Supplies Sink w/ running water Liquid soap Trash can Hand lotion Disposable paper towels Assessment (Data Collection) Step 1 Action Determine length of time needed for handwashing according to task at hand or degree of spoilage. Rationale The longer the washing‚ the more microorganisms are removed Planning Step 2 Action Check that the soap and towels are at hand before beginning. Rationale Saves time Step 3 Action Crank out towels from dispenser so they are ready to tear off

Candy Chromatography: What makes those colors? The point of doing this project is to use paper chromatography to see which dyes are used in the coatings of your favorite colored candies. Chromatography is a technique for separating mixtures. Chromatography can be used to separate specific components from a complex mixture‚ based on molecular size or other chemical properties. It can also be used to identify chemicals‚ for example crime scene samples like blood‚ drugs‚ or explosive residue. Highly

prevalence of the green chlorophyll. Anothocyanin(red or purple)‚ carotene(orange)‚ and xanthrophyll(yellow) are found in different proportions in different leaves. Leaf pigments can be separated by using paper chromatography. Paper chromatography is a technique that extracts pigments into a paper filter called chromatogram. What are the pigments are in Red Wondering Jews? Carotenoids These pigments primarily absorb in the blue wavelengths‚ allowing the longer wavelengths to be scattered and producing

AND PARACETAMOLPRACTICAL REPORT ON THE ISOLATION AND IDENTIFICATION OF CODEINE AND PARACETAMOL AIM: To extract codeine and paracetamol from its tablet by solvent extraction and tentatively identify in comparison to standards using Thin Layer Chromatography. INTRODUCTION: Codeine or methyl morphine‚ an alkaloid‚ was first isolated in 1832 from raw opium. It concentration ranges from 0.2% to 0.8%. Mostly used for its analgesic‚ anti-tussive and anti-diarrheal capabilities (Tremlett‚ Anderson

Chromatography Experiment of the Drosophila Eye Pigmentation Pathway Introduction: How can the use of chromatography help explain single gene mutations of the drosophila melanogaster bio-synthetic pigment pathway? This experiment was meant to help connect the mode of inheritance with different eye color mutations and pinpoint where they occur in the pigment pathway. The drosophila eye color is a result of two bio-synthetic eye color pathways‚ this is expressed as a trait or phenotype‚ a multigene
