Schools : Here's again ! Ready to explore the Geminid meteor shower ?

The biggest meteor shower of the year is set to put on a shooting-star show tonight when the Geminid streak across the sky - at least in places that won’t be overcast. 

The so-called “rock comet” came within 6.4 million miles of earth this past December, although last year’s supermoon made it harder to appreciate the celestial light show. That won’t be a factor this year.




The Geminids will be the last of 2018’s major showers and will enter the Earth’s atmosphere at speeds of up to 70 kilometres per second.
The falling stars are considered different from other meteor showers in being multi-coloured, with white and yellow and a few green, red and blue lights.
The Royal Observatory Greenwich (ROG) says the colours "are partly caused by the presence of traces of metals like sodium and calcium, the same effect that is used to make fireworks colourful”.
People wishing to observe the meteor shower should try to get away from areas with light pollution.

Doodle:

Google celebrates the Geminid meteor shower with a Doodle! And it's adorable!

The slideshow Doodle follows the Geminids’ path through Earth’s atmosphere as it lights up the sky. As Phaethon’s orbit leads it near the sun, the extreme heat causes it to fracture and leaves a trail of debris in its orbital path. 






Every December, Earth’s orbit leads us through the trail of 3200 Phaethon and its debris crashes into our atmosphere at 79,000 miles (127,000 km) per hour. Once through the Earth’s atmosphere, the Geminids’ radiant (or where it appears to originate) is the constellation Gemini—from which the meteor shower gets its name. 

The Geminids are considered to be one of the more spectacular meteor shower during a year, with the possibility of sighting around 120 meteors per hour at its peak.





The Geminids appear every year in mid-December when Earth passed through a stream of debris from "rock comet" 3200 Phaethon. Typically more than 100 meteors per hour stream out of the radiant in the constellation Gemini. when the shower peaks on Dec. 13th and 14th.

Some history:

Named after the ancient Greek god Apollo’s son, 3200 Phaethon is an asteroid whose orbit brings it closer to our sun than Mercury. 

First discovered via satellite data 35 years ago, Phaethon is responsible for bringing the spectacular Geminid meteor showers to Earth’s atmosphere each December. With each passing year since the mid-1800s, the proliferation of yellowish streaks of light in the night-time sky have grown more intense.

The Geminids. It’s a good time to bundle up, go outside and watch one of Mother Nature’s best sky shows!

If the weather is clear, 2018 should be the best year ever to watch the Geminids - so named because they seem to originate from the constellation Gemini. 

Some information for skywatchers:

No need for a telescope or binoculars: fragments from Phaethon’s debris trail should become visible after 9 pm on December 13, peaking after midnight with as many as 120 meteors per hour. T

The cosmic dust may have resulted from a crash with another flying object, but there’s little danger of any Geminids landing on earth as it normally disintegrates in the earth’s atmosphere.

What do Geminid watchers need to do this year?
It’s pretty simple, actually. The nearly First Quarter Moon sets around 10:30 p.m. local time, so wait until then to go out – the light from the Moon washes out the fainter meteors, which are more numerous. 
Find the darkest place you can, and give your eyes about 30 minutes to adapt to the dark. Avoid looking at your cell phone, as it will mess up your night vision. 
Lie flat on your back and look straight up, taking in as much sky as possible. You will soon start to see Geminid meteors. As the night progresses, the Geminid rate will increase, hitting a theoretical maximum of about 100 per hour around 2 a.m.

Education:

Wow! Here's again the spectacular Geminids meteor shower, this 13 December until dawn December 14! The awesome Geminid meteor shower will be back with its awesome show.

The winter, cold temperatures contribute in making this shower neglected by the public, while it offer bright, very enjoyable meteors. 

Most of us are excited about the Geminids shower. Schools, teachers, students and all Skywatchers lovers. 

I'm not a Sciences teachers. I'm Humanities and Arts teacher. But, I love science and all the high technology near science.

The Geminids, along with the August Perseids, are the two most active annual meteor showers. They can always be relied upon to put on a good show, and that is especially true this year, because the moon will be only a few days old, setting early in the evening.

This year the European teachers and students are still at school for a few days, just ending school time before Holiday season.

Using the smartphones, students will need a cable release chord. Luckily they can actually use their iPhone headphones' cable volume button to activate the shutter. And they also need an app designed to take long exposure photos.

Sciences curriculum will be enhanced with this awesome event! The Geminids meteor shower.

Do you want a better science lesson ? 

For optimal viewing conditions, get as far away from city lights as possible, and remember to dress warmly as you enjoy one of the greatest shows on/or above earth.

Schools : Civics & Environment : Climate Change : #TakeYourSeat !






COP24, the two-week 24th conference of the parties of the United Nations Climate Change Convention (UNFCCC), started on Sunday in Katowice, Poland, with a special focus on carbon neutrality and gender equality
On Monday, the grand opening ceremony took place the 3 December with about 40 heads of State and heads of Government in attendance, as well as UN Secretary-General, António Guterres. 


