Building out with garden poles and tape provides students with the opportunity
to experience the same basic physics and engineering phenomena as they
encountered in smaller-scale activities such as Straws
and Pins--Building Out. Students will have an entirely different experience
of these phenomena due to the changes caused by the change of scale. Materials
seem more flimsy, joints seem less secure. This is a good activity to
do near the end of your structure and scale unit, and should be preceded
by building on a smaller scale. As in the smaller scale building-out activities,
students should be given the opportunity to talk about bridges and cantilever
structures that they know.
Building on this scale provides a perfect opportunity to discuss the students'
different experiences of building activities at different scales.
Working with these materials may be very different from other building
that they have done. The students need an initial session where they can
familiarize themselves with these materials, as building out is particularly
difficult on this scale. If this is your students' first use of garden
poles and tape, the first session should aim at simply establishing familiarity
with these materials. In this session, ask the students to build a self-standing
structure using 35 bamboo garden poles and masking tape. Give them the
following rules for construction:
The tape can only be wrapped
twice around any given joint or stick.
When joining sticks in a straight
line, the sticks may only be taped together at two points (at each of
these points, the piece of tape may only be wrapped around twice).
