Investigating if dissimilar sized candles have the capability of drinking equivalent quantity of water. Aim: The drinking candle science experiment is quite enthralling, as when performed, you'll observe a burning candle drinking up all the water kept beneath it due to the behaviour of the atmospheric pressure. The aim of this experiment is to investigate if unlike sized candles have the capability of drinking the same amount of water. Hypothesis: With all the information given on different…

The first step is to put on your goggles and apron. Then you need to gather your materials. You then need to make observation of the hydrate. Observe the color, state, texture, etc. to smell the unknown substance you need to waft the substance by slowly moving the smell of the liquid to your nose. Step 2- For the lab my group changed the way we were doing the experiment for time. This is the first way that we did it for trails one to two. First you need to get a beaker and mass it on a scale…

Caffeine is found in many products such as in pharmaceutical supplements, and beverages. Caffeine is mainly obtained from plant seeds or tea leaves. Extraction of caffeine is done to make decaffeinated coffee. There are three methods used to extract caffeine such as water extraction, supercritical carbon dioxide extraction and extraction by organic solvents. For this lab, the method used to extract caffeine will be by organic solvents. The purpose of the procedure is see how caffeine is isolated…

M & M Three oranges were cut in half and then placed over the juicer. The oranges were then pressed down, while being twisted allowing the juices from the oranges to be collected in the tray below. The orange juice in the trays were then poured into a 250ml beaker with cheese cloth on top of it. The cheesecloth caught the larger pieces of pulp from the oranges while allowing the juice to pass. The orange juice was then transferred into six 1.5ml centrifuge tubes. The six centrifuge were then…

CAUTION: It is best not to get dichloromethane on your skin. Gloves are to be worn during this experiment, if improper safety precautions are taken there is a possibility of irritation, and or burning of the skin. CAUTION: Gas will build up in the separatory funnel while you are shaking it, so you must vent the funnel occasionally to prevent the stopper from popping out, causing a mess and possibly getting dichloromethane on your skin. ~During the pre-phase of this experiment it is…

1)Hands were washed thoroughly with soap and water to ensure that no contamination on the coli-MUG tubes. The sealed plastic package was opened and coli-MUG tubes were removed. 2)Usually, inner fermentation vials contain only air. The assemblies was inverted and inner vials were allowed to fill with air, only if these inner vials contain any liquid. 3)Cap was removed and it was ensured that open end of the tube or the inside of the cap did not open. 4)Each of the given tubes were dispensed with…
