Week 1 Project
Escher

Project Preference
''Your class was given a list of projects to choose from. Please list the three projects you want to work on, from highest to lowest.''

Problem Statement
''In one or two sentences, describe the project that your group will be working on. Identify what CDIO phase (Conceive, Design, Implement, or Operate) your group will complete in this project cycle.''

Project Plan
Briefly describe your group's plan for the next 4 weeks, including major tasks that will be completed each week.

Week 1 Narrative
My task for Week 1 was to play with the plastic tubing and see what shapes constricted the water and which ones let it flow the fastest. I will then start to think about what design our group wants to use for our water table project.This sort of has become my week 2. For week 1 I was helping to look at designs and was helping with the building of the prototypes. Our prototypes were built out of scrap wood pieces and cardboard piece on the top. Me and Yuchine were evaluating our design and came to the conclusion that our design does not do a good job showing this effect. Sonney's design still has to be finished so we will see what happens. I think that going to a marble instead of water may be easier.

Week 2 Narrative
The marbles were put into the tubing and it was discovered that they were to big to be able to fit through the tubing. The next step was to try the big tubing with smaller marbles. This worked but the problem was that the small marbles went through the tubing so fast that you could not see them go through. The conclusion was that using a channel and the marbles would work better.

Week 3 Narrative
A prototype was built using channels made out electrical tape to keep the marbles moving in a straight line. It was tested to show that it would work. The next step was to focus on the camera angles to make the illusion work properly. Creating a power point and a presentation to explain and demonstrate this illusion and how it works.

Week 4 Narrative


The marbles were run down the track and timed in seconds. There was an average taken over 5 trails. The marbles were ran down the track with painters tape over the track, 100 grit sand paper over the track and 220 grit sand paper. They were timed in seconds and an average taken over 5 trails. The times were all compared to the track with nothing on it. The 100 grit sandpaper slowed the marble down the most of all the different things that were tried. This is because the 100 grit sandpaper had the most friction with the board and the marble. The small marble was the only one that was truly effected by the 100 grit sandpaper. The 100 grit sandpaper slowed it down about 1 second and 5 one hundredths. The two big marbles had a few hundredths of a second slower time.
