Curated OER
Structure of the Atom
Students observe 3 models that show Dalton, Thomson and Rutherford's theories of the structure of the atom. In this structure of the atom lesson plan, students observe each model and write a summary of each theory of the atom.
Curated OER
The Atom
In this atom worksheet, students complete a 3 D graphic organizer for the structure of the atom. They define atomic structure, electron cloud, proton and neutron. They cut out the terms to make flaps with definitions.

Atomic Structure
A flashy PowerPoint includes clear summaries of atomic structure and electronic configuration. Dot and cross diagrams will help viewers learn how to draw an atom. As a result, learners should be more clear how electronic configuration...
Curated OER
Atomic Structure
Students explore atomic structure. They observe a video on atomic structure and complete a Venn diagram on the parts of the atom. Students create their own graphic organizer on the parts of the atom using Inspiration software.
