Discussing Surface Tension With Chemists

Discussing Surface Tension With ChemistsThere are a lot of different definitions of surface tension in Chemistry and there is no definite way to define it. It can be defined as the attraction between the liquids of different substances. This means that if you add water to gasoline, then the gas will be attracted to the water.In Chemistry, it is defined as 'the surface tension of two solids.' Solids are liquids and gases. The two types of solids are solid and liquid. The liquids that contain surface tension include water, ethylene glycol, and N2O.There are many different examples of these solids. Each type has a difference between their surface tension and other solids. Ethylene glycol is the best example of solids that contain surface tension. It attracts any other liquid that is about to touch the surface of the liquid. When you dip a can of N2O into the can, the substance will get attracted to the N2O and stay at the top of the can.There are many different forms of solids and some have more surface tension than others. So when you change one of them, you may have the same reaction as a second substance that has less surface tension. For example if you add water to gasoline, the surface tension of the gasoline will change and this could cause the pressure of the gas to increase or decrease. This is why it is important to know which type of substance is in contact with the surface of the gas or other substance before you try to make a chemical reaction.When you need to change the surface tension of a substance, you can do this by dipping it into a solvent. This solvent will give you a reaction mixture and will allow you to change the surface tension of the substance. If you want to change the surface tension of ethylene glycol, you can dip the substance into the solvent that contains naphthalene.You can also use diazinon, a solvent containing naphthalene. To do this you put the substance in a vial and freeze it. You then add naphthalene and let it go to react.T hese are just some of the ways that you can change the surface tension of a substance. There are many different methods and you should research this in depth to determine which one would work best for you. Whatever method you choose, always follow the instructions carefully so that you can avoid having problems down the road.

Online Vertex Formula Tutors

Online Vertex Formula Tutors A parabola depending upon the given equation opens either upward or downward. The vertex of a parabola is the point where the graph takes a turn and changes its direction. If a parabola opens upward, then the vertex of the parabola is the lowest point or the minimum point on the graph. If the parabola opens downward, then the vertex is the highest point or the maximum point on the graph. We can use the vertex formula in order to find the coordinates of the vertex of the parabola. Example 1: What is the vertex of the parabola of the equation y= 2x2 4x+ 5? The x coordinate of the vertex of a parabola is x = -b/2a for an equation of the form y= ax2+ bx+ c In the given question, a= 2, b= -4 and c= 5. Hence the vertex, x= - (-4)/ (2* 2) = 4/4= 1 Now substitute x= 1 in the given equation to get y. This gives: y= (2* 12) (4* 1) + 5= 2- 4+ 5= 3. Therefore the vertex of the parabola is= (1, 3). Example 2: What is the vertex of the parabola of the equation y= x2 + 6x + 8? The x coordinate of the vertex of a parabola is x = -b/2a for an equation of the form y= ax2+ bx+ c In the given question, a= 1, b= 6 and c= 8. Hence the vertex, x= - (6)/ (2* 1) = -6/2= -3. Now substitute x= -3 in the given equation to get y. This gives: y= (-32) + (6* -3) + 8= 9- 18 + 8= -1. Therefore the vertex of the parabola is= (-3, -1).

