We heated coal in a test tube. gas came out and it smelled bad! We lit the methane gas on fire.
1.seperate solids) magnet, dissolve one, gravity,flotation,sorting,sieve
2.seperate soloution)distil, evaporate,density
3.suspension)=solid settles to bottom
filter)tiny holes let small particles pass but stops big particles from passing through. Decant)Centrifuge)
1.now we have to seperate iron filings,sand and salt
method 1)put the mixture in the evaporate dish and put the magnet over it and that will pick up the iron.
then make it into a liquid
We made wine by fermenting glucose, to make CO2 and Ethanol. We used yeast. The next day we distilled the wine to make pure alcohol, which we dripped out and set on fire.
We dissolved Copper Sulfate in 50ml water, then boiled it to dissolve more. Then we tied a crystal on a string, and put it in the solution to make a bigger crystal.
We used dry ice today. It was awesome.
We made oxygen from hydrogen peroxide bleach. We lit a splint and blew out the flame. In oxygen it caught fire again!
We split up a compound, copper chloride, using electricity. This is called electrolysis. We made stinky, poisonous chlorine gas bubble. And red-brown copper stuck the the carbon electrode.
We make models of compounds using balls and write formula for them.
Stinky sulphur, magnetic iron and rotton egg hydrogen sulfide. Awesome!
