Students Answers:
Axel P. - Caffeine is an element because it has all of the same types of atoms in it, just mushed around and stuff.
Sophia - Caffeine is a compound. Based on the picture, we see different types of atoms bonded together, exactly like what you would see in a compound.
Julian Jimenez- Caffeine is compound because all of the atoms that are chemically combined are of the same type. Same type = compound.
Aiyanna - Caffiene is an element because it is the purest form of what it can be.
