Things You Learn As a Summer Camp Counselor
Things You Learn As a Summer Camp Counselor Image via. https://pixabay.com/en/sailing-lake-summer-camp-kids-2655756/ Humility: Working at the Bottom of the Food Chain One major lesson that you will learn from being a camp counselor is humility and understanding what itâs like to start at the bottom of the career food chain. When you go into an internship or even an entry-level position, you wonât have tons of power and you will, most likely, be asked to do things (like coffee runs) that seem to be way below your pay grade. Itâs so important to understand that you have to work your way up in the work world, and working as a camp counselor shows you that. As a camp counselor, you will be dealing with younger kids, moody parents, and making sure that no one ever gets hurt. You may be thinking that this is silly and that kids and parents should just ~mellow out~, but they canât and they wonât. Dealing with issues of this nature will make going on the coffee runs and printing out notes for a meeting so much easier and fun. Attention to Detail: Mistakes Cannot be Made when Working with Kids Working with kids, of any age, is not an easy feat. You have to ensure that they are safe at all times because they are under your care and supervision. Because of this, you will learn great attention to detail. If you are in charge of lunch time, snack time, medications, injuries, etc. you have to be extremely attentive of detail. You cannot make mistakes when working with kids. You have to be so careful of everything that the kids doâ"what they eat, what they say, their opinions about camp, etc. Therefore, from an early age, you will learn not to make mistakes in your future office job. It may not be a matter of life and death in the office, but your time at summer camp will prevent you from making mistakes and, therefore, you will look like a star employee to your superiors. Other employees who were never camp counselors might accidentally add Splenda to their bossâ coffee, but not you! Interacting with Kids: You May Want to Start a Family Some Day I love children, but this is not true for many people my age. Working at a summer camp may make you fall in love with children! Okay, this is probably overly optimistic, but it will teach you how to interact with kids and how to keep them safe without overstepping your boundaries as a camp counselor. Camp counseling jobs can help you land babysitting jobs (you can talk to various parents at carpool), aka you fill up your wallet with some more cash. Eventually, these babysitting jobs will help you learn about taking care of children in a more personalized setting, which is what you would be doing somewhat once you start a family (obviously still a very different vibe, but you know what Iâm saying). I am in no way saying to start a family right now, Iâm just saying that working as a camp counselor will teach you how to look after kids and how to find a nice combination of fun and discipline. Image via. https://pixabay.com/en/adventure-backpack-the-bag-scouts-1807495/ I promise you that working at summer camp is super fun and there are tons of different options as to what type of camp you could work out. You can do indoor, outdoor, full day, half day, athletic, artistic, multi-faceted, etc. You may not get paid that most amazing salary, but itâs a great way to learn a strong work ethic and learn the value of a dollar when you are in high school and in your early years of college. So, donât just stand there, start thinking about your plans for the rest of the summer and your plans for next summer so that you can experience all of the wonderful things that come with being a summer camp counselor! Happy summer and, to all of my fellow camp counselors, God bless you and good luck!

5 physical activities for kids adverse to sports - TutorNerds
5 physical activities for kids adverse to sports - TutorNerds After school activities: 5 physical activities for kids adverse to sports Its important for kids to get exercise on a regular basis even during the cold winter months. Traditionally, students would participate in an after school sport sponsored by the school or local community. Although these are great opportunities for many students, some kids are just not that into organized sports and end up on the sidelines without a chance to socialize or exercise. Fortunately, there are tons of physical activities out there for kids who dont like sports. 1. Swimming lessons Swimming lessons are great for younger kids because it gives them a chance to learn valuable coordination and water safety skills while also allowing them to get out all of their extra energy. Of course, kids cant just jump into the pool without knowing basic safety skills that they learn from a private instructor but, once they have those skills, they have a great alternative to playing on an organized team. Swimmers can work on their stroke at their pace, and either swims at an outdoor or indoor pool depending on the time of year. Swimming is also a relaxing form of exercise that can help kids and teens manage their stress. 2. Yoga for kids Many fitness centers and studios now have yoga classes made just for kids and families. This is also a great alternative to playing on sports teams because it is a great way to relax and de-stress as kids start to progress through middle and high school and has all of those difficult exams to focus on. Yoga can be adjusted to all fitness and skill levels and is something that can be done indoors during these cold winter months (READ: Time Management: The Key to Success in Middle School). 3. Indoor gym workout Indoor gym workouts are getting more popular these days because most communities have at least one family-oriented gym or fitness center available to kids and teens. This is another great way for kids to work on their physical fitness in a climate controlled environment during the winter. Many gyms offer classes where students can pick and choose which type of physical activity they want to work on. Additionally, most gyms are open extended hours so kids wont have to worry about squeezing in their work out around their homework and study schedule. 4. Run club A lot of young students would love to be on the track and field team but just cant make the time commitment taking into consideration all the homework they have to complete. An excellent alternative is to join a community based running club where athletes can join in two or three days a week or as often as their school schedule allows. Students who feel theyâre missing out on a little bit of competition will find opportunities to enter team races and shoot for a personal best or a prize in their age category. 5. Dance Dance lessons also provide an excellent physical fitness opportunity and combine that with creativity. Students who are interested in the arts and music may find that dance is the right exercise for them because it allows them to express themselves artistically while practicing a healthy exercise routine and making new friends. In short Whether kids play on an official school team or exercise outside of school; physical fitness is a major part of a well-rounded education. Also, students to exercise on a regular basis will have an easier time concentrating during extended homework sessions and younger kids will find it easier to behave if they dont have a ton of extra energy in the classroom.

