Safety and the Environment 2. Data Collection and Processing2.1. Data Collection Qualitative data: As the beetroot cylinders were each placed into the different temperature water baths, the colour of the beetroots started to dissolve into the water, i.e. colouring it. The beetroot cylinders in the warmer water baths clearly coloured the water more than the ones in the lower temperature baths, this can be seen in the big difference of absorbance between 8 °C and 85 °C water samples.
6 grams of dried seaweed, cut into ½ inches should be places into a 150 mL beakers that will later be filled with ¾ distilled or deionized water. Then, the seaweed should be agitated with a stirring rod to remove monosodium glutamate. 2. After the water is poured off in the sink, 40 mL of distilled water should be added to the seaweed, and should be heated for 5 minutes with a Bunsen burner. 3.
Procedure: 1. Fill a beaker two-thirds full of water and add approximately 20 drops of IKI. Write down the solution's color and record the mass of the bag. 2. Do an initial Benedict's test on the 15% glucose/1% starch and the beaker solutions for glucose by putting some of the solution and a roughly equal amount of blue Benedict's solution in a test tube, placing the test tube in boiling water for 90 seconds, and observing whether or not the solution changes color from blue.
The third step is to clean the knife using the napkin and wipe it clean. The knife is sharp so be extra careful when cleaning it to avoid injury. The fourth step is to get the jar of Jelly and the knife. Open the jar of jelly. Use the knife to scoop out a small amount of jelly from the jar.
3. I then measured out 750ml of tap water and added it to the pot where my cabbage was. 4. I then started boiling the cabbage while I assembled the 7 different substances including the coke and antacid as per the special instructions for this lab. 5.

Investigation into the effect of variation in temperature on the permeability of cell membranes using fresh beetroot. Identification of trends and patterns As the temperature was raised, more pigment leaked out of the beetroot disks, which in turn meant that less light was able to be transmitted through the liquid. For example, at 80°c the percentage light transmission through the liquid was 0%. At 20°c the percentage light transmission through the liquid was 76%. This proving the above statement.
Using the measuring cup, add two cup of confectioner’s sugar into the pitcher as well. If you have doubt about how sweet you like your Kool-Aid, start with one cup of sugar and add more as needed, tasting with each addition. Now, with your long-handled spoon submersed in the pitcher of water, carefully stir until all of the Kool-Aid powder dissolves. Then, with your spoon filled with Kool-Aid, do a final taste

Experiment 2 Time | Observations | 5 minutes | Bubbled like sugar | Once salt water was added | Turned soapy white and thick | Equation: METHOD 1) Put 2 cm3 of castor oil into a 250 cm3 beaker and add 10 cm3 of 5mol.dm-3 sodium hydroxide from a measuring cylinder. (Take care when measuring this out and adding it to the beaker to avoid any drips and spills.) 2) Heat the mixture gently over a tripod and gauze, STIRRING CONSTANTLY with a glass rod (otherwise the mixture erupts). Allow to simmer (boil gently) for 5 minutes. Steady the beaker using
