12 12 Free Floating Hot Air Balloon Experiment Problem Which type of balloon can float the highest? Research Hot air balloons are an exciting way to see the world. They are carefully constructed using very specific measurements and materials. There is a heat source that warms the air inside of the balloon.

21 21 Free Floating Hot Air Balloon Experiment Problem Which type of balloon can float the highest? Research Hot air balloons are an exciting way to see the world. They are carefully constructed using very specific measurements and materials. There is a hear source that warms the air inside of the balloon. References Science Encyclopedia Hypothesis I think the regular shaped hot air balloon shape will float better. Procedure Build two different shaped balloons. Steps for Balloon #1: 1.

Materials - tissue paper - scissors Results I observed both balloons. Balloon #1: I observed balloon #1 with its proper shape floated freely and perfectly up right. Balloon #2: I observed balloon #2 with its square shape, did not float at all. Include graphs and charts in this section.

26 26 Conclusion The student should write what they learned in this last part of the Scientific Method.

27 27 Conclusion The student should write what they learned in this last part of the Scientific Method. It should be stated in terms of the hypothesis – tell whether it was correct or incorrect.

Conclusion My hypothesis has been proven correct because balloon #2 did not float.

29 29 Last Thoughts… Artistry is important. Use color, die-cuts, stickers, etc. to jazz up the board.

30 30 Last Thoughts… Artistry is important. Use color, die-cuts, stickers, etc. to jazz up the board. There are five different types of science fair projects. The layouts and required components are explained in the Science Fair Handbook.

31 31 Journal This is a required part of the science fair project.

32 32 Journal This is a required part of the science fair project. The journal should contain a minimum of 7 entries. Your child’s teacher will give specific instructions for the number of journals entries expected for the grade level.

33 33 Journal This is a required part of the science fair project. The journal should contain a minimum of 7 entries. Your child’s teacher will give specific instructions for the number of journals entries expected for the grade level. It should contain specific information which is displayed on the science fair board.

34 34 Day 1 Today I selected my topic. Hot air balloons have always fascinated me, and I wondered how they worked. I’ve seen different shapes for the balloons, and decided to test two different shapes to see which one floats better. I will need to read about how they are able to fly, and about their construction.

35 35 Day 2 Today I went to the library and checked out 3 books on hot air balloons.

36 36 Day 2 Today I went to the library and checked out 3 books on hot air balloons. (The students should list the books they are using here.)

37 37 Day 2 Today I went to the library and checked out 3 books on hot air balloons. (The students should list the books they are using here.) I learned that hot air balloons are carefully constructed using very specific measurements and materials. There is a heat source that warms the air inside of the balloon.

38 38 Day 3 I learned that the mouth of the balloon must be just the right size. It it is too large, cold air enters the balloon chamber cooling the heated air. If this occurs, the balloon will not float. The skirt also helps to contain the heated air and keep the colder air out.

39 39 Day 3 I learned that the mouth of the balloon must be just the right size. It it is too large, cold air enters the balloon chamber cooling the heated air. If this occurs, the balloon will not float. The skirt also helps to contain the heated air and keep the colder air out. Site the reference source as well.

40 40 Day 4 The heat causes the air inside the balloon to rise. Heating the air causes the air to become less dense. This means it weighs less. The cool air around it is heavier. The heavier air lifts the balloon and it floats.

41 41 Day 4 The heat causes the air inside the balloon to rise. Heating the air causes the air to become less dense. This means it weighs less. The cool air around it is heavier. The heavier air lifts the balloon and it floats. Site reference source here.

42 42 Day 5 The first hot air balloon flight occurred in 1783 in France. A duck, a chicken, and a sheep took an 8 minute flight. The balloon was fueled by burning straw and other material in a fire pit.

43 43 Day 5 The first hot air balloon flight occurred in 1783 in France. A duck, a chicken, and a sheep took an 8 minute flight. The balloon was fueled by burning straw and other material in a fire pit. Today’s balloons are fueled with propane gas. The light-bulb styled balloon shape became standard in the 1960’s. This shape hold the heated air best.

45 45 Day 6 Today I made my balloons. Balloon #1:  5 pieces of tissue paper 20”x20”  4 wedge shapes 20”x4”  Tape together  Attach skirt

46 46 Day 6 Today I made my balloons. Balloon #1:  5 pieces of tissue paper 20”x20”  4 wedge shapes 20”x4”  Tape together  Attach skirt Balloon #2:  5 pieces of tissue paper 20”x20”  Tape together

47 47 Day 7 Today I conducted my experiment. I used a hairdryer to heat the air inside the balloon.

48 48 Day 7 Today I conducted my experiment. I used a hairdryer to heat the air inside the balloon. Results: - Balloon 1: floated freely and upright.

49 49 Day 7 Today I conducted my experiment. I used a hairdryer to heat the air inside the balloon. Results: - Balloon 1: floated freely and upright. - Balloon 2: did not float.

50 50 Day 7 Today I conducted my experiment. I used a hairdryer to heat the air inside the balloon. Results: - Balloon 1: floated freely and upright. - Balloon 2: did not float. Include charts or graphs in the journal.

51 51 Day 8 My conclusion is I would never attempt to ride in a square shaped hot air balloon because it would most likely crash and burn if it turned out anything like my experiment.

52 52 Day 8 My conclusion is I would never attempt to ride in a square shaped hot air balloon because it would most likely crash and burn if it turned out anything like my experiment. My hypothesis has been proven correct because balloon #2 did not float.
