This lab assessment is a wet lab that has students use lab skills to demonstrate their knowledge of polarity, Lewis structures, solubility, and intermolecular forces by justifying the polarity of given compounds.
HS-PS1-1 Using the Periodic Table
Use coding for a new twist on a classic element project. See how easy coding can be and consider the applications of coding in your own classroom.
Josh Kenney shares three simple and inexpensive demonstrations using Elmer’s glue.
Javalab is a resource for free simulations to support student understanding of chemistry concepts. These web based simulations can be used across different platforms and are simple in their use by students. The open ended aspect of the simulations allow for teachers to be creative in how they are used in class.
Ordinary playing cards can be used in games where the cards model valence electrons in atoms. These games could provide players with a fun and active way to practice counting valence electrons in simple chemical structures.
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.
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.
