Periodic Table Club, Makayla Gill, Kailynn Jensen

Honors Expanded Learning Clubs

This club is dedicated to teaching the generation of future scientists the periodic table. This is designed to be a unique take on a STEM club that uses the periodic table as a backbone for a solid foundation in chemistry.

------------

The following provides a brief introduction to the application of ozonolysis within academic labs. Ozonolysis remains among the most frequently used of methods for oxidative cleavage of alkenes. While best known as a means by which to introduce aldehydes and ketones, ozonolysis can also be used to generate other …

Twitter can be used to promote chemists, their work, and their events to other scientists and the general public. From checklists to timelines; how to use Twitter successfully as an individual or institution is discussed. This chapter includes: examples of how the authors have used Twitter, how to find and use common subject tags, tags most used when Tweeting about chemistry and science, and a discussion about measuring success. Knowing when and how to Tweet will help chemists communicate successfully with their peers and the general public in 280 characters or less.
