Here is our latest podcast about the Earth's atmosphere. I hope you like it.
Hi everyone, this is our next podcast and it's about BLACKHOLES! Blackholes are important because without them, there would be no galaxies.
We had an amazing fossil hunt on Labour Day. It was on Monday, 26 October 2015.
The fossil hunt was at Fairfield Quarry. We started in the morning. The weather was good.
Amadeo organised it. We did it because we were in the astronomy club of Dunedin. We were looking for iridium and fossils. We were hoping to find ammonites, leaves, dinosaur bones and seeds.
We needed a hammer, a box to keep the fossils we found, newspaper to wrap them in, a back pack with a water bottle and lunch, suncream lotion, a camera, and boots and clothes that we could get dirty.
A fossil hunt is when we look for fossils. Fossils are life that have mostly turned into stone. Fossils are quite common in some places.
We drove about 15 minutes. When we got there, Amadeo gave us safety vests, safety goggles and hard helmets, and they were harder than bicycle helmets. There was a danger sign that said "Danger: Soft mud. Risk of drowning". That's why we had the safety vests, because the colours are very light and easy to see against the brown. So they keep us safe in case we get stuck in the mud.
Amadeo and Conor got trapped in the mud. But luckily, the rest of us pulled them out. Because of that, I took off my shoes so that I wouldn't lose my shoes in the mud. There was a lot of gorse and prickles. I stepped on a lot of the prickles and got nine splinters in my right foot.
At first it hurt a lot, but after a few days I didn't notice it.
We brought out hammers because the rocks were very hard to crack. Inside the rocks there might be fossils. But we didn't find any fossils in the rocks. We found some small chunks of fossilised wood on the cliffs. There was quite a lot of it.
There was also a big lake. There were ducks and big seagulls. We threw some of the rocks into the lake. They made big splashes.
There were a lot cracks in the mud and in the them there was a lot of prickles.
Then we had to go because I had too many splinters.
These are the pieces of fossilised wood I found. They are about 65 million years old.
Donn, Conor's dad, found this big chunk of fossilised wood. It was slightly smaller than my hand.
On Friday at the observatory, we had to return all the safety gear. The fossil hunt was lots of fun, except for the splinters.
Next time, I hope to find ammonites and leaves.

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.
