Nora Walsh outlines the interactive notebook pages she uses for her unit on Atomic Structure. All of the documents and foldables are available for download.
Atomic Structure / Theory
A continuation of Counting Orbitals I: The 'Ah-ha! Moment' and Quantum Numbers. Sit back and adjust your eyeballs for some colorful graphics.
A kaleidocycle is presented in which the entire periodic table has been collected. In this three-dimensional figure are the elements organized in four blocks according to their final electronic structure. It is intended that students with this playful figure actively participate in classes by rotating their kaleidocycle looking for the groups or elements that are being studied. The entire periodic table fits in one palm of their hands. It is also a didactic device because students only focus their attention on one block or group of elements from the entire Periodic Table. It can be achieved a more entertaining, motivating and exciting learning about the subject of the Periodic Table.
Using guided inquiry learning to identify patterns and trends in the Quantum Mechanical Models of elements.
A new lesson that uses PES evidence to drive the instruction that would allow the students to identify the limitations of the Bohr model and introduce the Quantum Mechanical Model .
Atomic theory is a common topic throughout any introductory chemistry course. It is likely that Rutherford’s gold foil experiment gets at least some attention in your course. This simple activity gives students an opportunity to replicate Rutherford’s experiment through an analogy experiment that may allow for easier conceptualization of the experiment itself and provide additional support for model development.
Quantum mechanics is a proverbially and quintessentially challenging topic. It is the poster-child of difficulty in chemistry. Setting up the discussion for the four quantum numbers is fraught with potential and confusion. In this post learn about a different way to teach about orbitals.
Whether in the classroom or in the online format, students typically struggle to envision the infamous Rutherford (aka Geiger-Marsden) gold foil experiment. A short video was created that describes the experimental design and set up. Enjoy...
Card sorts can be used to quickly assess student understanding. The author has modified two card sorts on photoelectron spectroscopy and intermoleculer forces for use either remotely or in a paperless classroom.
Germany issued a pair of stamps that honor two fundamentally huge accomplishments in science in 1994. The Quantum Theory and Ohm’s Law. They were really well designed stamps and very accurate in their science.
