Doin' It At Home: Chromatography:
Here are some alternate directions for doing the experiment at home. You have the option of these experiments:
- Candy Chromatography - if you happen to have skittles and M&M's around, or your mom is willing to indulge... http://www.education.com/science-fair/article/chemistry_paper-chromatography/
- OR>>>Leaf Chromatography - now that we have leaves about to turn color, this is a great experiment - http://chsweb.lr.k12.nj.us/mstanley/materials/chromatoglab.pdf
- OR-- If you have round coffee filters http://uncw.edu/chem/courses/reeves/onlinelabs/Paper%20Chromatography/PaperChrom_exp.htm
- OR--the handout from class, which uses permanent markers and ethanol, but any solvent like rubbing alcohol or nail polish remover will probably work. Adapt to whatever container you have.
- OR--most difficult one - Crime Scene Investigation - but you can do it ! = http://www.msichicago.org/fileadmin/Education/learninglabs/lab_downloads/EvidenceLab_ink_act.pdf
- NO MATTER WHICH EXPERIMENT YOU DO, use the handout to tape your strips to and answer those questions, as best applies. Print out whatever experiment you use, staple all together to turn in on Thursday.
And some online reading: (summarize briefly in your journal).
