Unit 6- Redesign and Communicate
In this activity, you will:
-Implement a solution for the Structure
Design for Earthquakes project.
-Cut members, assemble them, and finish
the prototype.
-Always keep safety in mind while building
the prototype.
Always keep safety in mind. Safety if staying out of harm’s way. Follow all of our
specific lab safety rules. Always read and follow lab safety rules. Ask questions when
you do not understand what to do.
While you are working in the lab, use common sense. Make sure to:
- Follow all of the instructions
- Pay close attention to what you are doing at all times
- Keep your work areas clean and tidy at all times
Always read the instructions before beginning the activity.
Carefully follow all of the written and oral directions. If you are in doubt, ask
the teacher for instructions.
Wear eye protection when needed.
Stay focused on your task, especially when you are using tools or machines.
And be aware of the people around you.
If any injuries do happen in the lab, tell your teacher immediately.
You may have the chance to work with tools and equipment that need to be handled
safely.
Wear eye protection when working with sharp tools or machines with moving parts.
When using machines and tools, make sure that you are not wearing any loose
clothing or jewelry, and that your hair is tied back securely.
Keep hands and fingers away from all moving parts.
Handle sharp instruments with extreme care. Always point them away from your
body and cut material away from your body.
Review a machine’s safety rules before you turn it on. Remember to ask your
teacher for help if you are not sure.
After your work is done, turn off any machines that you are using. Clean up your work
area and return all tools to the proper place.
Remember the number one safety rule: Follow the rules and ask questions if you are not
sure what to do.
Safety is staying out of harm’s way.
Always read and follow the lab safety rules.
Ask questions when you do not understand what to do.
In this activity, you will build your prototype courthouse structure. Your structure
may be delicate, so work carefully.
No matter what the design, building a prototype structure includes
several straight-forward steps. The steps are
-Prepare to Build
-Build the Elevations
-Assemble the Elevations
To prepare to build:
-Get your homasote board
and tape your final design
sketch (3-3) to it.
-Place a sheet of wax paper
at least 18 inches long over
the design sketch sheet and
tape down.
Build each elevation of the building in the same way. Always start
with the long exterior columns. And then add the interior columns
and beams.
To build the elevations:
-Place the edge of a wood stick next to the edge of a member on
the design sketch.
To build the elevations:
--To join a beam and a column, create an angled cut. Mark the
angle of the cut on the wood stick. Cut the wood stick at the mark.
To build the elevations:
-Place the wood stick directly
on top of the member on the
design sketch.
-Make sure the angled end of the
wood stick lines up with end of the
member.
To build the elevations:
-At the other end of the member,
mark the angle of the cut on the
wood stick
-Cut the wood stick at the mark
To build the elevations:
-Place the wood stick on top of the member on the design sketch. Check
that the length is correct.
-Tape the wood stick to the wax paper. Do not tape at the joints or
connections.
To build the elevations:
-Repeat the process of marking, cutting, and taping for all of the
members on the elevation.
To build the elevations:
-When all of the members are taped to the wax paper, check that they
line up straight on the members on the design sketch. And make sure
all of the joints will have a snug fit.
To build the elevations:
-Glue the members together. If you are using pins, pin the members
to make the joints tighter.
To build the elevations:
-Set the elevation in a safe place to dry completely.
-After the elevation is dry, remove the tape and pins. Carefully lift the
elevation off the wax paper.
-Repeat this process for each elevation.
To assemble the elevations:
-Place one elevation flat on the wax paper.
To assemble the elevations:
-Put several small beads of glue along one long exterior column.
Carefully line up a second elevation on top of the glue. Pin the
elevations together.
To assemble the elevations:
-Glue and pin the third elevation to the framework.
To assemble the elevations:
-Glue and pin the fourth elevation to the framework.
-To finish the framework, glue and pin the fourth elevation to the first
elevation.
To assemble the elevations:
-Use tape to support the structure while the glue dries.
-Check that the structure has a rectangular shape and is not leaning to
one side.
To assemble the elevations:
-Place glue along the OUTSIDE of the base. **Remember ours should fit on
the inside of the tower**
To assemble the elevations:
-Attach the framework to the foundation plate. (This is the plate that
attaches to the earthquake simulator.)
Pin or tape the framework to
the foundation plate.
To assemble the elevations:
-If needed, add more glue to the foundation plate.
To assemble the elevations:
-After the glue dries, carefully remove the tape and pins.
Congratulations! You have “Implemented a Solution” and
created your very own prototype courthouse structure. You
may now move onto Unit 5 Power Point – “Test and Evaluate”.
