light

first we had to list 5 things that were man made and 5 things where natural

Man made	natural
Light bulb	sun
LED	Stars
flashlight	lightning
Flood light	magnesium
Fireworks	lava

then we had a light box and a bunch of things and we had to shine the light in them and record the results

shape	light
Flat m	Reflects in the angle given
Slight c m	Bends the light in to a ‘star’ shape
C m	Bends in to a ‘x’ shape
In c p	Widens beams of light
Out c p	Points the light
Big right t	Pontis -1
Small right t	Bends 2 slightly bends 1 massively
Football p	Slight point
triangle	Bendsend +1
rectangle	Bad point [nothing]
Half c	Point [half point]

here is what we used

light box and conector

shapes to reflect the light

flight 4 the brothers vs the kiwi

this week we had to make a venn diagram on the wright brother and richard pearse. um so heres mine



ya its not that good

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

a hot air balloon

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

matter

 to day we did matter in sci, so we got ice meated it and  the results. here they are

time	temp
1	9c
2	14c
3	16c
4	30c
5	50c
6	72c
7	91c
8	104c
