Interstellar visitor

According to a report in Science Daily:
"A small, recently discovered asteroid -- or perhaps a comet -- appears to have originated from outside the solar system, coming from somewhere else in our galaxy. If so, it would be the first "interstellar object" to be observed and confirmed by astronomers"

A big solar flare

According to a report in Scientific American there has been a big solar flare - the biggest in 12 years.
"The Sun's level of activity goes up and down in an 11-year cycle: sometimes it produces a ton of large flares, and sometimes it's pretty quiet. Every solar cycle, the Sun delivers a few standout punches. This current solar cycle, however, is the quietest in the last 100 years. It's pretty notable that such a large flare came out of such a calm period."

Questions for discussion: what is a solar flare? Why are they important to us?

Science CSEC results for Guyana

According to a GINA report the results in Chemistry showed improvement.

However:
"The eleven subject areas where Guyana’s “performance did not measure up when compared with last year’s performance were: Biology, English A, English B, ... Integrated Science, Physics, ... Human & Social Biology, and Additional Mathematics."
With regard to these subjects the Minister said:
'“We therefore recognise that these performances indicate that appropriate measures have to be taken to ensure overall improved performance in all subject areas,” the Minister of Education stated.'
Performance in Mathematics was said to be "consistent".

STEM team returns to Guyana

Image from Guyana Chronicle
According to a report in the Guyana Chronicle:
The young Guyanese team...placed 10th after battling against 164 other countries from around the globe. The achievement by the nine-member team is phenomenal, considering that they had only four months to prepare for a competition which was new to them. However, their achievement is being celebrated by the Guyanese population.
The First Global web site gives some background:
FIRST Global organizes a yearly international robotics challenge to ignite a passion for Science, Technology, Engineering, and Mathematics (STEM) among the more than two billion youths across the world. 
but has little regarding the outcomes of the event.

STEM Guyana

This initiative is introducing young people here in Guyana to the basics of robotics. According to an article in the Guyana Chronicle:
First Lady, Mrs. Sandra Granger, today, met with the group of young Guyanese ... who are currently fine-tuning their robotic project in preparation for the inaugural Robot Olympics in Washington DC, USA in July.
More than 150 countries from around the world are expected to participate at the Robot Olympics. This initiative is part of the wider Science, Technology, Engineering and Mathematics (STEM) programme, which was started last year under the aegis of the First Lady’s Office. It is being spearheaded by Ms. Karen Abrams, an overseas-based Guyanese.

An exhibition is planned for June 24th.
