The Development of the Atomic Model
Students trace the historical development of the atom from the plum pudding model to the Bohr model. They will analyse the evidence that led to changes in scientific theories.
About This Topic

Planning templates for Combined 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.

The Periodic Table
An exploration of how the periodic table is arranged by atomic number and electronic structure. Students will examine the properties of Group 1, Group 7, and Group 0 elements.

Chemical Bonds and States of Matter
Students investigate ionic, covalent, and metallic bonding, and how these bonds affect the physical properties of substances. The particle model is used to explain states of matter.
