Patents and iventions
of nature I.
We can meet the physical patterns not only in work
of many apparatus, machines and technical
devices but also in phenomenon of wild nature.A
lot of things created by nature are admired by
confessors of technique. A lot of things became an
inspiration for a number of technical inventions.
We offer you in the form of a presentation a how of
the first part of our physiclal research in the world
of alive nature which we make in realisation of
ESF project in our school for SPP. Gradually we
will present more shows by this form. In the end of
the project we are going to prepare a compact
material.
Why the leaves of aspen-tree
shiake all the time?
Leaves of aspen-tree
have got long abeam
flat peduncles (an arm),
so they are in the
unstable position
Why is one of planes in NTM
in Prague called Zanonie?



Zanonie macrocarta is
a kind of pumkin from
New Guinea
Its seeds have got light
arched carrying cots
They´re a perfect
representative of gliding
flight
Why the high reed doesn´t
break in the wind?


Basket of reed is loosy
on the stalk
Leaves turn in the
direction of the wind
and so they have the
smallest resistance
Why frogs have got long
heels?



Jumping-off legs must
supply the whole
energy for motion
They have got stronger
muscles
They act as crows
Why whale which has got
lungs doesn´t survive without
water ?



The weight of whale
is 90 – 100 t
In the water the
weight is balanced
by lifting force
On land the big force
of gravity presses the
vessels and
problems with
respiration appear
What skeleton has the earth
worm got ?




Earth worm has got a
hydrostatic skeleton
It is as a bag of water (outer
lays of body surround a
cavity full of of liquid)
Water is incompressible
(when outer lays of
organism press on water,
water presses back and
reclines the body of the
animal)
This skeleton helps in
motion, it is flexible but it
doesn´t provide prevention
What is cucujo interesting in?




It is American linkboy
Beatle 3 – 4 cm
It has got 2 yellow shining
pimples on the sides of the
nuchal clypeus
The spare protein is
changed by ferment into
shining mass= luciferin, the
second ferment enables
rich oxydation during which
energy-light is emited
Does the reactive drive exist in
botanical land?


Plant splashing
marrowíkavá (splitting)
Being touched the
contain with the seeds
splashes and the
cucuber-like seed
moves the opposite
direction
What stalk have the water
plants got?



Flexible stalk
It is kept in the vertical
position byuplift power
In huge waves a hard
stalk can be broken by
se tvrdé stéblo mohlo
zlomit
What is the fly diopsida
interesting in?



It has got the eyes
placed on the ends of
long cirris
This way its vission
angle gets
It can mention the
danger in from the back
and the front
Why the second name of the
plant lettuce is compass?




The leaves are placed
in one direction northsouth
The plant reacts on the
movement of the sun
In this position it
prevents the
overheating of leaves in
the noon
The smallest ammount
of water evaporates
during the whole day
Why do the ducks twinkle while
walking?



Their legs are more for
paddling and so they grow
far from each other
When the duck rises the leg
it starts to fall to this side
By twinkling it keeps the
ballance (the vertical axic
crosses just the flat of the
leg which touches the
ground)
Which animal has got a
periscope?


Fish periophtalmus
It digs itself into
swampy bottom and it
pushes its eyes up on
foot-stalks to observe
the surroundings.
Where can we find an arm on
sage?





In the floret of sage
Stamens are the shorter
beam of the arm and pollen
is on the end of it
The shorter beam protects
the enter into the floret
If a bumblebee enters a
floret it presses the shorter
beam
The long beam touches its
back and leaves some
pollen on it
