The variable I am going to change will be the temperature Essay Example for Free

The variable I am going to change will be the temperature Essay The aim of my experiment is to investigate how the resistance of a wire is Affected by the length of the wire. I will be investigating by using three types of wire Thin, Thick and finally an even thicker wire then second time around. I will be also recording my results by taking down what the volt meter displays and what the Ammeter displays. I will be recording the results for each wire and also I will be increasing the wires thickness after I measure 10cm of length each time having taken down the results. Apparatus: Meter Ruler- Safety Goggles- Cell- Wire- Crocodile Clips- Ammeter- A Voltmeter- V Plan For the following experiment my plan will be to firstly wire up all the appliances to create a circuit then I will predict whether the resistance increases or whether it does not increase while the wire increases. I will carry out the experiment increasing the length of the wire by 10cm each time I will then take down the results of the voltage, current. To measure the voltage I will use a Voltmeter to measure the Voltage, to measure the length of the wire I will use a meter ruler and finally to measure the current I will use a Amp meter. After gaining these results I will work out the resistance using this formula: Resistance=Voltage/Current Having gaining the results I will write them up in a table from which I will plot the graph to support my results Then after drawing the graphs I will come to my conclusion, in my conclusion I will conclude what happened in the experiment and I will say whether my prediction is right. I will then come on to the evaluation of my experiment. Prediction My prediction is as the Length of the wire increase by 10cm the resistance will get affected making it to increase. The factors which may affect my experiment are firstly the cell(Battery) which may ran out or cause a defect, The voltmeter or ammeter may show the wrong Voltage or current and there also could be a wrong connection being made connecting the circuits. There also could be a user fault and they may measure the wrong length of wire. The factors which need to be controlled are to firstly to get a good working battery and them some healthy working wires. You need to make sure u connect the circuit correctly and also you need to make sure you measure the correct length each time. I will also keep the same temperature to make sure the experiment is even I will do this by using a thermometer to make sure the temperature is constant. I will be using Room temperature. Work Done By- SaNjE Balendra Table of results (Thin Wire) Length Voltage Current Resistance Here is the table of results for my second experiment in which I used a thick wire Table of results (2nd Thicker Wire) Length Voltage Current Resistance Here is the table of results for third and final experiment Work Done By- SaNjE Balendra Conclusion Having done my experiment I have come to my conclusion. In my experiment I have found out that as the length of the wire increases the resistance increases. This is because as the length of the wire increases it causes the current and voltage to increase which means the resistance increases as well resistance is equal to voltage divided by current. The resistance increases because there is more sufficient surface area which means the can atoms to collide, when the thickness increases it causes the resistance to decrease as there is a lot of surface area so there will be less collision. Evaluation The experiment proved to be a success and it went very well although it could be improved by trying other lengths, different voltages but also a different type of wire to be able to compare the resistance difference this would make a more interesting experiment. I feel overall my results were quite precise. You can see my results were accurate looking at all 3 of my graphs, which shows a straight line through most of the points apart from one or two which are on the line or not very apart from the line. The 2 points on the (thin wire) which was not close to the line was a Anomaly but it did not effect the gradient in the graph. In my experiment the places I think I made the most errors in the experiment was measuring the length of the wire as it was hard to measure the wire keeping it straight and then holding a meter wire to measure it. I can improve on how to measure the wire by using more than one person to either help me or do the experiment with me, I can also improve by being sensible and being focused on my work and on what am doing.

Puberty Blues Essay

The TV show I have chosen to talk to you about today is Puberty Blues. It is aired at 8:30pm, Wednesday on channel 10. It doesn’t have a specific genre, but more like a mixture. I would classify it as a teen drama. Puberty Blues doesnt work in plot twists but offers a suprising reality. The best part about the TV drama for me is how we get a glimpse into the life of a 1970’s teenager. Puberty Blues is set in Cronulla, Sydney, in the late 1970’s. Majority of the time, Debbie and Sue’s houses are used, but the ‘greenhill gang’ are also featured hanging around by the beach. Puberty Blues tells the story Debbie Vickers and Sue Knights. They are both very clever but somewhat unpopular high school girls who wants to raise their social standings in order to go out with boys. Through out the episodes we get to know the girls’ parents- Judy and Martin who are closed off and don’t interact with each other much and Pam and Roger who have a far more open relationship. The sixth episode was directed by Glendyn Ivin and written by Fiona Seresis. The main plot is when the ‘greenhill gang’ including Debbie and Sue, get wasted, go driving and flip the car, killing the driver. Any other show would have sent the characters into an instant panic but the writers of Puberty Blues understand that the shock combined with drugs would have caused everyone to burst into disbelieving laughter. The car crash wasn’t the only plot in the episode though. Debbies parents, Judy and Martin, got to couples councilling because Martin has strong feelings for a women at his work. Cheryl, a member of the ‘green hills’ gang, is flirting with her mum’s boyfriend to prove she is more desirable than her mother, who resents. The social issue pressented in the show was definitely driving under the influence. This message is easily interpreted in the car crash scene were the driver and passengers are drunk and stoned. This wasn’t my favourite episode from Puberty Blues but it was still solid like we have come to expect from this series. I would recommend the show to high school students and older as there are some mature themes and sexual references. I love this show because it takes awkward and serious situations and brings out their bright side.

The Ancient Roman Way of Life Essay - 1205 Words

The Roman way of life is different and similar to modern day. Though one may not know much over the Roman’s the culture is fascinating and still remembered in history. The clothes, food, customs, and leisure are major in Roman lifestyle. During the ancient Roman time period, clothing was crucial in citizens’ status of either emperor, wealthy, middle class, poor, or slave. The emperor would have worn the toga trabea, which was, â€Å"formal differences in togas which denoted social rank† (Roman Dress). The emperor himself would wear a toga with a purple stripe to show his status. As emperor, he would also wear the latus clavus, tunica palmata, and the toga palmata.

During Ancient Rome, â€Å"Romans waited until the main meal of the day, the cena, (Tingay and Marks 38) to truly eat. The cena came in three courses, the appetizers, the main course, and the secundae mensae. When the food was served, it came with plenty of wine. This was because Romans had two hundred varieties or more from all over the empire. In the cena, â€Å"Food was served on dishes. Most were made of glass or pottery, but if the family was very rich there would also be ornate platters of gold and silver (Tingay and Marks 39). The Romans had spoons and knives but they preferred eating with their hands and fingers. As the slaves brought the food out on various dishes they would also pour the wine from the amphorae into a jug for easy pouring during meals. At many of the meals the host would normally have three couches, the summus, medius, and imus. (Top, middle, bottom). â€Å"The diners were seated according to their social status† (Tingay and Marks 39). When the guest arrived at the host’s house for the dinner party there woul d be couches surrounding the tables and musicians, jugglers, acrobats, dancers, and conjurers performing. The hosts hired entertainers to the meal to make it more enjoyable and entertaining. The first course was mainly consisting of salads, seafood, eggs, and mulsum. (Wine sweetened with honey).
