Transcript: The Hot Air-Balloon Invention First hot air balloon was made in 1783 Launched it in December 1783 First passengers in the hot-air balloon was a rooster, sheep, and a duck (animals did survive) The type of hot-air balloon was the Montgolfiére The envelope was made from fabric lined with light colored paper, and a layer of alum coated the envelope to prevent it catching fire. The balloon was tied together by a series of over 2,000 knots Montgolfier brothers French Brothers were two of sixteen Montgolfier children, many of whom worked in the family paper factory in France Made the first successful hot-air balloon Advantages/disadvantages Advantages hot air balloon materials and construction have changed since the 1700's part due to increased interest in helium balloons, which allowed much higher flights. were used in war and sport Ballooning has also gained great popularity in Europe, and in Australia and New Zealand. Disadvantages The popularity of ballooning declined after World War I, in part due to the price of fuel Background history The hot air balloon is the oldest successful human-carrying flight technology. It is in a class of aircraft known as balloon aircraft. The first fight with humans on board took place on October. 15, 1783. On November 2, 1783 was the first free fights with passengers The first military use of a hot air balloon happened during the battle of Fleurus in 1794 where the French used the balloon as an observation post. Facts and Ideas Unmanned hot air balloons are popular in Chinese history. Zhuge Liang of the Shu Han kingdom used lanterns for military signaling. Diseases tuberculosis also known as TB was a disease that would attack the lungs. TB affected those who had been poorly fed and were under nourished. It also affected those who lived in dirty and damp homes. This was an issue because it was easy to spread the disease so lots of people died from it. Advantages and disadvantages The advantages of TB is that they improved the medical technology. The disadvantages of TB was that it killed many people. Background history of TB In 2008, evidence for tuberculosis infection has been discovered in human remains dating from 9,000 years ago, in a settlement in the eastern Mediterranean Signs of the disease have also been found in Egyptian mummies dated between 3000 and 2400 BCE. Facts and Ideas started in the 17th century and lasted for two hundred years, known as the white Plague The high population density as well as the poor sanitary conditions Further Understanding This disease couldn't be avoided because it's spread around easily, also it is one of the oldest diseases around. If I went back in time I would tell the people to not live in dirty and damp houses because you can get TB more quickly. I would tell them to stay away from people who had TB. Also I would tell them to eat healthier. ... small By: Megan Jong The first balloon passengers were a military officer and a physics professor. the professor went on to become a balloonist, although he was killed in a failed attempt to cross the English channel by balloon a few years later, when a smaller hydrogen balloon attached to his hot air contraption caused the entire balloon to burst into flames. Big and....
Transcript: Hovercraft Featuring Bailey, Josh.s and Lochlan Using Only 1 Disc = $0 5cms of paper = $100 3cm of Sticky tape =$15 A total cost of only $115 We have decided to construct a contraption following the structure of a hovercraft Our Aim To hover over the LPAC stage further than other competitors And if your thinking it is really easy Well... ITS NOT After a whole lot of testing and collecting data and working If your thinking it all worked perfectly the first time? IT DIDN'T We faced a series of problems including The Disc becoming caught on bumps Lochlan being an idiot After a whole lot of fixing and repairing we managed to finally get it to work Here's what we finally ended up with Well as you can see it looks like it will work IT DID but there was to much friction against the disc causing it to slow down After lots of tests We finally got a data table looking like this and graph As a group we have noticed some strange patterns we found out that with two or more weights loaded, the weight was balanced therfore it made it slide further heres a video of our hovercraft in action Thanks for watching Back to work
