Folder Bridge Building Challenge

Manilla Folder Bridge Challenge Part 1

Criteria and Constraints

• Use two manilla folders to make a bridge that can hold up some magazines
• You can only use a foot of tape
• There can not be more than 3 layers on top of each other at once
• There can  not be two parallel structures attached to each other
• Has to be at least 22 inches long, and between two tables

Our design was a big tube of folder taped together, with little folder triangles stuffed inside of it for support. It worked pretty well when we had enough tape to keep it up.

We never got a picture of the the bridge holding up the magazines on it own, but it held for about 3 seconds before collapsing

Manilla Bridge Building Challenge Part 2

We got a picture of the bridge standing on it's own, now with 3 feet of tape. It stood on its own for a really long time, until we took it off.

Centroids on Irregular Objects

Today in engineering we worked on centroids, and hoe to find the center of balance on weird looking objects. I found the centroid on multiple objects but this one was the weirdest looking. I'm not really sure if it is a banana, a croissant, or a shrimp but I found the center of balance on it using the 3 plumbob method.

Marble Drop Challenge

Criteria:
To build a mechanism that moves a marble into a cup once you drop it off of a table. Whoever gets it in from the longest distance wins
Constraints:
2 feet of tape, 14 straws, 3 cups, and a marble. The Marble has to be pushed off of the table and not placed in the cup
Results:
Caleb's group got first place, our group got second, and Tommy's got third.

Mousetrap Cars Challenge

These last few weeks we have been working on mouse trap cars, that had to move without being pushhed or pulled, and are moved by their own power. I was on a team with Jason, and these are our achievements.
------------------------------------------------------------------------------------------------------------
We have 12 achievements
------------------------------------------------------------------------------------------------------------
Brainiac:

• A really long car with small wheels to give more space for the mousetrap to pull
• A short stubby car with big wheels to make it have more traction and be lighter
• A triangle shaped car where the mousetrap hangs and pulls
• Big wheels on the back to have more traction
• A car with a propeller powered by the mousetrap
• A car made of cardboard so its lighter
• Using legos to make it lighter
• A triangle shaped car with a weight on it
• A car with a big tower on it with a weight hanging down

The Race

Our car went really slow and didn't go very far (around 6 feet) but its okay because our car was unique

Competitor

We competed!

Feedback
+ Our car was really unique, we didn't use the mousetrap to power it, only gravity
- We were really slow and didn't go very far
+ Our car looked really cool and was named Big Boy Butchy
- It was pretty much always falling apart

Re-Work
We changed the way the string wrapped around the axle, we changed it to the screw

Game Changer
If I could add a new rule, I would make it so the mousetrap could not be taped down so that there is more of a challenge.

Name it
Old School: Make your car move without the mousetrap powering it

Leave it Cleaner than you found it
We worked outside, and helped the other groups clean up their stuff while they helped us

Design/Build
The design/build process is the process of thinking of potential ideas, prototyping some, building a full scale, and re-iterating it to fix any problems.

Cardboard Canoes

In the the challenge we've been doing for the last few weeks, we had to build a boat out of cardboard and float it in the pool. Daniel, Caleb, Dylan and I formed the team "King Caleb and the Blondies" since we were all blonde besides him. Our original idea since the beginning was to tie a rope to Daniel and have him swim in front, because he was a really good swimmer. Throughout the two weeks we worked together to make designs, put it assemble, and cover the boat completely in cardboard using teamwork and leadership.

We claimed 15 achievements

Design Achievements:

• Design the Problems and Brainstorm Experience

small v-bottom

make a duct tape casing over boat

form cardboard into long cylinders to attach to the sides for balance and flotation

flat on bottom with alot of surface area with smaller sides

• Criteria and Constraints

Constraints

• You may only use Cardboard and Duct Tape for this event.

• All Staples or other foreign material must be removed from your cardboard. If we trash the pool, we will not be invited back for other activities during the year (yes, we have other activities in mind for 2nd semester).

• Cardboard must meet our quality standard and be approved by the instructor (more info to follow)

• Each boat must have a minimum of a 3" tall "sidewall" (no completely flat designs).

• All exposed cardboard must be covered in duct tape (this will reduce cardboard disintigration in the pool).

• Each team will be provided one "versa table" cardboard box piece and three 60yrd rolls of duct tape. Any materials beyond this (likely need more cardboard) need to be resourced by your team.

Implied constraints: 

must be made in time

at least one person must accompany the boat

cannot sink in order to stay in competition

• Surface area: 3000  inches squared, 22.5 square feet can be covered with one roll , 90 square feet can be covered with all of our duct tape, 79% of efficiency 

• Approach:

"project Hippodrome"

Flat bottom, front of the boat is veered up for more hydro dynamics 

we are mixing all of our prototypes in one better design for flotation and speed

• Sketch Ideas
• Prototype Ideas

Build Achievements

• Build It!

   

Test Achievements

• The Fastest -We were first by far
• Pac-Man Kickboards

• Balance Master

Reflection Achievements

• Feedback

+ The boat was very sturdy

- Some of the cardboard got soggy

+We were very fast with Daniel Pulling us

+The size of the boat made it very stable

-The sides were kind of flimsy

-Water got into the boat, but we couldn't find the holes

+The boat never sank, besides a little bit of water getting in

+The ramped front made us more hydrodynamic

-The boat looked kind of silly

-It was hard to get Caleb into it

+It had a sword

• How Long did I go?

Our estimate is about 15 minutes. Personally, I was suprised how long our boat stayed afloat. In the end, it came apart because we crushed it by jumping on it.

• Redesign

Our boat was pretty good, but if I could redesign it I would make stronger sidewalls.

• I also beat Mr. Olsen in the race

Simple Machines

     In engineering class, we went over simple machines, like the lever (first, second, and third class) and the wheel and axle system. These are the equations that went along with them, and some pictures of what we made.

Capstone Project

For the Capstone project, we were supposed to make a dream house for a teacher. We chose to make Mr. Huong's dream house. First we talked to Mr. Huong and found out what he wanted, then we made a prototype in minecraft. Then, we made a foam board house based on what he said he wanted. Here are the Bootleg Bootcamp methods we used:

We used 13 methods over all

For the last few weeks we have been designing a dream house for one of our teachers, Mr. Huong. We made a prototype in Minecraftto Mr. Huong's specifications, and made a foam board model house. I measured the house and drew the lines in the board of where to cut, and John cut it.

This is the finished house from all angles:

During the gallery walk we got 6 post-it notes
