I have found over the years that putting together these
simple paper models generates high interest with many (but not all)
middle school students. I usually have them complete one model in
class, some students have no idea to go about such a project and
without immediate help would give up in frustration. I then allow
students to construct other models at home for additional credit.
Models
available (when the site was last checked):
To provide a more concrete concept of the
spacecraft they read about.
To increase interest in information sent back by
spacecraft (It gives students a kind of "proprietary" interest in the
spacecraft of which they have built models, and their missions.)
To enhance, by practice and reinforcement, the
skills of reading and following directions.
To enhance, by practice and reinforcement, the
skills of spacial perception.
To enhance, by practice and reinforcement,
manipulative skills.
Teacher's preparation:
Preparing to teach: Go to
the appropriate web site and download and print the pattern for the
model. For highest interest, I recommend starting with a
spacecraft currently in the news.
Put the model together
yourself. This will help to identify mistakes and confusions in
the instructions, and anticipate likely problems students may encounter.
Read up on the spacecraft, its
mission, data returned, so you will be able to answer student
questions, or at least direct them to an appropriate source.
Allow plenty of time, it almost
always takes longer than it seems like it should. Have work for
those who are faster, starting reports, helping the less
skilled, etc. Some may need time during lunch or after school to
complete their models.
A place to display finished
models also adds to student interest, and if public, is great PR for
the teacher.
Hanging the models with loops of
black thread allows me to display them in random positions, a subtle
reinforcement of the concept, "There is no up
or down in interplanetary
space." (The correct attitude of a spacecraft is determined by
its need to point its antenna at Earth, and its camera at its target.)
Materials needed:
A copy of the model for each
student
Glue, scissors, materials needed
may vary with different models
A place to store partially
completed models without crushing or losing loose pieces
If possible, posters showing the
spacecraft, from NASA or the manufacturer
Student Introduction:
(Not more than 3 minutes)
"The spacecraft ___________ has been in the news lately (pointing to
the poster). Who can tell us something about it?" Hopefully
some will volunteer useful information. If necessary, the teacher
supplies minimum explanation.
"Today we are going to build a model of the spacecraft ___________
(holding up the previously constructed model). Each of you will
get a copy of this pattern (holding one up to show). Be careful
to read all the instructions before you start. That way you will
know where you are going, and why sometimes things need to be done in
the right order. Also, you are less likely to throw away a tiny
piece which you will need. Now we will distribute the models and
materials." (Presumably you have developed an efficient system
for students to distribute materials with minimum time and disturbance.)
The teacher's function now is to patrol the room watching problems,
assisting or asking another student to assist those who need it,
commenting on neat work, and otherwise keeping the class on task.
