2nd Six Weeks Planner (24 days)

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.


• 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.


• 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


• 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

1. Engage Student Interest

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.

•Interactive Word Wall- Current, working models with student contributions • Interactive Word Walls Article: http://learningcenter.nsta.org/files/ss1103_45.pdf

• “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.”
