The data graphed include six or seven locations from each of the three Portland Schools. The School district tested nearly 00 buildings. Is there enough data here to make any conclusions about the water in Portland schools? What about for schools A, B and C? I believe that these graphs are enough to make a conclusion about Portland schools. For example, in the test it states, “But even low levels are not safe-just safer.” On the graphs of the schools A, B and C, every fountain contains a level of lead. 45% of the fountains contain more lead than the EPA’s action limit. This is already unsafe. Also, the pipes between the schools are most likely connected and made out of the same lead material.
2. Each school had its water tested by a different

They may have different methods and ways of testing that water. Also, school A shows that it has more lead than schools B and C. Maybe the lab that tested school A had a more precise test.
3. Based on the data presented in the graphs, how do you think each school should respond to the results of the testing? Should students drink the water in the school? Explain your answer. These schools each have at least one fountain that was over the EPA’s action limit. They could replace the pipes. However this could be expensive.. They should take away at the fountains so the kids don’t keep drinking the schools water. Even though the fountains with less leas are safer, over time more and more lead will damage the kids bodies (as it explained in the article).
4. If the water was tested again at each fountain, might the results be different? Explain your answer. The results of the second could be much different than the first test. For example, in the text it explains how when water sits in the pipes for a long period of time, it gets more lead in it. As a result of this the tests would be different because the water could have sat in the pipes over summer or the schools could have continued to use the fountains the same amount of time, so there would be the same amount of
... water crisis will have a long term affect on those who are consuming this water on a daily basis. Lead attack the brain and can cause coma and possibly death. Children who survive lead poisoning are left with serious health issues such as metal defects and leave a child mentally unstable. Even at lower levels of exposure symptoms such as behavioural changes such as reduced attention span, reduced intelligence quotient (IQ). Children with smaller amount of lead exposure also showed increased anti social behaviour, it also reduces educational attainment. These side effect of high lead exposure can leave children scarred for life. The water crisis in Flint Michigan car scar children for life. This could all be resolved if they could come to an agreement and replace the water pipes, allowing for cleaner and healthier water to be accessible to citizens in Flint Michigan.
5. A second test tube was then filled with water and placed in a test
This is why the Flint water crisis is so critical today. Because young children are being exposed to lead and they should actually be screened from the lead. The pipelines with lead in the water system and the whole community of Flint, not being able to drink water out of the facet as well as not being able to
Two public notification clauses exist in the LCR. First is the Lead Consumer Notice, according to 40 CFR 141.86(g), lead testing results must be sent to consumers of the water supply within 30 days regardless of whether the AL was exceeded. Second is the Consumer Confidence Report, 40 CFR 141.154 sta...
They are concerned that their kids are getting too much lead in the bloodstream because they have been drinking the tap water.
The case study titled "School Officials from Marshall Metro High School Attempt to Motivate Students & Teachers to Achieve Higher Performance" is about the different ways the school system used to motivate the students to come to school (Kinicki & Williams, 2013, p.405). It is also a good example of how rewards and behavior can affect the outcome of the situation.
Evaluation: If this experiment was to be redone then more diverse oceanic life would have to be used playing different roles in the water. The experiment performed showed a small projection of the ocean’s course if pH levels rise but by adding more confounding variables then maybe the outcome may have been different. If another researcher is to replicate this experiment it is optimal if they did several different trials to see if the same result occurs like the one just performed.
I personally did the nitrate test, but there were many more tests that our group did that day. There is the nitrate test, the phosphate test, the alkalinity ppm test, the ph paper test, and our leader collected rocks to test if they can neutralize acids because that means it can resist acidity. Nitrates and phosphates are polyatomic ions that when they go into streams, they will cause overpopulation of algae and mess up the ecosystem. Dissolved oxygen is good and bad for the creek, if there is too much will kill the macroinvertebrates and too little will to. Acid rain is really bad in our area and because of that we had to test the pH of the creek. pH goes on a scale of 0-14, 0 is a very acidic reading and 14 is a very alkaline reading. Things that have a lot of alkalinity will neutralize the acid make it go to 7, which is the default reading and the reading for average water. A lot of our readings are measured in ppm, or parts per
The hypothesis for this experiment was, If three different types of waters (saltwater, fresh water, tap water) are tested, then the liquids won’t evaporate at the same rate and tap water will evaporate at the fastest rate because it won’t have any non-volatile substances to hold it back from evaporating.
If the three water sources are tested for chemical contaminants, then tap water will have the highest concentration and Dasani water the lowest concentration of contaminants

The organization I work for is a nursing home management company. That’s the simple definition. Health Services Management Group manages of the operations of eleven (11) skilled nursing facilities (SNF), and three (3) home health agencies (HHA). Each of the SNFs and HHAs are operated/licensed by a single purpose entity. Of these long term care providers, one (1) SNF and two (2) HHAs are operated as non-profit organizations. The purpose of the non-profit providers, ultimately, is to fund The Trousdale School. “Trousdale School serves high functioning adults with intellectual disabilities, providing academics and life skills for the purpose of learning independence.” 1
As the test tubes were taken out of the water bath and placed the in
I understand that eighty years ago, kids were shorter. It makes perfect sense, less food, and not too many bovine growth hormones. In fact, it was probably considered sensible to build shorter water fountains. But why would you not feel the need to replace those water fountains years later when they only come up to kid’s knees? Hydration is a fundamental part of life. I suggest three ways to improve the drinking conditions of all students at Worland High school. To build new water fountains Worland students need to do three things, raise water awareness, earn money for new water fountains, and convince teachers to support the cause.
The 14th of December 2013(Saturday) was the day when this fieldtrip was organised .it was a pleasant day, our whole class of grade 10 evm students (25 students) got ready and we head out for wazirabad Delhi. We had decided to go to three places and collect water samples so that we could conduct different tests on samples such as:
