We first labeled each cup with what type of water we were going to use. We put an equal amount of soil into each cup. Our next step was to put exactly 20 seeds into each cup approximately ¼ inch deep. After that we poured 20ml of each type of water into its designated cup. After the grass started to sprout we measured its growth in centimeters and then gave each cup its 20ml of water.
After 10 min, add the potatoes. Let 10 more minutes pass then add the corn-on-the-cob. After 10 more minutes, add the crab meat. 2 minutes later, add the shrimp. Cook for 4 more minutes, then drain liquid from pot and pour contents over a clean, unused large garbage bag or newspapers.
Water the seeds daily until the grass is at least 1.5 inches tall. Take 20 seeds from a rapid growing weed plant and evenly plant 10 in each box. Water the grass regularly until weeds start to grow throughout the grass. Follow directions for each weed killer and apply is to the boxes of grass/weeds. Make sure to use the same amount of weed killer in each box.
Basing our hypothesis off of this past experiment, I hypothesized that in the presence of ammonium nitrate we should see an increased germination rate of our spores from the Ceratopteris richardii. We grew 2 different cultures of the fern spores, one on a control petri dish and one in 1% NH4NO3, with 6 replicates. They were grown for 4 weeks and were put under sufficient lighting. All the data was compiled from all the replicates and after all the calculations we found that there was a significant difference in the spore germination rate. Less germinated in the presence of 1% ammonium nitrate compared to the spores not in the presence of ammonium nitrate.
2.pour 2 cups of sugar in sauce pan and stir.the solution should look cloudy at first then i will become clear .then keep stirring for 2 minutes 3.After the sugar is dissolved pour the solution into the jar. 4.seed one stick by covering it in sugar.set the non seeded stick aside 5.insert the seeded stick into the center of the lid and cover all holes. 6complete steps 1-4 and insert non seeded stick. For best results let it sit for a week or more (seeded) Observations Day 1(sugar solution made) During the first 2 hours tiny crystals started to form Day 2 The sugar is starting to form Day 3 The crystals are a little bigger the day before Day 4 On the fourth day there is an increase of the amount of
Hypothesis: Corresponding to the theory of composting, it is more than possible that a cup filled with organic matter, leaves, water, and soil will be decomposed from at the end of a fourteen-day period, producing and organic mixture rich in nutrients, that will help the nourishment of my garden, and small orchard in my mom's backyard. • Plastic Cup • Scissors • Plastic wrap • Camera • thermometer • Notebook • Vegetable scraps • Fruit scraps • Egg shell • Soil • Grass clippings • Leaves • Water Procedure: Made holes on the bottom of the plastic cup with a scissors, and placed of the organic matter on a bowl and mixed with a plastic spoon. At the end, I made a little hole on the plastic wrap and introduced the thermometer on the middle of the cup. Experiment: • I placed the plastic cup on my kitchen window where direct sunlight and shade is accessible to prevent extreme temperatures. This composting lab.
Materials & Methods Materials: · Scale · 4 6” Dialysis Tubing · 4 Transfer Pipets · Sugar · Scissors · Rubber Bands · 4 Same-Sized Coffee Cups · 250ml Graduated Cylinder · Tape Measure · Sauce Pan · 3 600ml Containers · Plastic Covering · Spoon Methods: 1.) Place 4 6” pieces of dialysis tubing into coffee cups full of tap with and leave them for two hours prior to beginning the experiment. 2.) As you wait, prepare your three sugar solutions. For the first solution, pour 5 grams of sugar into 250ml graduated cylinder and add water up to the 250ml mark.
We let them soak for 20 minutes than we removed them from the test tubes. Next we measured their new weights and recorded them. They were; 10% NaCl decreased by 4%, 15% NaCl decreased by 8%, and 20% NaCl decreased by 12.5%.The results showed us the conclusion that the potatoes were hypertonic to the deionized water and were hypotonic to the sodium chloride solutions. Introduction: The objective of this experiment is to detect diffusion and osmosis in potato cells in 3 solutions. Diffusion is the spontaneous spread of molecules from an area of high concentration to an area of low concentration.
To grow the E. coli, 190ml of 2% glucose nutrient media was added to a 250nl Erlenmeyer flask. 10ml of nutrient media was used to blank the spectrophotometer set at OD600. 10ml of E. coli stock culture were added to the 190ml nutrient media, creating a 1:20 dilution. The inoculated nutrient media was then placed into a 37C orbital shatter to incubate. All solutions measured with the spectrophotometer were placed in spectrophotometer tubes.
To determine if hyphae grow at the same rate, graph the results of table 2 and compare the slopes of the 3 hyphae from the slide preparations. 11. To determine if mycalolide B affects fungal tip growth and nuclear position repeat all the steps except in step 2 need to add mycalolide B and let it incubate for 10 minutes. Make sure to label the slides with the
