Sakis Tsechpenakis
Mykonos Junior High School
Teacher involved
Learn Chemistry (Chemistry for the Gifted and Talented: Atoms, elements, molecules, compounds and mixtures)
Topics related to the resource
1. Electrolysis of water
2. Differences between molecules of chemical elements and molecules of chemical compounds
3. Introduction to the concept of molecular formula (for water)
4. Fuel cells, as a possible energy source in the future
Examples of learning objectives
The resource is used as an exercise at home to evaluate if the students are able to differentiate chemical compounds, chemical elements and mixtures.
Practical information regarding the use
of the site/simulation...
It is downloadable material. The pages of the worksheet were translated into Greek and were given to the students at the end of the class, as a home exercise.
Information about the class
The resource was tested in Mykonos Junior High school (lower secondary school) on February 2014, during one teaching hour, in the presence of science teachers from nearby schools. The class consisted of 25 students between 13-14 years old (2nd grade of lower secondary school). The science school advisor of Cyclades islands was physically present and evaluated the course. The course was also viewed by science teachers from the islands Amorgos, Iraklia and Donousa via video conference.
Suggestion for use
1. The students were given a worksheet at the beginning of the class.
2. An electrolysis apparatus was used to demonstrate the production of hydrogen and oxygen from water. Subsequently, conversation between the students concerning the process and the expected products took place.
3. After the electrolysis, two three-minute “youtube” videos were projected to demonstrate the use of hydrogen fuel cells.
4. Finally a worksheet that contained Venn diagrams, was given to the students, in order to evaluate the degree of their understanding of the differences between chemical elements and compounds. This worksheet was given to the students as a home exercise.
Insights into student
use / thinking
A short (a few minutes) introduction is needed, in order for the students to understand the use of the Venn diagrams. When they actually get the grip on the concept, they actually enjoy Venn diagrams, as it is a new way of putting data in different categories.
Teacher’s conclusions
Students enjoyed it, and I enjoyed it too. Venn diagrams is a good way to categorize data, without the use of charts and tables. I was contacted by fellow teachers from other schools of Cyclades complex, who found the use of Venn diagrams in this class a very innovative idea.

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.
