The Categorization of Chemicals As Safe Or Dangerous

The Categorization of Chemicals As Safe Or DangerousWhen talking about the chemical and biological toxicity of pesticides, chemicals and any chemical for that matter, the chemical classification is often referred to as cis or trans. The cis label refers to the chemical class that is composed of substances that are naturally occurring and therefore can be said to be 'safe' to be used, while the trans classification refers to a chemical class that is created by man and is deemed unsafe to be used.The cis classification refers to substances that are produced by plants and animals and found in their natural environment. These substances are toxic to humans and can cause diseases, allergies and cancer. Common examples of the cis classifications are arsenic, bromine, chlorine, dioxins, lead, mercury, nickel, nitrates, pesticides, herbicides, vinyls, solvents, and others.In contrast, the trans classification refers to substances that are created by man and are found in man-made sources. Exa mples of the trans classifications are industrial chemicals, prescription drugs, prescription drugs that were taken by humans in large quantities, a small number of compounds within an industrial plant, pharmaceutical drugs, herbicides, fungicides, herbicides that are the synthetic variety, preservatives, many prescription medications, some antidepressants, and certain types of drugs. These are substances that pose little risk to human health because they are not naturally occurring and therefore the only risk is that the humans ingesting them might suffer from adverse reactions.One of the important features of the cis classification is that humans can metabolize these chemicals to a degree in their bodies. Many scientists believe that since the toxic effects of a chemical compound are determined by how it is metabolized and eliminated, that chemicals which are classified as cis are safer than those which are classified as trans. This is especially true for toxic chemical mixtures, as the amount of a substance that can be eliminated or metabolized is limited.There are numerous reasons why a chemical is classified as cis. For example, if a chemical is classified as cis, then the likelihood of a large percentage of humans consuming it will limit its potential harm to the individual's health and also limit the impact of the resultant damage on the environment as well.In addition, the cis classification refers to the class of chemical that is as safe as it can possibly be and the trans classification refers to the class of chemical that is considered to be a carcinogen, a cancer causing agent. The role of cis chemicals in relation to toxic chemical mixtures is so significant that several organizations have banned or are currently considering banning the use of chemicals such as polychlorinated biphenyls (PCBs), and dye and other toxic chemical mixtures. This in turn has led to a need for more research to be conducted.It is important to note that while the cis clas sification is more desirable than the trans classification, the truth is that many chemicals are in the cis classification, such as organophosphates, which are a group of insecticides and pesticides commonly used to control pests. While they are considered 'safe' for humans to consume, they are thought to be harmful to children and for animals, in which case they are usually classified as trans.

Classroom Management Homework Help Strategies

Classroom Management Homework Help Strategies Classroom Management Strategies for Every Teacher People become teachers because they care about children and their futures and because they are passionate about helping students achieve their potential. However, teaching is a not an easy joband one of the most challenging aspects for many teachers is figuring out how to effectively manage the classroom. If you ever have trouble keeping your students on task or have been thrown off course by troublesome students, you may need ideas to better manage your classroom and redirect the focus to student learning. Here are a number of battle-tested strategies that teachers can put to work in any classroom, as shared in David Adamsons Classroom Management: 24 Strategies Every Teacher Needs to Know: Use social cues One of the best ways to communicate with students about appropriate behavior is to state a desired behavior that you want to see in class. Attribute the behavior to a specific student and affirm the behavior as a great example for the other students. What to say: Thanks to table 3 for having their eyes on me. I see that John has started working on the assignment; thank you, John. Establish time limits Plan out your day carefully, which will help you keep your students engaged. Share your expectations of time limits and schedule. What to say: Ill give you about five minutes for this task. Everyone needs to be in their seats in 30 seconds, please. Manage your transitions Transitions from task to task can be challenging and time consuming, with students getting distracted or misbehaving. However, if you plan for transitions and explain carefully what you want students to do and how much time they have to do it, you can minimize that wandering or waiting time. What to do: Be prepared, get students attention, explain what you want students to do, confirm their understanding, give a signal to begin, give a time limit and start the next activity. Show respect The classroom environment cannot be productive without respectbetween you and your students and among the students themselves. You cannot demand respect; however, you can exhibit respectful behavior toward students, thereby influencing how they respond to you. What to do: Be polite, avoid sarcasm, be on time and ready to teach and maintain a dignified student environment. Keep a brisk pace Students today are used to fast-paced interaction. You can minimize behavioral problems by picking up the pace of a lesson, introducing interesting activities and having extra activities on hand to fill gaps of time. What to do: Plan ahead, pose questions that invite critical thinking, and try different mediums for reinforcement of lessons. Intervene in the moment When needed, give simple reminders to bring unfocused or disruptive students back on task. What to do: Communicate nonverbally with a look or facial expression, change your tone of voice or move closer to the misbehaving student. Teaching is an important and rewarding career with many wonderful aspects to it, but it certainly has its challenges as well. Managing classroom behavior and expectations is an essential part of the job that allows you to maintain control of your classroom and keep the focus on learning.

