Chemistry and electricity
1) copper is the 2nd best electricity conductor
2)Silver is the best conductor for electricity
3)Electricity is mostly made up of electrons
4)The element Uranium powers thermonuclear power plant
Astronomy and ecology
1)As the economy produces green house gases the atmosphere gets damaged and there is global warming.
2)electrons orbit the nucleus like planets orbit the sun
