Our First Visit - Politechnika Poznanska
On 13.October class II a with a few students from class IIIa and Gimnasjum nr 2 went to Poznań.
After we came there we headed towards POLITECHNIKA, where we experienced some interesting
lectures.
At first we saw ,,Zróbmy maszynie EKG”. It was a study about analysis of vibrations in
diagnostyka of technical machines , which was conducted by dr. Inż. Roman Barczewski.
Then we went on the best one, that we saw on uniwersity! It was called ,, Bitwy sumorobotów”-it
was a presentation of Koło Naukowe Studentów Automatyki i Robotyki CYBAIR- that was the most
exciting of all!
The sumo combats between robots were very spectacular. The robots had to pull the others out of
the matt- a really interesting show!.
Finally, we went to see ,, Odnawialne Ľtródła energii-elektrownie wiatrowe – drgania i
hałas”conducted by dr Maria Golec and prof. Zw. Dr hab.( I’d also like to have so many words
before my name :P)Czesław Cempel
It was a lecture telling us, from which energy should we benefit and what to do to the benefit
was nice to environment.
I have to say that they were very didactic lectures and we could get to know a lot about university life

Second Visit - UAM Poznań
We have visited University of Adam Mickiewicz in Poznań :)!
 On 17th my class I a and a few students from class II a, III d and Gimnasjum nr 1 went to University of Adam Mickiewicz in Poznań, where we attended a very good lecture called: “Mars after inspection first robots inspection – when will people land there?” conducted by prof. dr hab. Edwin Wnuk. Our leading teachers were mgr Elżbieta Rzepka and mgr Witold Pertek. The lecture started at 10:30. Many things concerning Mars were presented, among others:
- Short informations of Mars
- “Great resistance” – Do you know what is this? Thanks to lecture I know :-)! This is such position of Mars and Earth, when journey from Earth to Mars is the shortest – “only” 180 days. “Great resistance” was in 2003.
- Is there water on Mars?.. Scientists say: water was on Mars because we can see this in the photos – there are many trails for it. But now probably water is only in Mars as ice.
- Life on Mars. (I expected stories about green extraterrestrials… but now I know they are only invented by people:-) ).
- Expeditions to Mars (also in the future).
- Finally we could listen about : When people will land on Mars...
 The lecture was very interesting. My class was under impression. After lecture we were sightseeing the university (it is a beautiful and modern place). In the center of the University there is a very interesting clock (or whatever...), we could also see beautiful images and sculptures made by students.
I hope there will be more trips like this because it’s a great experience.

