The Challenge
Essential Question:
Work with a fellow engineer to design and build a
How can we make an object with a
model submarine that meets these criteria:
variable density to meet the project
How it works
 Rise and sink due to density changes
 Float for 10 seconds
•
Subs will be built with 2-liter bottles
 Stay at bottom for 10 seconds
•
A filled 75-gallon aquarium will be used

Sample Guiding Questions:
for the ocean
-What materials should we use?
•
The sunken cargo will be magnetized
- How can we remotely change the

Students will work in pairs
•
A variety of materials will be offered, but
Activities along
the way
students may suggest others for their
 Access prior submarine
 Hover at targeted depth for 5 seconds
 Rescue and lift a sunken cargo up to the surface

knowledge
 Develop the essential and
guiding questions
sub’s density?
- How do we maintain the various
densities in our sub?
- How do we equip the sub to pick
up the cargo?
- How can we maneuver the sub?

actual submarine functions and
Global Relevance
Submarines have been engineered to perform
many important tasks for us:
•
Secretly gather intelligence
•
Explore uncharted ocean areas
•
•
find applicable ideas
 Assemble and observe
Cartesian divers :buoyancy and
Maintain peace in wartime settings
•
Rescue/salvage lost objects of value
Recreational cruises
Engineering
Teamwork
variable density
 Brainstorming and planning;
how will we make it work?

Build and test the model
 Make changes and submit for
final launches
A real-life solution to this problem
would require the work of several
types of engineers: Marine,
Mechanical, Electrical, Nuclear,
Military, Systems, Environmental, and
naval architecture.
