Post navigation Straws and tape might not be very strong on their own, but it was amazing to see how sturdy they could be when they were combined together just so! Want More? So the kids went back to work! They added more straw supports to distribute the weight and evened out the base to make the structure more steady. This first draft held the cup when it was empty but toppled over when it was filled with pennies. The challenge was to build a bridge that would hold a cup of 100 pennies without falling over. Once the kids had a solid understanding of how bridges work, they were eager to jump in and start building their own miniature versions with straws, scissors and tape. We chatted about how each design evenly distributes loads through specific points using a combination of pulling forces (tension) and pushing forces (compression).įor instance, in a cable stay bridge, cables direct the weight of the traffic and the bridge itself onto the support beams in the middle (called piers) and the supports on either end (called the abutments). ![]() (The book is written for grades 2 to 6, so I needed to be selective to keep it age-appropriate.)Īs we read, we kept track of what we learned by adding to a simple anchor chart showing the five bridges we were focusing on: This post contains an Amazon affiliate link.īefore diving into our engineering project, I wanted to introduce the kids to some bridge basics so I pulled out a copy of Bridges! Amazing Structuresand shared the major highlights. What will your class come up with!? Create more amazing STEM projects with our Epic STEM bundle! With just a few simple supplies, they can design a load bearing bridge just like the ones they drive across in cars! Conclusionīridge Constructor Free is overall a fun and challenging game which definitely gets addictive the more you play it.Building straw bridges is a fun way to strengthen kids’ science, technology, engineering and math (STEM) skills. The most annoying thing however about Bridge Constructor Free is that it does seem to crash a lot. The graphics and sound in Bridge Constructor Free are basic but this is forgiven because of the addictive gameplay which pushes you to the limit in finding a way of constructing durable bridges that can withstand any load. Basic graphics and sound but addictive gameplay There are two different stress levels: car and truck and a high score award per level. You have four different building materials to work with: wood, steel, steel cable, and concrete piles which display their stress load tolerance so you know which ones to choose depending on the challenge. Beyond this, you can even unlock hidden worlds and levels. The scenery and backdrops are similar however ranging from City and Canyons to Beach, Mountains and Rolling Hills. However, it's more challenging than Bridge Constructor Playground because there are budget and material constraints. Unlike Bridge Constructor Playground which you can play against a friend, Bridge Constructor Free only has a single player mode. As you progress you win badges, with five badges in all to collect, which becomes increasingly difficult as the loads increase.\n It's tougher though because you have a fixed budget and limit on building materials which means you have to be really prudent with how you build your bridges. Unlike the sequel however, Bridge Constructor Free is tougher and it doesn't have an extensive tutorial although it's not too hard to figure out how to play. Single and multiplayer modesĪs mentioned, Bridge Constructor is the original game that inspired Bridge Constructor Playground. They are then exposed to stress tests to see whether they can support the weight of the cars and trucks that drive across them. ![]() There are 30 levels requiring you to build bridges over various obstacles such as deep valleys, canals and rivers. Bridge Constructor is very similar to the sequel. It's the original game that inspired Bridge Constructor Playground and is the free version of Bridge Constructor. ![]() Softonic review Fun and addictive bridge building gameīridge Constructor Free is a fun puzzle game where the aim is to build bridges.
