Science on Stage Europe The European platform for science teachers


Materials for outdoor classes

If the weather is nice, it is a good idea to have class outside. We provide you here with an overview of materials that are particularly suitable for this! All publications shown here can be downloaded for free. 

Football in Science Teaching: 

Let’s Get Physical – Measurement, Analysis and Improvement of Performance
The teaching unit ‘Let’s Get Physical’ shows how to combine sports, biology, computer sciences (ICT) and mathematics: Students measure and analyse in five different performance tests how regular and intensive training effects their speed, jumping power, strength, movement coordination, agility and endurance. This way they get familiar with the concept ‚performance‘ on different scientific levels. (physical education, physics, biology, mathematics, computer science)

Smartphones in Science Teaching: 

iSky: Smart Measurements of the Heavens:

The teaching unit ‘iSky: Smart Measurements of the Heavens’ inspires students to investigate the stars. Using various apps of their smartphones the students learn how to orientate themselves based on the night sky, how to measure the altitude of the sun or how to calculate the circumference of the earth. (mathematics, geography, astronomy)

Going for a Song: Measuring noise pollution with a smartphone: 

Do birds sing louder in the city, trying to drown the high background noise? With this question students are dealing in the teaching unit ‘Going for a Song’. Using smartphones and free apps they measure the amplitudes and frequencies of birdsongs in the city and in the countryside. This way the students analyse the direct effect of noise pollution on the behaviour of the animals. (biology, physics)

Spot the Physics: Analysing movements, acceleration and free fall by video:

With their smartphones students record various motion sequences during sportive activities like the throwing of a basket ball or the acceleration during a bicycle ride. Later the students analyse the recorded videos to determine which physical theories can describe the phenomena observed. (physics)

ICT in Science Teaching:

Length of a Day: Altitude of the sun, ecliptic & rotation of the earth:

In this teaching unit students measure or calculate the time of sunrise and sunset on a given day as well as the length of that day, and design the graphical representation of the heights of the sun on the horizon throughout the day. Students can also keep tabs with the data obtained for one day, then repeat the calculations for another day and compare the two. (astronomy, mathematics, physics) 

A look back on our virtual events

Social distancing and school closures also affected Science on Stage. As the largest network of STEM teachers in Europe, we bring together educators with innovative teaching ideas. We support them in their professional development through events like workshops and our festivals.

However, while these events have been cancelled in the past months, teachers had an urgent need for exchange and support regarding the special circumstances they found themselves in. Therefore, one thing became clear to us: we had to expand our digital offer.

The first step was to compile a selection of our teaching materials especially suited for home schooling and we were happy to see that this was well received.

To continue our support for teachers’ professional development, even in times without in-person events, we decided to extend our activities with virtual events and webinars.

Here, the speakers present exciting teaching projects, practical tools and new methods. True to the motto “from teachers for teachers”, all speakers are active in Science on Stage, have participated in one of our festivals with a successful STEM project or have been involved in one of our international teacher projects. Of course, the participants could also show their ideas.

The topics of the virtual events ranged from online resources for primary teachers, inquiry based learning online, the fascination of slow motion and time lapse activities for students to a primary teachmeet, where educators from different countries shared their ideas.

The response was very positive, and participants told us repeatedly how happy they were to be able to exchange ideas with like-minded colleagues. Encouraged by the success of the events, we will organise more virtual events after the summer holidays. The aim is to establish them as a more permanent part of our activities to reach and support more STEM teachers all over Europe.

We at Science on Stage are proud that we were able to adapt to the situation on short notice and could continue to support our teacher community. We could not have achieved this without the active support of our network. We would like to take this opportunity to express our sincere gratitude. We look forward to further events - whether offline or online!



Webinar for Georgian science teachers

In times of social distancing, teachers do not have to abstain from international cooperation and further training. This is also proven by Science on Stage Georgia. On 21.05.2020 they hosted a webinar for Georgian science teachers. It was organized in cooperation with the Science Education Research Centre SALiS, the Copernicus Science Centre and the School with Class Foundation from Poland. 

Science on Stage Georgia Steering Committee member and biology teacher, Dr. Natia Bagatrishvili, held the event, whose topic was "Students inquiry during distance teaching". More than 30 science teachers from all over Georgia attended the webinar. 

Assignment for primary school children: Growing crystals

Primary school children are particularly curious and there are many exciting things to discover, especially in the house. For example in the bathroom: Why are there sometimes white spots on the mirror? Hasn't it just been cleaned? 
We have prepared an assignment from our teaching material "Lilus House - Language Skills through Experiments" in which children get to the bottom of this phenomenon. With just a few household objects they grow crystals and at the same time learn that there is more in the water than they can see. 

The assignment

Lilu, Alina and the spider are at home, but they are not bored. Now they can go on a discovery tour of scientific phenomena! And they quickly find something interesting in the bathroom. The spider notices it first: "Look at the mirror! We just cleaned it, but now there are all these little white spots. But why? Where do all these stains come from?"

Alina replies: "It is lime. It comes from the water we used to clean the mirror." "But the water was clean. I didn't see any lime in it", the spider says confusedly. "There are many minerals in the water, even if you can't see them. Come on, I'll show you with an experiment," exclaims Lilu.


  • cup of hot water
  • clean jar
  • salt
  • spoon
  • coffee filter
  • funnel
  • cord
  • pencil
  • paper clip
  • food colouring (optional)


  • Take a cup of hot water.
  • Add one teaspoon of salt and stir.
  • Keep adding salt and stirring until the salt stops dissolving.
  • Place the coffee filter in the funnel.
  • Pour the saltwater through the coffee filter into the clean jar.
  • Add food colouring if you want your crystals coloured and stir.
  • Tie a paper clip to the cord.
  • Tie the cord to the pencil, so the paper clip hangs in the water while the pencil balances on the top of the jar.
  • Wait to see what happens.
  • Make a drawing of the final result!

Safety! Be careful with the hot water!

Lilu takes a glass of water: "Look, I put a spoonful of salt in the water. After I stir it, you can’t see the salt anymore. That's because the salt has dissolved in the water. But when the water evaporates, the salt crystallises." The spider asks, "What happens now?" "Now we must wait." Lilu attaches a paper clip to a piece of string and ties the string to a stick. Every morning, the spider goes down from its web to find out if you can finally see crystals in the glass with the string.

One morning Lilu and Alina wake up because the spider crawls around on their faces: "You scared me! What are you doing?" shouts Lilu.  "Now you can finally see something: It looks as if there are lots of little white stones on the string and on the paper clip. It seems as if the salt wants to climb out of the glass. Come and see!" Together, the friends look at the crystals they have grown. Now even the spider understands the white spots on the mirror. The lime cannot be seen with the naked eye, but it is there. If you clean the mirror with water, the water will evaporate and the lime will stay behind!
