...factors of the stream determined how many fish and water invertebrates we found in the different areas. Introduction / Purpose The section of Kickapoo Creek we were at was located off of Loxa Rd. between Mattoon and Charleston. Group C was about a fourth of a mile down the creek. It was very hot (about 84-85 degrees) with a slight breeze. The stream was wide but shallow, and felt cool in the hot air. The stream was curved shaped and had no slope to it. It had a lot of leaves, twigs, and logs in the water. There were also some tires at the bottom of the creek in different places. Shaping the creek was a cliff sort of thing and at the top of it was a bean field. To get down to the stream we had to go down this windy path near the bridge. The stream had a bunch of schools of fish and other water creatures. In the stream there were fish, clams, rocks, sand, algae, bugs, invertebrates, and grass all over. The flow of the water was kind of a run/ripple in different areas. The purpose of going to the creek was to figure out the physical and chemical characteristics of the stream, to observe organisms present and their abundance, and to define the relative quality of a water ecosystem. Materials / Procedure Measuring Dissolved Oxygen: Materials needed for this experiment a dissolved oxygen kit. The test was done to measure the oxygen levels in the stream. It was done with a pole that has a cup at the end, so we couldn’t contaminate the water. Measuring Temperature: Materials needed a...

...Newsletter Lesson 1: Dissolved Oxygen Testing Water Quality Sampling Time Frame: Three 45-50 minute class Grade Level: 8th – 12th grade Overview: Dissolved Oxygen Dissolved oxygen is the form of oxygen in water that is freely available to aquatic plants and animals. Dissolved oxygen is vital to fish and other aquatic life and for the prevention of odors. Oxygen is transferred from the atmosphere into surface waters, as well as being produced by aquatic plants, algae and phytoplankton as a by-product of photosynthesis. Once dissolved in water, oxygen diffuses throughout a water body very slowly since distribution depends on the movement of aerated water by turbulence and currents, water flow and thermal upwelling. Traditionally, the level of dissolved oxygen has been accepted as the single most important indicator of a water body’s ability to support desirable aquatic life. The amount of oxygen required varies according to species and the stage of life of a species. Usually, dissolved oxygen levels of 5.0 to 6.0 part per million (ppm) are required for growth and activity. Dissolved oxygen levels below 3.0 ppm are stressful to most aquatic organisms. When levels fall below 2.0 ppm for an extended period of time, most fish will not survive. Oxygen is a particularly sensitive constituent because its availability during different times of day and times of year is influenced by temperature, other chemicals present in the water, and biological processes. Temperature plays a major...

...condition two, denoted B, we created a 10-3 concentration of algae. During the collecting of the brine shrimp, they had yet to hatch and we found it profoundly difficulty to collect individual cysts. Due to this, we estimated the number of cysts to be placed in each jar. We first diluted the sample of cysts we were given and collected a loop full and added it to each jar. In between each inoculation, we shook the plate containing the cysts and water to evenly distribute them. To estimate the number of cysts added to each jar, we then collected a loop full and counted the number...

...Longer containers with smaller openings such as the graduated cylinders and buret where wiped off by shoving paper towels down and rotating the glass while maintaining a hold on the towel. This method may have contributed to the percent error as this method could not wipe off every bit of liquid and there was some distilled water still at the bottom or near the bottom on the sides. The NaOH solution was prepared first by filling a graduated cylinder with 60.0 mL of distilled water. The solute was then gathered delicately by quickly unscrewing the jar containing the NaOH; removing a small portion of it via metal scoop and relocating it to a glass. Shortly after, the lid is screwed back on to the jar as leaving it exposed to air molecules or water for too long may cause the whole jar to dissociate. If the initial portion was not enough to fulfill the 1.20g requirement, the process of unscrewing and deftly collecting the NaOH as to not inflict harm to the original jar of NaOH can be repeated...

...When called to aid in collecting forensic evidence at a crime scene, forensic entomologists would bring all the necessary tools with them on the field. This includes basic equipment such as cameras, disposable gloves, and notebooks and pencils, to more advanced items such as specimen cups, pharmacy bottles, labels, nets, and dissecting forceps. Included in their array of gear is a “killing jar,” which is a glass jar containing ethyl acetate-soaked cotton balls. There are a number of procedures forensic entomologists must follow when it comes to collecting specimen. They must first collect any live flies using nets, then the largest maggots and egg mounds found on the remains. The bug experts preserve a few of the collected maggots by plunging them into boiling water then storing them in alcohol. This stops any chance of discoloration or decomposition of the maggots. Not only do forensic entomologist need to collect any insects seen with the naked eye, they also check ear canals, nasal openings, other orifices, and any open wounds for the presence of insects....

...Chapter 1 Covered in sweat I abruptly sit up in my bed panting. I realise had been dreaming, but do not seem to remember what the dream was about. I cast a glance at the mirror in my room. I notice a shimmering black figure with wings peering at me, it wears a top hat with a feather sticking out, and it kind of reminds me of Luis Carrol's mad hatter. I sit still in my bed, feeling strangely calm and protected. I have been collecting bugs since I was twelve, it is the only way I can stop their whispers. A pin will stop them pretty quick. Some of my victims line the walls of the house in shadow boxes. While others get sorted into mason jars, and placed on the bookshelves or for later use. Beetles, crickets, spiders... bees and butterflies. They do not die in vain, I use them for my art. I find it rather comforting, but dad objects, although he still lets me hang...

Reproductive Health. Gender Violence: Conclusion: Introduction: The Bay of Bengal, a northern and extended arm of the Indian Ocean and covering about 510,000 square km, is probably the "rebellious daughter" of the ocean who often turns too angry and smashes the lives of thousands along its huge coastlines particularly in the months of May and October each year. Actually, the coast of Bangladesh is known as a zone of multiple vulnerabilities. It is prone to severe natural disasters, such as cyclones, storm surges, and floods(The daily star, June 1, 2009). Aila of May 2009 is one of the most vulnerable disasters that causes hundreds of people’s death, massive damage of crops, domestic animals etc. Evan after two years of Aila, Aila affected people particularly women are in vulnerable situation. Their vulnerability are discussed in the below. Sources of data and methodology: The data for this study have been collected from the field Using qualitative...
