3 facts I have are that 1.Stephen Gray divided the world into two different kinds of substances conductors and insulators. 2.300 years ago Stephen Gray created a machine that could generate static electricity. 3.Glass, ceramic objects and silk are just some of the materials that insulate electricity.
2 understandings that I have now are that 1.Insulators hold the electric charge and 2.conductors let the electricity move freely.
A question I have is that why did Gray use an orphan to lie across the swings and not a random person?
Three facts I have are that weedy seadragons are native to Australia and can be found in the waters mostly off the South and East coasts. Researchers researching weedy sea dragons are using a kind of facial recognition software to identify each fishes’ unique patterns! Every time researchers identify a new weedy seadragon, they give it a very appropriate name to help keep track of it!
Two understandings I have are that weedy sea dragons are related to sea horses and often just drift about in the water, blending in with the kelp around them. Right now weedy sea dragons are classified as ‘near threatened’ but scientists that are researching the topic think that they might have to be re-classified as ‘endangered’. Rising sea temperatures is the thing that is killing the kelp which leaves weedy sea dragons homeless.
A question I have is how long have weedy seadragons been around for?
Three facts I have are that the mother Tasmanian devil gives birth to about 30 joeys. But the mother has only four teats so usually only four of the joeys make it. It was believed that Tasmanian devils died out across mainland Australia about 400 years ago.
Two understandings that I have are Tasmanian devils’ population has been cut by more than 80% and they’ve made it onto the endangered species list because of a disease called the Devil Facial Tumour Disease.The disease is a special type of cancer because it is contagious. And that because the tumours build up around the animal’s face and mouth it can’t eat and it starves to death. Once a devil gets it, the devil usually only has about six months to live.
A question I have is why are Tasmanian devil mothers less pregnant in captivity?
Three facts I have are that the internet can be traced back to the 1960’s in the US. In 1989, Tim Berners-Lee created a system used for sharing information on the internet and that around 3.2 billion people around the world use the internet.
Two understandings I have are that when you send a picture overseas firstly it turns into about a million pieces, then sent to the other end where the picture stitches itself back up.
Most of the cables that connect the internet are under the sea rather than using satellites, because the cables are more reliable to use.
A question I have is that why would the entire world depend on only the cables under the sea for the internet and not have a backup way?
Three facts I have are one in every three Australian citizens will need donated blood at some stage in their lives. That there are about five litres of blood in the human body and once the blood is in the hospital the blood can be used for 22 different medical purposes.
Two understandings I now have are that there are two different types of blood; plasma and platelets. Half a litre of blood can save three lives.
A question I have is that are there any more types of blood?
3 facts I have are that Pluto is smaller than our moon. Pluto was named a dwarf planet because it was too small. A group of scientists think that instead of having 9 planets we should have 110!
2 understandings I have are that the scientists think that a planet should be called a planet because of the characteristics or texture of the planet. If Pluto is made a planet again then we shall have to learn lots more names of all the new 102 planets!
A question I have is why were so many people sad when Pluto was made a dwarf planet?
Anh Doh came to Australia by boat when he was 2 years old. The boat trip took 5 days and they got rescued by a German ship. But to get on the other ship they had to bash a hole in their boat so that they could be rescued by the German ship because the Vietnamese refugee’s boat was sinking.
When Anh Doh came to Australia he landed in a port in Sydney. Anh Doh’s uncle was a landmine clearer in the Vietnam war.
A question I have is why the Vietnamese refugees had to sink the boat that they were on?
3 facts are that on 1 January 1901 all the states officially joined together to make one country: the Commonwealth of Australia, northern territory and the ACT were added later and women couldn’t vote until 1902.
2 understandings I now know are that aboriginals couldn’t vote until 1962 and weren’t counted as part of Australia’s population until 1971.
1 question I have is if the Dutch had stayed in Tasmania could we be speaking dutch right now?
Three facts I learnt are that captain cook claimed new south wales for England in 1770 and that around about 20 out of 700 convicts would not survive the trip. I also learnt that aboriginals thought of cows as beasts.
Two understandings that I understand are that you could be hanged for stealing bread and that lots of kids who weren’t earning enough took to thievery.
One question that I have is why were England’s laws in the 1700’s so harsh?