Birds of Prey
On the 24 November the interested students of our school could listen to a really impressive, illustrated with numerous slides lecture on BIRDS OF PREY by a scientist from Poznań Agriculture Academy. The lecture was organised thanks to the funds in our project YEAR WITH SCIENCE-financed by Polska Fundacja Dzieci i Młodzieży and Polish American Freedom Foudation and sponsors: Trzcianka forestry management. One of the students-Ola-wrote down some interesting points about those birds. here is her article. (Read and learn the English names of some important big birds of Poland!)
BIRDS OF PREY
Almost all species in Poland except for few for example wildboar (Sus scrofa), roe-deer (Capreolus capreolus), deer (Cervus elaphus) are legally protected and some of them are not welcome like mice (Apodemus agrarius) and rats (Rattus norvegicus). In Polish Red Book are the most endangered species and beasts of prey are the ones who are very important to protect.
Beasts of prey have been persecuted for 2000 years since people started to change forests into fields and living space decreased. When guns were discovered in XVIII century people started to kill them in higher numbers The feathers of birds of prey were in fashion – the number of beasts of prey drastically decreased. Also using DDT in fields (on 1 hectar – hundreds of kilograms) were poisonous for beasts of prey. Manure with rain got into water containers like lakes, rivers. Lakes are polluted because of manure and chemical fertilizers- phosphorus and nitrogen - algae are growing fast then. Fish eat algae eaters and that way DDT is getting into the body of birds of prey. DDT is being accumulated and it can’t be excreted. DDT makes birds’ egg-shells too thin and birds crush them while incubating. In spite of officially withdrawing from DDT production in 1979, it still had been sold under different name. It didn’t give any results even when DDT was finally withdrawn. Birds fly away for the winter to Africa , where DDT is still used and it still is being poisoned.
The most dangerous for beasts of prey is civilization. Cutting down forests causes birds habitat to decrease. Phone and energetic lines are also quite dangerous. Education is very important. Lots of birds are dying because of thoughtlessness of farmers and also a lot are dying because of mistakes made by hunters. The number of beasts of prey is now 1% of primeval population. At our times in Europe there’s only 37 species of birds of prey left.
Recognizing birds starts with the size, that’s wingspan. The biggest is the Vulture – very rare , about 3 meters. Then the Eagle with 2,5 meters. To average size are: Hawk, Buzzard, Honey- buzzard; with 1,30- 1,50 meters.
Here are short notes about some, most popular birds of prey in Poland:
White-tailed eagle's nest not far from Krzyż
Buzzard
*Kite (Milvus migrans-kania czarna and Milvus milvus-kania ruda). It’s easy to recognize. The tail has on every side 6 feathers, which have different length- it’s called bifurcated tail. That’s the easiest way to tell this species from the others. The nest of kite is very characteristic. It puts papers , foils, strings (it can for example hang itself on those strings) into the nest. Kite lays eggs every 2nd, 3rd day. The first who is born has the biggest chance to survive. Kites are also living in Czarnków- Trzcianka administrative district.
*Golden Eagle (Aquila chrysaetos-orzeł przedni). In Poland lives 50 specimen. Life – expectancy rate is 30 to 50 years. It has only one nestling. In spite of 2,3 eggs. The strongest one kills weaker nestlings. It has feathering legs and bright ruffed head. It’s one of the biggest birds in Europe.
*White-tailed Eagle (Haliaeetus albicilla-orzeł bielik). Wing-spread is 2,30 to 2,50 meters. Females are always bigger, sometimes male is even a half smaller ( 300-350 dag). Eagles nests are huge , those weight 500 kilgrams till 1 tone. The biggest nest in Poland is 2,5 meter wide- it’s in forest inspectorate Podanin. Eagles are using the same nest for many years, adding to it every year something new. Eagles nests in Poland are protected.
*Great Spotted Eagle (Aquila clanga-orlik grubodziby).It’s very rare- in whole Europe there’s only 17 couples – all in Poland in Biebrzański National Park.
*Lesser Spotted Eagle (Aquila pomarina-orlik krzykliwy). Only one nestling is alive (kills weaker) It has bright wings and eats small rodents and average – sized birds like Pigeon (Columbiformes) , Jay (Garrulus glandarius).
*Booted Eagle (Hieraëtus pennatus-orzełek). It’s sized like the buzzard , and living probably in Białowieża forest and Bieszczady mountains. It eats green lizards.
*Osprey (Pandion haliaëtus-rybołów). Osprey nests is on the highest tree on the top. When osprey wants to fright its enemy it spreads wings. Ospreys are living 20-50 years. For long- lived beasts of prey DDT is especially dangerous. Nestlings don’t kill each other.
*Griffon Vulture (Gyps falvus-sęp płowy). It lives in the south of Europe. It has 3 meters wingspan. 1000 km is not long distance for it. In the past vulture was more numerous , now it’s in danger of extinction because of lack of carcass (padlina).
*Montagu’s Harrier (Circus pygargus-błotniak ł±kowy). It’s grey . The nest is on the ground in rushes , on fields . Quite high numbers in Noteć valley. The Harrier eats rodents.
*Hen Harrier (Circus cyaneus-błotniak zbożowy). In Poland probably only 10 couples.
*Buzzard (Buteo buteo-myszołów zwyczajny) . The most common bird of prey. It eats field-voles. There’s about 30-40 thousands of couples- just like storks. All the species of birds of prey are less numerous than buzzards. Buzzardshave different coloration.
(Buteo lagopus-myszołów włochaty)- In the winter time buzzard lives in Poland. It’s marked off tail color white with black stripe. Feathering legs.
*Honey buzzard (Pernis apivorus-trzmielojad )- It hunts for hymenopteron ( bees, bumble-bee ) eats larva. Honey buzzard comes to Poland in May. Nestles hatch out in July.
*Sparrow hawk (Accipiter nisus-krogulec) -The biggest sex dimorphism- male is twice smaller than female. 5-7 nestlings.
*Falcon-Peregrine (Falco peregrinus-sokół wędrowny)- The fastest bird in the air. It’s flying down with the speed of 300 km an hour. Falcon weights till 1 kilo. It became extinct because of DDT. Polish ecologists are trying to reintroduce this species.
*Kestrel (Falco tinnunculus-sokół pustułka)- Sometimes kestrel exists in Trzcianka. 1 couple in Czarnkowsko- Trzcianecki administrate district. It used to be the most popular beast of prey in Poland. Why did it excint? No one knows. Probably lack of place to nest.
*Saker (Falco cherrug-raróg) – Only one couple in Poland on the border with the Czech Republic.
Probably a marsh harrier (błotniak stawowy)
(Sorry, in the photo above there is a stork, not a bird of prey)
Civilization nowadays causes the population of the birds of prey to decrease drastically Although ecologists are trying to protect them, the situation is worse with every year. Beasts of prey have less and less living space. The only thing what we can do it’s to change our thinking. We have to try to rescue them because the violation of ecological balance is really harmful for the environment. Contemporary society is blind to this problem, but we all should believe that something will change.

