With the help of a professional and some volunteers the SciGirls purchase materials, take measurements, and build a chicken coop for Growhouse. The SciGirls also set up the chicken coop so it has everything the chickens will need to survive.

The SciGirls are going to build a new chicken coop for a local community garden but first they need to learn all they can about chickens and what they need to be healthy. The SciGirls also learn what the Growhouse is looking for in their chicken coop.

Now that the SciGirls have learned about chickens they create a plan and build a prototype for the chicken coop. The coop must be built to scale so the Growhouse staff can decide if it's what they are looking for.

After researching, planning, and building the SciGirls are ready to unveil their completed chicken coop to the Growhouse staff and community members.

Thinkport | Solving Linear Equations

Learn how an architect uses scale drawing and other mathematics to represent floor plans of buildings under construction in this video from MPT. In the accompanying classroom activity, students watch the video and then create a scale drawing of a rectangular area in or near the classroom, choosing an appropriate scale and explaining their strategies for calculating scaled measurements. In the process, they are exposed to an algebraic strategy for calculating dimensions to scale. To get the most from the lesson, students should have experience solving equations of the form ax = b. For a longer self-paced student tutorial using this media, see "Solving Linear Equations" on Thinkport from Maryland Public Television.

Learn about the role of math in architecture in this media gallery from MPT. In the accompanying classroom activity, students design a triangular roof and find equations for the lines that include the sides of the triangle. They verify that the point at which the two lines intersect satisfy both equations. To get the most from the lesson, students should be comfortable finding the equation of a line from two points and graphing linear equations, and they should be familiar with slope and y-intercept. For a longer self-paced student tutorial using this media, see "Systems of Equations" on Thinkport from Maryland Public Television.

In this video segment adapted from ZOOM, cast members construct simple structures based on the light-but-strong design of the geodesic dome using gumdrops and toothpicks. These gumdrop domes help demonstrate that some shapes, like triangles, are inherently strong while others, like squares, are comparatively weak.

Himalayan Megaquake | Building Earthquake-Resistant Homes

Learn how engineering and construction technologies can help buildings survive earthquakes, in this video from NOVA: Himalayan Megaquake. A wooden frame hidden within the brickwork of an old palace in Nepal provides flexibility and tensile strength, which helped the building withstand a recent earthquake. Taking inspiration from this kind of timber lacing, engineers developed a similar system using local materials available in villages. Instead of using wood beams, villagers form bands using wire cages filled with rocks and mud. These features, called gabion bands, help village homes remain standing when an earthquake hits.
