Clapper Rail Nest Engineering Design Challenge: Student Worksheet

0 / 25 / 50
Capacity: The number of eggs held inside nest / 0-1 / 2-3 / More than 3
Replication of real environment:
Nesting materials / No real environment materials used in design / Some real environment materials used in design. / All real environment materials used in design
Cost: Nesting materials / The cost of materials to make nest is over $60 / The cost of materials to make nest is over $30 and under $60 / The cost of materials to make nest is $30 or less
Preservation: Temperature stabilization after 5 minutes
(Ability to hold heat) / Temperature inside nest decreased 10°F or more in 5 minutes / Temperature inside nest decreased between
5-9°F in 5 minutes / Temperature inside nest stayed constant or decreased less than
1-4°F in 5 minutes
Protection: Egg Drop test
*note: only testing 2 eggs / All eggs are broken after egg drop test from 20.5 cm (10 in) / Only 1 egg is broken after egg-drop test from 51 cm (20 in) / None of eggs are broken after egg drop test from 76 cm (30 in)
