Segment E: Chemical Reactions Review
Segment E: Chemical Reactions Review
We see how students learned to recognize the signs of chemical change in this recap of Unit 5, "Chemical Reactions." The unit also covered the Law of the Conservation of Matter, and students balanced chemical equations and learned to draw models representing those equations.
Science
Obtain, evaluate, and communicate information about the use of the modern atomic theory and periodic law to explain the characteristics of atoms and elements.
Construct an explanation of light emission and the movement of electrons to identify elements.
Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms (i.e. including atomic radii, ionization energy, and electronegativity).
Obtain, evaluate, and communicate information to support the Law of Conservation of Matter.
Plan and carry out investigations to generate evidence supporting the claim that mass is conserved during a chemical reaction.
Develop and use a model of a chemical equation to illustrate how the total number of atoms is conserved during a chemical reaction.
Obtain, evaluate, and communicate information about the structure and properties of matter.
Construct an explanation based on evidence to describe conservation of matter in a chemical reaction including the resulting differences between products and reactants.
The Chemistry Matters teacher toolkit provides instructions and answer keys for labs, experiments, and assignments for all 12 units of study. GPB offers the teacher toolkit at no cost to Georgia educators. Complete and submit this form to request the teacher toolkit. You only need to submit this form one time to get materials for all 12 units of study.
