Sweety STEAM Project – Chocolate Challenge

This activity is part of the Etwinning Project “Sweety STEAM”. The Project is carried out in partnership of 13 teachers from different countries. Throughout the project, we carried out monthly activities. The February activity is mainly organised for the STEM Discovery Challenge using the Scientix Repository Resource “The Chocolate Challenge. Quantitative sensory evaluation of food”. Here, in this blog, we want to tell about our project “Sweety STEAM”, and also the resource we selected from Scientix Resource Repository.

Abstract: At the beginning of this project students read a fantasy novel, Charlie and the Chocolate Factory, which is one of the best selling childrens’ books. Following the reading activity, students fulfilled a series of STE(A)M challenges integrated with literature because we wanted to arouse the curiosity of children and to create an opportunity to develop students interest in STE(A)M education.

Project Activities

First Month Activities

First, children read the novel Charlie and the Chocolate Factory. Secondly, we applied the Book Review Kit at the British Council Public Website. Students did listening and matching activity under the preparation part in the page and then applied the Worksheet for the writing activity.

Lastly, students did a reading and drawing activity. They depicted what happened in the novel or a particular scene. We used the best student drawings from each partner and we created a common art magazine. Click on the link below to see our collaborative work.

Art Magazine

Second Month Activities

At the beginning of the activity we asked the students: Would you like to open your own chocolate factory like Willy Wonka? Following that, the students learned how to make chocolate. During this activity, the students experienced solid-melt-solid.

Further, we carried out a student discussion using some questions. For instance:

Question 1

Discuss what temperature does chocolate melt at? (Answers received: average 32-34 degrees C, a little bit lower than your body temperature, that’s why it can melt in your mouth)

What factors cause a chocolate melt or become solid? 

Question 2

Tasting chocolate – How does chocolate taste? 

Students gave answers and talked about 4 basic tastes (sweet, sour, salty, bitter). After that, students explored the tongue map, so they learned how different parts of the tongue have different sensory receptors for different tastes.

Question 3

Discuss if melting and freezing a physical or chemical change.

Afterwards, students examined the graphic below and answered: ‘What can be interpreted from the data?’

Students used twinspace forums, so that they could note down their answers. In this way, they could see each others’ answers. Web 2.0 tools, such as Padlet, can be used for the same purpose.

Finally, we joined the STEM Discovery Campaign Challenge. Thanks to the Scientix Resource Repository, we found and selected an enjoyable resource that matches our project theme, titled “Chocolate Challenge”. Here is the link for this resource: Chocolate Challenge

As a result, we could manage to complete a series of activities in an interdisciplinary way around the same theme. Moreover, we had the opportunity to embed Scientix in Etwinning Projects. It was a great experience for all partners because ‘STEAM has never been so sweet!’

Online workshop Brain Lab Challenge of the future

Author: Madlen Christova, 125 Boyan Penev Secondary School


Start date 4/5/2021

End date 4/27/2021

Beneficiaries: students in 7th grade

Activity: The online workshop “Brain Lab” includes preparation and presentation of mind maps on the challenge “What if…” based on topics in mathematics, science and technology. The students work in teams. The mind maps contain hypotheses, forecasts, research of available and necessary resources, interviews (studies) among peers, parents and STEM professionals.

Procedure: The session is realized within the subject “Project Design” in 7th grade. Each team decides the format and the way of presentation: multimedia product; etude; real model. The session ends with a general discussion.

Topics: “What if there is no gravity?”; “What if there are two Suns in our system?”; “What if we all live in an aquatic environment?”; What if there are no numbers? What if we can change the colour of our skin? “If the buildings could move.”

What if there is no gravity?

Improve Students’ Competence With STEM Challenges Related To SDGs

Author: Zeynep Ceren ÇİFTSÜREN

I work in a rural school where students come from immigrant families. The parents’ economic level is usually very low. The majority of my students don’t have technological tools (computers, laptops,etc.) at home. Even though most of my students’ families have smartphones, they do not have a proper Internet connection.

Now consider my mood! I was really shocked when I first heard that schools were closing. How would I reach my students? Of course, I had my students’ phone numbers and a WhatsApp group. But this was not enough for online teaching.

So what am I going to do in this process? Of course, we can work on SDGs! Our school was involved in the Sustainable Development Goals Project and Climate Action Project. My students had a certain level of knowledge about global issues.

So I decided to prepare STEM Challenges related to SDGs for them. I used Google Slides for these events. This Google Slides tool is interactive and there is a possibility to upload videos too. At the same time, I prepared the infographics of all STEM Challenges. I shared Google Slides named Improve Students’ Competence With STEM Challenges Related To SDGs” and infographics via WhatsApp group, uploaded them on Google Drive, via email and posted them on the school website. Our activities were held on 20 – 30 April 2020.

Participants: Etwinning Project Partners Teachers, Students and Parents from

As partners of the eTwinning project from Stem Club to Stem School, we decided to participate in Stem Discovery Campaign with a challenge, led by project founders Candan Kilbul and Cem Moran. We talked about what we could do for the 2020 STEM Discovery Campaign and how we could apply online teaching by organising webinars.

Our schools have been closed since 13 March 2020 because of the Covid-19. For this reason, we decided to do a challenge called “Stay Home With STEM” by doing STEM activities at home. We made a lesson plan under the leadership of our project founders.

We implemented various live events and sound recordings with our students in our lesson plan. The students were given a task related to our daily life. They were asked to think about how we could help the elderly uncle in the fairy tale (that we read) to measure things. The students made an interesting investigation on the Internet and shared their finding related to the weighing tools. They designed how they could scale various things.