Molecular-Biological Machines
On the fifteenth of December 2004 students mainly representatives from biological classes : I , II, III went by bus to UAM in Poznań to listen the lecture entitled : ” molecular biological machines” . The lecturer compared physical machines with among others human metabolism, especially to oxygen breathing process and striated muscular tissue.
To my mind this lecture was very interesting for us, young biologists, particularly for students from 3rd class because they have had this material so they picked up extra curiosities with pleasure. Then all the students went to visit Biology faculty in this University. Who knows, maybe these aesthetical buildings and this interesting lecture will encourage somebody to choose this faculty in this University.

Mobiles at UAM
On 12.01.2005 several students from our school went to Poznań for a brand new lecture: "Mobile Phones today and in the next 10 years". Lecture was at UAM and the lecturer was prof. dr hab. Witold Hołubowicz
from the same University where he teaches at the Physics departament.
We learned many interesting things form this lecture. Did you know that the mobile phones have been available
in Poland since 1996? Yep, today a mobile is a part of our life, but in 96 you were only able to talk on your phone, there weren`t any things like sms, mms, mp3 player etc.
Next cool thing is GSM, it`s a net`s standard for cell phones but do you know that there are 4 standards in the entire world? Yes, but GSM is an European standard
(with some Polish things from our scientists) and it`s the best standard of all.While the lecturer was talking about phones he showed us many cool models of phones. From 1990 "Cegła" to the newest mobile with mp3 & movie player.
Besides mobiles the lecturer was talking about GSM net. Do you know where does the "Cell phone" name come from? We know ;). Our world is divided into areas where you have "pole" or just range where you can use your mobile without interferences. These areas are just cells :D. There are many things to talk about, but if you want to hear them you can just download a movie from this lecture from www.wo.amu.edu.pl and see it for yourself.
After the lecture we had 1 hour to tour the UAM o(Mathematics faculty`s canteen rulez). At 3:00PM we were back home. I think that the Lecture was cool and I surely will go for the next one.

Rubens Tube
On 16th February we (some people from several classes) went to Poznań to UAM (physics faculty) for a lecture about acoustics. The lecturer was prof.dr.hab. Wojciech Nawrocik (in the picture on the left). The lecture was very interesting and prof. Nawrocik showed us many cool experiments like Rubens tube (it looks like winamp visualisation :) ) or Rickey tube. Unfortunately we haven`t seen all the lecture because our bus was late, so at the beginning we were a little confused. Than we had one hour to tour university (mainly the cafeteria). At ~15:20 we were back in Trzcianka

