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.
Biodiversity is under threat. Can an app that recognises different species of ladybirds help provide a solution? Pupils and members of the public from across Sweden are being invited to get involved in real research to find out in a mass experiment being run as part of the 2018 Researchers’ Night in Sweden. The Ladybird Experiment is joint initiative between the Swedish Museum of Natural History and the civil society organisation VA (Public & Science).

How credible do teenagers think the news in their digital news feeds is? And where do they get their news from? Around 6,000 pupils have been helping researchers to investigate these questions in a citizen science project involving schools across the whole of Sweden.
In 2015, Swedish school pupils helped scientists to bury over three thousand tea bags in the countryside. The Tea Bag Experiment is a mass experiment to investigate soil decomposition rates in different parts of the country and how the process is being affected by climate change. The results have now been published and show that the first phase of decomposition is particularly affected by a warmer climate.

Swedish children and teenagers are pretty diligent at eating fruit and vegetables, according to the results of a mass experiment organised as part of Researchers’ Night. In the Vegetable Experiment, scientists at the Swedish National Food Agency enlisted the help of over 5500 pupils, who acted as research assistants for a day. Carrots and apples top the list of most eaten vegetables and fruit.

Is it possible to read the future in tea leaves? This is what scientists at Umeå University are hoping to find out and they are now looking for school classes across Sweden to participate in a mass experiment that will help to inform climate change research. The so-called ‘Tea Bag Experiment’ is part of the European science festival, Researchers’ Night.

Spring is now here and it arrives earlier each year. A warmer climate means an earlier spring and a later autumn. But how is the delayed onset of autumn affecting the Swedish ecosystem? A mass experiment involving over 10,000 pupils across Sweden is helping scientists to study the effect of climate change on deciduous trees in autumn. Läs mer
