 * Rube Goldberg Machine Plan **

**Group Members:** Samantha,Bethany


 * Task: ** Break an egg

**Materials that you think you will need:**lever, marble roles, boards, domenioes, pully, egg, hammer, little cup, table, marble, toy gears.

**What simple machines do you think you will use?** pulley, inclined plain, lever.


 * Questions that you have: **

Great!
 * Day One: **
 * We started planning our machine. **


 * Day Two: **

Did your material list change on Day 2? Are you using the simple machines that you thought you would? How do you plan to break the egg?

That day we started forming the pulley and also started setting up the domenioes that will fall one on top of another that will make another marble that will role into the cup and lower the hammer to crush the egg.

What progress did you make on day 3? What has been the hardest part?
 * Day Three: **

On day 3 we spent alot of time working on tying the hammer to the rope on the pulley. The hardest part was to figure out how the hammer was going to be tyed to the thin string.

You made some changes on Day 4. What changes did you make and why did you make these changes? (If you need help with tying knots, please ask!) I would like you to name your machine too. Do you have any ideas? That day we set up the domineos on the bench because there was another group right next to us. We also said no to the water and we need to add more marble roles. the name of our invention is __The Egg and the Hammer Meet Again.__
 * Day Fou****r:**

Wow! Your invention made so many changes on Day 6! It is really exciting. I think that you are really close to getting it to work without any human intervention. You just need to make a few minor changes. How many, and what simple machines are you using? How many steps do you have? I would like you to start writing a rough draft of the steps that your machine has. Good work! That day we made a new design and today we are going to test it and make some little changes.When we changed our design we put in new simple machines. Like, a pully,lever and a inclined plane
 * Day Five and Day Six**
 * Day Seven:**

Nice job yesterday! Your invention was well built and you did well presenting under pressure! 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? Thanks! Our machine had 3 simple machines in it. There was the, pully, lever, and an inclined plane. We had 5 steps. I'll list them, Step 1: push the hammer down on domenieos. Step 2: the domenieos will push ballbearing down marble role. Step 3: the ballbearing will role down and push blue marble. Step 4: the blue marble will role and hit the can. Step 5: the can will fall and make the cards crush the egg. The hardest part was making the cards stay in the air. it took us like the first week and a half to figure it out. the funnest part was when we crushed the egg. Although we had to push the can over. Making it work without us doing anything.
