LESSON 4: ELECTRICITY
Buzz, buzz, buzz. Atoms? Electrons?

Aurora was writing something on the whiteboard, which was something you would usually find in a modernistic muggle school, it was a lot easier then writing on a blackboard, Aurora could always find the capability to do things a lot easier when writing for a lesson on the whiteboard, then when she did in astronomy, which she had to use the blackboard. When she had finished doing what she needed to do get the lesson prepared visually, she began to write the rest of her lesson notes, so she could refer to them when she could, the subject they would be covering today was going to be hard to explain, as magic and electricity wasn't exactly the perfect combination. On the plus side, once this lesson was out of the way, things wouldn't be as complex, but this lesson had to come at some point and she would much rather they not have it on the last lesson of their first year in muggle studies. She had gotten everything ready and gotten each students folders/ring-binder's on their desks, dpending on which of the storage items they wanted to use, in which they were given the choice at the start of the year. She leant against her desk as she waited for the students to arrive, eventually they did, all trickling in, smiling at the regular stragglers, she turned back to the class and looked at the board.

"Welcome guys, today were going to be looking at something that muggles just can't seem to live without, electricity, now this was used all over my apartment in New York, in the television, in the lights, the stereo." Aurora pronounced. "Electricity itself cannot be used in the magical world as it interferes with magic, hence why we don't have electrical equipment to use freely. Today though we are going to do a quick overview to cover the basics on electricity." The professor stated towards the class in front of her. "Electricity is the flow of electrical power or charge. It is generated from conversion of another source of energy. Some ways of getting this conversion are to burn coal or natural gas. Nuclear reactions are another source of electricity along with water and batteries." Aurora lectured. "The basis of electricity is electrons, let's look at an atom in detail" Aurora stammered, she flipped over the white board revealing the master peice she had been working on to prepare for this lesson all year. "It took a while to make it exactly perfect, but I can't make it flawless" she grinned. The professor and the students looked up at the diagram of the atom and looked at it oddly, however the professor produced her notes and smiled again.

The Anatomy of an Atom

"This is an atom. These little dots are electrons." Professor Merrythought pointed out the black dots on the image. “Everything in the world contains atoms. There are both electrons, neutrons and protons within an atom. The electrons are negatively neutrons and the protons are positively charged. When there are more neutrons than protons within the atom, the atom has a negative charge. Neutrons are able to detach from their atoms within certain materials when they outnumber the protons. These neutrons are able to conduct electricity.” She said in a confused state, she was terrible at nuclear physics. “Materials that are able to conduct electricity include metals, where those materials that are not able to conduct electricity include wood and glass.” Aurora tapped the board again. “Muggles harness electricity and use it to power items within their home. Some of you used the refrigerator last week. The cooling ability is dependent on the use of electricity. Can anyone think of another item that you used that is dependent on electricity?” Professor Merrythought listened to the answer given before moving on.

“Great answers. I will admit that you can become very dependent on the use of electricity. One problem with moving back and forth from the magical world to the muggle world is that electricity does not work in the magical world. Electricity has what I can only call a bad reaction around the use of magic. As some of you may have noticed, I have been using my wand on the board today. In a muggle classroom, I would be using a computer and a program called powerpoint to project the images you see on the board today. Computers do not work within the walls of the castle. Powerpoint is a program for the computer that would allow me to place images on the wall or a screen and flip through them with ease for you.” Aurora looked at her students and realized this was probably not the most exciting lesson for them. “Okay. That is it for today. I know that this is not the most exciting thing to learn about, so I will just leave you with one last thought for the day. Electricity can be deadly. When you are in the muggle world, avoid allowing electricity to pass through your body. Use caution. If you are unsure of how to work with an electrical item, ask someone how to use it. Electricity when used wrong has been known to cause death.” She smiled. “That’s it. See you all next week.”
Homework Assignment
For your homework, just role play the lesson and take notes, as usual. Please post an answer to the question posed. You will be responsible for the information for the exam, so take good note their folks!

Ella walked into the muggle studies classroom and took her usual seat. Since she grew up in the muggle world, this class hadn't been too difficult, and she managed to good grades on her assignments. But, something was off this week.... and by looking around at the students, she could tell it wasn't with them. Where is Professor Weiss?! Ella thought as she looked up to where Professor Weiss used to stand in front of the board. Is Professor Merrythought teaching muggle studies now? Or is she just subbing in? Ella attempted to hide her befuddled expression by smiling and pulling out her notebook and pen.

