The document discusses the advantages and disadvantages of different materials and construction methods for a duck structure. It can be made from wire which is lightweight but not strong and may rust, or from fabric-covered resin which is stronger, looks better, and adds value but resin may be expensive. Additional steps include decorating by painting, cutting off excess resin, using bolts and nuts to attach parts for easy battery replacement, and including circuit components like a speaker, amplifier, and battery holder.

1. DUCK LAST

2. Wire to the entire structure.

3. The advantages 1.Light weight
2.Format easily
The 1.Not strong.
disadvantages 2.It may be rusty.

4. Fabric Covered structures. Then paint ove
r the resin. Finally, let dry.

5. Advantages
- Stronger
- Good look and value added
- The attractiveness of
the product
Disadvantages - Resin prices may be
expensive

6. Decorated by painting.
Keep the
details Cut off the
excess resin around
structure.

7. Advantage Remove unwanted parts out
it helps
to smooth the surface.
Disadvantage Using color making smell of
chemicals.

8. We use a bolt and nut to stick around body for
four points. By the way, stick bolt and
nut and around the body with the hole that we
drill already. And the remaining glue stick.

9. Advantage : can reassemble for change a
battery.
Disadvantage: quite complicate to assembly.

10. Components in the turtle.
