3D - PRINTER
A particular challenge was launching the 3D printer. After very careful study and assembly, the 10th grade students created models based on products programmed by them. We presented some of these products at a charity bazaar to raise money in favour of a colleague in need.
The students’ environmental education was provoked by the hydrogen car model, which is a part of the equipment received. Due to the strong interest of the students, we contacted the Bulgarian Federation of Motor Sports. A team was created and with the donated model of a sports hydrogen car we participated in the National Competition, where we won silver medals. The preparation of the new student team for the competition in June this year is currently underway.
LESSONS - NATURAL SCIENCES
The teachers Milena Yordanova and Svetlana Brankova are actively working to increase interest in the natural sciences. They work in a team in classes with students aged 10-14.
1. Compact Photometer for drinking water PF-3 in combination with proven powder pads or tests. It allows a quick and easy way to monitor and check the most important parameters for drinking water (chlorine, chlorine dioxide, pH, fluorine and iron) for all water suppliers and industrial consumers during drinking water treatment.
2. Little Bits, projects with different applications in science. For example, the Balloon Generator, which can be used to create balloons from a chemical mixture formed as a result of a chemical reaction, and the Lightboard, an invention for detecting sound waves. It can be used to detect different types of sounds and their frequency.
3. Electrolysis - an oxidation-reduction process that takes place under the action of an electric current in a melting vessel or electrolyte solutions. Electrolytes are substances whose melted or aqueous solutions can conduct electricity as they dissociate ions.
4. Hydrogen Prototype Car. It is connected to a reversible fuel cell that acts as an electrolytic cell and a single transformer to drive the car. This is done by removing hydrogen from purified or distilled water (pH> 5.5) and then converting it into energy that drives the vehicle for a certain period of time, depending on the pH value.
5. Racing Hydrogen Car. Our team assembled the chassis of the car itself, designed a coupe for it and went through a series of drills to optimize the hydrogen used through the fuel cell.
After all the tests the competition day came We were 4 teams from different regions of Bulgaria for the Horizon Grand Prix, the competition, powered by hydrogen gas, in an attempt to raise awareness of teenagers to an alternative to fossil fuels. The venue was a basketball court adjacent to a science pavilion. It was a grueling four-hour radio-controlled model race with numerous stops, car crashes and happy parents. The aim of the competition was to complete as many laps of the complex competition course as possible within four hours. We finished second, but that didn’t stop us from enjoying ourselves.
PROGRAMMING AND ITS APPLICATION
During the COVID pandemic, our student Boyan Apostolov found a solution to one of the problems -quick access to medical care. He created an online platform for quick access to specialized medical care. This platform enables users to quickly find and connect with the required medical professional from all over the country.
RELATIONS WITH INSTITUTIONS
The main partner in our work in natural sciences are the specialists from the Regional Inspectorate for Environment and Water/ RIEW/. Our students visit their laboratories with interest and get acquainted with the responsible attitude towards nature. The specialists from RIEW - Veliko Tarnovo are favorite guests in our lessons.
Our work in all areas of MAST workshops is a good practice, which we proudly shared with partners from Jaipur, India. During their first visit to us, we showed them the equipment and the opportunities it provides. The Indian colleagues were also guests in our classes.