An Open Letter to the Woman Who Tried to Pee On My Car

An Open Letter to the Woman Who Tried to Pee On My Car Photo by Romi34 via Flickr I am not mad at you. I am mad at myself. I am mad for not seeing the artistry with which you flicked up your khaki skirt in one fluid motion. A motion practiced and executed with the precision and ease of Tiger Woods golf swing. Underneath your skirt were black men’s briefs, your whitey tighties transcending color and logic. You bent down, arched your back, and stuck out your chest. You pressed your pumpkin butt-cheeks against my door handle like a kiss. You paused, hands on knees. There was a moment. A moment that holds so much beauty and significance, that the only appropriate action is to be silent. To try and absorb what you can, though you know you’ll never be able to fully appreciate or understand it. And what I did nextâ€"what I did to that momentâ€"I will regret for the rest of my life. I reached over and pounded my fist against my passenger window. Hey, I shouted, Hey! She turned around and stared at me, and I stared back. Those eyes. You were about to paint the Mona Lisa before me, but I panicked. I panicked the way men panic when confronted with power they can’t understand. All too often, invitations get lost in the mail, and fear knocks on your door when appreciation was meant to. I’m sorry, she said. She pulled her skirt back down as best she could, and took a step forward. I’m so sorry, she said as she turned her head around a final time, taking those eyes with her. No, I am sorry. I don’t know what you had in mind. I don’t deserve to know. I’d like to think you would have doused the flames of conformity with a hearty stream of Gatorade and string-cheese infused pee. I’d like to think you would have lifted the societal veil of deception from my eyes the way you lifted your skirt over those confusingly bumpy hips. I’d like to think you would have not only urinated on my car, but on my heart. If you return to me, I will take your hand. We will waddle our way to Washington, march up the steps of the Lincoln memorial, climb up on Abe’s shoulders, and pee on his face. But you won’t. You’re gone and not coming back. I sent you away, like so many before me. A bathroom? Why? A toilet? Says who? I’m not mad at you. I’m mad at myself.

Irvine SAT Tutoring Tips A Timeline to the New SAT in June

Irvine SAT Tutoring Tips A Timeline to the New SAT in June Tips From an Irvine Private SAT Tutor: A Timeline to the New SAT in June Students have had a week or so to relax after AP exams. However, students who have opted to take the new SAT on June 4th need to make sure they are ready for that important exam. Although juniors will have another opportunity to take the SAT in the fall, its much easier to simply get this test out of the way and achieve a good score the first time around. Of course, this is easier said than done but students can do a few things to prepare for the SAT between now and the June 4th testing date. Hopefully, students will have been working with a study group or tutor to make sure they understand the differences between the old exam and the new version. Regardless of how much studying a student has already completed it’s smart to review before the exam and follow the time-tested test prep strategy between now and the day of the exam. 1. Review the test booklet and online study materials Whether a student is working on a test booklet or focusing solely on online study materials, its important that they review what theyve been doing in the last few weeks. Students should also go through their personal notes as well as work with their tutor to identify any topics or skills that are still giving them trouble. Review is an important part of preparing for the SAT exam especially if students have stopped their study to have prepared for the AP exams back in mid-May. Math formulas and editing skills should be fresh in students’ minds when they enter the classroom on testing day (READ: Last Minute SAT Study Guide). 2. Schedule a review sessions with an Irvine SAT tutor If students havent worked with their tutor for a while, itd be a good idea to schedule a couple of review sessions. Most tutors keep notes regarding what each of their students excels in as well as what their weaknesses might be. With all of this studying occurring in the spring, students themselves may have forgotten skills that need to be developed. However, a few hours with a tutor can usually rectify this issue in no time. 3. Work on any weak areas Every student possesses strengths and weaknesses. Some students excel in math but struggle with grammar while others have an eye for punctuation but may have difficulty reading a chart or graph. Hopefully, students have identified which areas they struggle in over the last several weeks. Now is their last chance (for the June testing date, anyways) to improve. If students have yet to determine their specific weaknesses, they are strongly encouraged to take a practice exam or answer practice questions offered by the College Board to help troubleshoot (READ: 5 Awesome SAT Apps). 4. Dont forget to review strong areas While focusing on areas of improvement, many students simply forget to study stronger areas. This can lead to a lot of frustration when students have an answer right on the tip of their tongue but cant quite remember it. This is often because a student forgot to go over subjects they excel in. If a student hasn’t reviewed their stronger areas in a few weeks, it’s a good idea to do this now. 5. Work on concentration Students are also encouraged to work on their focus and concentration since they will be sitting in a testing room for several hours. Most people, students or working adults, struggle to sit down and focus on one activity for several hours at a time without taking a substantial break. The short breaks students get during the SAT are only long enough to allow them to stretch and have a sip of water. Its a great idea to work on this concentration by taking a practice exam in its entirety. This way students will know what to expect the day of the test.

