Also, while weighting the hanger and slotted, students have to record the measure and force, on when pulley pulling down the mass at the exact position over the radial. After getting the measure, remove the weight hanger. According to your lab instructor, all students should wear safety glasses because it applies torque to the shaft in the center pole to the mass going through radial fast with a revolution. Use the stopwatch to calculate the time while apparatus spinning 50 revolutions.
Here is how the zebra mussels destroyed and helped the river. Zebra mussels are small, bivalve mussels originally from the lakes and rivers located in Eastern Europe and in the western parts of Russia, which includes the Caspian Sea. Macalester.edu states that “they are filter feeders, pulling nutrients directly from the water.” They are about the size of your fingernail and can grow up to two inches long. They most likely came over to America “in the ballast water of ocean-going ships entering the Great Lakes.
The results of the tests were that the Susquehanna River is indeed, very good and healthy. It was discovered that temperature directly corresponds with dissolved oxygen. It was also discovered that there are different types of fish that live in different temperatures. Introduction
How to make a fishing pole out of house hold items and other thing that are related to fishing that will help. Minnow trap If you want to make a Minnow trap you will need a pop battle and a jug,then you will want to cut cut the bottom of the jug,after that you then need to cut the top of the pop bottle and put it in the bottom of the jug,next you will need to staple it in the bottom of the jug and throw it in the lake and catch Minnows. Fishing lure out of a spoon The most important thing you need for this is a common kitchen spoon,then cut the handle off the spoon until the round part then drill two holes at the top and bottom,next get a steel split rings and put them in the top and the bottom,after that get a treble hook and put it in
Group 1: Twenty five eyes for which a deep anterior lamellar keratoplasty was done using double bubble modification of the big bubble technique as described by Foroutan and Dastjerdi (2007). All cases were operated by a single experienced anterior segment surgeon. The recipient operative procedure was done first before stripping the descement membrane from the donor so as not to lose the graft if large DM perforation occurred and the surgeon decided to covert to PKP and it was done as follows: 1- Moxifloxacin HCl ophthalmic solution 0.5% was administrated for one to two days preoperatively, four times daily, to reduce the risk of infection.
The Effect of Exercise on the Cell Continuity of Betta Splendens Keerthana Arjuna Joe Gibson George Washington High School Abstract The objective of ted this experiment was to observe how exercise would affect the cell continuity of betta splendens’ muscle cells. To conduct this experiment, three fish were put under three different amounts of exercise for fourteen days. After fourteen days, the fish were euthanized and tissue samples were obtained. The tissue samples were stained with acid fuchsin.
“The the foil board is a surfboard with a hydrofoil that extends below below the board in the water”. Foilboards use a hydrofoil which is actually a piece from a boat. “A hydrofoil is a shaped vane (foil) that fits on to the bottom of a boat to increase the the boat’s
We used three squares of each of out five fabrics, our fabrics were cotton, linen, poly cotton, polyester, and nylon. Then you had to wash them in the washing machine for approximately thirty- eight minutes, with one fourth cup of Tide Simply fresh and Clean detergent, Then the materials dried over night, for the best results. The next day we put them in a sixteen ounce glass jar with the dye and two tablespoons of Dylon Tulip Red Permanent Fabric
Dissolved Oxygen is another thing we tested for, that 's how much oxygen gets mixed within the water ( Ex. rapids - the white part of the rapids is the oxygen mixing with the water- .) We also tested how fast the water was moving or the ( speed/velocity. ) We were going to test it by using a bamboo pole with a string ( with a certain length ) and a bobber on the end and see how long it takes for the bobber ( from its full length ) to hit the bamboo pole. To find the actual speed of the water you take the length of the string divided by the time ( sec/centi
Next, I removed the water and the quarter from the graduated cylinder and poured 50 mL of water again. I repeated this until I got results for all three coins. To find the volume of each coin, the formula I used was volume of water and coin - initial volume of water ( 50 mL ). To find the density, I divided the mass and the volume of each
The removal method group kept all of the crayfish collected aside to ensure only the new crayfish were collected. The 10-meter portion of the stream was then collected four more times, giving a total of five separate collections for each
Next one microliter of DNA was mixed with one microliter of loading dye using a pipettor and loaded into the well. The same mixing process was completed for the PCR product, using one microliter of PRC product and one microliter of loading dye. For the purposes of this experiment, the DNA product was loaded into well six and the PCR product was loaded into well seven. Initially DNA was loaded into well five, however gel was pierced so samples were moved one well to the right. The gel was run at 100 V for one hour.
