolds
4. Daily Listening & Speaking Opportunities
5. Differentiation
6. Formative Assessment & Reteach

Higher level questions• “Research shows there’s a link between critical thinking skills and increased student achievement in the
classroom.” (Moore & Stanley, 2010)
• Higher level questions must be planned in order to be implemented effectively in the classroom.
• Levels of Questions
• Knowledge
• Comprehension
• Application
• Analysis
• Synthesis
• Evaluation
• Plan and provide a variety of questions at each level and build student knowledge and critical thinking by providing Higher Level Questions.

• “Word walls can be arranged on cupboard doors or classroom walls, or hung from the ceiling with wire and string.”
• “Maximum instructional potential and efficiency are achieved when interactive word-wall construction is aligned with lessons and students are allowed to participate in the process. As a result, walls are usually built over many days and are finished as a unit nears completion. Word walls support units and are changed or replaced as units change.”