Their honest opinions should shed some light on whether the course would appeal to you.Another way to gauge whether an acting class would suit you is to find out more about the content of the course. Does the course concentrate on acting for TV and film roles, for example, or is it more geared towards preparing you for roles in the theatre?

The Yorkshire Academy of Film and Television Acting, on the other hand, offers 90-minute, 60-minute, and drop-in classes.So, when deciding on an acting course, there are several factors to keep in mind when deciding which class will give you the most value for your money.As a general rule of thumb, if you consider the following issues before booking your first class, you should be able to decide on a course thatâs right for you:Is the course well-regarded;Are the tutors qualified?;Can I afford the classes?;Do the classes cover the topics I want to learn more about?;Can these classes make me a better actor?; andWould I be better off havin g private or one on one tutoring?And remember, if you are struggling to find a drama class thatâs right for you, or you want to spend extra time outside of class developing your acting talents, you can also consider using a private tutor such as an acting tutor from Superprof to help you fine-tune your abilities as an actor.Find more acting classes in the UK:Acting classes in the UKActing classes in LondonActing classes in ManchesterActing classes in GlasgowActing classes in BirminghamActing classes in EdinburghActing classes in BelfastActing classes in Cardiff

Everything You Ever Needed to Know about Reflection and Refraction.
Everything You Ever Needed to Know about Reflection and Refraction. What are Reflection and Refraction? ChaptersReflection All Starts with Waves.So, What is Reflection?What is Refraction?Honestly, it is quite special that you can look into a mirror and see reflected in the glass an image of you. It is so incredibly clear â" depending on the quality of the mirror, obviously â" with all our features and details so well defined.Of course, although we are one of the few animals on this planet of ours that can actually recognise ourselves in that reflected image in a mirror, we take this thing a little for granted.Thinking of all this, have you seen the famous images of Eilean Donan, the castle in the Scottish Highlands? Usually, it is photographed from across a loch â" as, from here, you can see the castle doubled in the surface of the water.Have you ever shouted down a long tunnel and heard your voice return a hundred times? Have you ever had an x-ray? Have you ever seen a rainbow?The point of all this is that reflection is something that is happening all around us at all times. Even a s you are looking at this screen, you are probably seeing a faint silhouette reflecting back at you.But what is reflection? Do you know? What makes that image of yourself return to you from the mirror? Or how come you can see Eilean Donan both on land and in the water?Itâs quite a simple scientific phenomenon, really â" but, given that there is quite a bit to learn, it is what we are going to talk about here.So, letâs get ready and dive in. Reflection all begins with the science of waves.Find a math and physics tutor here. When a surface reflects like a mirror, the reflection is known as 'specular''.

