Some people seem to have done a good job of making both their density column and their calculations, but the column and calcs didn't match!!! How can that be? Where could they have gone wrong on the density calculations? How could the column turn out differently than what they calculated?

I don't know Mr.Casey! We had trouble at first but then got help. We turned in our column late but did the project on time. I'm gonna redeem myself on the next lab.

Well, I want to give credit to those that can analyze what may have happened. Can anyone (or Lothar) speak specifically to what could have gone wrong?

I am going to be honest that was my group we seemed to be running low on time and when we had everything for a perfect 5 we rushed through our column and didnt pay attention. Came out with a three, its well average but not the grade i was looking for.

So when you say I didn't pay attention, what does that mean? What could have been better about what you did?

some people may have put more liquid in for the volume which could counteract your results in the division of mass and volume which i think our group may have done wrong

I think I know what you mean Chase, but can you explain how recording, and calculating with, too much volume could screw up your results?

we got a three because our calculations where backwards and we didn't have enough time to recalculate so we went for it and hoped for the best. Afterwards we realized that our calculations on the liquids were partly correct but our solids weren't.

Mr. Casey I think that people's density columns might have been wrong because they could of calcualted there liquiuds wrong. Also, they might of mized up their calculations because I know that me and my group got our data mixed up, but then we fixed it.

i dont know if this is what you want..but my mom has always use palmolive dish soap, and she asked my dad to by some dish soap, and he came home with dawn. so my mom mixed the two together thinking they would mix. the next morning the container of soap had the green(palmolive)soap at the top, and the blue(dawn) soap at the bottem. so i think this is what we did in class with the density colums!!!

Our denstiy colum didnt turn out as well as i thught it was going to. i think it was bacause a lot of the liquids wieghed the same amount.

Our density colunm worked except for the solids i think we messed up our calculations

i think that maybe they might have measured the liquids wrong or miscalculated the mass of the objects. my group made that mistake on miscalculating the mass of the objects. i learned to double check my work from that.

On our density column i noticed that we had some wrong calculations as well, and we noticed that when you would put a liquid with a higher density over one with a lower density it would jut slowly switch places so we went back and retested the liquids and figured out that we just misused the triple beam balance.

One way we had trouble is we could find an object to accurately float in the middle also two of our liquids mixed together and you could barely tell the difference Comments are closed.
