cockydude Posted July 15, 2006 Report Share Posted July 15, 2006 Well i have got the next 2 years to do a realistic science project and write a 3000 word essay on it, but i have no idea what i want to do, preferably something bio-based, narrow in scope, not too heavy and not to deep. Anyone care to suggest any patricular topics they have done? Quote Link to comment Share on other sites More sharing options...
hallenrm Posted July 15, 2006 Report Share Posted July 15, 2006 What are the ideas that you have in mind, perhaps after this little information people here can help ou better. Quote Link to comment Share on other sites More sharing options...
cockydude Posted July 15, 2006 Author Report Share Posted July 15, 2006 Ahhh. let's see i think something to do with genetics should be fine. I have a nice genomics and proteomics lab in school. It should be something experimental. Or maybe something to do with enzymes, it seems to be the in-thing. Quote Link to comment Share on other sites More sharing options...
UncleAl Posted July 15, 2006 Report Share Posted July 15, 2006 CHEMISTRYhttp://jchemed.chem.wisc.edu/ Journal of Chemical Education; search. Pick your experiment. Dyed crystals are nice. Ferrofluids make great demos. Then visit an academic science library and start xeroxing. PHYSICShttp://www.fourmilab.ch/gravitation/foobar/ Mount a laser pointer on the bar. If the bar twists the spot will move on a distant screen with displacement amplified by distance. If you get clever, can you put a first surface or dielectric mirror on the bar and use the laser pointer to create an optical interferometer? Count fringes.

It's colonies are white to brownish. Serratia marcescens is deep red. Sarcina lutea is bright yellow. Chromobacterium violaceum is a lover, http://cmr.tigr.org/tigr-scripts/CMR/GenomePage.cgi?database=ntcv01http://web.umr.edu/~microbio/BIO221_2000/Chromobacterium_violaceum.html http://www.pelletlab.com/living--bacteria.htmhttp://www.sargentwelch.com/product.asp_Q_pn_E_WL23814_ST_A_Basic+Pigmented+Bacteria+Set_E_Pigmented bacteria sets Grow a batch of colored bacteria. Extract their DNA. Expose damaged growing yeast to the DNA (e.g., remove cell walls, then electroporation, then recovery) and see if you can get mutated colored yeasts. Or just plate the little fellas (and mixed cultures) and blast with UV (blacklight, UV B, germicidal UV), charting survival and dominance vs. UV dose and color, http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=14067916&dopt=Abstracthttp://www.epa.gov/wed/pages/publications/abstracts/archived/tong97.htm BRUTE FORCEGnuplot makes lovely 3-D plots and its free, http://www.gnuplot.info/ All you need is something to plot. Bicycle pump, pressure gauge, graduated cylinder, empty 1- or 2-liter drink PET bottles, a videocam and vertical calibrated stick, some minor cleverness Vertical axis is maximum height. One axis is milliters filled with fluid. One axis is pressure. What is the response surface? Cf: theory of experimentation. Buy a jug of glycerine (viscous!). At best pressure, how does height vary with liquid viscosity? DIDDLINGGet a box of cornstarch. Mix a cup of cornstarch with a cup of water being careful to get it smooth and fee of lumpls. Why is that an interesting fluid? Corn starch, water, cheap speaker, oscillator. Dip a rod, vane, or horizontal disk into varying ratios of cornstach and water. Dipper is connected by a vertical shaft to the speaker. One axis is water/starch ratio, one axis isprobe velocioty (from frequency and length of thrust), one axis is mechanical resistance (be clever, as with phase shift or reactance, or a piezoelectric readout). ronthepon and pgrmdave 2 Quote Link to comment Share on other sites More sharing options...
