bridgebuilder-game

I found this website you may want to look at on Bridge building. It includes a simulation, downloadable simulators too.  bridgebuilder-game.com

Stage 2

Thank you for your contributions so far everyone. We will start the second stage in the next lesson. In the next stage I want you to reflect on HOW you progressed and how you learnt. For example:
  • trial and error
  • reading the textbook section
  • researching in the library or internet
  • discussing with friends/partners
  • other ways 

Kevin, Carla and Rashid's Straw Bridge Building Plan

An example of a bridge made of straws

In science, our teacher has started teaching us Bridge Designs. So to make the concept clear, he gave us an project to start with the topic. We have experience making straw bridge as we did this last year in Technology with Mr. Phil. Our objective was to make a bridge out of 50 straws & 200 straws and it should be 20 cm long. So he gave us some materials in order to make the bridge:
  • 250 straws
  • Tape
  • Scissor
  • Ruler
Kevin, Carla and I are working very well to make a decent, strong bridge. We have referred to the science book where it explains different kinds of bridge and studied the designs which one is stronger. Till date, we have finished making the 50 straw bridge and we have tested it with some weight. Now we are going to start making the 200 straws bridge and we hope it is stronger than other peoples bridges.

shaahin and feryal's bridge info


special types of bridges are defined according to function. To ensure the strength and durability of bridges and other structures they design.Bridges are structures used by people and vehicles to make crossing areas easier in travel. Engineers build bridges over rivers, lakes, ravines, canyons, railroads, and highways. To build a strong bridge we must be built strong enough to safely support their own weight as well as the weight of the people and vehicles that pass over it. To make a strong bridge some parts should be designed triangular.The bridge should be very strong to hold windstorms, weathering, earthquakes, freezing and thawing.

Madzhid & Sina straw bridge bulding


Our bridge must contain 50 straws, not less, not more. Its length should be exactly 20 cm. Sina and I are working in one group, we are partners in the task that we should accomplish. We need the following equipment:



  • Scissors.

  • 50 straws.

  • ruler.

  • sticky-tape.

  • two objects (to place the bridge between them.
Sina and I are using strong bridge building method which is to build a bridge that absorbs the pressure all over it, so when a heavy object is placed, the pressure distributes on the whole bridge, and the bridge becomes able to hold the heavy object e.g. book, dictionary.
