Well I've just finished my highly exciting science homework, so, to show you lot how much fun I've had... I decided to post it!
Aim: To find out what happens when iron and sulphur are heated together.
Diagram:
Equipment: Tongs, goggles, test tube, iron, sulphur, mineral wool, Bunsen burner, paper, heat proof mat and a magnet.
Safety: Goggles worn at all times and ties tucked in. Don't heat the mixture for too long.
Method: 1. We measured out 1 spatula of iron and sulphur, then we mixed them on the paper, recording our observations.
2. Then we put the mixture in to a test tube and ran a magnet up the side. We recorded observations.
3. The bunsen burner was lit.
4. Then we plugged the top of the test tube with mineral wool and held it over the bunsen. (Which was at half flame) We heated it until it glowed.
5. After the test tube had cooled down we ran a magnet up the side and recorded our observations.
Results:
1. When the two elements were mixed on the paper a greyish yellow mixture was formed.
2. When the magnet was run up the side of the test tube the iron filings leapt up from the bottom and followed it around. The sulphur that was trapped in between the iron, rose as well.
3. After the mixture was heated, two new compounds had been formed. Sulphur Dioxide. The sulphur had turned in to a gas and risen, popping the wool off the top of the tube by it’s pressure and leaving a yellow ring around the top of the test tube. Iron Oxide was also made. The iron filings had been turned to a black solid.
4. When we ran the magnet up the side of the test tube again we found that the Iron Oxide was not magnetic and would NOT follow the magnet around.
Consclusion: Before: It was a mixture of a metal and a non-metal. The mixture was magnetic.
After: There are two new compounds. We know this from: The colour change. We have seen energy being released (The wool being popped off the top of the test tube) It is now non-magnetic.
These are all NEW PROPERTIES.
The equations for these compounds are: Iron + Sulphur = Iron Sulphide and Sulphur + Oxygen = Sulphur Dioxide
*yawn yawn yawn yawn*
Why DO we have to go to school?

Fine you got that one BUT.... can you answer these.
How was Pluto discovered?
How was Planet X discovered?

So I didn't do too badly then :-)
Roid' belt is between Mercury and Pluto.

yeah I didn't have a clue about that one :-) Got Mars right though...

not to bad for a guess but inner planets : mercury venus earth mars ASTERIOD BELT outer planets: Jupiter saturn uranus neptune and pluto.
i win i win!!! prove me wrong this time!?

Jupiter is an outer planet. Roid' belt is between Mercury and Pluto. Or between Mars and Jupiter, if you want to be more specific.

I don't know. It isn't pluto though. Pluto's in our solar system, so it can't be the furthest planet that there is from our sun. ;)

I think you'll find that Uranus has rings around it as well as Jupiter, so I deserve full marks for that!
RBS: Constantly cheeking teachers... heh, you should see me in my maths lessons!
