The Aztecs, one of the greatest Mesoamerican cultures, had all the hallmarks of an advanced civilization. One of their most famous structures, the Templo Mayor, graces the Aztec portion of the John P. McGovern Hall of the Americas. It is a fantastic temple complex, the main religious center of the Aztec capital, and is a feat of architectural genius.
A true-color version of a model Templo Mayor will grace the demonstration shelves of Block Party, HMNS’s new interactive exhibit. And it was built by Moran Ecoteens
The Houston Museum of Natural Science is building a new exhibit called Block Party inspired by the materials used in the construction industry. Curated models of exhibit hall pieces (and visitor-submitted ones) will be on display at the new exhibit. So when the Moran Ecoteens were presented the task of making some of them, an Aztec temple was a popular choice. An image of a temple as inspiration was printed out, and we were ready to build…or so we thought.
John and Connor solve building support problems while constructing the pyramid.
Turns out, not all toy building blocks are useful for this purpose. And after we grabbed enough bricks to make the first two exterior layers of the temple (e.g. the Step Pyramid at Saqqara has six “layers”), it was all we could do to prevent the third level from collapsing under its own weight. (To save bricks, we had only built the outside of each layer, leaving the inside hollow.) Eventually, over the course of several days, I worked out a system of struts, columns, and crossties to hold the layers together; the hollow inside was now full of scaffolding. This allowed us to construct a model with accurate dimensions, while reflecting realistic building techniques. The Aztec temple walls were stone encased in painted plaster; our temple reflects this with rigid supports enclosed by a decorative outside shell.
John stands with his model Aztec pyramid built from plastic blocks.
Our multicolored model is the prototype of a future model of the Templo Mayor. The new one will be made of realistically-colored bricks and have a simpler brick-laying scheme, more similar to the Aztec inspiration. Hopefully, those who see it will appreciate both the spirit of the Aztec culture and the engineering genius that defines the monument.
Cream of the Science Crop: Becoming an Ecoteen
You might be wondering how you can get involved doing cool projects for the museum like the Block Party demos. Here’s some information and application advice directly from Marce Stayer, director of the Ecoteen program.
The Moran Ecoteens are the museum’s teen volunteer program, open to teens ages 14 to 17 and rising ninth grade through rising 11th grade. Teens may apply beginning in December by sending their contact information to Stayer. You’ll be asked to provide your name, street address, a phone number and an email where they can be reached. The first week in January, information packets and applications are sent out to all who apply. Applicants will be asked to include a résumé, a letter of recommendation from a current teacher and an essay on the teen’s favorite area of science. The essay can be related to artifacts in our permanent exhibit halls, but it doesn’t have to be. If you’re interested, work hard to write well! We always receive more applications than slots available for this very competitive program.
Completed applications are due Feb. 28. As applications are turned in, teens are invited to schedule an interview. The process must be complete by the second week in March.
Ecoteens built this model Dimetrodon skull for Block Party, as well.
Selected teens are required to volunteer for one two-week session during the summer. Xplorations summer camp runs on a two-week-on, one-week-off schedule and Ecoteens may choose from these two-week sessions. A new Ecoteen is required to volunteer in the classroom as his or her first assignment. At the end of each week, the teen’s performance is graded by his teacher and turned in to me. If his performance is satisfactory, the Ecoteen may volunteer for additional weeks and have opportunities to work in other areas.
In addition to classroom assignments, Ecoteens are trained to work the touch carts and permanent halls throughout the museum and some are allowed to work in the Special Exhibit halls. They are trained by master docents from the adult volunteer guild for these assignments. They also give science demonstrations to the classes during camp sessions. We have movable demos in Chemistry and Physics, we have a catapult and trebuchet demo, and this past summer, one of the Ecoteens wrote a biology demo called “Microscope Safari” and another created a Morse code demonstration.
Lastly, the Ecoteens help the Youth Education department by working on various crafts that are used during camp — wands and hats for Wizard Academy, belts for Star Warriors Academy, plaster footprints, teeth and claws for the various paleo classes, giant T. rex footprint cut-outs, complete skeletons made out of paper bones, and whatever the classes need. We also write and perform the CSI crime scene on Fridays and put on the Wizard Academy Triwizard tournament. In short, we jump in wherever we are needed!
If this sounds like something you’re interested in, now’s the time to ask for an application so you can get started and be competitive. Best of luck!
