Did you know all of what Savannah, Georgia had to offer?
The 8th Grade will be participating in a Georgia Day STEM project. For this project, students will research historical buildings, memorials, and cemeteries right here in Savannah! Students will complete a research paper or PowerPoint presentation on the historical place of their choosing, and then will build a replica of that building.
Phase 1:
Phase 1:
-Research historical buildings and pick 3 of your favorites.
-For each building you choose, you need to answer the following questions:
a) Why did you choose this building?
b) What features do you like best about the building?
c) When was it built?
d) Who was the architect(s) or designer of the building?
e) What materials do you think you would need to build a scale model replica?
f) You should be giving plenty of historical information about this place and what makes it so cool! You want people to want to visit after reading your paper.

Phase 2:
Phase 2:
-After you have narrowed down which historical building you want to do the project on, choose the ONE that you like the most. You must research scholarly websites to gather information on the building. Wikipedia DOES NOT count as a scholarly source.
Option 1:
-Create a 500-800 word research paper on your building or place
-Honors class must do 700-900 words
*This should be roughly 3-4 paragraphs
* You need an Intro, 2-3 body paragraphs, and a Conclusion
Option 2:
-Make a creative PowerPoint and include both facts and images
*Must be at least 10-15 full slides with facts(2-3 bullet-points per slide) and information
-Honors class must do 15-20 full slides
* Must have at least 3 pictures
*Bonus points if you visit your place and take a picture in front of it!
Phase 3:
Phase 3:
-You will need to design and plan to make a scale model replica.
-You will need to design and plan to make a scale model replica.
-You will need to decide which materials you will need to build and decorate your building.
-You will be responsible for providing YOUR OWN supplies.
-These will need to be roughly the size of a posterboard and will be displayed in the front of the school!

Did you know the mathematics and planning it takes to build a bridge?
Students were asked to research at least 3 examples of bridges you could find in the real world. Students then drew 3 examples and then wrote why they liked the bridge design and what they might want to include in their own design.
What is a Truss Bridge?
What is a Truss Bridge?
A truss bridge is a load-bearing structure composed of a series of wooden or metal triangles, known as trusses. Given that a triangle cannot be distorted by stress, a truss gives a stable form capable of supporting considerable external loads over a large span. Trusses are popular for bridge building because they use a relatively small amount of material for the amount of weight they can support. They commonly are used in covered bridges, railroad bridges, and military bridges.

Drafting, reviewing, revising, and approving bridge designs usually takes between four and eight weeks to complete. However, securing approval to begin work can take longer when the site is complex, costs are higher than anticipated, or several companies are asked to submit design proposals.

Road bridges take at least two years to build and are paid with general fund money. Sometimes though, the work can sometimes drag on for more than a decade. On the other hand, pedestrian bridges are much easier to design and construct because they are smaller, require less permitting, and are easier to design.

Site assessment: Before the bridge is shipped from the manufacturing facility, professionals visit the site to check for environmental challenges and make sure that there will be enough space for large trucks and lifting equipment to operate.
Shipping: bridges are usually shipped in sections to the site on large trucks. Cranes or excavators are then used to unload the bridge sections and move them into place.
Assembly: Installation crews are given detailed build sheets that tell them how much each bridge section weighs and how all the sections fit together.
Finishing touches: Before the installation crew leaves the site, they check that the bridge is stable and secure and clean up any debris.
Student Work
Student Work
Students researched, planned, and worked together to design and build a bridge of their own. Using only toothpicks and glue, students worked diligently. Students drew out what they wanted their bridge to look like and used the drawings as a template.
