Our Team Leader's favorite quote:
We will try our best and we will succeed!
Hard work works!Why we think we should win:
We think we should win because we worked really hard on this machine. We don't have any background in building a machine complicated as such. We also don't have almost any physics background.
Our home room teacher came to our class one day and asked who wants to take part in the building of a Rube Goldberg Machine. 8 of us raised their hands. We did so without even knowing what it is about or any details. slowly but surely we realized what we have to do. We started thinking about the "stations" and the connectors between each station. we worked on this machine for many days and are really proud of the outcome. Our principal is very supportive of our initiative and we hope to continue participating in the Rube Goldberg competition every year. We think we should win because we learnt a lot not only in physics, we also developed our creativity skills. we definitely think more outside the box and its easier for us to think about solutions. another important thing is that we became closer as a group, we got to know each other and our teacher as well. Suggestion for next year's challenge:
send an email
pour a cup of water
put glasses on
Our idea was to show quiet a complex route in order to achieve the final task which is to insert a coin into a piggy bank. So what we thought was that since we have to finish with a coin, we might as well start with one.
In our RGM we incorporate different materials and elements such as pipes, tubes, marbles, paper cups, a variety of balls, tracks, buckets and more.
In order to get the needed materials, we did few things. We asked the parents of our class if they have things that might help us like springs, tubes, sticks and more. We also looked through out the school to find materials, asked the janitor and some of the materials were bought of course.
Our Step List
1. we insert a coin to a small track.
2. At the end of the track the coin falls into a cup.
3. the cup pull a barrier that releases a car.
4. the car rolls and pushes a marble.
5. the marble falls onto an Archimedes screw which leads the marble causing it the push a small barrier.
6. the barrier that falls drags with it a chain of beads.
7. the beads fall in a slalom shape. they pull another barrier.
8. this barrier releases the marbles to roll in a giant spiral.
9. at the end of the spiral, the marbles push a cup that pulls a string in order to allow the car to roll.
10. the car pops up a balloon filled with water.
11. water drips into 6 test tubes and turn the water to be colorful.
12. the water in the tubes release a bucket which drops many colorful balls.
13. these balls push a string to allow the ball on top to roll.
14. the ball pushes a ping pong. it goes down a stairs made of cards and then pushes the dominos.
15. the dominos pull a string which causes a bottle to fall and the water goes down into the colorful bucket.
16. the colorful bucket slowly goes down and causes a rail to fall.
17. A ball falls down from the rail to the orange bucket.
18. the orange bucket releases a barrier allowing the paper towel to roll into a tower of cups.
19. the cups fall and pull a string that releases a metal marble in a small yellow track to roll.
20. the marble then releases the barrier that holds the coin .
21. the coin rolls into the piggy bank.
