Exploring Structures
Source Institutions
This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different
Strengthen a Paper Bridge
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp
Designing a Wall
Source Institutions
In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.
Construction Technologies: Construct the Strongest Bridge
Source Institutions
Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge.
Aviary Architect
Source Institutions
In this activity, learners are challenged to design, build and test a birdhouse that will stay cool in the sun.
Kinetic Sculpture
Source Institutions
In this design challenge activity, learners build a tower that’s at least 12 inches high with two or more parts that move (spin, sway, or flap) in the wind.
Bridge the Gap
Source Institutions
Learners work in groups to construct bridges using stale marshmallows and toothpicks.
Tall Tower Challenge
Source Institutions
In this activity, learners explore the design of tall structures such as skyscrapers and telecommunication towers.
High Rise
Source Institutions
In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.
Design a Park
Source Institutions
In this activity, learners are invited to imagine the park of their dreams!
Build a Super Structure
Source Institutions
In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.
Zero-Energy Housing
In this activity, learners investigate passive solar building design with a focus solely on heating.
Balsa Towers
Source Institutions
Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio.
Popsicle Bridge
Source Institutions
In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit
Shaking It!
Source Institutions
In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.
Ride on a Slide: Toys or Tubes Ride Slopes and Angles
Source Institutions
This activity is a hit for family events and all ages—some will finish in 45 minutes; others can go on for hours.
Waterproof that Roof!
Source Institutions
In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.
