STEM Discovery Week – Kyustendil – Bulgaria

The Open House Day in High School of Maths and Science „Prof. Emanuil Ivanov” Kyustendil, takes the form of workshops, demonstrations, quizzes and interesting events. Students and teachers in different fields demonstrate to future students, from different schools in our city, how interesting and useful is to deal with STEM science.

The tagline for this year’s campaign is “best practices in using innovative STEM resources”. The primary focus of this year’s campaign is to showcase how educational materials and other learning resources are used in educational activities.

We will tell you how teachers with their knowledge and experience, with the help of prominent students, make the educational process much more interesting and related to real life.

Biology

Demonstration of experimental behavior of plant and animal cells in osmosis.

The experiment introduces to students facts known to science and used to reproduce in a laboratory the processes or phenomena that can not be observed directly in nature. It is also due to the fact that much of the information is abstract and unknown. The experimental settings are simplified and, in the shortest time, lead to the revelation of the essence of the studied processes. As a method, it builds valuable attributes such as observability, wits, tenacity, responsibility and teamwork skills, encouraging their cognitive and creative activities. So the idea of ​​using the osmotic behavior of plant and animal cells on the Open House Day to raise the interest of high school students to science, and more specifically to biology, has arisen.

Using experimental methods, students introduce and define one of the type of transport in animal and plant cells and experimentally demonstrate the process of osmosis in plant and animal cells.

Chemistry

– presentation of spectacular and entertaining chemical experiments – chemical volcano, elephant paste, rinsing gas, burning of magnesium, ignition of match-free spirit lamp

– study of the medium (pH) of different solutions

– scientific workshop – handmade soaps, blue stone crystals, chemical clocks, chemical calendars, luminous periodic table and more.

– marking the 150th anniversary of the creation of the periodic table after announcing the 2019th for  the year of Mendelian Table by UNESCO

Computer Sciences

We performed a presentation for the device micro: bit – idea and programming. We also showed tasks with programs – a throbbing heart and a temperature sensor. The students tried to program on their own visually with Scratch and Micro:bit platform. We showed the football mission of the LEGO robot, represented by the school robotics team, and we painted geometric shapes with Finch robots.

We used the resource from the Scientix repository http://moodle.scientix.eu/course/view.php?id=198

Mathematics

Mathematics teachers organized a race to solve funny tasks, with all groups of visitors divided into two teams competing for the grand prize – “treasure”.

Each team had to solve three logical tasks. The answer to each assignment, through certain instructions, led to finding the next task hidden somewhere in the room, respectively, to the treasure, the material expression of which was a candy.

Students involved willingly in the game. It was funny and interesting for them.

Arts

We have demonstrated various ways of painting, with the most attractive was encaustic or painting with an iron. Exhibition of ready-made drawings and photographs was shown.

Physics and Astronomy

“Matter and Energy”

A discussion and demonstrations were held in front of our guests by a team of students of the High School of Math and Science “Prof. Em. Ivanov “, participating in Olympiads and competitions in physics and astronomy. The themes were:

“Astronomical phenomena” – talk, “Eclipses and phases of the moon. Difference in the synodic and sideric period of the moon and explanation. Solar System and Planetary Configurations. “,” The Miracle Fire Bubble “- an experiment (heating two bubbles, why does one of them burst and the other does not? In fact, the whole secret is in the water placed in one of the balloons)

“Geometric optics experiments” :

• Straight light spread.

• Reflection and refraction of light.

• Full internal reflection of light.

• The principle of human eye action, its disadvantages and their correction.

• The Principle of operation of optical instruments.

“Hologram Demonstrations” (kindly provided by colleagues from the Department of Natural Sciences) – lecture and experiment, explaining the recording of a hologram with lasers and reproduction of its image.

The goal was for students to understand that light is a kind of energy. There were a lot of questions and students from all groups received awards – star and moon maps and solar watches made by the team.
