Transferable/Scientific Skills Developed
• To explain the inner structure of the Earth by means of some chemical basis • To link the properties of semiconductors to their position in the periodic table. • Appreciate that silicon, one of the important elements used in solar cells, is one of the most abundant elements in the earth crust.
o To make student aware that the periodic table is a chemical picture of the Universe, and that the element are letters of a chemical alphabet to construct every kind of animate or inanimate things in the universe.
o To improve the comprehension of the students that the semiconductors are a class of compounds which have a lot of interesting properties.
o To explain the great advantages in the application of semiconductors as principle elements used to “catch solar energy” in solar cells.
o To explain the huge importance of a responsible use of the Earth resources.
o To expand their vocabulary in the field related to earth science and ecological problems.
o To practice the impersonal language to speculate about scientific topics.
o To improve their listening skills.
o To increase their expertise to get useful information from a web site or a video.
Subject specific aims
o Earth science: to know the main features of the inside of the Earth and the relationship with the periodic table.
o to explain the relative abundance of the elements in the Earth crust and the relationship with their use.
o Chemistry: the teach the most important chemical features of the element in the periodic table related to the properties of semiconductors.
Target group age: 15-16
Level of competence in English.
Time required to use the resource with the students.
How to use it
o Watching the videos during the explanation of the periodic table, and promoting a peer assisted learning.
o To use the “new periodic table” to explain the inner structure of the Earth.
o To use the “new periodic table” to improve a discussion about the link between quantity and need of some element in the Earth crust.
o Trough the cooperative learning, to lead a discussion, between small groups of students, focused on the wrongful use of natural resources and the link with their different abundance into the Earth.
Possible difficulties for the students.
o To find a correlation between a lot of different things and a relative small number of element.
o To understand the link between chemical structure and the properties of the semiconductors.
o To link an element on the periodic table to a mineral, and its specific application related to its chemical proprieties.
o To understand the strict connection between their daily habits and the right and conscious use of the elements of the periodic table.
Strength The student could develop their personal idea about the conscious use of energy related to the use of some elements in the Earth crust. They could achieve a better knowledge about the “chemical relationship” between their everyday life and the component of the environment, and how to use them in a better way. • Weakness The scientific concept related to the technology of the renewable energy can be complex even though the students don’t have much chemical and physical competences. They could have some difficulty to find a connection between their life experience and the problem of the bad use of Earth resource. The inner structure of the Earth includes all the elements necessary to produce energy. They can be used in a not renewable way or in an ecological and more conscious way. The chemical basis can be difficult to explain and understand, but the cleanness of the solar energy can be fascinating. Pedagogical value After the explanation of some theorical basis related to the web resource, the students should build their own knowledge about a part of the topic, working in small group and comparing their research to that of the other in a collaborative learning way.
