As a child, how would you have liked moving schools in new cities with different cultures every 2-4 years?

Growing up in the #IndianArmy, I absolutely loved it! By the time I was 18, we had moved over 9 times across 9 states! #Diversity #India #TravelTuesday #IWS #VoicesIWS
My #memories of #India include sunny days, welcoming people, rich heritage, vibrant colors, abundant fruits and mouth-watering street food! #IWS #VoicesIWS

Hello, I am Edna Matta. I was born in #Ibague, known as #Colombia’s #CityofMusic. A beautiful place near snow-covered volcanos (Ruiz, Santa Isabel and Tolima), large expanses of paramo forest, lakes and streams where a diverse array of animal and plant species coexist
My story starts with #powerful, #strong #women in my #family. I was the third of 4 children and my mom #firstMentor had to raise us practically alone, since my father had to work in a different city, 20h away by car
My mom is a very #strong #woman that taught me #values, to #workhard and to be #self-sufficient #StrongWomen #StrongFamily

(1/14) So this is going to be my first true long post to Twitter and I am also covering the debate surrounding the banning of plastic straws. As such, I am rather nervous and I can only hope that this turns out alright! #StrawBan
(2/14) I want to focus on an alternative material used in drinking straws. This material is chitosan, which is also sold under the name of “REPA” amongst others. Chitosan is a biodegradable polymer made from renewable materials used to make flexible straws. #StrawBan
(3/14) Firstly, I shall cover the science. Chitosan is a modified form of chitin. Chitin is taken from renewable sources and deacetylated. This typically occurs through treating it with sodium hydroxide in an aqueous solution. #Chemistry #MaterialsScience

Ok, this story bothered me. Celebrities and the uber-rich should not be buying animals they can't care for, and people should not sell sharks either. It's important to remember that sharks, and most saltwater #aquarium fish, are taken from the ocean...

...unlike most freshwater fish in #aquariums. Because the sharks are captured, they suffer from extreme stress and injury. They'll rarely acclimate to the aquarium. Many of the aquariums shown in the article look awesome but aren't designed to offer the fish a good environment...
... If you wish to have an aquarium, buy farm-raised fish and begin the process with a focus on keeping the animals, and yourself, safe. Don't begin with a tiny aquarium either. Little tanks have more volatile #chemistry and temperature. Start with 30 or 40 gallons. Also...

5 Boron B, named after the mineral borax which the element was first extracted from using electrolysis by British Chemist Humphry Davy who called it boracium. The -on suffix came later by analogy with carbon. #EotE #etymology #Chemistry #Science #Language
6 Carbon C, named from Latin for coal: carbo. Late 18th Century French scientists demonstrated graphite, charcoal & diamond made of same element naming it carbone, 1st listed by Antoine Lavoisier in famous 1789 chemistry textbook. #EotE #etymology #Chemistry #Science #Language
7 Nitrogen N, confusion in 16th C led to natron (sodium carbonate) & saltpeter (potassium nitrate) both being named nitre in French. French chemist Jean-Antoine Chaptal named the new gas nitrogene, -gène, producing from Greek -γενής #EotE #etymology #Chemistry #Science #Language