But what are waves?Waves are disturbances or variations in space-time which, through their propagation, transmit energy from one point to another â " or indeed from one point to many others. This energy travels in straight lines from the waveâs source and disturbs the medium through which it travels as it travels.No doubt youâll have seen diagrams of waves in your science classes. Usually you see images of transversal waves, the waves that produce ripples, peaks and troughs, disturbances of the medium that are perpendicular to the direction of the energyâs travel. Yet, there are longitudinal waves too, in which the disturbance is parallel to the travel of energy.Depending on the type of wave â" longitudinal or transverse, mechanical or electromagnetic â" and its wavelength (essentially the size of the wave), different waves can travel through different media. So, transverse waves, such as the movement of a guitar string, can only travel through solids. Meanwhile, sound waves â" which are longitudinal â" can travel through solids, liquids, and gases.Electromagnetic Waves.It is important to note that electromagnetic wa ves are transversal too. However, these guys are in a different ball game.Because they donât actually need a material medium through which to propagate â" as they create a magnetic field that allows them to âself-propagateâ. Thus, they can travel through a vacuum.As we said, however, depending on their wavelengths, they may not be able to travel through some solids or gases. Think about it. You can listen to your radio in your bedroom â" and radio waves are electromagnetic â" however light waves (also electromagnetic) cannot travel through walls.The wavelength of light is much smaller than the wavelength of radio waves. And this is the key to their fate: absorption, reflection, or transmission.Find out about the properties of waves!So, What is Reflection?Letâs turn to reflection now. Do you know a good definition of reflection?Reflection is the change in direction of a wave on meeting an interface between two different media â" so that it returns into the medium from whi ch it came.If light, travelling through air, hits a reflective surface, it will bounce back. However, this change in direction cannot occur apart from at a surface â" an interface â" between two materials.The Case of Light.Light is usually the type of wave that is discussed in relation to reflection â" if only because, as outlined above, it is one of the types of reflection that we see so often.But light doesnât reflect off every single surface, does it? When you look at a brick wall, it doesnât reflect. Nor if you look at a transparent pane of glass. This is because the type of material that a light wave encounters will determine the effect of made upon the wave of light.Light, when it encounters an interface, will follow four different paths:Transmission â" When light passes through a material, such as a transparent material. This includes, refraction, when light passes into a different medium through which it slows down.Absorption â" When the light passes into a differen t medium which absorbs its energy â" and transforms it into a different kind of energy (such as thermal energy).Specular reflection â" When light is reflected in such a way that it produces a mirror-like effect. Light here is reflected from a smooth surface at a definite angle.Diffuse reflection â" When light is reflected from a rough surface and its waves are scattered. In these cases, the mirror-like image is lost.Whilst specular reflection is what we conventionally understand to be reflection, actually all surfaces that donât absorb light reflect it. Your skin, the computer keyboard, houses and animals â" literally everything that you can see reflects light. Otherwise, you wouldnât be able to see it. The distortion of the image is all to do with refractionThe Law of Reflection.One of the most important things to learn when you are studying the reflection of light is the so-called law of reflection.Simply put, the law of reflection states that the angle of incidence equals the angle of reflection. To translate these two terms, this means that the angle from which the wave strikes the interface will be equalled by the angle at which the reflection of light bounces back.If you draw a line at ninety degrees (a right angle) from the reflective surface â" a line which we call the ânormalâ â" the angles of incidence and reflection are measured between the incident wave and that normal.So, if light enters at forty-five degrees, it will reflect at forty-five degrees too.By the way, this only applies to surfaces that are âsmoothâ.What Makes a Surface Reflective?You know a reflective surface when you see it. It is sort of shiny, again smooth, and you can see your face in it.Yet, t his doesnât really explain why that surface is shiny. Nor does it tell us what it is in that surface that is shiny.The thing that determines the reflective potential of a surface is not really fully explained by a reference to âsmoothnessâ. Because, as we know, waves are absolutely tiny â" so a surface that is visibly smooth may well not be at a level appropriate to light waves.Electrons.Rather, the reflectiveness of materials and their surfaces is all about electrons. These subatomic particles vibrate at different frequencies depending on the material.But light waves have differing frequencies too. âLightâ as we know it is a selection of a whole load of different frequencies and wavelengths.When a particular light wave encounters a material whose electrons have the same vibrational frequency, this light wave is absorbed into this vibrational energy. However, when the frequency of the electronsâ vibration is not equal to the frequency of the light waves, the light is re flected.Remember that every surface you see is reflective. Yet, the different light waves responsible for each colour have different frequencies. This means that some light waves might be absorbed by some materials, whilst others are reflected â" giving you different colour materials.Find out all about sound waves! You see refraction in rainbows too!What is Refraction?Do you remember that one of the things that happens to light as it reaches an interface is known as transmission? This is what happens when the wave just keeps on going.However, with light, this is only possible with transparent glass â" and the clearest of water.When a medium is not completely transparent â" or if the medium is quite large â" the transmission can still happen. However, the light wave will slow down and, as a result, it will change direction. This is the process known as refraction.One of the most common examples of refraction is that of the glass prism. These triangular objects have an effect on light that means that the waves scatter into the colours of the rainbow. This is because of the different wavelengths of the different light waves responsible for each colour. They all slow down at their own rate.
