Space Station components.
- As a class, use Figures 1 and 2 to decide upon the point or points that
will represent the "design / layout center" of your Space Station
Outline. Draw an appropriate vertical and/or horizontal line through the point(s).
- Each team should highlight and identify your Space Station components on
Figure 1. Check with the neighboring team(s) to make sure there is no duplication
of ISS components. Make a sketch of your team's components.
- Use a Team Table of ISS Components provided by the teacher (or if time,
make your own team table).
- Determine how many times the drawing shown in Figure 1 will "fit into"
the actual size of the International Space Station. This will give you a scale
ratio such as 1000 to 1.
- Measure each dimension of your assigned ISS components on Figure 1. Multiply
dimensions by the scale determined in step 5. Record the diagram measurements
and calculated ISS dimensions in your table (if needed, see Metric Conversions.)
- When all teams have finished their calculations, prepare to lay out your
outline of the ISS. Consult with the other teams to make sure your "design
decisions" (component distances from reference points, etc.) meet their
design needs and expectations.
Part 2 (approx. 2 hours) - Outdoor Layout of ISS Perimeter - Take your labeled sketch and all needed materials to the field to lay out
the perimeters of your team's ISS components.
- First, position the Truss Midpoint in the middle of the field to make sure
the finished outline will fit into the space available. Put down marker cones
for the truss line and a vertical line which will run through the center of
the ISS components. These two center lines will be perpendicular to each other.
Place 4 additional cones to represent the outer points of the outer solar
panels. Verify that all the cones are correctly aligned and the right distance
from each other (see Figure 2).
- Perform your ISS layout assignments.
- Once outlines are completed, label all components.
- Be prepared to give a guided tour of your team's ISS components.
