First, set up the natural indoor light station and the artificial light station (also known as dark station). Hang the 20 Watt Fluorescent Bulb from the ceiling 35 to 40 centimeters above the artificial light station. For the indoor light station set up the flat surface by a window that will get natural light during the day. Next, lay out and count 12 Sweet Corn Seeds and 12 Pea Seeds. Lay these on a paper towel to make sure they do not get any other oils or acids on them that could affect the experiment. Afterwards, take a metric ruler and measure each seed in millimeters to figure out the average length of the Sweet Corn and Pea Seeds. To find the average length of each seed add up all the measurements and divide them by the number of seeds measured, in the experiment divide by 12. Now, take 12 Ziploc Quart-sized bags and label them accordingly using a marker or Sharpie: include the type of seed, the solution that the paper towel will be soaked with, the pH of the solution (which will be determined later), and whether it will be in the artificial light station or indoor light station (also known as dark station). After, prepare approximately 5 ounces of Shoppers Value Distilled White Vinegar (4% Acidity) and approximately 8 ounces of Tap Water. Test the pH of each liquid …show more content…
To make the water solution simply take 4 ounces of tap water that has a pH of 5. To make the vinegar solution simply take 4 ounces of Shoppers Value Distilled White Vinegar (4% Acidity) that has a pH of 3. Finally, to make the water-vinegar mixture take approximately 4 ounces of water and about 1 mL of vinegar to make a mixture that contains a pH of 4. It may take a couple tries to find the pH the experiment requires. After making solutions that match the given pH keep each in a bowl to be later poured into plastic bags. Do not forget to include the pH reading on the Ziploc
Each subsequent trial will use one gram more. 2.Put baking soda into reaction vessel. 3.Measure 40 mL vinegar. 4.Completely fill 1000 mL graduated cylinder with water.
...ost likely to be battery acid. If it is water, it has a Ph level of around 7. For vinegar, the Ph level is approximately 2.4 - 3.4. Thus, once testing the liquid compare it with the Ph levels above to discover the mystery solution.
2. Drop a gummy bear into each of your prepared beaker or cup and place the beaker or cup
1. Put 400 mL of tap water into a beaker. Heat it on a hot plate until it starts to boil.
The materials my group used were three identical plastic cups, four gummy bears of the same color, one plastic spoon, one roll wax paper, one sharpie marker, one roll plastic wrap, one graduated cylinder, 25 mL super saturated salt solution, 25 mL distilled water, 25 mL 80% sugar solution, and one 12 inch ruler. The procedure my group made follows these steps.
While completing this lab we used four liquids. We used water, milk, orange juice, and soda. To hold the liquids we used two q-tips. We used two petri dishes, one was to hold the pill bugs while they were not being used in the
Each Biology 108 section planted these pots and the data from every section was to be combined for an overall data sheet. Our group in section 6 had the role of planting 5 of the experimental pots with the assigned number of wheat seeds or mustard seeds or both.
the effect light has on the growth of pea plants. It will take place in an environment with controlled light, with equal amounts of plants being grown in the light and in the dark. All elements of the experiment other than light will be kept the same, such as amount of seeds in each pot, amount of soil in each pot and amount of water given to each plant each day. This will ensure a fair experiment. Prediction: I predict that in general, the plants grown in the light will grow better than those grown in the dark.
Plan 1. Collect 4 different sized beakers 2. Boil some water in the kettle 3. Pour 50ml into each beaker 4. After 1 minute check temperature 5.
Put a label on each test tube. With a pencil, number each test tube from one to twelve.
...l of distilled water, blend for 2 minutes on high speed until mixture is smooth with no lumps (measure the weight of the cabbage using the scale).
We used wheatgrass were 40 wheatgrass seeds, two empty pots, soil, and water. We first added soil for both pots and 20 wheatgrass seeds in each pot. My partner and I decided that we label pot one experiment which is “sugar and water” and pot two control which is “water” only. The experiment was for almost four weeks we had to make sure both get the same room temperature and water, so we can see the results after this amount of time. Both pots had same room temperature so both can have the same amount of sunlight also, the same amount of water which is a glass of water from the sink once a week. In the experiment pot we added a glass of water with one teaspoon of sugar and the control pot glass of water. Every week we used to see both pots grow almost the same. At the end of the experiment, my partner and I measured the length for both plants and we recorded the average for each plant, so we can know the rate of growth
I am going to use a range of concentrations to enable me to get a good
3.) Divide your 30g of white substance into the 4 test tubes evenly. You should put 7.5g into each test tube along with the water.
* Size of potatoes * Diameter of each potato tube * Time in sugar solution We need to make sure in both experiments the fair test lists are used and the procedures are carried out. This needs to be done otherwise my results will not be accurate and will look odd. Method: Firstly we got out all our equipment.
