flight 2-aerodynamics

aim: to look at the 4 main forces of flying and how these can be overcome.

Hypothesis: I think that.......

Method: Working in pairs we are going to make a paper wing and experiment with it.

1. Make a paper wing out of A4 paper 

1. On the field you will need to record and observe how 5 different changes affect the way it flies.

Plane type	How does it behave?	Time ( secs)
Paper sheet, drop		2.11
Paper with fold down middle, drop		1.42 shut 2.67 open
Paper with fold and 1 paper clip, drop		1.48 shut 1.37 open
Fold, 2 clips, rudder, drop		1.15 shut 1.22 open
Fold, 2 clips, rudder throw		5.41 1.65

flight 3 the first flight

The first flight was not in a plain it was in a balloon

1670 was when italian priest Francesco de lana comes up with the thought but never makes it

14 september 1783 was the day the first fight with a living thing was taken i think.

Then the french academy of sciences asked jacques charles to invent a scientific flying machine so he makes the hydrogen balloon

It was tested on December 1, 1783.

here is more on the flight with the living beings

Joseph montgolfier and his brother jacques made paper. One day joe was watching sparks float up the chimney and figured that it was the hot air making them float. He then filled a silk bag full of hot air to see if it would float. It did. He made bigger and bigger until he made a full size one. The brothers put 3 amamale in the first flight a cockerel, a sheep and a duck

They were rewarded by the king with a gold medal. The sheep was also rewarded by getting a home in the royale zoo

here's a diagame

flight 1

things that fly 

Natural	Man mad
Bugs	Plane
Birds	Paper aeroplanes
Dragons	Helicopters
Dinosaurs	Balloons
Bat	Jet

Lift:where the air pressure is greater under the wing than on top of the wing 

Drag:the force to slow down a plane/bird

Thrust:the forward movement of a plane or bird

Gravity:the downward force on a plane or bird 

Aerofoil: the shape of the wings of planes and some birds 

Bernoulli effect: the more wind under the wing forces the wing up crating lift when the wing is in a aerofoil shape 

Activity 1: Your challenge is to hold a rectangular piece of paper close to your mouth, blow across the top of it and get the paper to move down. Sounds simple enough but give it a go and see if you change your mind.

What is happening?

the paper will rise and you will get light headed

mega air

yesterday me and 15-16 other chosen children all though the school went to Mega Air. the teacher aids/helpers won a class trip to mega air, so they all picked some kid that they think deserve to go. I was so excited when I got told as I had never been to mega air. so when the day came I was unable to sit still, well I had to I was in school, but you know what I mean. we left at about 11:40 and came back at 1:20 lunch we had spent about 2 hours! any way we got out of class at 11:33 and went to the meeting place [the learning center] and took the role. then we walked 100m to mega air. when we got there we had to take our shoes and socks. then we watched the safety video. then we were let loose, and I was so happy. about 3 min in I went to jumped into the air bag but I was scared. but I went and did it after 5 attempts and it was its so fun so I jumped in over 10 times over the time we were there. after we had our time everyone was happy but tired. so that is my recount of mega air.  👍 👋

word cloud

today in science we did a test and then a word cloud heres mine 

then we got our resotes out of 36 and i got... 30
