Groups and Periods: Trends in Reactivity
Students will identify groups and periods on the Periodic Table and analyze trends in reactivity and properties for alkali metals, halogens, and noble gases.
Key Questions
- Compare the reactivity of elements within the same group.
- Explain how electron configuration influences an element's position and properties.
- Predict the properties of an unknown element based on its position in the Periodic Table.

Planning templates for Science
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
rubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.

States of Matter and Particle Model
Students will describe the properties of solids, liquids, and gases using the particle model, explaining changes of state.

Inside the Atom: Protons, Neutrons, Electrons
Students will identify the subatomic particles within an atom, understanding their charges, masses, and locations.
2 methodologies
Atomic Number and Mass Number
Students will identify the atomic number as the number of protons and the mass number as the sum of protons and neutrons, without detailed calculations for isotopes.
2 methodologies
Electron Shells and Reactivity
Students will understand that electrons occupy shells around the nucleus and that the number of outer shell electrons determines an element's reactivity.

The History of the Periodic Table
Students will explore the historical development of the Periodic Table, recognizing the contributions of scientists like Mendeleev and the rationale behind its organization.
