Rube Goldberg

Session 1

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.

Session 2

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.

Session  3

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.

 

What’s Next

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.

Reflection

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.

Angles investigation

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.

Term 1 Reflection

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.