Rethinking education common misconceptions about teachers

Rethinking education common misconceptions about teachers Our new blog series, ‘rethinking education’, explores common misconceptions about learning and new ways that international teachers can imagine their classrooms while teaching overseas in order to make the most enriching educational experience for students. When it comes to teachers and teaching, everyone has an opinion - what makes a good teacher, what makes a bad teacher, how to teach - the list goes on. Read below as we explore some of the biggest misconceptions we’ve heard and why they’re misconceptions. Teachers teach because they can’t do How often have you heard the statement, “those who can’t do, teach?” This one is easy to debunk because teachers do so much that it’s hard to believe this statement ever came to be. On top of the deep knowledge teachers need of their subject matter in order to excite and engage their students day-to-day, teachers spend a lot of time developing a number of skills, classroom management methods, and pedagogical approaches in order to foster their students’ growth and progress. Teachers are no different than other careers in that they need a certain set of competencies to succeed. Teachers have it easy It’s easy to see why this misconception has surfaced: because bubbling under the surface of this one are several other misconceptions! Many think that teachers finish their workday at 3 pm and have their summers off. This just isn’t true. Teachers actually have one of the most emotionally intensive jobs out there, because they engage in the lives of 20+ students every day. They worry about their academic achievement, their home lives, their friends and social lives, and their self esteem. Aside from all that they invest in their students emotionally, teachers also dedicate a lot of time to their craft. The 8 am - 3 pm schedule is a myth, and teachers often have to participate in school-wide activities like curriculum development, personal learning in order to prep for lesson plans, marking and grading, parent-teacher engagement and interaction, and after school activities. Good teachers mean good grades Sometimes parents and outsiders mistakenly believe that teachers are the only ones responsible for a students’ learning process. This is another misconception that needs to be be debunked. Teachers are one important part of the equation, but certainly not the be all, end all. Students’ parents are also an integral part of a students’ learning process, and should encourage their children to engage in and be curious about different subject matter. Students themselves are also one of the biggest parts of the equation -- if a student comes unprepared to engage in the classroom material, the teacher has held up their end of the contract but the student remains closed off to learning. There are ways that you as a teacher can try to break down a student’s walls if they appear uninterested in your lesson plans. Firstly, try to speak one on one with this student to learn where their interests lie and how you can interest them in classroom material. Secondly, give your students the opportunities to share with you what’s important to them by developing interactive lesson plans. This is especially important in international classrooms where your students may come from different backgrounds and might have varied experiences.

Are There Any Good Reasons to Use Snhu Tutoring?

Are There Any Good Reasons to Use Snhu Tutoring?The topic of snhu tutoring is highly popular with teachers and students alike. It has helped many people learn to speak a foreign language quickly and easily. However, it can be dangerous to teach it to untrained and unsupervised students as well.Snhu tutoring has been in use for centuries and there are good reasons for this. First of all, it teaches people how to read, write, and speak a foreign language. Another thing that she tutoring does is, it changes the way a person thinks about a foreign language.A person who learns a foreign language starts to understand and take it less seriously. They start to enjoy the language more and have a more positive attitude about it. This type of snow tutoring has been very effective in the past, but if you use it too much, your students will not be able to focus on their studies properly and they will actually lose interest in the language.Language tutors have also been found to be just as effecti ve as a regular teacher. But this doesn't mean that every language tutor is equal. There are people out there who do the best work possible and they are more likely to make the most of the money you give them and to help people to become more fluent in their own native tongue.Tutoring students can get them to take their studies more seriously and they will learn better. When they speak the language, they will be talking about it more actively and might be able to distinguish words that don't even exist in their own languages. Language tutors and language learning teachers are in great demand all over the world, but it's worth doing it the right way and having them do it well.The main problem with snhu tutoring is that it takes a long time. The tutor cannot work full time and he has to be available for one to two hours a day to supervise each student. Many countries only have one language instructor per class, so if you have a large school system, this is probably not the best option for you.If you want to give a language tutor a chance, you should ensure that you choose a tutor who works independently of you. Get your own personal assistant and you will have more time for yourself.
