Atoms & Molecules
1) What is C? H?
2) Can you name an element?
3) What four elements are elephants mostly made of?
4) What four elements are humans mostly made of?
5) What compound are humans mostly made of?
5) Can you name a chemical compound?
6) Is Fe O (Iron Oxide) a compound or an element?
7) What is Fe O ?
Solutions
1) Salt water: which is solute and which is solvent?
2) How could we separate the solution?
3) What is the name of the saturated solution that we used when making slime?
Polymers
1) Who can name a polymer that we discussed today?
2) What makes some polymers sticky?
3) What other polymers do we encounter every day?
