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.
Key Questions
- Explain how electrons are arranged in shells around the nucleus.
- Analyze the relationship between outer shell electrons and an element's chemical behaviour.
- Predict the relative reactivity of elements based on their electron configuration.

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.

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.
