Test and improve different bridges with the whole class on the basis of work cards and challenging assignments. There is no cookbook included with this set. Students have to make the construction themselves on the basis of some tips and photos.
Very suitable for STEM education, including an English teacher's manual. And work cards for the students in English.
Polydron bridges class set
Unlock the secrets of building bridges with this Polydron bridge set. Beginning engineers or designers can build and test different types of bridge designs.
In this set some of the most recognizable and world-famous bridge constructions. Includes the Truss, Suspension, Cantilever, Cable and Bascule Bridge.
The parts are delivered in a sturdy box so that everything stays together. There are also 12 work cards where it is explained what each part can be used for. These work cards are supplied in English and Dutch. So also suitable for bilingual education. The set consists of 322 parts.
There is a work map of each bridge where hints are given on the basis of a few photos and instructions on how to make a bridge. It's not a cookbook recipe. They have to think about how the bridges should be put together.
It also explains why a bridge is strong or what the advantages of these bridges are. At the end of the work card is an extension where b.v. is a challenge for which the children have to come up with a solution.
The 8 standard bridges are:
Truss bridge (Pratt-Truss bridge)
Truss bridge (Howe-Truss bridge)
Truss bridge (Warren-Truss bridge)
Overhead girder bridge
Cantilever bridge
Cable-stayed bridge
Suspension bridge
Drawbridge
The children can build these 8 bridges in groups at the same time, there is enough material in them to build all 8 and leave them standing.
There are also work cards with advanced topics. Parts of the 8 standard bridges must be used for this.
Advanced topics include:
Great Catilever Bridge: With a middle section, the challenge here is to make the bridge as long as possible with different pieces of bridge deck and towers.
Longer Cable-stayed bridge: Make a longer cable-stayed bridge with the help of paperclips and rope, but do you also have to make the pillar feet higher?
Making suspension bridges longer: How long can I make a suspension bridge and also strong. How do the cables that hold the bridge work?
Bascule bridges: This bridge works with a counterweight, make a sturdy framework to have enough force to lift a road surface.
Swing bridges: How long can you make both sides of the bridge if they remain symmetrical. And what happens if both are not symmetrical?
Pillar bases: The Pillar foot is the foundation of the bridge. In what ways can you use this pillar base.
This set is ideal for STEM education. STEM education is Science, Technology, Engineering and Mathematics. Translated into Dutch: Science, Technology, Architecture and Mathematics. With Voice toys, children are introduced to Inquiry-based and Design-based learning.
They can discover and develop their technical skills and knowledge in a playful way through b.v. this bridge set. This includes stimulating critical thinking, collaboration and general learning and thinking skills.

Not suitable for children aged 0 - 3 years due to small parts such as strings in this set.
BPA free: This toy is BPA free and 100% recyclable.
Easy to clean, the plastic parts can even be put in the dishwasher up to 70°C.
