What is STEM?
a) Science, Technology, Engineering, and Mathematics.
b) Where the grant money comes from these days.
c) Not the humanities.
d) What they now call the Science Fair.
e) The latest fad.
f) All or most of the above.
What is Science?
• A process for studying the universe.
• Thought to be based on the
Scientific Method

4.
Ask a Question
Do Background Research
Construct a Hypothesis
Test Your Hypothesis by Doing an
Experiment
5. Analyze Your Data and Draw a
Conclusion
6. Communicate Your Results

What is Technology?
• Things and systems useful to people.
• Can be simple or complex

What is Engineering?
• Using specific math and science to
create, improve, or operate technology.
• Uses the Engineering Design Process

What is Mathematics?
• Who knows?
• A numbers tool used to quantify, display, and analyze data.
• Wiktionary (who knew) says: An abstract representational system
used in the study of numbers, shapes, structure, change and the
relationships between these concepts.
• And that, before the beginning of the 20th century, it was proper to
say "My mathematics are not very good".
• Most of what I thought of as math was taught in the Engineering
Department at the college.
• What Kids in STEM most need to know is Algebra (perhaps systems of
equations).
Aren’t I already doing
STEM in my classroom?
•Of course you are, but nobody knows it.
•Why? Because you fail to state the obvious!
• In lesson plans
• In project handout/instructions
• In talking to parents?
• And in…
The Power Boat Challenge
• Boat to race in a rain gutter.
• Design related activities in Technology,
Science, and Math classes.
• Construction and hull testing in
Technology Class
• Weights and displacement in Science
class.
• Propelled test in Tech ed.
• Analyze results in Science and Math
classes.
