Learner
Prior knowledge of welding and cutting techniques and procedures.
Prior to the lesson, have the students bring empty (clean) vegetable cans from home.
You could also ask the cafeteria to save their cans.
Introduction
Introduction (LSI Quadrant I):
This is a great holiday gift project (Christmas, Mother’s Day, etc…) for the kids to do.
Some students may like this project better than others. It creates a fun environment
when using the cutting torch and shop materials. This project is also a good way to
teach the kids how to cut a straight line.

A suggested way to start is by talking about arts and crafts. Right now there is a huge
demand for anything rustic. This project falls under the rustic category. Inform the
learners that there is more to welding and cutting than just “welding and cutting”. Money
can be made by doing metal arts and crafts.
Outline
Outline (LSI Quadrant II):
Introduction.
Review all the safety procedures and equipment
usage procedures.
Show PowerPoint.
Demonstration:
1. Place a can on the cutting or welding table.
2. Find a starting point in the middle of the can.
3. Lower the welding tip down towards the can.
4. The neutral blue flame should slight
penetrate through the can
5. Cut a straight line through the ribs of the can
stopping where the ribs stop.
6. Pick the tip up.
7. Move about a 1/8 inch over and cut another
line.
8. Repeat this process until the can has been
completely cut through all the way around.
9. After the can has cooled, place one hand on
the inside of the can and begin bending and
prior outward so that a slight bulge begins to
form in the middle of the can.
10. When you can no longer use your hands,
apply slight pressure to both ends of the can
until the desired bulge has been achieved.
Instructor Notes:
This lesson will help the
student learning welding to
increase their speed and
proficiency.
1. Make sure all paper
and glue has been
removed from the
outside of the can
2. I have found it easier
to start in the middle
of the can rather than
on the ends
3. Be ready to cut once
the tip has penetrated
the can, otherwise the
metal will melt too fast
4. Most vegetable cans
are ribbed. The ribs
make it easier for the
kids to see the
stopping point
5. Make sure that the tip
is picked straight up
at each end so that
the can will not
continue to melt in
undesired areas.
6. Roll the can over and
continue process
7. Make sure the kids
use gloves when
handling and bending
the bulges because
the can will be sharp
8. Bending from the
inside is sufficient
when utilizing smaller
cans, but the bigger

11. If the bulge seems “lopsided” use your
hands once
12. Finally apply paint using the spray paint if
deemed necessary.
Ask if there are any questions.
(gallon size cans will
require pressure at
both ends.
9. It may take several
attempts to perfect
this project.
10.Other designs can
be used rather
straight lines. (exp.
Hearts, stars or other
shapes
11. Refer to power point
pics if more detailed
information is
required

the follow up lesson

Lights Lesson Plan.
Application
Guided Practice (LSI Quadrant III):
Teacher works through problems/activity as students observe/follow along and record
process/solution and/or take notes.
Independent Practice (LSI Quadrant III):
Students work independently or collaboratively (pairs, small groups, large groups,
teams, etc.) to complete a new assignment similar to the guided practice assignment
and related to the lesson objective.
The major difference between the two application components is that independent
practice is usually graded and recorded, though typically carries a less significant weight
than a final, formal evaluation activity. Be sure to include all handouts, printed
directions, and criteria on which practice assignment will be evaluated.
Summary
Review (LSI Quadrants I and IV):

Ask learners if they have any questions
Have each student state one fact that he/she learned during the lesson
Restate lesson objectives or have students recall lesson objectives.
Evaluation
Informal Assessment (LSI Quadrant III):
Select one of the following methods (or a similar method) for conducting informal
evaluation of student understanding and/or learning prior to formal evaluation for
grading purposes:
•
Teacher will monitor student progress during independent practice/application
and provide independent re-teach/redirection as needed.
•
Students will complete “XYZ assignment” as a class work grade.
•
Teacher will conduct periodic progress checks and provide students with
feedback in the form of an objective and/or subjective checklist based on
project/assignment criteria (be sure to include a copy of the suggested
instrument to be used and align criteria with formal assessment).
Formal Assessment (LSI Quadrant III, IV):
Demonstration of process or experiment – be sure to include printed directions for
students as well as an evaluation checklist to be used to evaluate the demonstration.
Extension/Enrichment (LSI Quadrant IV):
•
Peer teaching, tutoring, mentoring in welding.
•
Creating a new product and/or performing a curriculum-related service for a
paying customer.
•
Applying learning/content to personal life (work or home) or other projects that
the student wished to develop.