Transcript: Step 1 Quiz star We had to research and take the quiz on quiz star to start our bulid. In order to do that we had to get a passing geade on it witch is a 70% and above. Step 2 Blue prints We had to draw out what colors on witch gores and decide where to put them eather top or bottem to complete out envolpe. Step 3 Tracing Gores We had to trace the gores on a white piece of paper, And transport them to the tissue paper. Step 4 Glueing the Panels We had to glue the bottem to the top panal with the bottom one over lapping the top by an inch. Step 5 Glueing all the bottems together We had to lay out all of the gores and glue the bottems to the other bottems. With over laping by an inch. Step 6 Glueing the tops together We had to lay out the glued bottems with the tops not glued and glue them to make a circle in a way by also over laping them by an inch. Step 7 Making the vent We had to cut an arms length of string and tie it around the top so its closed so no air can get out. step 8 Making the ring We had to get a piece of long hard paper and flip an inch of the bottem over and staple it so it makes a good support for the launch pad. Step 9 Testing to find holes (air test) We had to put our hot air balloon on the air test to see if there were anywholes. And fix them up if there were. Step 10 Launch The launch was in the gym we were greaded on how high it went if it hit the ciling its 100% lower 75% and so on. Jadyn Beebe Engineering period: 3 Hampton
Transcript: Step 1 Step 2 Step 3 Step 4 Step 1: Quiz + Research Paper The first step of the assignment was to take a quiz on the history and mechanics of the Hot Air Balloon with a passing grade. The class was given a sheet of paper with the questions from the Quizstar and it was our job to search the internet for all the answers. Once that was completed, we were allowed to take the Quiz up to three times until a decent grade was achieved. I searched all the answers (finding the majority of them) then took the online quiz. After a couple of times, I got a low B grade, but I took it an extra attempt to at least get an A, considering there may have been some important terms I got incorrect, and I got a 92% as my final score. Step 2: Blueprinting After our Quizstar was completed, we were assigned a partner to cooperate with for the rest of the project. There would be some cases where a partner’s cooperation would be needed to process the build more smoothly, but first they would decide on the color panels the balloon would have as well as the order for the blueprinting on a paper given to them pre-sketched on, rather than graph paper. By the time I was assigned my partner, he was just about done with his own quiz, so I got his opinion on the colors and wrote the labels onto the Balloon Design Worksheet, anticipating how the panels would be put together, how the gores would end up, and in which order. Eventually, we agreed on using blue, green, and purple for our color selections. Step 3: Cutting/Tracing/Gathering the Panels Gathering, tracing, and cutting the panels would require cautious work with the tissue paper. The very beginning of the process was cutting an outline or base panel of both the bottom and top versions, and then gathering our twenty sheets of tissue paper (having 20 panels equal to 10 gores.) Once we had those materials, the task was to trace ten bottom panels, ten tops, and cut them out as neatly as possible without wrinkling or tearing the paper. This step went more smoothly than I thought it would be, even though a few of our panels needed some patching in the end. The only problem was that it took a period longer to cut than necessary, but after coming in during lunch for some extra work time, it turned out well enough. Step 4: Gluing the Panels to create Gores Gluing the bottom panel over the top by an inch was the first of three gluing steps. According to how the blueprints looked, two panels would be combined to create one gore of the color choice. Once ten gores were ready, we had to glue all the bottom gores side-by-side by one inch as well, so that it’d create a flower shape before finishing the envelope. Keeping track of all our panels and making sure we had enough tops and bottoms was a hassle if we didn’t stay organized, but even then I made several mistakes from gluing tops over bottoms, pasting together two of the same panels, and getting the color codes wrong. This step also took quite a bit of time, but the result was relieving. Tranforming into 3D from 2D Transforming a flat, 2D shape into a 3D object that would eventually lift off the ground was the most difficult part of the project. By this step, the bottoms of the gores have been glued and the only thing left to do with the envelope is paste the top panels together. One partner would do the gluing; the other keeping the panels leveled with each other until the last gores were combined, then the balloon shape would form. My partner and I took turns with the glue and keeping the tissue firm, and the first couples were harder than I thought they’d be, but with every gore we got done, it gradually became easier. It was more than a relief to have finished this step successfully and barely on schedule. Attaching the Rim The only thing to do in this step was to cut approximately a two foot long strand of firm paper. This would act as the rim for the bottom of the balloon and to attach it, a few staples would be needed over an inch or so of paper folded over the strand. This also solves any problems with uneven ends, to our benefit. Our rim was a bit longer than two feet, but it worked out fine with the assistance of my partner. I held the tissue paper and rim in place while he stapled the tissue to the stand several times for extra binding. (no picute) Tying the Insulator. This was probably one of the easiest parts of the project, as long as there was a diligent partner to help. All we had to do was cut a string about arm’s length and tie it around the top of our balloon. If done right, the hot air should be trapped inside the envelope, instead of escaping through the top. The hot air, when locked, would rise with the balloon, but if done incorrectly, there wouldn’t be chance that the balloon would ever lift off the ground. This step only took a few minutes and, thankfully, I had a good partner. He held the ends of the balloons while I tied the string around an extra couple of times just to assure the tightness. We cut the supplemental
