Hi Miss Florence,
This video talks about a scientist in the 18th century which discovered the oxygen by putting mercury( which was an unexplored chemical) on something that looked like a round bottomed flask and heated it and took out a certain gas which later he showed it to other scientist and they finally agreed that that strange gas was oxygen. All this was told by a man who had photos that you could see the oxygen.

See you,

Miss Florence,

This video talks about a scientist called Joseph Presley which in the 18th century conducted a series of experiments searching for new airs (gases). This man new EVERYTHING. He wrote books about lots of subjects. Mercury (liquid and metal) and electricity were used for the experiment. Presley took a burning glass, heated it till it ended, he focused it in the orange powder, he heated it, it changed into this metal mercury and a gas came off. In 1774 Presley took a visit to Paris and shared the story of his discovery with another scientist called Auntan Levassue. (I don’t know how to write the scientists names). That’s what the video talks about.
Hope you liked it.
Bye, bye, see you in school.

This video is about a scientist called Joseph Presley that made an experiment in search of new airs (gasses).He wrote about politics, science, religion, history etc. They said he knew all. For this experiment he used two very important materials, mercury (liquid metal) and electricity. Presley took a burning glass, he heated it until it finished, he focused it in an orange powder and he heated it, it changed into the metal mercury and finally the gas appeared. Having his new experiment, in 1774 he went to Paris to show his discovery to another scientist “Antoine Levassue’’. And he was the discovery of this new gas.
I hope you like it, see you tomorrow.

Hi Ms. Florence,
The video is about the discovery of oxigen done by Joseph Priestley. He was an english scientist that wrote many books on different subjects like history, religión, politics and specially science. He used to experiment with mercury, a liquid metal, in which many people was interested in that time. He heated mercury and with Mr Antoine Lavoisier,a french investigador they discovered that this gas was oxigen.

Hi Miss Florence,
This video talks about Joseph Pristley, a scientist. He wrote about many subjects. He made to find out about airs, which we now call gases. He made a famous experiment with mercury, a "liquid metal". He used tubes you could see through. In this famous exoeriment he obtained a gas he didn't know what it was. Later he shared his findings with Lavoissies... He had discovered Oxygen.

In the 18 century Joseph Presly, did some important experiments searching for new airs that now we call gases. He was a very intelligent man that new about history, politics, religions, sience and wrote books about his knowledge. He discoverd oxygen when he heated mercury, and a strange unknown gas was seen and when he when he travelled to Paris he agreed with another scientist that, that gas was oxygen.
