Three-dimensional figure to improve the didactics of the Periodic Table
PABLO CASSINELLO | Mon, 04/04/2022 - 10:00
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.

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 .
Analogy Experiment—Projectile Pennies with Rutherford
Ben Meacham | Mon, 11/08/2021 - 15:48
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.

How I Fell in Love with PES
Melissa Hemling | Mon, 02/25/2019 - 19:28
Like many AP Chemistry teachers, Melissa Hemling was not fond of teaching Photoelectron Spectroscopy (PES). Surprisingly, she fell in love with teaching PES in AP Chemistry after making an old-school change.
Types of Ionizing Radiation Lab and Simulation
Lauren Stewart | Fri, 04/27/2018 - 19:28
As many teachers are preparing for the possibility of teaching online next semester, we are revisiting posts from the ChemEd X archives like this one that might be of help. The author has updated this activity by adding notes specifically to help those teaching remotely. - Radioactivity is a topic in chemistry that can be difficult to teach. This activity offers a data-driven approach with a simulation students can use in school or in an online learning environment. This can be used to give students an authentic lab experience for them to determine there are three types of ionizing radiation without direct instruction.
Mass Spectrometer Model

My students just finished an activity about isotopes. Each year there is always one or more student who ask about the mass of isotopes. How do scientists solve for that mass experimentally?
