Every autumn since 2009, thousands of Swedish pupils of all ages have been helping researchers gather huge amounts of data. These so-called mass experiments are of mutual benefit: the researchers get more data than they could otherwise easily collect, the pupils get the opportunity to participate in real research, and the teachers get material and methods based upon state-of-the-art research to integrate in the curriculum.

VA (Public & Science) coordinates the mass experiments as part of the European science festival, European Researchers’ Night.  Schools from across the whole of Sweden are involved.

The mass experiments efficiently link education to research, establishing valuable contacts with researchers and giving students insights into research methods and scientific thinking.

VA helps the researcher to design an experiment whereby students gather data guided by their teacher. Research projects are also selected according to how well they fit into the curriculum. Instructions and teachers’ manuals are jointly developed by the researcher and VA, and researchers also communicate directly with individual teachers and students using Twitter, Facebook and Instagram.

We have been running mass experiments since 2009. Here you can find an information folder about the Swedish mass experiments.

Examples of our most recent experiments:

The Food Waste Experiment of 2020 investigates whether more information can result in less food being wasted. Here, pupils will be using an artificial intelligence app and the world’s largest food sustainability database.

VA’s annual mass experiments are examples of citizen science. Our experiences from conducting them are shared in an essay published in the Journal of Science Communication that discusses how mass experiments/citizen science can stimulate scientific literacy and an interest in science while generating scientific output.

Other citizen science-related projects

VA is currently part of a collaboration project aiming to create a national portal for citizen science in Sweden, which started in January 2018. More information about the project, ARCS, can be found here.

VA is also a partner in an EU-funded project called EU-Citizen.Science that will develop a European platform for citizen science, together with 13 other European organisations. The three-year project started in February 2019.

VA is also a member of ECSA (European Citizen Science Association).

Finding the Vasa cannons is an international project, in which members of the public will be invited to join the search to find out what happened to the cannons of the Vasa, a 17th century Swedish warship.

Young people in Sweden, Spain, Ireland and the UK help researchers to successfully test new method for measuring light pollution

In 2019 and early 2020, school pupils, teachers, scout groups, astronomers and interested members of the public in Sweden, Spain, the UK and Ireland went out to count stars in the night sky. The objective was to help researchers to test a new method for measuring light pollution. Researchers have analysed the results and these have now been published.

Swedish pupils to participate in research to reduce food waste

Press release 4 June 2020

Can more information result in less food being wasted? Researchers will be investigating this together with pupils and teachers across the whole of Sweden in the ’Food Waste Experiment’. To assist them, they will be using an artificial intelligence app and the world’s largest food sustainability database.

Swedish Star-Spotting Experiment off to a sparkling start

The Star-Spotting Experiment, this year’s citizen science project in connection with the European Researchers’ Night events in Sweden, is now well underway. Members of the public across Sweden are helping scientists to measure light pollution by counting stars in the sky and recording the data in a specially-designed app. Here we catch up with Lena Söderström, Project Manager at VA (Public & Science), who is coordinating the Star-Spotting Experiment, to find out how the project is progressing.

Mass star-spotting experiment to investigate light pollution in Sweden

Street lamps, illuminated signs and buildings – lights at night improve safety and make cities more attractive, but have also been shown to have negative effects for humans and animals. The more light there is, the fewer stars you can see in the night sky. In this year’s mass experiment, more than 11,000 pupils, families and other members of the public will help scientists measure light pollution by counting stars in the sky.

Swedish teenagers participate in experiment to assess credibility of election news

Around 2,500 teenagers from across Sweden have been helping researchers investigate the credibility of political news in the run up to the Swedish election. The News Evaluator Election Special was an experiment designed to find out more about where Swedish teenagers get their digital news on election issues from and how reliable they perceive the news to be.

ECSA 2018 – post-conference reflections on citizen science

The second international conference of the European Citizen Science Association (ECSA) was held in Geneva, Switzerland, on 4–5 June 2018. VA’s Fredrik Brounéus and Dick Kasperowski from the University of Gothenburg gained inspiration for their current work building a Swedish national portal for citizen science. And, as often with conferences, they returned home with more questions than answers.