António Guterres, UN General-Secretary
"Our job here in Katowice is to finalize the Paris Agreement Work Programme - the rule book for implementation. I remind all Parties that this is a deadline you set for yourselves,"
António Guterres, UN General-Secretary
Thousands of world leaders, experts, activists, creative thinkers, and private sector and local community representatives will gather to work on a collective action plan to realize critical commitments made by all the countries of the world in Paris, three years ago (2015).

The conference, which coincides with the three year anniversary of the Paris Agreement adoption, is expected to finalize the rules for implementation of the Paris Agreement.


COP24 is looking at concrete ways to help countries tackle large-scale displacement caused by the impacts of climate change, including water scarcity, flooding, storms and rising.




COP24 Climate Change

As global temperatures continue to rise, climate action is lagging and the window of opportunity is closing. On Sunday, the United Nations kicked off critical negotiations on how to address the problem collectively and urgently, during a two-week climate change conference in Katowice, Poland, known as COP24.

According to scientific research assessed by the IPCC, keeping global warming to no more than 1.5°C global average over pre-industrial levels, will help stave off devastating permanent damage to the planet and its people, including: 

  • the irreversible loss of habitat for animals in the Arctic and Antarctic; 




COP24 Climate Change
UN News put together this guide to COP 24 to answer some of the biggest questions you may have and make sure you’re all caught up, with a ringside seat on the action. 
To limit COP24’s footprint and achieve carbon neutrality locally, the conference organisers have taken a series of different measures. First, public transportation in the city is free of charge for the duration of the conference, for all participants. 
In addition, reusable materials have been used to set up the conference rooms, including carpets and backdrops. Recycled cardboard furniture was installed in all the main meeting spaces. 


Sir David Attenborough delivered a stern speech at the UN's climate change summit in Katowice, Poland, on Monday morning, warning of the impending threats global warming poses to the natural world.
"If we don't take action, the collapse of our civilisations and the extinction of much of the natural world is on the horizon," 
Sir David Attenborough

Education:
Last week thousands of students sacrificed a bit of their education to demand climate action.

Education is the most powerful way to continue developing green generations. Greta 
Thunberg, a Swedish 15-year-old with Asperger Syndrome, is a good example. She's on a school strike to get politicians to act on climate breakdown.






Well, I don't agree with the school strike. I think students could have their voice without striking school time.

Thus, this new generation, the ecology generation, is seriously committed on climate action. And they have a voice! They are engaged with COP24 Climate Change,

I know, the eyes of schools are on COP24 Climate Change. Teachers and students are working on climate change






ActNow.BOT


Resources & Activities for schools:

Sir David Attenborough launched a new UN campaign to give individuals their say on the key global issue, via social media.


The UN’s new ActNow.bot [this link opens in Facebook Messenger] is designed to fuel climate change understanding, and urges advocates to take personal action via the Facebook Messenger Platform.
The bot is a fully interactive and responsive chat bot which students can find on the UN Facebook page. 
It suggests everyday actions determined by the user’s - and why not schools, teachers and students - interaction with the bot, that can be taken to preserve the environment and shared via the social platform to encourage collective action.

The Climate Action ActNow.bot (link opens Facebook Messenger) recommends everyday actions – like taking public transport and eating less meat – and track the number of actions everyone individually is taking. 
By sharing Climate Action progress with your students on social media, schools can help encourage more schools and students to ACT NOW






The campaign highlights the impact that collective action can have at this critical moment in our planet’s history.

Sir David told delegated on Monday 3 December in Poland that “if we don’t take action, the collapse of our civilizations and the extinction of much of the natural world, is on the horizon.”






So here you have some resources to include into school curriculum. How about the People's Seat?


A UN campaign called the People's Seat has been established to represent the world's population before a council tasked with putting the brakes on global warming.
Speaking for The People’s Seat initiative, Sir David Attenborough called it the result of new activism shaped by people from around the world and collected through social media.


People’s Seat initiative aims to engage people on taking action climate change in the lead-up to the Katowice Climate Change Conference. The initiative will combine digital technology, polling and the voices of prominent environmentalists to deliver an urgent message to delegates at the conference.

The UN is inviting people from all over the world to share their thoughts, opinions and experiences with climate change by using the hashtag #TakeYourSeat. 


These messages will help to shape the People’s Address, which will be delivered by Attenborough to the conference on the day.





Students Time to Act!

Time to Act? So, invite your students to takeTheirSeat and share some thoughts, opinions and experiences with climate change. Don't forget the hashtag #TakeYourSeat. 

Their messages will be delivered by Sir Sir David Attenborough. 


The world’s students and schools can take part in creating videos and voicing their opinions. Teachers and students must take part of this unique opportunity.




The Lazy Person's guide to saving the world:

It seems impossible that the average person can make an impact. Should you just give up? No! Change starts with you. Seriously. Every human on earth - even the most indifferent, laziest person among us - is part of the solution. 

Fortunately, there are some easy things we can adopt into our routines that, if we all do it, will make a big difference. 

Have a look at just a few of the many things you can do to make an impact! 

Teachers, download the guide and invite your students to do some simple things and they will make an impact!
