Water Filters

In class we were working on creating water filters. Our are top four features were safe for all ages, reusable, efficient and good quality. The were five bottle with different colors the fifth one is really dirty dark brown the first is perfectly clean clear water. Everyone wanted to get a one. The materials we thought about were layered filter filter paper, soybeans and polly glue. The main object in all is a plastic bottle.  Our first design was a clean dry non-toxic baby wipe at the top to catch any particles. Under the baby wipe was around 6 layered filter paper to change the color. Under the filter paper is a mosquito screen folded 5 times to get any other particles. The color we were aiming for was a two. The two had some dirt and very little particles. After it went through there was no particles and was in the middle of a two and a three because of the color. We had a problem with the baby wipe because it overflowed. The baby wipe was still helpful because it took away all the particles.

After are first filter we changed it a little so the color would be lighter. We were still aiming for a two. The design now is the mosquito screen on the top to get all the particles. Under the mosquito screen is  a baby wipe to catch any extra particle. Under the baby wipe is a paper filter to change the color. Under the paper filter is sand and gravel to change the color and catch anymore particles. We had trouble setting up the sand and gravel because sand kept coming out because there was not enough gravel so we had to fix that. After we put it through we decided to put it through again and it turned out to be a three. No particles, but the color was a three. It was dark, but not too dark. It was like a light brown, but a little bit darker.

Since we still needed to get the color of the water to just a two we still needed to work on another filter. At the top there was the mosquito screen for particles. After that was a baby wipe. Under that was a paper filter to change the color that had cotton balls over that was gravel (to change the color and take away any extra particles.) The color for that one was like a two and a half. There was no particles in it. The problem with are filters is that it does not take away all the filters. That would mostly be because the color is tea so it can’t fully take away the color, but it should at least be a little less than a two or a two.

We changed the goal to alka seltzer in water from stamp on paper. After a few times we made it work. It was so exciting. It felt so good I was so relieved. I can’t believe it worked. After 3 goals and 73 takes it worked. It took a long time, but it was wroth it. We were screaming so loud when it completed the course. We were all so happy. It felt like a weight was lifted off our chest. I would show the video, but I don’t have it right now. It took us a while, but we kept trying changed our goals until we got it right. We got really frustrated along the way, but at the end I felt so good. Lexi and Mia did to.

I STILL am working on Rube Goldberg and it got to the end, but the stamp did not hit the paper. It was so annoying. We do not know what went wrong, but we are going to figure it out. I can’t believe it. I think we need something heavier to make it stamp. At east are other problem is not happening anymore. It was still really frustrating. It almost worked. The project keeps on getting better and better. I have a feeling that it is almost done. If it completed it without the stamp pressing down then it will probably finish soon. I just hope it will work soon. I can’t wait to see it finish.

Are Rube Goldberg project still has not worked. We are not exactly sure what is wrong I thin it is because there is not enough force to make the train move or the ball, but I am not exactly sure what the problem is.There might be another reason why it is not working, but I think it because there is not enough force. We need to make some changes to the project because it is not working. We have tried several times and it has not work so are project needs something to change so it can go farther then it has been going. Like I said before there is a problem it might not be what I think it is it might be something different, but we we need figure out the problem first before we make any changes. Other then that once we make a change I think that project will go much farther and maybe go to the end and complete are goal. I am excited to see what happens next.

For my Rube Goldberg Project we decided to change are goal back to stamp on paper. We finished building it, but we have been having some problems. The problem is for our second step the ball that goes the tube might not fully go down or when the ball hits another ball that hits a train when the ball hits that another ball it does not give the ball enough power to make the train move. We have been experiencing both problems. We experience one or the other. We are trying to figure out a way to fix the problem. We are not sure yet how we will exactly fix it,but we are thinking. I am sure that are Rube Goldberg project will go farther then the last time and that soon it will finish all the way through.

In class we are working on a Rube Goldberg project. My group is Lexi Mia and I. Right now we have 8 or 9 steps. We need more steps to make are goal happen which we changed. It is now hot cocoa powder into a cup. We might change it again because we think it might not work. What we have so far is bits of pool noodle cut if half that a small ball goes down, the small ball goes down a skinny tube, that goes to a wrapping paper tube where it hits a marble, the marble hits a ball that goes down a car racer, while going down the car racer the ball hits a train the goes down train tracks, while the ball keeps on going down the car racer when it comes to an end it goes through a tunnel and hits dominoes, while the train comes to a stop and hits jenga blocks, the last jenga block hits a domino that goes under a bridge, and then hits these small skinny wooden blocks. That is all we have so far for are Rube Goldberg project. I think that the hot coco powder in a cup wont work and we will ave to change it. I hope that the hot coco works.

Rube Goldberg 3

In class we are doing a Rube Goldberg project which you have probably seen in my last two posts. It is coming along very nice. My group and  have been working hard on this project. We keep on thinking of good things for this project. We have six steps so far and we need ten, but I know it wont be hard for us to get there. As I said in another post are goal is stamp on paper. We have to think of the right step to make this happen. We don’t expect to make that happen on are first try. We do expect that we will get there. The only problem is we need to find the right object to make the stamp stamp down.I am very proud of are progress so far.

Rube Goldberg 2

In class we are doing a Rube Goldberg project which you have probably have seen in my previous post. Which means you probably know that are goal is stamp on paper. We have been building are project we need to sketch out the blue prints. For everybody in my group (Lexi and Mia) it is easier to first build it which at first we had trouble, but after we found something for a start which is a car racer. We wanted to put something before that so we put a  empty wrapping paper tube there. These are the steps we have so far- a marble at the top of the tube and we push it, it hits another ball that goes down the car racer, while it is going down the car racer it hits a train that goes down a train tracks that comes to a stop, that hits a domino that hits the rest of the dominos, then it goes to a lego board and we have not built farther than that, meanwhile when the ball keeps on going down the car racer it goes through a tunnel then hits dominos. It does not do anything after that so far. That is all we have for are Rube Goldberg project so far.

In class we are working on Rube Goldberg. We got to pick are own partners because are teacher thought since we have to work on it at someones house that we should pick. I choose my two friends Lexi and Mia. First we had to figure out what days we were all free on which was Fridays and Saturdays. Then we had to figure out who’s house we were going to do the project at. We all decided on Mia’s house. After we diced what days we were all free which was Fridays and Saturdays. Then when we met up we decided what are goal would be which was Pasta and a bowl with cheese and sauce pour on to it. While we were building we all realized that our original goal was to hard so we needed to change it. We all agreed on stamp on paper as our goal. We need 8 steps to complete the project. My group and I are excited to see how it turns out. Also a little nervous

This is a video of a Rube Goldberg machine it does not have to be as complicated.
