2nd and 3rd of may, the Kinderuni took place in Radstadt, providing opportunities for kids to get in touch with scientific work. The iDEAS:lab offered a workshop about observations of weather phenomena, which the pupils could explore hands-on using the sensebox:edu. In small groups they built up weather measuring stations, explored sensors and measurement methods and drew comparisons of different light sources: How strong is the luminous intensity in part of the room illuminated by the sun versus in the shadow? How hot is a classical lightbulb in comparison to a LED light? The kids were eager to try out the different settings, seek extreme values - and even spontaneously recorded their results for comparisons.
