Don't forget that your samples must be small and THIN (flat). If the sample is too big/thick then no light will pass through to the lenses.\nMost things are best viewed after mounting them in a drop of water under a cover slip.\n\n1. Crystals of salt, icing sugar, etc.\n2. Fibres of cotton, wool, synthetics, string, etc.\n3. The torn edges of paper.\n4. The individual dots of colour from non-glossy pictures. You will probably have to add a bit more illumination from above the sample for this by shining a light onto it (e.g. desk light).\n5. Leaf 'skeletons'.\n6. Living leaves - from a potted plant (e.g. a 'spider plant') bend the leaf and clip it between two slides. (Additional top illumination needed.)\n7. The thin 'skin' from between the 'leaves' of an onion (onion epidermis).\n8. The edge of a razor blade or sharp knife (with top illumination).\n9. Strands of spider webs.\n10. Dust.\n11. By gently using a potato peeler you can make thin sections of all sorts of plant parts. Usually only the very edges of these sections are suitable for viewing. You might like to stain plant samples with a drop of iodine (use instead of water) under the cover slip.\n12. If you have a wood-plane then make thin samples of different types of wood.\n\n(P.S. Forgive my UK spelling)

You can get disposable, sterile swabs.  These would probably work the best.  You should be able to get them via online... google "lab equipment swabs".\n\nopen your swab, being careful to not touch the tip.  Run the swab over the section you want to culture.  Then, simply smear the swab onto the petri dish.  \n\nFor the petri dishes, you probably want more than just an empty dish.  You want an agar plate.  An agar plate is a gelatinous material on the bottom of the dish that provides food and nourishment for the bacteria.\n\nYou could probably use gelatin as a stand-in.  Buy plain gelatin and make a batch twice as concentrated as it should be.  This will make the gelatin harder and less likely to melt at room temperature.\n\nGood luck!

With a hot directed flame you can shape glass and make the lab equipment that you need. In a glass factory glass is made into all different shapes. Glass tht we know is really a liquid. You cansee this in an old window that has become rippled.

GOLD-PLATINUM-PALLADIUM TEST\nBy Delos Toole\n\nSelect ore samples suspected to contain Gold-Platinum-Palladium and use concentrates equal to the size of one navy bean or pea. Place the concentrates in a clean test tube and add 1cc Nitric Acid and 3cc Hydrochloric Acid, (this a solution named Aqua Regia which is used regularly when testing.) Boil this over a lamp flame for about 5 to 8 minutes. Should this Aqua Regia solution contain Gold-Platinum-Palladium then the following tests will react with various colors, (good idea to practice on known samples of Gold-Platinum-Palladium for color and reaction identification and become familiar to them.)\n\nTest for Gold (Au).\n\nPrepare a solution for Stannous Chloride for each 8 hour period as this solution does not hold up under extended time periods. Dissolving Metallic Tin (Sn) in Hydrochloric Acid (HC1), where the resulted solution will be called Stannous Chloride (SnC1). Place about 2cc of HC1 in a clean test tube and add 1 or 2 small bit pieces of Metallic Tin to the test tube and bring this to a slight boil. You now have Stannous Chloride (SnC1).\n\nNow begin the gold test by making a spot test with freshly made Stannous Chloride by placing a piece of filter paper onto a clean piece of glass and place one drop of Aqua Regia solution in the center of the filter paper, and then add to this mixture one drop of freshly made Stannous Chloride solution. If gold is present there will show up on the filter paper a purple or rose colored spot when the filter paper has dried; the darker the color the more gold will be present; for low grade ore the spot color will appear plainer. Should the filter paper dry out completely, then add 1 more drop of Stannous Chloride solution to the filter paper to bring out the color.\n\nBegin the test for Platinum (Pt) by placing 20 drops of Aqua Regia solution onto a clean porcelain evaporating dish and boil this over a lamp flame until it is dry, then allow this to remain over the lamp flame for about an extended one second.\n\nPlace the dish where it can cool for a few minutes so as not to break the dish. After cooling, place 4cc of distilled water, (or water free from Chlorine), and reheat just to the boiling point. Filter this solution onto another clean porcelain evaporating dish. Add to this dish, Potassium Iodide equal to one grain of rice. Warm this solution slightly over the lamp flame and observe the color that appears. The results for this test will show if Platinum (Pt) is present as the solution will begin to turn to a light or dark rose color within a few minutes time.\n\nThe more Platinum present in the solution, (ore sample), the quicker and darker the color will appear.\n\nSulphides and other impurities, most likely will give a red color to the solution and will be mistaken for the rose color, if so, then boil off about one-half of the solution to quicken the evaporation process. Then let the porcelain dish set until completely dry, then add a few drops of clean plain water, (no chlorine water). The result will then be a bright rose color, and should there be Sulphides or other impurities in the solution they will appear as colorless. If this solution should appear red, then add a few cc’s of plain water to dilute the dark rose color to a lighter rose color, then you have Platinum (Pt).\n\nTesting for Palladium(Pd).\n\nIn the test for Platinum (Pt), upon adding Potassium Iodide (KI) and warming the procedure, if Palladium (Pd) is present in the sample ore, the solution will turn a dark color or black, which depends upon the amount of Palladium (Pd) present. The more Palladium (Pd) present, the darker the color will be, and also there will be a black precipitate in the bottom of the porcelain dish, which when adding an excess of Potassium Iodide (KI) will dissolve giving a wine-red color appearance.

