Group+2+(Matthew+and+Sesylia)


 * Rube Goldberg Machine Plan **

**Group Members:** Matthew, sesylia


 * Task: ** Breake an egg

**Materials that you think you will need:**marbles, card board, tape, dominose, hammer, toobes, marble roll

**What simple machines do you think you will use?**pully, incline plane, wedge, weel and axle


 * Questions that you have: **


 * Day One: **

ou This looks like a lot of fun. What simple machines are you using right now? Are you going to add any others? How do you plan to break the egg? (When you "practice" you could use something like a bean bag, or a ball, or a crumbled piece of paper instead of an egg. Save your egg for the final!) We are going to use a bean bag Your invention changed a lot on Day 3. Are you changing the location? Are you still going to use the pulley that is pictured in Day 1? No we are not going to use the pully
 * Day Two: **
 * Day Three: **

**Day Four**: It has been fun to watch your machine change. Do you still have a pulley? A wedge? Did you make any changes to your plan at the end of last week? (I have a video of the marble pushing the water bottle--it wouldn't post.) We are not going to use the pulley or wedge. We did make changes, we moved are location.  Wow! You two are really close to getting your machine to work. I think that now you can work on making minor changes to that no human intervention is needed. Can you start thinking of a name for your invention? Also--please begin to write a rough draft of the steps that you will turn in on Thursday. How many, and what, simple machines are in your invention? How many steps do you have? We have 6 steps we all most have 7 steps we just need the egg. We have wheel and axle and an inclined plane.
 * Day Five and Day Six **

 Your machine changed a lot at the last second yesterday. Was that a good idea? What simple machines were in your invention? Can you list the steps? What was the hardest part of this project? What was the funnest part of this project? What would you do differently next time? The hardest part was geting the board to stay in the right place. The funnest part was when the marble hit the big dominos. We only used 3 simple machines we used are a inclinedplane, a weel & axle, and a lever. We will not use an egg.
