In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

In this design challenge, learners will engineer a structure and see if it can survive an earthquake they create.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

This simple construction activity teaches the importance of architectural structure. Learners build and test designs for a paper "doghouse" strong enough to hold the weight of a jumbo dog biscuit.

In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

In this activity, learners design, build and test a model suspension bridge for sturdiness and strength.

Play with your food while learning about engineering! Build a spaghetti bridge, then test its strength by piling on the marshmallows, raw spaghetti, raw linguine and coins.

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

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

This activity was designed for blind learners, but all types of learners can explore the process of extrusion used to produce pipes and wires in industry.

In this on site "field trip" activity (located on pages 6-9 of PDF), learners get hands-on experience identifying building materials by playing "Building Bingo".

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge.

In this activity about problem-solving, learners build a house for the Three Little Pigs using twenty straws and two index cards.

Build and test a scale model of a rainforest canopy walkway.

With two stacks of books and a few rolls of pennies, build two kinds of bridges--a beam span and an arch span--and see how much weight each of them can hold.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.