Transcript: Made from only tissue paper. Boyle's law shows that, at constant temperature, the product of an ideal gas's pressure and volume is always constant. The early gas laws were developed at the end of the 18th century, when scientists began to realize that relationships between the pressure, volume and temperature of a sample of gas could be obtained which would hold for all gases. Charles's Law Balloon Development Hot Air Balloon Gay-Lussac's Law Charles's Law, or the law of volumes, was found in 1787 by Jacques Charles. It says that, for an ideal gas at constant pressure, the volume is directly proportional to its temperature. Boyle's Law Avogadro's Law Cut out 8 sheets of tissue paper. Hot Air Balloon Avogadro's law states that the volume occupied by an ideal gas is proportional to the number of moles (or molecules) present in the container. Use small piece of scrap tissue paper to enclose top area of the balloon. Connect gores by gluing edges together. Works Cited Gay-Lussac's law, or the pressure law, was found by Joseph Louis Gay-Lussac in 1809. It states that the pressure exerted on a container's sides by an ideal gas is proportional to its temperature.

Transcript: Step one! We did research and took our Quiz Star exams! I got 21/25. We had to research ideas on how to build a good design. Step two! We made blueprints for our HAB. We chose the colors for our panels. Mine and Bridger's was supposed to be a rainbow, but it was kind of just a bunch of random colors :) Step three! We traced out the pattern for our panels. Once we had that traced and cut out we cut the gore into the top and bottom panels so we could use it to trace the panels for our envelope. We had to make sure we cut it out straight so they'd line up when we glued them Step four! Once we had every panel cut out, we glued the panels together to make our gores. We had to make 10 gores and 20 panels. We to make sure that we glued them together an inch inwards, and not very much more than that. Step five! After every panel was glued together to make a gore, we glued all 10 gores together to make our envelope. We had to make sure we didn't tear the tissue paper. Step six! We had to glue the two ends of the gores together to make the envelope. It was tough getting it perfectly enough that it didn't have too many wrickles and that it didn't rip. Step seven! We cut an arm's length of string to make a tie so we could tie it at the top of our envelope so the hot air wouldn't escape. We tied the string to the top as tight as we could. Step eight! We made the ring in this step. The ring helped support the tissue paper when we launched it. We used dry wall tape to make the ring. Step nine! This step was when we tested our balloon. We tested it to make sure that there wasn't any holes in our envelope. To test it I held the balloon on the launch pad and Bridger went around marking the holes with a marker. We had 4-5 in ours. Step ten! This was the launch!!:) We got 100%! But ours went kind of lop sided because the left side was a tad heavier than the right, but we still aced it! :) Yay!

Transcript: Graph Gas is heated in the balloon, then its volume increases. As the volume of gas increases the balloon becomes filled with air. Soon the balloon is full of hot air. A hot air balloon is less dense than a balloon filled with cool air outside because of the ideal gas laws. Hot air ballons and the Ideal gas laws How the Ideal gas laws power the hot air baloon. Pressure multiplied by volume divided by temperature. This is basically what powers a hot air balloon and the major concept of these things. Andreas Adell Gas law of hot air balloons
Transcript: Hot Air Balloons The hot air balloon is used for traveling, to carry people & cargo. The wind guides the hot air balloon. The story starts that in the 2nd century BC someone made an expirenmental hot-air balloon out of an empty eggshell. The hot air balloon has a bag called the envelope that can contain heat in it & on the bottom it has a basket called the gondola or wiker basket that carries people. The hot air balloon was created by Joseph-MIchael Montgolfier on 220-280 AD. The heated air inside the envelope makes it light since it has a lower density than the cold air outside the envelope. The light frigtened the enemy & helped the Shu Han to win the battle. It made it better because instead of walking place to place they can just take a hot air balloon & travel.Some ideas are planes,jets,& blimps.