ADHD and Organization in the Classroom

ADHD and Organization in the Classroom When Im planning a classroom visit parents will often tell me that Ill have no problem figuring out which desk belongs to their child its the one overflowing with papers, books, pencils, and countless random items. Problems with organization can seem like they arent as impairing as other ADHD-related difficulties, like impulsivity or difficulty staying focused, but in fact, studies show that the kids with ADHD who struggle the most academically are those who have the greatest difficulty with organization. When children are disorganized, its harder for them to find their materials and get started right away, they have a harder time blocking out the visual clutter so they can stay on task, and their self-esteem can suffer if they are frequently criticized for their messy work area by parents and teachers and are teased by peers who label them as the messy student in the classroom. While it may appear that a disorganized child with ADHD is careless or sloppy, often these students care very much about their materials and wish they could have a neat desk like their classmates. The problem is that the executive functioning skills required for organization are underdeveloped, making it almost impossible for them to maintain an organized desk and work area on their own. For kids with ADHD, getting organized and staying organized requires structure and support from their teacher and repeated practice of organizational skills and strategies. Here is a simple 5 step process that will help the student get the support that they need: Do an initial desk clean out with the child. At a time when there are no other students in the classroom, do a complete desk clean out with the student. Everything should come out of the desk, and only the absolute minimum number of items should go back in. Fewer materials in the desk means there will be less to keep track of an organize on a day-to-day basis. Create an itemized checklist and tape it to the top of the desk. Make a checklist that includes every item the student needs to keep in the desk. The rule should be that if an item is not on the checklist, then it does not belong in the desk. If the student wants to put something in the desk that is not on the list, then he or she needs to ask permission and either update the list (if its a permanent addition) or take the item back home with at the end of the day so it doesnt create clutter. Schedule a daily desk check-in. At the end of each day, review the desk checklist with the student. Make sure only checklist items are in the desk and clear out any clutter that may have accumulated throughout the day. Over time you can have the student go through the checklist alone and call you over when he or she is ready for you to review his or her progress. Alternatively, if there is a kind, organized student in the classroom, you can have that student be a peer helper who is responsible for helping the student go through the checklist and clear out the clutter. Provide praise and rewards. Remember that keeping a desk organized is an extremely challenging task for many students with ADHD. Provide a lot of praise when you complete the daily check-ins, and when the desk is looking particularly neat, snap a picture to share with the students parents so the student can receive praise at home as well. Some kids may need to receive rewards as well to stay motivated. You can provide rewards either by adding a daily desk organization goal to his or her daily report card, or by providing small stickers or incentives at the end of each day. Review and update the desk checklist with the student monthly. As the curriculum changes throughout the year the student may need to add or remove items from the desk checklist. Review the checklist with the student and ask if there are items on the list that he or she is no longer using, or if there are things he or she needs regularly that arent in the desk or on the list. Actively engaging the student in this process will help him or her feel a sense of ownership over his or her organization and will help him or her develop valuable skills that he or she will be able to use independently in the future. While its unlikely that a child with ADHD will go from being highly disorganized to the neatest student in the classroom overnight, with a few supportive strategies and daily practice the student can keep his or her materials reasonably organized and will no longer stand out as having a desk thats the messiest one in the room.

The 6 Week Esperanto Challenge

The 6 Week Esperanto Challenge Last month,  Brendan from the USA  completed a 6 Week Esperanto Challenge! He made public posts about his progress to hold himself accountable for his weekly goals.   He agreed to write a guest post for us, from one successful Challenger to all the italki Language Challengers! When Brendan started, he was a total beginner.   After 6 weeks, in the final step of the Esperanto Challenge, he uploaded this 4-minute video of himself speaking Esperanto! Learning a language is not an easy task, even if its supposed to be an easy one like Esperanto. Starting in May, I participated in the Six Week Language Learning Challenge, and there was a special challenge with prizes to learn Esperanto. Since I had just begun my studies in Esperanto, and one of the organizers OKd me to be able to do it, I thought itd be great. Over the course of the challenge, I put in 40 hours (more or less) of hard work. I started with a beginners Esperanto course. I found out about Esperanto through reddit which led me to the ureddit course Esperanto 101. It had finished a couple months before I got there, so I contacted the teacher and she offered to correct quizzes and offer extra help. I went through her six lessons (ranging from thirty minutes to an hour) and it really gave me a solid foundation for the language. Esperanto Flag That, and a separate, unrelated course through Anki, also called Esperanto 101, were my main sources for learning the language. Anki is a flash card site (or app, as I used it) that uses a spaced repetition system to help you better learn the material. The deck I used had about 1000 cards with essential words. Besides Anki and the ureddit Esperanto 101 course, I used lang-8 for practicing grammar and the book Teach Yourself Esperanto. Teach Yourself Esperanto is a book course for learning Esperanto and though I only made it five or six chapters in, it was definitely the best tool for learning the language in my opinion. The content was thorough and the exercises were challenging. Those were my resources but my goals are what really pushed me along. At the start of each week Id set high standards for myself. I usually figured I wouldnt reach all my goals, but what was most important for me was setting how many hours I would study and reaching that goal if nothing else. Also, every single day I would complete a certain amount of Anki flash cards. I was not so great about reaching my other goals, but what really held me back was that I didnt have my goals somewhere I could easily look at them each day. That is really important. I started the challenge really strong then got a bit lazy. Dont ever allow yourself to get lazy because theres always enough time in the day to get a lot done. At the end of this challenge, I feel very confident and believe I made tremendous progress. I can understand plenty of Esperanto, and I think if I continue to work at it the rest of this summer, I could be very far along in the language. Good luck if youre learning Esperanto (I have really enjoyed learning it!) or any other language! I promise its worth it.
