Look over the next 8-week chemistry course. How many elements can you list from your head?
Do we have, in the house...
calcium
chlorine
copper
flourine
iodine
iron
magnesium
sodium
zinc
Look on the labels for cereal, toothpaste, tinned goods, dried foodstuffs. Check out mama's headache tablets and your Calpol.
See if you can work out or find out what these are:
NaHCO3
SiO2
Mg3Si4O10
Au
FeS2
I can help with one of those. Try gold.
