Curated OER
Why Do Atoms Combine?
In this atom worksheet, students will complete 8 fill in the blank statements based on the different parts of an atom. Then students will explain how the arrangement of electrons in an atom is related to the periodic table.

Physicists or Philosophers?
Trace the sequential process of the developing theories of atomic structure in the early 20th century, show, in historical development, how scientists "know" things, how experiments are set up and how interpretations are drawn from them,...
Curated OER
Atomic structure - Historical background
Students use the Internet to research the development of the discovery of the atom. They create an essay, PowerPoint presentation and a story line on the subject.
Curated OER
Basic Chemistry Review
Students experiment to show their knowledge of molecules and atomic structures. In this chemistry review lesson students participate in an activity and then fill out a worksheet.
Curated OER
Discovering the Structure of the Atom
Students investigate atomic and nuclear structure of matter by researching historical atomic theories. Students examine Rutherford's studies and discover that many scientific conclusions change over time as new data is collected.
Curated OER
Kinetics and Equilibrium
Students develop an understanding of what a reaction is and factors that affect it. They are introduced to: reaction mechanisms, reaction rates, reaction order, factors affecting reaction rates, Le Chatelier's Principle and Equilibrium.
