Green week was celebrated between the 20th and the 24th May 2013 in connection with the ERDF (European Regional Development Fund) 228 Project called GREEN ENERGY SCHOOLS. The principal aim of the project is the implementation of Renewable Energy technology to increase clean energy sources and improving the environment. 13 Church schools are participating in this project.

These are the activities that were done during this week:

EUROPEAN STUDIES

Eight students who study European Studies took part in green week by putting up visual presentations on renewable energy. They worked in Groups of two and each group had to prepare a presentation on renewable energy. Mainly the presentations explained the geothermal, sun, wind and solar energy. Furthermore, these presentations highlighted some of the advantages and disadvantages these sources of clean energy have.

ENVIRONMENTAL STUDIES

During Environmental Studies lessons, as part of the Form 4 syllabus, students learned about the difference between renewable energy and non-renewable energy sources, including the advantages and disadvantages for both. Further insight was given on the various types of renewable sources of energy, focusing especially on those that could be possible in Malta – Solar energy and Wind energy.

Students were also informed about the European Union targets for Malta as regards this issue. The country should obtain 10% of its energy from renewable sources by 2020. As a follow up, a discussion/role play was carried out during the ERDF Green Week. It encouraged students to take different roles such as an environmental officer, a project developer, a local council member, an ornithologist (bird specialist) to see whether they agree or disagree about the proposed offshore wind farm at is-Sikka l-Bajda in Mellieha. This activity initiated students to think about the pros and cons of such project in Malta as a strategy to reach the set targets by the European Union.

A stand with charts and a model was also put up in the school corridor displaying the students’ work which was based on research about one of the following:

• The advantages of the renewable energy over non-renewable sources of energy.
• The benefits of solar energy
• The benefits of wind energy
• What makes an ideal site for a wind farm?

All this helped in creating more awareness amongst our students as regards renewable energy especially in the light of the ERDF funds given to our school to install the photovoltaic cells.

MATHEMATICS

Duration of lesson: 40 Minutes
Aim: Creating pie charts and bar charts

The class was divided in 3 groups (red/green/yellow) with 3 or 4 students in each group. Each student was given a ‘role card’ (Representative/ Speaker/ Coordinator/ Recorder). The groups were given a hand out each with a table with different data. (Refer to hand out below)

Group 1: Number of panels installed in schools
Group 2: Actual power installed
Group 3: Units generated per year

Students were given 15 minutes to insert the data on the excel sheet and to create a pie chart and a bar chart.

The data was then saved on a pen drive and the pie charts and bar charts were copied on the teacher’s laptop. The speakers of each group had to explain to the rest of the class what their pie chart and bar chart was about.

At the end of the lesson, the teacher explained to the group representatives the next task. They had to print the pie charts, bar charts and the tables and create a chart.

PHYSICS LESSON

In part fulfillment of the course work required by the physics SEC syllabus, a lesson in conjunction with Green Week was carried out with a group of form 4 students.

The lesson started off with a discussion about the different forms of energy – renewable and non-renewable, where the students were brought to the understanding of the importance of concentrating the world’s efforts on developing renewable energy technologies based on two basic facts: Non-renewable sources are polluting and are fast running out.

The two major renewable energy sources discussed were solar energy and wind energy due to their relevance to the national scene.  Solar energy was discussed with reference to solar panels and PV cells for the generation of electricity.  The students were also made aware of the fact that PV cells would soon be installed on the school’s roof and they were quite excited about the idea.  One point of interest, is that one student suggested that the government should rent out the roof space of private residences for the installation of PV cells since, due to lack of space, large land area cannot be devoted to this purpose.  The energy changes involved in the use of solar panels and PV cells were explained, as well as the advantages and disadvantages of their use.

Wind energy was also discussed as another viable resource for Malta.  The possibility of setting up an off-shore wind farm and its ideal location were discussed, together with energy changes and advantages and disadvantages.  The model of a wind turbine was shown to the students and its parts were thus made clear.  The wind turbine’s generator was connected to a light bulb and they could thus see how rotating the blades of the turbine made the bulb light.

Other renewable energy sources discussed were hydroelectric energy and biomass energy, where all students agreed that the latter would be an excellent option for Malta due to our small size and the problem of dumping waste.

The Students’ Council was given information  about the Project. The members were then accompanied to the school roof where they were shown the location where the photovoltaic panels were being installed.
