Hi everyone, this is our next podcast and it's about BLACKHOLES! Blackholes are important because without them, there would be no galaxies.
The "Luminescence: The Spectrum of Light" science festival is the best thing ever. It took place on Saturday, 18 July at the University of Otago, Dunedin, New Zealand in the Southern Hemisphere on Earth.
My mum went with me. I got to get glow sticks, and got to have a Milky Way chocolate bar after the laser maze.
My favourite part was the liquid nitrogen. I became a dragon and I breathed fire by eating frozen Twisties that had liquid nitrogen poured on them. Liquid nitrogen is a water gas. If you pour it on the ground it will become gas. But if you keep it in the bottle it will be watery.
I ate frozen gummy worms. Before you eat them you have to drop them, and they will shatter like bits of glass. The liquid nitrogen sucked out the moisture from the gummies.
I went to a talk about how black holes influence light. It was very fun. At the talk, I saw my friend Ada. I learnt that if a large object is in between the path of the earth and a supernova, we will see the supernova in four places at different times. I learnt that black holes, when they have sucked a star in, they have an accretion disc. Accretion discs are discs around a black hole.
I asked a question. My question was "what happens inside a black hole?" No one actually knows the answer because nobody has been inside a black hole.
I played with fire. I sprayed different kinds of liquid chemicals like copper sulphate and sodium chloride onto a flame. I had to wear goggles. One of the chemicals made the fire green, one made it go orange, and one made it go red.
I also made a kaleidescope. It was very fun.
I want to learn chemistry.
This is my latest documentary about the conjunction of Jupiter and Venus. Hope you enjoy it.
The Beverly-Begg Observatory is a very fun place. You can see lots of stars from it. They have a laser beam that can shine all the way to the stars.
There are some 3D photos of the universe that you can see there. They have different types of telescope lenses, and they had a camera you can attach to the telescope to take images and videos.
This is a map of the moon. It shows all the craters.
I was looking through binoculars at the Beverly-Begg Observatory, while the astronomers set up their telescopes. I saw the Southern Cross, Jupiter and Sirius. I also saw a big cluster of stars.
When the telescopes were set up, we saw lots of amazing stuff, like:
We also saw an Orrery. It has all the inner planets - Mercury, Venus, Earth and Mars. The Orrery also had the sun (the lightbulb).
We joined up as members of the Beverly-Begg Observatory. It's a very cool place.
"This is my third documentary, all about the parts of the universe that are cool. Many are deadly." Jordan
Note from Jordan's mum: Jordy wrote and typed this up himself over the last week or so. We helped him with spelling and formatting.
He got his information from a pretty cool Discovery channel documentary series called "How the Universe works". Highly recommended viewing for anyone interested in what is out there in the great beyond!
"My name is Jordan. I am eight years old. I am interested in nature and the wonders of the universe. I like making documentaries. My favourite things are volcanoes, dinosaurs, life, fungi and mushrooms, spiders, coding and the universe."
