the science lab. In science‚ we would participate in a lab. One of my favorite labs was the owl pellet dissection. Owl pellets are owl throw up. In owl pellets you can find the bones of animals the owl consumed. In this lab we were to take out the bones we found in the pellet and construct the animal we found inside. Most people‚ like me‚ had a sort of rodent‚ but some people found birds in their pellet. Another one of my favorite things we did in science was the Sharpie tie dye lab in fifth grade

Asymmetric Epoxidation of Dihydronaphthalene with a Synthesized Jacobsen’s Catalyst Justin Lindsey 12/08/96 Chem 250 GG Professor Tim Hoyt TA: Andrea Egans Abstract. 1‚2 diaminocyclohexane was reacted with L-(+)-tartaric acid to yield (R‚R)-1‚2-diaminocyclohexane mono-(+)-tartrate salt. The tartrate salt was then reacted with potassium carbonate and 3‚5-di-tert-butylsalicylaldehyde to yield (R‚R)-N‚N’-Bis(3‚5-di-tert-butylsalicylidene)-1‚2-cyclohexanediamine‚ which was then reacted with Mn(OAc)2*4H2O

2013 Group No.: 8 Date Submitted: January 6‚ 2014 Experiment 4: Extraction and Chromatic Separation of Plant Pigments from Tomato Paste ABSTRACT In column chromatography a mixture is dissolved in a solvent and poured over a column of solid adsorbent then eluted with the same or a different solvent. This method is often used for preparative purposes; when a relatively large amount of the mixture and the components

behind. However it is inefficient because a small amount of liquid is always left in the solid residue and very fine solid particles take some time to settle out and any disturbance of the liquid can mix them in with the liquid being poured off. Chromatography is used to separate mixtures of substances into

experiment was to determine if green light had less ability to absorb than red light in spinach leaves. This was done by separating the photosynthetic pigments (chlorophyll a‚ chlorophyll b‚ carotene and xanthophylls) from one another using paper chromatography. The separated pigments were then analyzed for their absorption spectrum using a spectrographometer. When the data was graphed it clearly showed the higher rate of red light absorption over green light. These results along with previous research

separated by a procedure called chromatography. The procedure uses a special paper and solvent. The chlorophyll molecules adhere to the paper. The solvent molecules move up the paper by capillary action. Each chlorophyll molecule will travel up the paper at different rates. Hypothesis: If chlorophyll is removed from the plant‚ then the different pigments in the plant can be visible. Materials: -Spinach -Coin -Chromatography paper -Ruler

Candy Chromatography Background info: Paper chromatography is a logical technique used to separate works of a solution. Three examples of how we apply this technique to real-life would be: contaneminants in water‚ separation of plant pigmentation‚ and analysis of narcotics.
