Montgolfier Brothers

Built the World’s First Hot Air Balloon in 1783 in France

Jacques-Etienne Montgolfier

1745 - 1799

Joseph-Michel Montgolfier

1740 - 1810

The modern era of flight lifted off in 1783

when two brothers demonstrated their invention, the hot-air balloon, before a crowd of dignitaries in Annonay, France. Joseph-Michael and Jacques-Ètienne Montgolfier, prosperous paper manufacturers (a high-tech industry at the time), began experimenting with lighter-than-air devices after observing that heated air flowing directed into a paper or fabric bag made the bag rise.

First Piloted Balloon Flight November 21, 1783

Jean-François Pilâtre de Rozier was a French chemistry and physics teacher, and one of the first pioneers of aviation. He and François Laurent d'Arlandes made the first manned free balloon flight on 21 November 1783, in a Montgolfier balloon.

November 27, 2018: Da Vinci Parachute

posted Nov 27, 2018, 3:50 PM by James Falletti   [ updated Nov 27, 2018, 3:51 PM ]

The 3rd Grade class made Da Vinci Parachutes in the Makerspace one week, and completed a series of experiments and that were accompanied with questions. 
  • Students had to drop two (2) Da Vinci Parachutes from equal heights and the same time. One (1) Parachute had only One (1) Paper Clip, while the other Parachute had 2 - 5 paper clips attached to it. 
  • While one student dropped the Parachutes, another student observed which parachute landed first. Each student then marked off a chart - then performed the experiment 5 times in total. 
  • Each student then answered a series of questions based on their observations and hypothesis. 

What is the Da Vinci Parachute?

Though credit for the invention of the first practical parachute usually goes to Sebastien Lenormand in 1783, Leonardo da Vinci actually conceived the parachute idea a few hundred years earlier.

Da Vinci made a sketch of the invention with this accompanying description: "If a man have a tent made of linen of which the apertures (openings) have all been stopped up, and it be twelve braccia (about 23 feet) across and twelve in depth, he will be able to throw himself down from any great height without suffering any injury."

Perhaps the most distinct aspect of da Vinci’s parachute design was that the canopy was triangular rather than rounded, leading many to question whether it would actually have enough air resistance to float. And since da Vinci’s parachute was to be made with linen covering a wood frame, the hefty weight of the device also was viewed as an issue.

Like many of da Vinci’s ideas, the invention was never actually built or tested by Leonardo himself. But, in 2000, daredevil Adrian Nichols constructed a prototype based on da Vinci’s design and tested it. Despite skepticism from experts, da Vinci’s design worked as intended and Nichols even noted that it had a smoother ride than the modern parachute.

Today we continued to fly our paper airplanes and collect data for our little STEM Experiment of how weight and balance affect airplane flight. As we were measuring the distance in Feet (') and Inches ("), we now need to convert all our measurements into just inches. How do we do that? 

Well.... Let's say you had measured the distance of your plane as 11 feet exactly (11').
  • Remember that 1 foot is equal to 12 inches
  • So simply multiply 11 Feet by 12 to get your answer
  • 11 x 12 = 132 inches or 132"
Let's try this one... you had measured the distance of your plane as 15 feet 4 inches (15' 4").
  • Remember that 1 foot is equal to 12 inches
  • Multiply 15 Feet by 12 to get your answer
  • 15 x 12 = 180 inches or 180"
  • ....but we're not done yet. We still have 4 inches left from our measurement
  • So, take the 180" + 4" = 184 inches or 184"
Let's try one more... you had measured the distance of your plane as 33 feet 5.5 inches (33' 5.5").
  • Remember that 1 foot is equal to 12 inches
  • Multiply 33 Feet by 12 to get your answer
  • 33 x 12 = 396 inches or 396"
  • ....but we're not done yet. We still have 5.5 inches left from our measurement
  • So, take the 396" + 5.5" = 401.5 inches or 401.5"
Now it's you turn (Homework)
  1. Complete the 12 Times Table in your STEM Notebook up to 12 x 30 (you may go further, but not less). Make sure it's neat and organized. Remember that if I cannot read it, I will not accept it. Due April 17, 2018. 
    1. Example: 12 x 20 = 240 etc...
  2. Finish converting your measurements that you had written in your STEM Notebook from Feet (') and Inches (") to just Inches ("). This will be turned in for a quiz grade. Due April 17, 2018.

Today we continued our lesson with Spheros. While last week we manually controlled our devices, today we used the draw option.

Log in to with the credentials that I gave you in class and practice. Here's how you're going to get graded each week. 
  • Play Four (4) to Seven (7) Days with 10 Battles to get an "O"
  • Play Three (3) days minimum with 10 Battles to get an "S"
  • Anything less than three (3) days and less than 10 Battles will result in a lower grade
  • Not logging in and practicing will result in a Zero (0)

Bonus Points for anyone who practices Five (5) Days with 10 Battles over the Christmas Break

Also - students need to bring in a one (1) subject notebook to class every week.
  • write your username and password for both your email, prodigy, and any other school program that you use.
  • use the pages as a doodle notebook where you can
    • write out the problems from prodigy as scrap paper
    • design and create ideas for the makerspace
    • brainstrom

Today I let your imagination take control in the Makerspace. Some students built games and mazes for the HexBugs, some created lego structures, while others worked on Arts & Crafts.

Today was Brain Game Day in the Makerspace! 

We played with Circuit Maze (Lessons on Circuits), Gravity Maze (Lesson on Movement and Energy), Laser Maze (Lesson on Angles and How Lasers work), Rush Hour (Thinking game), Trivia, and Dice Games (for probability). It's always a great time when students can learn and have fun doing it.

Today we explored the fun and amazing world of typing and keyboarding...YAY! We used a Google App called TypingClub --> browsed Lesson Plans till we reached "Typing Jungle" --> where we started with lesson one (1) and couldn't move up until we achieved three (3) stars or greater.  We will continue to practice to increase your typing skills. 

Homework: there a a bunch of free or inexpensive typing skill apps/websites/programs available. KEEP PRACTICING!
