“Young children are inherently active with strong impulses to investigate, to share with others what they have found out, to construct things, and to create. In other words, a child is a natural engineer.”
-Genalo et al. (2000)

Older Students and Blocks
Models• Physical resemblance
• Functionality
• Tools of theory
Complex systems• Uses of different materials
• Terminology

Bridge Models
Simplified examples of large structures
Simulate construction staging
Encourages thinking about engineering design and practice

Zakim Bridge Discussion
Forces in cables, piers, decking Stiffness of the deck Location/style of cables Advantages/disadvantages

Suspension Bridge Discussion
Forces in the cables, piers, and abutments
Compare to cable-stayed
Span length Cable calculations Failures

Tacoma Narrows Model
![Page 15: Buildable Bridge Models Learning Engineering through Block Play and Model Construction Brian Brenner Julia Carroll Brian Gravel.](https://reader035.fdocuments.net/reader035/viewer/2022062417/551c195e550346a84f8b57e0/html5/thumbnails/15.jpg)
Tacoma Narrows Discussion
Simulates collapse and redesign of Tacoma Narrows bridge
Unstiffened deck comes off with a modest wind
Stiffened deck remains intact

Summary
Blocks encourage science and math development
Block play is usually a child’s first experience with engineering
Block models and hands-on activities provide a tangible way for students to learn about their surroundings
Block models inspire scientific and engineering thought
