European Researchers’ Night offers science and action in Joensuu

On 27 September, the European Researchers’ Night will once again take over the Joensuu Campus, welcoming people of all ages to enjoy science. Our workshops, stands and booths will be open in the Aurora building at 16–20. The European Researchers’ Night will be hosted by Radio News Reporter Liina Mustonen.


Are you interested in climate and health effects of residential wood combustion? Meet us in the research sauna.
Finnish people enjoy the small moments in front of the fire and in the heat of wood fired sauna. In Finland, residential wood combustion is the most important source of fine particles. In addition, black carbon particles emitted from stoves and heaters in northern Europe are especially harmful in terms of climate warming. In wood combustion simulator, different types of wood combustion appliances are being developed. What is the best wood specie? How does the moisture content of wood affect? Are there differences in sauna stoves? Answers e.g. for these questions are found in the wood combustion simulator!


Biobank of Eastern Finland
A biobank collects biological human-related samples along with their associated information based on the donor’s consent, and provides access to them for biobank research. How samples and data are processed in a biobank? How can a biobank sample contribute to the future medicine and healthcare? Come and test your knowledge of biobanks! You will also see tissue samples scanned in a digital microscopy.

Do you have a tree-friend?
Dive into the world of special trees! Do you have flowers or cones in your tree? Is it fun to climb? Can you hug your tree-friend? In the workshop, children will be researchers interviewing the adults about their favorite trees. In a workshop, research is done through discussion, questioning, drawing and reflection - just like real research.The workshop is organized by the Trees Near Us - research project.

Meet and Greet Digi-Erics: Tutoring of Drones, VR and Green Screen
There are digi tutors, student agents and then there are the Digi-Erics from the 6th grade. The Digi-Erics give peer support in technological matters by tutoring and helping others. Come and join them in the workshop of VR, drones and Green Screen.

Epic Rover Challenge
Your team is on Mars. Your mission is to retrieve an item that was dropped in an uncharted area. Be as fast as you can! The team must stay in the Mars base, but you can use an RC-car, tablet computer, action camera, tape and other crafting materials to execute the mission. The fastest team will be awarded!

Food in the municipality of my dreams
Food & Municipality – project’s workshop you have a possibility to envision, what is a municipality like, where the food related services are realized equally? What kind of actions would do the food educators of your dreams? What is a mealtime like in the day care center of your dreams?

Come and find the lost mitten!
Where do you come from? Where are you heading to? What do you carry with yourself? Come and take a chance – find the lost mitten with the project Lost mitten and other stories!

Stormy letters
Solve the problem of the old fashion letters. Write your own name in fraktur style and decorate fancy letters yourself.

Create your optimal learning environment
UEF’s goal is to have the best learning environment in Finland. The learning environment can mean many things to people as well as at different levels. As a leading teacher education training university the learning environment extends to the schools as well as the environment for which students at higher education attend. Innovative teaching methods, evidence-based practices with physical and virtual structures can make a learning environment the optimal one. In this researchers’ night, we offer hand’s on workshop on individuals creating their own optimal learning environment. We encourage fellow researchers, students and the general public to visit us to investigate ways in which they believe to be the optimal learning environment. There is the opportunity to convert basic ideas into concrete structures through moving props, designing animated stories and virtual learning environments. Demonstrations of the Digicampus and MOOC courses will be shown during the workshop and people have opportunities to look at registering and how to take advance of these courses.

A little bit of science
Welcome to test your skills in a playful spider-game. The game requires cleverness and a good blowing technique. Additionally, the workshop offers you many other funny tasks for challenging your problem-solving skills.

Does sandpaper affect on taste? - workshop on how senses work
Have you ever wondered how a piece of sandpaper (not in your mouth) affects the mouthfeel of a drink or food? What about a soft piece of cloth? How about rubbing your top of the head with a fork? At this workshop it is possible to try how seemingly irrelevant things affect the perception of taste and mouthfeel. Participants also have a possibility to participate in a real experiment if they choose so.

Carbon footprint: What can I do to mitigate climate change?
Individuals play a key role in helping to mitigate cliamte change. In this pit-stop you will find out whether you know which personal actions are the best ways to help combat climate change.

Mathematical art
Come see a harmonograph - a device that draws mathematical art by itself!

Finnish Civil War 1918
The Historical Association of North Karelia (PKHY) takes us back to Joensuu a century ago. Come investigate the history of the Finnish Civil War in 1918, its memory in Finnish historiography, and the dark histories surrounding us in our cityscape today. We discuss how and where the Civil War should be remembered – or is it about time to forget and to move on?
On a lighter note, come to uncover the global history of Karelia. People connect us in time and space. So, who should we remember and why? The Historical Association of North Karelia will produce amazing paper dolls based on your answers.

Random sample and reality
Research is often based on quantitative data, which is used to answer questions about reality. The data includes noise, and the essential task is to separate the essential information from the noise. Often the statistical analyses are based on hypothesis testing using magical limits of 0.05 and 0.01 for the probability to reject a true null hypothesis.  We face with similar issues about randomness also in our everyday life. For example, there are numerous gallups prior to political elections that try to estimate the true popularity of different parties. Our cellphones may recognize us by face or fingerprint.
In this non-stop workshop we learn about randomness by doing. We use touchable tools for that purpose: an urn filled by wooden balls of different colors, and specially made dice, which have unknown probabilities for different spot counts.
The questions include:
•    Estimation of the probabilities of the dice spot counts,
•    Exploring how rare is an event that happens with probability 0.01 or 0.05,
•    Estimating the proportions of balls of different colours in the urn
•    Simulating the lifetime of a human
•    Guessing the dice your friend used based on a series of dice plays.
