What You Will Do:
In the Drying
by Design module, you will work in a group to:
Understand and investigate possible solutions to a given problem
by an Informed Design Cycle.
Investigate that
problem by completing Knowledge and Skill Builder (KSB)
activities.
Use appropriate
tools and materials to design a solution to the design challenge.
Base your design
and redesign upon scientific and mathematical concepts.
See that your
design meets specifications and constraints.
Collect, plot
and compare test data.
Use mathematical
models, such as graphs and equations, to analyze your data.
Make improvements
to your design based on your data analysis.
Develop and use
a repeatable and reliable method for testing your design.
Propose improvements
based on results of testing your design and related science and
mathematics concepts.
Materials Needed
Your teacher
or group may provide materials and tools. Any materials and tools
provided by your group must be approved in advance by your teacher.
Design Challenge
A local elementary
school group is planning a weekend hike during which they must carry
everything, including their food and clothing. They are concerned
about the heavy load each person will have to carry. Unable to think
of ways to substantially reduce the weight of their backpacks, they
have turned to you for advice. As part of a group, you will design,
construct, and test a dehydrator that dries fruit in as short a
time as possible while maintaining the quality of the foodstuff.
Constraints
Students may use only approved materials and tools.
The drying surface
your team uses must have an area no greater than 144 square inches.
Specifications
Dehydrate 250 grams of apple slices to 20% or less of their initial
weight.
Student Requirements
Students will
be expected to:
See the specification listing above.
Maintain
either a Design Activity
Folio (DAF) or a Design Journal in which you will gather and
record information as you complete the design challenge for this
module.
With your team,
students will be expected to:
Submit a final report that summarizes your work and findings:
Web search results
Hands-on research (factor studies)
Completion of KSBs
Work on design challenge
Methods used to generate the final design solution
Make a professional
oral presentation (using powerpoint slides) to your class that
will:
Justify
your design solution
Use a variety of media
Demonstrate that the solution meets the design challenge
Be assessed on
the quality of your work on MST Knowledge and Skill Builders (KSBs),
your Design Journal or Design Actvity Folio, your Design Report
and your group presentation.
Your teacher
will assess your understanding of the Knowledge and Skill Builders
and evaluate the quality of your Design Activity Folio or Design
Journal, your Design Report and your group's presentation.
