Lesson 5: Unit 2 Review
Duration of Days: 2
Lesson Objective
How is matter organized at the atomic level, and how do these arrangements influence the properties of substances?
How is matter organized at the atomic level, and how do these arrangements influence the properties of substances?
Atom, proton, neutron, electron, ion, cation, anion, atomic number, mass number, isotope, nucleus, energy level
PS1.A: Structure and Properties of Matter. Each atom has a charged substructure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons.
DOK 1: Recall
Identify the three subatomic particles and their charges.
Define atomic number and mass number.
Distinguish between protons, neutrons, and electrons.
Label the parts of an atom in a diagram.
Calculate the number of protons, neutrons, and electrons in an atom given its atomic number and mass number.
DOK 2: Skill/Concept
Explain the concept of isotopes and their impact on atomic mass.
Interpret information from the periodic table to determine atomic structure.
Calculate average atomic mass from isotopic abundances.
Predict the electron configuration of elements.
DOK 3: Strategic Thinking
Analyze experimental evidence to support the existence of subatomic particles.
Use quantum mechanics to explain the behavior of electrons in atoms.
Differentiation by Content:
Tiered Assignments: Create assignments with varying levels of difficulty to cater to students' abilities. For example, offer a basic level assignment, an intermediate level assignment, and an advanced level assignment.
Flexible Grouping: Group students based on their readiness levels or learning styles. This allows you to provide targeted instruction and support to different groups of students.
Choice Boards: Offer students a variety of activities to choose from, allowing them to select tasks that align with their interests and learning styles.
Differentiation by Process:
Scaffolded Instruction: Break down complex tasks into smaller, manageable steps to support students who need additional guidance.
Graphic Organizers: Provide students with visual tools like Venn diagrams, concept maps, and timelines to help them organize information and make connections.
Technology Integration: Utilize technology tools like simulations, online resources, and educational apps to engage students and provide alternative learning pathways.
Differentiation by Product:
Multiple Assessment Options: Offer students a variety of ways to demonstrate their understanding, such as written reports, presentations, models, or digital projects.
Student Choice: Allow students to choose the format for their final projects, giving them ownership over their learning.
Rubrics: Develop clear and specific rubrics to provide students with expectations and guidelines for their work.
