Snowflake Crystals

This activity shadows the eTwinning Project entitled “Adventures of Atmosphere” which was founded with the teachers from Turkey and Italy including Sakine Rüzgar, Enise Ulu Çoğalan, Yıldız Kanlıöz and Eleonora Burnete.

The aim of the project is to engage our students with understanding the atmostpheric events such as snow, rain, hailing, wind or tornado with this STEM challenge.

Age of students: 9-12.

Time: 30’+30’+30’+20

Activity date : Between 12th-16th of April ,2021


Teachers will conduct preliminary investigations in order to help the students in terms of gaining knowledge on cloud formation, snowflake crystals and the role of clouds in the growth of snowflake crystals. Additionally, they will also help them how to explore TRMM images and data; and the role clouds play in the Earth’s radiant budget and climate.

What is Snowflake ?

When people say snowflake, they often mean snow crystal. The latter is a single crystal of ice, within which the water molecules are all lined up in a precise hexagonal array. Snow crystals display that characteristic six-fold symmetry


  1. Being creative to solve a problem,
  2. Knowing how to clearly express their thoughts in an organized way,
  3. Learning how a snowflake grow up in the clouds,
  4. Giving students the opportunity to learn about the fact via snowflakes simulation and hands-on learning
  5. Developing science skills like observation, classification, measurement
  6. Improving foreign language skills.

Polar glaciers are losing space, and land glaciers continue to melt around the world. This event shows that ecosystem change is starting to accelerate.

Although our world has been exposed to climate changes due to natural causes in the past, since the beginning of the industrial revolution, human beings increasingly continue to release CO2 and other greenhouse gases into the atmosphere by using fossil fuels.

Therefore humankind urgently needs to review this and similar patterns of behaviour that increase climate change and threaten our Earth. Climate scientists acknowledge that it is not possible to stop or reverse climate change, but it is argued that reducing emissions of greenhouse gases can overcome global warming.

Mirrors and Kaleidoscope

Author: Edina Dorovic

Preschoolers from Subotica, Serbia are taking part in eTwinning projects for already a couple of years. Our Preschool Institution “Naša radost” is encouraging teachers to take part in STEM projects, and we are enjoying these little science adventures a lot.


The group called “Ladybugs” (from the kindergarten “Šumica”) teamed up with two other groups from the same kindergarten, and some international partners: Hungary (two classes) and Romania (one class). Our journey with science, physics and optics started in March 2020 with an eTwinning project “Tükröm, tükröm…” (“Mirro, mirror”). We used fairy tales and stories about mirrors to evoke interest in STEM subjects in our preschoolers. We used cameras, mobile phones to capture reflective images in our classroom, yard, street etc.

The project “Tükröm, tükröm…” (“Mirro, mirror”) was prepared for the Digital Theme Week (held in Hungary) held on 23 – 27 March 2020.

Our goal was to introduce children to the world of science by working on digital competencies. We used a lot of web tools: Metaverse, Musiclab, Permadi.
