Born in England, Priestley was involved in political and religious activities, as well as dedicating himself to science. His support for the revolutions in France and the US, public and notorious, made staying in England not a safe option. In 1794, Priestley had to leave his country and worked in the newly formed USA until his death.]]> 2021-09-23 18:12:50 UTC https://padlet.com/abdelnourvale11/jq5oiupn2xea9o1o/wish/1763773087 abdelnourvale11 https://padlet.com/abdelnourvale11/jq5oiupn2xea9o1o/wish/1763779224 Do you need oxygen?
Hello, I introduce myself my name is Valeria and today I am going to tell you why oxygen is so important and why do we need it? We get oxygen from trees and in tanks in hospitals. Oxygen is necessary because we live with that. It is as necessary as water. In the case of hospitals, they use tanks to keep people who are injured or seriously alive. The tank can also be used at home since there are people who find it difficult to breathe and need tanks to breathe and not lose their life. and you, would you buy a tank or take care of the trees?]]> 2021-09-23 18:15:42 UTC https://padlet.com/abdelnourvale11/jq5oiupn2xea9o1o/wish/1763779224 abdelnourvale11 https://padlet.com/abdelnourvale11/jq5oiupn2xea9o1o/wish/1800554771 2021-10-07 17:31:48 UTC https://padlet.com/abdelnourvale11/jq5oiupn2xea9o1o/wish/1800554771
