Curated OER
Modern Physics, Old QT
In this physics worksheet, students develop an understanding of the atomic model and how atoms relate to one another through answering the seven questions.
Curated OER
VSEPR And Polarity
For this VSEPR theory worksheet, students evaluate the electron-pair geometry of organic and inorganic molecules. They construct Lewis structures and resonance structures for 17 compounds and complete 3 short answer questions.
Curated OER
Bonding
Students develop an understanding of covalent and intermolecular forces. They are also introduced to ionic bonds, bond length, bond energy, dipole moment, geometry, and Lewis Dot Structure. Students prepare a lecture about bonding...

A Model of a Scanning Tunneling Microscope
Ninth graders explain how a scanning tunneling microscope works. In this chemistry lesson, 9th graders construct atomic models and simulate how their images appear under the STM. They discuss the limitations of their atomic model.
Curated OER
Atom Models Through the Ages
Eighth graders explain the development of the atomic model over time. In this chemistry instructional activity, 8th graders research about the scientists who made a contribution to the atomic theory. They create a three-dimensional model...

Various Atomic Models
In this atomic models quiz worksheet, students complete an on-line quiz, clicking on questions and matching answers, scoring 1 point for each correct answer. A printed version is available.
Concord Consortium
Concord Consortium: Stem Resources: Atomic Structure
Introduces learners to atomic models of the past and present, focusing on the orbital model and an explanation of its basis. Learners then have the opportunity to "make an atom" and contrast it with an ion, followed by an isotope. The...
