Last week IES Södertälje took 30 budding scientists from year 7 to “ Tekniska Museet “. Maryam from grade 7 writes her experience of the day.
The day started with a presentation by Swedish scientist and astronaut, Christoffer Fuglesang , Professor Joli Gold, and Professor David Sampter from Scotland.
In Christoffer Fuglesang's presentation he presented the journey to Space, how he prepared and why he was sent to Space .
Christoffer explained that he joined NASA and went to Russia to prepare himself for the big journey. He was trained for his Space mission underwater and in the air. He was sent to Space because he was going to build the Space station, so he brought many things from earth to Space and he also fixed the solar panels in Space. After 14 years of training he finally made it. The whole launch process from NASA to Space took about 8½ minutes. He spent 13 days in Space. Professor of bio material, Joli Gold spoke about how to grow meat artificialy and Professor David Sampter from Scotland had an interesting presentation about artificial intelligence.
After the interesting lecture we got to investigate part of the museum for about 20min. There were a lot of activities that used your five senses and modern technology.
After lunch we met Maria, Marika and Lina . They explained about how Photovoltaics with sun light made energy , the photon gives the energy to the electrons which makes a movement. With stronger Light you would get more energy which makes the electrons to have more current. To calculate the power of an object you will need this formula : p (power) = c (current) x v (voltage). It was very interesting , we used different types of scientific material for example the ammeter.
From the scientist from KTH we learned a very interesting thing which was about the special glue that they had investigated . It was a non toxic substance that had molecules that the body recognized. This is a cheaper and better way to repair skeleton if it gets damaged, because now and before they used to used metal to fix the problem but the skeletons that will have the glue will be more flexible, said the scientist. All of the research for this glue took about ten years. We also learnt about another subject which was cement mixed with water, it could also be good to fix damaged skeleton. They fill in the empty space in the skeleton and then over time the skeleton starts to grow and the cement disappears. To actually know how strong it was,we made small bones from cement.
Then Sara from KTH showed us a robot named "Pepper". A robot that is a social robot that means it looks like a human. It could help people to organize things, refer objects and the robot knows conditions ( etc ). As scientists, they are working on how to make them more social. We did an activity with the robot which was that we pointed at an object in the table and it was going to tell us where it was . That was really cool and interesting to watch.
With another scientist we played a game , and by that game we saw how the robot was looking using a computer. The robot had a hard time identifying different things with the same color. It was a great experience to see how you and the robot were communicating by a game.
The last thing we did in this amazing museum was to walk around the museum and to investigate all of the technological objects. We saw different types of robots , the development of different objects for example the development of the mobile phone and the vacuum cleaner.
This day was a fantastic day with a lot of new things that we learned from great scientist from all over the world.
