Press release for students - Hair ice mystery solved

EGU Planet Press

From EGU, 07/22/2015  --  Did you know that there is a type of ice called hair ice? It is shaped like fine, silky hairs and looks like white candy floss. It grows on the rotten branches of broad-leaf trees during humid winter nights when the air temperature drops slightly below 0°C. A 100-year old theory states that hair ice also needs something else to grow – a fungus – but, until now, no one had managed to confirm this.

Planet Press is an initiative from the European Geosciences Union (EGU) aimed at getting kids (mainly 7-11 year olds), parents, and educators interested in and engaged with up to date scientific research and news. Each Planet Press is reviewed by a scientist and educator to ensure the content is scientifically accurate and that the language used is appropriate for the 7-11 age range.  If you are an educator, these press releases can be used in the classroom to aid teaching about current subjects such as climate change or earthquakes and tsunamis, to make lessons more interesting and relevant by taking into account modern science and developments.  To see previous Planet Press articles, visit: http://www.egu.eu/education/planet-press/articles/.
