Field Trip!








Yesterday, Tuesday April 20th we went on a science field trip to a planetarium. We had 2 guides the first guide talked about space and the first spacecrafts that were launched etc. The guide told us about pollo 11 the first spacecraft to ever land on the moon! Apollo 11 was launched on July 16th 1969. Apollo 11 was owned by United states







As the guide continued on he showed us the first satelite ever launched. It was called Sputnik ll and was launched in late november 1957. Sputnik ll had a animal launched in it by the name of Lakia. Sputnik ll was the size of about 5 bowling balls mashed together to create on huge bowling ball. The dog was taken to space to see if humans could actully space travel, however the poor animal died after a couple of hours due to overheating and stress and panic. Which then lead to many arguments over human space travel however as stated before there was an agreement to make the first space travel in 1969. As we continued walking through the planeterium/museum the guide was speaking in croatian as Mrs. Sprljan translated he spoke about the Apollo rocket they had a 3 meter model in their musem he said that it was ten times bigger and that the astronauts were on the very tip of the rocket and how when astronauts returned to earth they ussually landed on Land and not sea leading to some major injures, they needed to be carried out of the spacecraft. After the first guide finished presenting the satelites and spacecrafts we enterd this globe type of object were he presented the stars/the planets. Then we met up with the 2nd guide.

With the second guide we explored mining and the use of electircty against physical power. As a demonstration Where Holly ran in this huge hamster wheel and about 5 boys were ment to stop her. As we moved on we saw how there was a patern of development, how everyday things got simpler and simpler. Then We got to the old car engines and the guide demonstrated how some of the first cars used leavers to get the engine started he also mentioned how most people drove themselves over because they had their car left in 1st gear so it would just drive over them. Then we saw some other intresting things. But finally the mining part came he showed us how they made 12 year old boys work in mines because of the low hight of the mine. And also how they would have mules which would not sea day for their full lives. He introduced the diffrent tools such as pick-axes, shovels. And how the miners needed to work 8 hours a day with the exeption of sunday. He lead us into a artifical mine beneath the museum which was not high at all and most of us needed to crouch. We saw a two meter block of rock missing in part of the wall he explained to us how a miner needs to dig that much within 3 hours and how there was no talking and lunch was 30 minutes. The miners ussually watched for mice running because if they ran that ment danger aslo they carried candels in the mines to see what gasses were down there somtimes its would blow up everything and somtimes it would turn off. As the guide was taking us through the last part of the tour he said that there was water driping from the seelings and how there was dust everywhere and the sound of drills pierced your ears.
