The 1920’s started with a long shadow of destruction from World War 1 and ended with the start of the Great Depression in 1929. The majority of the decade was characterized by a large migration of people living on farms to cities; and a new music and dance wave edged on by the increased popularity of the radio. This freedom of choice transcended to Science fiction such as the Made Planet by Murray Leinster (1920) to the Master Mind of Mars by Edgar Burroughs (1928). Sci Fi at that time often converted current events (i.e. WW1) into symbols such as the destruction of civilization by different forces. There has always been a connection between young students being inspired by Sci Fi and their career choice.
This decade also saw the large-scale implementation of cars, trucks, airplanes, motion pictures, etc. into society. Along with those new products there was an increase in students entering STEM fields and new job markets being created that had never existed. The ability to mass produce products for society made the world smaller and the demand for new concepts and inventions in science and technology a priority. Mass production also resulted in engineers and scientists from different fields working closely; from producing metallic iron from iron ore to using arsenic on a large scale as a pesticide in agriculture to new medications. By the end of the 1920's, the experimental discovery of the neutron was not achieved, and the first large scale production and distribution of an antibiotic (penicillin) was still more than a decade away.

The Nobel Prize is awarded every year in six disciplines; Chemistry, Physics, Medicine and Physiology, Literature, Peace, and Economics. Alfred Nobel, active as an inventor and businessperson, left a will in 1895, to acknowledge "those who, during the preceding year, have conferred the greatest benefit to humankind." Scientists can typically spend years or even decades developing their projects that can advance humanity. Once the concept or event has been brought into the public’s view, its impact is evaluated. The announcements of the year’s recipients take place in the fall of each year, with a ceremony held in Sweden typically in early December. The award includes a gold medallion, a diploma, and a significant monetary award. Awards are often correlated with popularity, as many Nobel Awards winners have been known to shape our society, from Watson and Cricks double helix structure of DNA and Marie Curie's work with radioactivity, to Jennifer Anne Soudan and Emmanuelle Charpentier work with CRISPR and Carolyn Bertozzi, Morten Meldal and Barry Sharpless (his 2nd Nobel Prize) for their work with click chemistry. We are working on a series of puzzles that will provide some introductory material on every Nobel Prize awarded from 1901 to 2022. In addition, some key concepts in the Nobel Award in medicine and physics with strong links to various areas of chemistry will also be included. These will range from Watson and Cricks model of DNA to the Bohr model of the atom.
Our first educational puzzle submitted to ChemEd X was developed during the pandemic and focused on infectious diseases (see Using an Abbreviation Puzzle as a Method to Familiarize Students with Infectious Diseases)1. It allows players to learn something about over 150 infectious diseases using a strategic method.
Recently we developed a novel puzzle that allows students to think strategically while familiarizing themselves with the elements and their symbols from the periodic table (see Turning Element Abbreviations into a Strategic Exercise). Read this post for more information about the educational benefits of using puzzles.
This series of puzzles can be completed individually or in groups, and it can be used in a classroom setting or given as homework. And don’t forget, there are always a few parents and other family members that might enjoy the activity.
