The Battle of Hogwarts Group: Erica Brooks, Courtney Keeler, Jamie Pate Physical Science 5 th Period 11/17/10
electrical energy The night was dark and treacherous. Rain fell like needles of ice, and slivers of electrical energy bolted across the sky as lightning. Luckily, the young witches and wizards at Hogwarts were inside and eating dinner, safe within the warmth of the castle…
A young boy burst into the hall, racked with shivers and soaked to the bone. Harry recognized him as one of the boys standing guard at the front gates. “Death- Eaters!” the boy spluttered. “Three of them! We’re under attack!”
potential energy kinetic energy On another day, perhaps one in the bright, colorful warmth of autumn, there would have been at least a modicum of hesitation. In the frosty tension of a shadowy December night, however, everyone was eager to take the boy at his word. Teachers and students alike leaped into action, losing their potential energy as it turned into the kinetic energy movement brought on.
mechanical energy radiant energy thermal energy The majority of the fighters headed towards the Main Hall, but Harry was sure the Death- Eaters would be in Gryffindor Tower looking for him. Along with Ron and Hermione, he bolted upstairs using mechanical energy to do so. Along the way, each grabbed a torch (radiant energy often acted up around magic, unlike thermal energy, so they used torches instead of light bulbs.
Their suspicions proved correct— three Death- Eaters who had previously been sifting through the tower’s contents jumped as the trio entered, wands raised. One of them, Harry noticed briefly, immediately separated from the others and attempted to jump out the window, where their wands were presumably waiting.
Dodging, Harry shouted to Ron to raise the alarm in the Great Hall. There was no time to protest. Harry was somewhat relieved to see him go. Though Ron’s absence robbed them of a numerical advantage, now there was a lesser chance of Ron being hurt. nuclear energy The other two, unfortunately, were not so cowardly. They wasted no time hurling death curses— really a magical form of concentrated nuclear energy— towards the three young wizards
chemical energy The next few moments were a blur of jinxes and hexes, each changing colors when their caster chose to add a little chemical energy. There were no more death curses, Harry was relieved to see, though he knew they probably needed him alive for some horrible reason. Law of Conservation of Energy Though magic was hardly physically demanding, Harry felt himself tiring— magic, after all, was just concentrated energy, and due to the Law of Conservation of Energy, it had to come from somewhere– in this case, his life-energy.
The older wizards, however, did not tire so easily. After so many moments, Harry and Hermione were fairly on the ground. It seemed all hope was lost…
Then a tidal wave of wizards of every race, gender, and age poured into the tower. Ron had sent for help! As the Death-Eaters retreated through the windows and their peers shot at them from the window, Harry and Hermione nearly collapsed in relief. The day had been saved, and no one had been hurt.FIN
