Popsicle stick bridge/ Seismograph

Title Page Project Explanation - For this project, i had to create a bridge out out of popsicle sticks that could support some weights. I also had to make a seismograph that could record some movement from a small movement to a big one.
Technological Concepts - The technological concepts in the popsicle stick bridge were compression, tension, torsion, and shear. Compression squeezes them  together, tension pulls them apart, torsion twists the material, and a shear causes parts of the bridge to slide past one another in opposite directions. The technological concept for the seismograph is the Richter Scale, which measures the magnitude or strength of an earthquake.
Learning Goals - The goals for this assignment were to create a stable bridge that would look good and support as much weight as possible. We wanted to use as many popsicle sticks in the bridge as we could so that it could give it the most strength possible. The goal for the seismograph was to make something that could record the movements and be able to differentiate between the forces. 
Description - For our bridge, we had to use 120 popsicle sticks or less and create a unique design that would be able to hold as much weight as possible being put on top without it breaking.

Description - For our seismograph, we hung a pencil on a hanger from wood and placed a piece of paper under it to record the movement. We also glued on a weight to the pencil so that it would be heavier so that the pencil could be seen on the paper so that it would record the movements.

Positive Feedback - Our bridge ended up looking really cool and it performed well, too.
Redesign - i would probably do the same thing for the bridge but i would design a different top and bottom. for the seismograph i would have tried a completely different design because the one that we did didn't work very well
Technological Resources - Every thing we used in both projects were found in the room. For the bridge we had 120 popsicle sticks and glue to use. For the seismograph we used scrap pieces of wood, tape, a hanger, a pencil, paper, and a weight.
Biggest Challenge - The hardest part of the bridge was getting everything to lie up so that the design worked the way that it was suppose to.;The biggest challenge was getting the pencil in the seismograph under control so that it would actually make a mark on the paper and record the movements. When it was attached to the string, it just swung around randomly, but when we used the hanger, it was more stiff so it had better control when it was being shaken.
What I Learned - In this assignment, I learned that it is very difficult to make a seismograph and there are unexpected complications in every project.
