|I designed an experiment investigating the
effects of temperature on viscosity of honey. My
experiment doesnt seem to work and I need help to
modify it. My method is:|
Method: 1) Put 5
ml of honey into 4 separate beakers.
sure the temperature of honey in all four beakers
is different by using hot water bath to get it to
a higher temperature and ice bath to lower the
3) Label each beaker 1, 2, 3 and
4 and measure the temperature of honey in all the
4) Dip a paper clip in the beaker for
five seconds and place it on separate evaporating
5) Use a magnet to pull the paper clip
right above the evaporating basin.
6) Using a
stop watch, record how long it takes the paper
clip to drop onto the evaporating basin.
Do the same with beaker 2, 3 and 4.
steps 4, 5 and 6 three times to get an
I think methods numbers 5 and 6 have
problems. The paper clip does get attached to the
magnet but it doesnt drop back.
1.- Will you
please suggest something?
2.- I was wondering
if I should use a magnet of low magnetic strength
or if I should use a heavier metal?
you please help me and reply as soon as possible?
There are some aspects of your experiment that are
very well designed.
For example,taking four
sets of data (step 8) to get an average, and using
hot water or ice baths to achieve different honey
temperatures (make sure you leave the honey in
contact with the hot water or the ice for long
enough, though, to be sure that it has
equilibrated to the water temperature!)
not sure what you had in mind with the paperclip
though. Paperclips are made of iron, which becomes
magnetized in the presence of a magnet; as you
point out; this allows you to pick up the
paperclip using the magnet. The magnetic
interaction between the paperclip and the magnet
is unlikely to be affected by the honey (unless
you coated the paperclip so thickly that the
magnet couldn't reach it, in which case you'd
struggle to pick it up in the first place). So
this won't be a good measure of the honey's
So instead you need to think
about something that you can measure, that will
change (preferably by a lot) when the viscosity of
the honey changes. Remember that things that are
less viscous are more "runny". So if you want to
stick with your current experimental set-up, you
might think about obtaining a measure of how easy
it is to move the paperclip through the honey, or
how quickly the honey runs off the
Good luck with your experiment!
