Start of Year - Basketball Net STEM Challenge
Grade
7/8 STEM Challenge #1 – Creating a Basketball Net using simple materials
The
Task:
Using the Engineering
Design Process* discussed
in class, your group will create a durable, portable, stable, retractable and aesthetically appealing basketball net, with a maximum height of 6 feet.
*Define task/research/brainstorm-conceptualize/choose your best solution/sketch blueprints/develop your first prototype/test and make further iterations/consider
aesthetics
Materials:
Cardboard, paper, glue, scissors, string, paper plates, plastic cups, elastics,
measuring tapes, straws, duct tape, masking tape, pipe cleaners, plastic
bottles (various sizes up to 2L), velcro
Success
Criteria:
Teamwork – Were all group members are equally
involved in planning and construction? Were all ideas are respected? Was class
time used wisely? Was there collaborative brainstorming (conceptualization)?
Did your group sketch out of blueprints?
Durable – Is it sturdy and well-built. Will it
last a long time or fall apart? Are there any obvious weaknesses in structural
integrity?
Stable – Does it wobble or fall over when shots
are taken or does it rest firmly in place? (Tested using four different,
progressively heavier balls)
Retractable – Does it have four (or more) different
heights it can be raised or lowered to?
Portable – Can it be moved from place to place
(fairly) easily?
Aesthetic – Is it visually appealing? (i.e. –
proportional, nicely put together, colour scheme, straight cuts, etc.)

Create Your Own Basketball Net STEM Challenge – Follow-Up Questions
1.Describe
the TWO biggest challenges your group encountered during this design task.
Explain how you overcame or tried to overcome each one.
2.Describe
one element of your final project design that your group is most proud of.
Explain why you feel this way.
3.If
you could redo this project from the beginning, describe how your approach
would change. Be specific. Describe one or two things your group would have
done differently.
4.After
looking over and testing the designs of other groups, describe one idea or
innovation another group used that especially impressed you. Explain why you
feel this way.
5.On a
scale of 1-5 (least-most), how challenging did your group find this task?
Explain.
6.On a
scale of 1-5 (least-most), how enjoyable did your group find this task?
Explain.
7.Does
your group have any ideas for structuring the task differently, if it were to
be done with other classes in the future?

13.Conceptualization
A.Ability
of an object to collapse into itself or extend outward from itself.
B.The
part of the Engineering Design Process involving planning the size, shape,
materials used and construction procedure for an object.
C.A
thin or thick, often
triangular piece of material, used to reinforce a structure.
D.Ability
of a structure to resist outside forces and remain upright and in position.
E.Easily
movable from one location to another.
F.Define
the problem. Research and brainstorm. Decide on a solution. Create a prototype.
Test and redesign to make iterations. Consider aesthetic improvements.
G.Improved
version of a product
created after
testing and improving.
H.The
average location of an object’s
weight.
Having this lower to the ground tends to make the object more stable.
I.Making
a
structure or parts of a structure stronger.
J.Drawing
or
computer model of a design idea made by an architect or engineer.
K.The
first version of a design idea that is produced.
L.Ability
to
last a long time, despite repeated usage.
M.Part
of the design process that considers the visual appearance of an object or
structure.