Electricity wasn't new information to Ella, as she had grown up with it, but she had never actually mastered the science behind it. In fact, she found atoms, protons, and the like rather confusing. Although she was not much of an artist, Ella tried to draw the picture that was on the board and copied copious amounts of notes on the subject. I will ace this exam!

During the field trip, Ella recalled listening to an old CD. The CD player and headphones that she used definitely needed electricity to function. Ella raised her hand and waited until she was called on before speaking, "The music player that I discovered last week is an object that relies on electricity to function." Ella did not have to copy as many notes during the remainder of the class, and quickly packed up her things and left when she was dismissed.

Professor Patricia Styx

History of Magic Professor: Yrs 1 -4 | Former Puff & Head Girl: Class of 2027 | Ex-St Mungo's Healer

This week was already turning out better for the Hufflepuff teen than last week. Her boring routine had been changed by receiving some exciting news from her brother Joseph. The fact it was coming from her older brother was surprising enough, as it was normally her mother who wrote to her, but what the letter contained was far more exciting and slightly shocking. He was getting married! Patricia had to re-read the letter a few times to make sure she was reading it right. But no matter how many times she read the letter it kept confirming what she already knew; Joseph was getting married and was going to be a father. The idea of becoming an aunt was very exciting to Patricia. She had met Nataliia a few times and loved her; she was so nice and had an amazing dress sense, Patricia was happy for the two of them, even though she and Joseph didn't always see eye to eye.

Fully recovered from her cold, but still a bit disgruntled from missing the latest Quidditch match she was back to her morning run, shower, breakfast and class. Even though she was damning this boring routine last week she was much more cheerful as she was getting daily updates from home about the weeding, it was going to be soon, very soon, Patricia knew she would have to visit Headmistress Rambolt soon to ask permission to leave the grounds for the wedding, it was something she wouldn't want to miss. And after one of the most recent letters she figured it might not be too hard to get said permission as she would have two professors also attending the wedding. She was rather horrified when she received the letter a breakfast one morning updating her of the guest list, a few names, apart from usual family members, jumped out at her. One, which she didn't mind, was her boss – Elliot Keaton, seemingly a good friend of Nataliia. But two expect, Isolde Glasson and Kalif Styx! Seemingly Chris had invited Professor Glasson as his date, Patricia wasn't even aware they knew each other. And Professor Styx was Nataliia's brother, well half-brother, Patricia wouldn't end up related to him would she? She hoped not.

Trying to get that certain letter out of her head she entered the Muggle Studies classroom. Patricia was still a bit worn down with the cold, so she was once again glad that she had the chance to wear her own clothes which kept her warmer than a skirt, even with tights. Entering the classroom she had to check the door again. Yep it was definitely Muggle Studies, so why was Professor Merrythought there. Maybe Professor Weiss was sick last week and took a few days off to recover. Patricia shrugged and made her way to her seat, it wouldn’t be the first time a teacher had to sub.

Once the rest of the class had entered Patricia turned her attention to Professor Merrythought and wondered how she would fair as a Muggle Studies Professor, she was a great Astronomy one. Patricia listened to Professor Merrythought make a great start to the lesson, she was probably working off Professor Weiss’ notes but there was something about it that made it Professor Merrythought’s lesson and not Professor Weiss’s. Patricia took out her pen and paper and as she took down her notes she realised how well Christopher would ace this class. He was such a science wiz, well being a Science teacher would do that she thought to herself as she listened to Professor Merrythought.

The Atom!
  • Electrons are inside an atom

Patricia was quite enjoying this lesson, it was like a science lesson back home, but then again this particular part of science had never been her strong point, thankfully she had Christopher to help her when need be. When Professor Merrythought asked what else is dependant on electricity Patricia raised her hand and said, An iron. it was a silly answer but one of the first that came to her mind. After she finished writing down her notes, she heard Professor Merrythought say that was all and see you all next week? Was Professor Merrythought taking over Muggle Studies? Or was Professor Weiss just taking an extra week? Who was going to teach Astronomy now? Patricia left the class with a headache, with all the extra information and the questions in her head right now; she needed to lie down, and soon!