You could do what I did:\n\n1. Get UNFLAVORED geletin (like Jello, only with no color or taste), and mix it up. Put several samples into rubber maid containers and seal it.\n\n2. Buy several different kinds of sanitizer (Lysol, different scents of lysol, Pine sol, and those clorox wipes.).\n3. Get BRAND NEW Q-tips, and swipe areas you want to swipe (ie bathroom counters, toilet seats, under neath the toilet seat, faucet handles, kitchen counters, kitchen sinks...). Remember which Q-tips are from which room, and swipe the Q-tips all over the different geletin. (MAKE SURE you keep bathroom and kitchen Q-tip samples distinct. Mark on the bottom which ones are which) WAIT FOR A FEW DAYS. This will allow the germs you have collected to grow and get happy.\n\n4. Get some of those paper coffee filters. Sterilize a paper punch with a lighter, and punch one little circle for each sanitizer you want to test. \n5. Dip the different circles into solutions, and mark on the BOTTOM of the geletin container which one is which ("L" for lysol, "LA" for lysol apple scent...)....For clorox wipes, just punch out one of the wipes and use that. \n\n6. Wait for as long as it takes for a little clear ring to appear around the product's circle. The bigger the ring where there are no germs, the more effective the cleaning product. \n\nIMPORTANT: DON'T CLEAN YOUR TEST AREAS FOR A FEW WEEKS---otherwise the effects of the sanitizers won't be as strong.\n\nHope this helps!

You don't give us which lab you are doing, so results would be hard to find..  For general information, do a good web search with the name of what you distilled.  I don't think you will find everything you want, but there is a large number of websites on the general subject.

contact the company that made the test, they should have sample problems

Buy some, read the label, and call the company for the MSDS.  If there are nonhazardous ingredients, they will not be listed and you will have to get the company to tell you, search the patent literature, or have it tested ($5k-$25k for starters).

I did a science fair project that combined science and economics - it was called "Which Dish Washing Liquid is Best for Your Buck".  I tested which dish washing liquid was the best by seeing how many drops of it were needed to destroy the surface tension of a glass of water.  I then figured out how much each drop of dish washing liquid cost, and reported on the best value.  The judges seemed to like the economics side of it as well as the science fair side of it.  Good Luck!

Try "readyclean". It has always worked. But you must follow the instructions exactly. But beware some higher panel drug tests actually test for cleaners and things like that.

Pipettes are normally very accurate, but it depends on the brand. I use Fisher in my lab and they seem to be pretty good.\n\nYour best bet for the beaker is to completely ignore the markings. They are not standardized at all. Use a 100 mL graduated cylinder instead. They are much more accurate.

Assuming a pure substance, (this method will not work on mixtures).  \n1. Dissolve in Carbon disulphide.  (The compound is now banned in schools)\n2. Allow to evaporate in a fume cupboard.\n3. The presence of yellow rhombic like crystals is a test for S.\n4. Melt a sample and do a MP test.\n5. Melt a few grammes and allow to cool in air.  Needle like crystals will be formed.
