and Weed control experts. Hypothesis If home-made and commercial herbicides are sprayed on weeds then the commercial herbicides will be more effective, because the chemicals are made by experts who know what chemicals kill and prevent weeds. Experiment Fill 2 different boxes and fill then with soil make sure to use the same type and amount of soil. Measure around one cup of grass seed and sprinkle it on the soil. Water the seeds daily until the grass is at least 1.5 inches tall.
Adequate separation will have occurred when the cresol red dye front has moved at least 50 mm from the wells. Gel may be stained either with 1 µg/ml ethidium bromide for 10 minutes or 0.05% methylene blue (or proprietary) stain for 30 minutes, followed by 20-30 minutes destaining with water. * If adding Bromophenol Blue loading dye to sample: do not add the loading dye to the entire sample, leave 10µl of sample without loading dye if you will be sending sample in for
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.
When the roots are good and thick and the stem has leaved out, your avocado is ready for potting. Use a terracotta pot with a top diameter of about 10 inches. Put broken crockery around the drainage hole in the bottom of the pot and fill with soil rich in humus, leaving enough space for the seed and roots. Place the seed gently on top of the soil, taking care not to injure the roots. Carefully add soil until the seed is half covered, but do not tamp it down.
To get mass of food burnt, I subtracted the initial mass by the final mass. I then repeated these steps for the other two samples making sure to clean and dry the beaker each time. I got the heat energy gained by multiplying the ΔT by the mass of the water and 4.184 J/g°C. Then I calculated the heat energy per unit mass by taking my heat energy gained and dividing it by the mass of food burnt to get Joules/ g. To get the Cal of the sample I took the J/g and divided it by 4.184 and then divided that answer by 1,000 to get my Calorie. Observations: Marshmallow: I noticed that the marshmallow caught fire pretty quick.
After shredding was complete the pile of cabbage was placed into a stainless steel cook pot. 2. In order to attempt to get the most accurate results I used my fish tank ph test to identify the ph level of my tap water. The result was my tap water is about a 7.8 (slightly higher than the 7.0 that is considered neutral). 3.
In June of 2000 the cap requirements were changed from a multi-media cap to a geosynthetic clay cap. OU2’s elements were ground water removal via on-site extraction wells, ground water treatment (air stripping) for removal of VOC’s, discharge to a local water treatment plant and continued monitoring. In 2005 an amended report eliminated the removal and treatment part and, instead, replaced it with an injection of vegetable oil as a bioremediation of the VOC’s with monitoring. OU’3 excavation and stabilization of contaminated soils, on-site disposal of the stabilized soil, installation of a low permeability cap over the treated soil, placement of one foot of topsoil over the remainder of the uncapped site and placement of controls. The clean up approach for OU4 was to allow the clean up of the other operable units to address the contamination of the wetlands.
• Use soap to wash hands after working with potassium iodide. • Never expose Schoenbein paper to direct sunlight. Testing Procedure • If Schoenbein strips have been freshly made, they are ready for immediate
The cap of a centrifuge tube was used to collect approximately one (1) gram of soil from the sample. This was then added to a bottle containing 99ml of sterile water for a 10-2 dilution, 1ml of 10-2 dilution was then added to a bottle containing 99ml of water for a 10-4 dilution. 1ml from the 10-4 dilution was then added to 99ml of water for a final dilution of 10-6. 1ul of each was plated on different starch agar plates with the aid of a micropipette and a plate spreader. The plates were then incubated for a week.
If we water too little this could lead to the seed drying out Because if the plants are not watered everyday the seeds would dry out and not germinate but if it’s watered too often then the seed would drown in the water and not germinate Amount of solution watered to By using a measuring beans (12ml) cylinder to measure the solution. Day of watering plant By remembering to come to (everyday for 3 days straight) class everyday for 3 days straight. Area where petri dish
