A local elementary school group is planning a weekend
hike during which they need to 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 your class
for advice.
DESIGN
CHALLENGE
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
foodstuff.
SPECIFICATIONS
AND CONSTRAINTS
Dehydrate 250 grams of apple slices reducing them
to 20% or less of their initial weight.
You may use only approved materials and tools. In
addition, the drying surface your group uses must
have an area no greater than 144 square inches.
