How to use the Periodic Table
Summary of task
Students were asked to create a 'How to use the Periodic Table' guide which details the trends of the Periodic Table including the chemical background of one particular Group or Period. Students were asked to consider types of elements, ions and the electronic structure of atoms in their explanations. They were given the following questions to guide the discussion of their chosen group of elements:
- Why are the elements in the same row or column?
- What are the properties of the Group or Period?
- Why do the elements have similar properties?
Students were further asked to explain at least three uses in the real world of the elements within their chosen Group or Period and how our knowledge over time has influenced their usage. They were to assume that the completed guide could be given to a student as a learning aid.
Students worked individually on their 'how-to' guides over the course of several lessons and as homework. They were free to choose any digital medium they considered most suitable to convey the information, such as a poster, presentation, magazine article, pamphlet, comic book, interactive web-based solution, or video.
This task was given at the end of a teaching and learning unit on the structure and use of the Periodic Table of elements. As part of this unit, students revisited and deepened their understanding of the internal structure of atoms, learned about different types of elements and how to understand the symbols used to represent them. Students also learnt how the electronic structure of elements is the source of their similarities and differences, and how this is reflected in the structure of the Periodic Table.
