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.
HS-PS1-1 Using the Periodic Table
In this ChemBasics Talk, Rachmad Tjachyadi offers everything necessary to plan a unit on the topic of the periodic table and periodic trends including linked NGSS standards, introductory activities and handouts, manipulative activities, practice problems, links to real world context, a lab and an assortment of videos. Watch the recording and access resources he shared.
Many novice students struggle to see elements' valence electron configuration trends across the rows and columns on the periodic table. There are many diagrams and explanations available as resources for students however, a deeper understanding may be possible when students discover these trends independently through a game called Electron Configuration Battleship.
This virtual adaptation provides students the opportunity to engage in a process similar to the one Mendeleev used as he constructed the original version of the periodic table we still use today.
In this lesson, students are offered a variety of alternative versions of the periodic table. Students will identify trends that are consistent from one table to the next in order to understand why the tables they are working with and Mendeleev's version are organized in the manner that they are. This lesson was designed to fit the NGSS performance expectation HS-PS 1.1 but can be used for any first year chemistry course or modified at your discretion.
In honor of the International Year of the Periodic Table: A familiarity with the chemistry of some of the elements more commonly encountered in everyday life is a valuable learning experience for all students. Iodine is the fifth in this series of elements to be discussed as part of the Element of the Month program. #IYPT
Trends related to placement of elements on the periodic table are often taught using diagrams in a textbook. Students often memorize trends, but to get a true grasp of their meaning and what causes certain patterns is best understood when students create their own models and discuss the patterns with others.
This five puzzle mystery aligns with my chemistry curriculum after instruction on the properties of elements and electron configurations. I use this mystery as a review to prepare for assessments over the properties of elements, symbols on the periodic table and the difference between groups and periods. Also incorporated within the puzzles are basic trends such as the number of subatomic particles, mass number, melting point, and other characteristics of specific elements.
This past March, I ran a multi-day poll on Twitter that was designed to be a fun way to determine the “best” element on the periodic table. I’m sharing about the poll here on ChemEdX in case others might want to try something similar in their classrooms.
Do you require your students to learn all the element names and symbols? Do your students struggle with chemical nomenclature, chemical equations, or stoichiometry? You may want to consider getting them back to the basics.
