Suggested order for completion of KSBs
by students:
1. Complete Introductory Packet.
2. Students complete KSBs T1, T2, M1, M2 and
S1.
3. The remaining KSBs (S2, S3 and S4) might
then be completed in any order, or groups
could do different ones and share the information
collectively.
Provide each student group with materials
needed to complete the challenge, such as
the materials listed here. (Note: Information
provided to the students about materials in
the Introductory Packet states: "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.")
Additional materials will be necessary to
complete the Knowledge and Skill Builders
(KSBs) that help prepare students for the
design challenge. These materials are listed
within the individual KSBs or in the procedural
suggestions that further describe the KSBs.
SAFETY
CONSIDERATIONS
Safety goggles must be worn for some of the
procedures. In this module, heat is applied,
apples are sliced and wire is cut. Take time
to emphasize the safe use of the cutting instruments
and heat sources you provide. The wire mesh
ends resulting from the cutting of the mesh
can be sharp enough to break skin. Therefore,
make sure that the cut wire mesh is handled
carefully. Check the policy in your district
for students eating foods involved in classroom
activities. We recommend that students not
eat the dried foods they prepare.
