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

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 activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

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.

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.

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

This activity models the necessary balance of creating power and cleaning up its associated waste. Learners participate in a game where they attempt to move forward toward a goal.

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 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

In this activity, learners will build the highest tower they can out of recycled materials.

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 physical activity, two lines of learners link hands and arms to model a beam subject to various loading schemes.

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

In this activity (page 1 of the PDF under SciGirls Activity: Water Slides), learners will whip up some suds with a cup of water and a tablespoon of dish soap until the bubbles are stiff enough to star

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

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

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.

This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.
