DESCRIPTION
The prerequisites
The periodic table could be consulted in different steps of the curriculum; a student that can manage the macroscopic model of the matter is however able to understand the concepts about the classification of simple substances at the macroscopic level. When the student gradually learns working with atomic-molecular models and core electronic, he will have access to a quality and a quantity of notions more and more higher.

The contents
The amount of notions provided by the site involves a considerable variety of chemical concepts. They range from the simple density of substances (macroscopic quantity) to the electronic configurations attributed to neutral atoms (microscopic properties). Particular evidence is given, as it should be, at the chemical transformations of simple substances.

The aims
The information that can be found in this Periodic Table allow to reason about the criteria which are the source of this great and unique classification. This purpose, is also emphasized by the historical development of the Periodic Table.

Task Description
The use of this reference tool depends on the teaching approach that a teacher decides to adopt. The abundance and variety of notions allows to not use this table like a simple reservoir of information.

How to use it in class
As an example, it would be appropriate to exploit this tool in order to enable students to distinguish the properties of simple substances from the attributes that define the concept of chemical element.
COMMENTS
Points of strenght
The movies about the chemical transformations are particularly appreciable, which are difficult to do in the classroom. They are not only curious, but they could be used as a problematic situation.The links are noticeable to other site about the same subject.

Points of weakness
The concepts of simple substance and element are not explicitly distincted

Scientific reliability
Hight

Pedagogic value
It should be pointed out that the didactic transposition of knowledge contained in this site depends on the model of learning and didactic approach chosen by the teacher. Certainly the knowledges of discipline which may be disposed in this Periodic Table are a scientific point of a good standard.

Message: The structure and organization of the Periodic Table of Elements available in this website constitutes a very important pedagogical tool, privileging a simplified and fast access to several chemical concepts. The teacher can propose to students, exploration tasks based on the existing portal contents. From the analysis and treatment of the collected data, students are able to acquire competences to relate element position with its physical and chemical properties.
The presented experimental activities based on a video/film platform assume a huge importance since they can surpass the inexistence of equipment and laboratorial conditions in several schools. Moreover, they contribute to enhance motivation and learn outcomes, helping to understand elements chemical/physical transformations. From this starting point the teacher can lead students to establish relationships between microscopic and macroscopic properties.
In my opinion it would be interesting to upgrade the site in order to include subjects such as variation in ionization energy and electron affinity, which are subjects of recognized difficulty for students.

National Reports on successful experiences to promote lifelong learning for chemistry The national reports on chemistry successful experiences to promote lifelong learning for chemistry are now available on the related section of the project portal. The reports presents examples of successful experiences in the partner countries and the results of testing of ICT resources with science teachers.