Vibrations and Acoustic Waves
On 16.02 several students from our school went to Poznan for next lecture at UAM. The lecture was about "Drgania i fale akustyczne cz. III" which
means: "Vibrations and acoustic waves part III". I came to the bus stop at 8:05 am and I heard terrible news: "our bus will be late and it will arrive at 9:30 AM". I said: "Yeah, only an hour and a half to stand in this snowy and windy place, just great :/" but then I remembered that the lecture is starting at about 10:30 AM so we have only one hour to drive to Poznan (bus goes about 2 hours usually) so the day didn`t start so good as I planned :/. At 9:30 bus arrived and the driver said bravely: "We will do it" then he put his plan into practice and we were driving very fast towards Poznan :). I tought that we would be there on time but in Oborniki I saw strange thing - driver turned on in the wrong direction: everyone was shouting: "man! what are you doing!?" but
it was too late! We just lost several minutes to come back on the right way. At 10:30 we were 25km before Poznan. I said okay, we`ll loose some opening words but we will be there on the lecture itself. We were in Poznan at 11:05 and then I knew that that day wasn`t very lucky and it would be less lucky in every minute: the driver didn`t know way to Morasko - the campus of UAM where lecture was going on :/. He was driving around and finally he asked a pedestrian to show him the way - just great :|. Okay, don`t panic, it`s still something to see on the lecture I hope ;]. It was 11:35 when we safety arrived at UAM. We ran as fast as possible to the Auditorium Maximum and we just burst in tears: there was no sits available at this room. So we sit in a smaller room and we started to listen to the lecture and watching it on small projector(lecture was transmitted to the 2 smaller rooms - thx goodness). There was only 25
minutes to the end of lecture so we didn`t know what it was about :/. There were some some unidentified wave graphs on the screen for few minutes so we were angry that we didn`t came here earlier. But at the end there were 3 interesting experiments. Firstly prof. W. Nawrocik who was leading this lecture showed us how straight acoustic wave looks like. He was tapping long spring so it was waving in a defined periods. In a middle of the spring there was a small red ball. Prof. showed to us how to tap the spring that the ball was still on its place - not moving (it was straight wave). Next experiment was "Concert on 3 pipes" :). Prof. took 3 long pipes with 3 sieves inside, when he burned all pipes and plant the microphone inside, the pipes were playing some strange sounds - it was pretty cool. Then lastly he took out a big pipe with many holes on it (Rubens Pipe) and plugged it to the bottle with gas. Then
he planted a speaker to it and started to play some music on keyboard plugged to the speaker. Then suddenly many flames showed up from those many holes :). Flames were moving with the music - same effect like equalizer in Winamp :) - yeah it was really cool to see it in real life :). And it was the end :(. Not much to see but it wasn`t fault of the lecture ;) (damn you driver!). After the lecture we visited Molekular Physics Institute. Hour after this we were back in the bus. But the funny journey wasn`t over. In Oborniki (please! not again!) driver again screw up his job and turned into the wrong way again! (arghhh). Many people were sleeping so before we found the driver's mistake we were going back to Poznan for many miles. The journey home lasted about 2 hours and a half :/. At last we arrived in Trzcianka and thx goodness again for that. It was superb subject for a lecture but we didn`t enjoy this for much ,but I hope that next lecture on 12.03 will be better for us and we will arrive at the right time. Sorry for this long report but I`m so angry that I must write it ;). Okay, that`s all folks. Today`s report was sponsored by number "2" and leter "a" :). See you next time at UAM P.S. Fortunatelly this lecture will be available on the internet so you can see it for yourself in a couple of days :) address is the same: www.wo.amu.edu.pl See ya fellas!

Chemical oscillation reactions-a lecture in our school
On 8th of March in our school professor Anna Szarek organized a very interesting lecture about chemical oscillation reactions. Our lecturer was dr Jerzy Stanek who works in UAM in Poznań. He presented in a very interesting way this difficult problem. In the beginning Doctor wanted to catch our attentionso he showed as an experiment that presentet a process one of one oscillation reaction, but unfortunately ended with no results. In fact it has happened many times in the complicated domain that chemistry is;] Every problems of the lecture was presented on a multimedia display. Doctor Jerzy tried to explain us the topic with examples from everyday life and he did it with great sense of humour. He showed as how mathematic record of an oscillation reaction looks like and that it is closely connected with fluxional equalizations. It’s so complicated that it’s certainly why this problem is not talked over in Lyceum. Oh… that’s a pity; ) Generally the lecture was very interesting. If you missed it, regret!

Lab in SAPA
On 25.02.2005, participating in "Year with Science" project, twelve students from our school who are preparing to the Chemistry Matura exams - with prof. Anna Szarek, visited chemistry lab of "SAPA ALUMINIUM" company. The leading technology engineer - Przemysław Paech, presented us shortly the theory of oxidization and reducing
reactions. Then, with some help from the lab workers, we carried out some cool reactions, which helped us to understand information from our Chemistry lessons. Knowledge from this form of lesson will be useful soon at Matura exams on 20.05. This kind of meetings will probably be sheduled every two weeks.
