i always used the inquiry a diet soda and the same brand non-diet and they
have to infer if they will sink or float on paper. i place them in a see
thru container, a 15 gallon aquarium works well and the students watch what
happens and they write 3 reasons why this occurred. the diet floats, the
regular one sinks. then we weigh them and discuss. i take 3 packs of sugar
from resturants nutra-sweet, sugar and nongranulated sugar and we weigh them
individually.........jann
