Today we did Lego
We had to get all different little things when we were building here is a video of all the steps we did building the se saw.
Today we did connects we made a well it was very hard to build but we got through all of the hard steps. First we built the frame then we built the bit for the string to hang on to then we built the lever for it to go up and down then we built the bit were you can put things in. That was my first time building a proper connect structure.
We made pulleys today first we got a cotton rill, wire, yoghurt cup and string. we put the wire through the cotton rill and tied it p with wire then put little holes in the yoghurt cup and put wire through that. Put the string around it and there was out easy pulley we made two other one they were harder to make. I learnt haw to make easy and hard pulleys with one cotton rill two cotton rills and four cotton rills. The one with the four cotton rills did not work because the string got tangled around the rills so that one did not work but the others did. I want to know how many cotton rills you could make one pulley have. I liked doing pulleys.
Putting them all together
Went we out them all together we had to make another pulley but when we tried to have the pulley to drop a marble into the Lego funnel it did not work because the marble did not land in the right place. So then we tired to put string around the windmill that Ashleigh’s group made but that didn’t work either.
What is a Robot
A robot is a complicated machine that can do hard or simple tasks without anything like food or water to survive it is just like a human but we need food and water.
What is needed for a robot to work
A robot needs skill knowledge because robots don’t have a brain and creativity.
What is a program.
A program is a thing that programs a robot to do things.
Why do you think people invented robots.
To help people that cant do things that other people can do.
Today we did a rube Goldberg thing for our rube Goldberg project this term. Our aim was to put a piece of paper in the bin. We were told to bring in thing like balls and tracks to build it. First we got into little groups of three then we did a plan our first idea was that we could take a photo on a computer. We tried that but it did not work coze the object that you have to hit it didn’t get hit hard enough so it did not take a pitcher. Then we tried to have a se saw thing where one ball goes in and on the other side a ball would come out but when we tied it and the ball on the other side did no come out. So then we did this someone nocks the ball on to a box then it falls of on to the key board and types so letters then falls down a tube that has a piece of paper on the end that falls into the bin.
Today we did our rube Goldberg projects first we went into our groups then we started getting our ideas for what we could do for it we thought of ringing a bell. First on our deigns the ball went down the incline plane up then down on the see-saw then the ball would fall on to the lever and knocks another ball that goes down the lever knock some dominoes then a ball falls into the pulley ringing the bell. Here is a picture of my deign.
First we had to make the ramp then we put the see-saw at the other end but that didn’t get enough speed to get to the other side. So then we put the see-saw first and then the ramp and that worked. So then we added in some levers the first time it worked because the marble went down the see-saw up the ramp and pushed the lever and the marble went down. But the next time it didn’t work. Here are some pictures.
Today we did our rube Goldberg projects. First we had to see if everything still work then we had to make a new paper ramp because the other one was broken so first we tried to make the ramp with normal paper. But that was to thin so then we used a thicker paper that worked. Here is a photo were is was broken.
We also made a structure so it can hold the pulley that we made. We also got a pipe so the marble goes into the pulley straight away with out missing. The structure made the pipes more balanced. The pulley bit has not worked yet so when we get a chance to we will probably work on this the most. Here are two pictures of the structure and the pipes.
We are going to work on the end where the pulley is and the pipes because that bit is the only bit that does not work on out Rube Goldberg machine.
This is my rube Goldberg reflection. I liked doing our deigns because we got to experiment on what we could do in our deigns. We chose to ring a bell because it was a easy task to do and not to complicated to do. What we need it to go to ring the bell. First we put the incline plane to make it have some momentum at the start then another incline plane to get up. We put the lever there so it goes down into the tube. We put the pulley there so it could hit the bell straight away and so we had another simple machine. The two things on our Rube Goldberg machine that did not work were the lever bit was because it some times did not get pushed enough so the other marble did not go down the tube. The other bit were it did not work is where the marble falls out into the pulley. Some times it did not work because the tube and the funnel bit were not inline with the pulley. The other times it does not work is because the marbles are not heavy enough so you had to put three to five marbles in. So in the end sometimes it worked and sometimes it didn’t work. I learnt that you have to keep working hard at it and sometimes it doesn’t all way work.
Today in maths we used random angles and angles on a line they were very, different angles that came up. Angles on a line was were you had a red and blue side you would cover up the answers. Then try and work out the answer and see if you were close. Random answers were when you cover up the answer, then you click a button and a random angle come up and you try to work out how many degrees it was. Here are some photos of the angles.
Some of my answer were very close but one wasn’t so close I got most of them right.
This term 1 was amazing, as well as learning a lot I had so much fun.The things I liked the most, were having maths with Mrs Bartlett, trying different instruments like the Clarinet, Flute, Trombone and Trumpet for allegro, I liked how different all of the instruments were and learning lots of songs. In design I liked doing roller coaster,it was awesome with lots creativity as well and I learnt what is the difference with a roller coaster and a marble roller. Sport was lots of awesome games and more I liked how we could chose a sport for every Thursday. I am really looking forward to our rube Goldberg machines, as well.I am really ready for the next amazing term ahead.
Today we tested our cars to see what surfaces it worked best on. I did not think that my car would work on the oval very well because it only went 4.90cm I think it was because the oval had lots of grass on it and it was not very even with grass bits everywhere. So it is not easy to travel on but as well the cars wheels sunk into the grass a bit like when my car wheels went in to the grass like concrete so it was hard for the car to get going. So on the other surfaces it worked way better because it was easier for my car to travel, so the tennis court it went 6.00m. I think because it was easy for the car to get across the ground because it was even. But I think it worked better on the carpet in the classroom because it was a little bit bumpy but smooth to so I think that’s why it went the furthest. We used a bar graph to record how far our cars went.
today we did craft with Anatoli we did wood cars with drivers. the tools we used were hammer plyers and a copping saw. we started with choosing a car there were all different cars I chose a Maserati first we had to trace it then we got the copping saw and started to cut it had to be 3 fingers high it was harder to cut the angles. after we sanded it so it was nice and smoth other wise it would be to rough. when you were sawing you had to make shore that you were all way cutting down not side ways and defiantly not up towards you.
Anatoli put on the wheels and the motor there was our car now we had to make a driver. there were all different drivers I chose a elephant driver I thought it wold be hard to cut out the round bits. but I was acshowly very easy to cut I started to put some detail on my elephant it looks much better now next we got two screws a piece of wood that is thin and a hammer and nailed it on to the wood it leased I did not do the nails wonky other wise I would have to get the plyers and get the nail out then we put our driver on and they got there listens we tested then out mine worked. I loved it and I had a awesome experience.
