Refugee children explore cosmos with Universe Awareness
14 October 2016
In September 2016, the educational programme Universe Awareness (UNAWE) implemented a series of educational activities at Basisschool De Verrekijker, a primary school for refugee children in Katwijk, the Netherlands.
In this month-long astronomy project, more than 180 children and their teachers engaged in astronomy educational activities. For instance, participants learned about the planets of our Solar System and created their own spaceships. This astronomy-themed month was concluded on 30 September with a visit from the NOVA Mobile Planetarium and a family day where parents and siblings could see what the students learned and created.
Since early 2016, UNAWE has implemented several initiatives with refugee children in the Leiden region. UNAWE aims to inspire young children around the world with astronomy, science and technology, because astronomy embodies a unique combination of scientific and cultural aspects. Learning about our amazing cosmos offers a special perspective on our place in the Universe that encourages a sense of global citizenship and tolerance.
In the first half of 2016, UNAWE implemented Discovery Club, an after-school Science, Technology, Engineering, Arts and Mathematics (STEAM) programme developed to inspire, educate and entertain children and parents in refugee centres. Discovery Club held weekly sessions with a group of around 30 children. According to Tibisay Sankatsing Nava, Project Manager at UNAWE, there was an enormous willingness to help by volunteers within, as well as outside the Sterrewacht: ‘With the volunteers we managed to provide fun, hands-on science activities for the kids every Saturday. The children needed continuity: their lives had been disrupted and the weekly activities provided both a fun learning opportunity and stability while they were in the emergency center.’
This video is called Singing male common rosefinch (Carpodacus erythrinus).
The male bird sang, sitting in a tree. Probably, he rested there for a while during his spring migration.
The rosefinch attracted quite some birders with telescopes and cameras.
Most probably, the young whale died because of a collision with a ship; some of its vertebrae were crushed. Other possible causes of death: a killer whale attack; or a collision with a seawall.
