Astronomy and chemistry
1)Stars are made up of mostly hydrogen and oxygen
2)Uranus is mostly made up of frozen methane
3) The sun is made of hydrogen (74%) and helium (about 24%)
4)The ''BigBang" created every element on Earth
Chemistry and ecology
1)The fertilizer DDT is an organic compound, with chemical formula C14H9C15
2)sulfur dioxide is an air pollutant
3)If uranium causes radiation in an area and there is life in that area, it will all die
4)
Electricity and ecology
1) thermoelectric plants cause pollution to the environment
2)Satellites in space use solar panels for electricity
3)Alternative energy sources do not cause pollution to the envirement
4)
Electricity and astronomy
1) Satellite in space use solar panels for electricity
2When cold air and hot air meet it makes lightning
3)electrons orbit the nucleus just like planets orbit the sun
4)
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 plants
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
3)When plants photosynthesise they turn CO2 and water into Hydrocarbons for food and release Oxygen.
4)The sun is one of the reasons that their is life on earth
