Rube Goldberg parts
Today we made Rube Goldbergs. The aim was to make a peice of paper go in the bin and you had to have at least three parts. We only had two hours. First the teachers paired us up in groups of three that had one person from each class in it. Then they gave each group an A3 peice of paper to draw their plan on and fifteen minutes to plan. When the fifteen minutes was up we started to build our rube goldbergs. We nearly COMPLETELY changed out first plan. In my group’s rube golberg we used a golfball, a small yoghurt cup, a pipe, tape, string, a peice of paper and a wooden train track. What happens is the golf ball rolls down the train track into a tube and then knocks the cup with paper in it off into the bin.
Today we started learning about the parts of a rube goldberg. This session we started pulleys. We got a bendable wire, some string, a plastic thing that the string goes on, a yoghurt cup and marbles. First we got the piece that the string goes on (it has a hole in the middle) and put it through the bendable wire. Then we bended the bendable wire into what looked like a clothes hanger. Then we get the yoghurt cup and put the bendable wire through it to make a handle. Next we tied one end of the string onto the handle and put the other half over the piece that holds he string. To finish it, we put some marbles into the yoghurt cup. Here is a picture of the finished product.
Today we made parts of a rube goldberg in lego. I did a kind of lever. How you start it is you knock a dominoe which pulls a piece out which enables another piece to swing around and hit the ball which makes the ball go down the ramp. I didn’t get it finished though.
This session we worked on knex. My group and I made a dump truck. This is what it looks like.
This session we were supposed to put all our Rube goldberg parts together but I didn’t have time because I needed to finish building my lego. This is what it looks like now.
This session we began planning our Rube Goldberg machines. First we were placed into groups of three. Next we came up with what we want our Rube Goldberg machine to do. Our machine will make a lolly go in someones hand. Yummy. Then we started to plan. My group planned about what materials and simple machines and objects that we might use. We didn’t get much down though because we only had five minutes.
This session we began planning in our design books. I planned about the materials, the simple machines and the objects.
This session my group and I drew a plan of our Rube Goldberg. Then we wrote what will happen and label the stuff we are using. Then we got a little more specific and wrote what the parts of the Rube Goldberg will be made out of. Next we drew and labeled a picture of each part. After that we decided who will bring what. I have to bring a see saw, wood and
This session we didn’t do much. We changed our plan a little bit and started to build a pulley.
This session we finished building the pulley and we built something to hold it up. We haven’t got a ramp yet so we used a tube for the start. A marble goes down the tube and hits some dominoes. The dominoes fall into one end of the pulley and the other end goes up and hits a lever (a see saw). This session was very succesful.
This session we got our Rube Goldberg to work! One of the teachers drilled a hole in one end of the lever so that when the pulley comes up and hits one end of the lever the other end goes down and knocks the marble out of the hole which knocks a lolly off a table into someones hand. This is a video of our attempts, pictures, and our success. Our rube goldberg worked on attempt 10.
We had two attempt 11’s beause the first one didn’t even hit the dominoes. We are lucky that we have finished our rube goldberg so early because now we can add more parts to it.
This session we didn’t do much except for re-design. We had a few attempts but none worked.
Session 8 (the last session
This session we were very successful. We got it to work two out of three times, two times in a row. The reason our machine doesn’t work 100% of the time is because the see saw doesn’t egect the marble fast enough. This is a video of what we have done throughout the rube goldberg unit.
