Math and Engineering Teaching Club
signal / inquiryask -> teach -> make
Bring questions into classLet curiosity get its hands dirty
A student-created, student-centered math and engineering teaching club — we turn abstract ideas into things students can touch, discuss, and question again
01 — Explore METC
We do not finish the answer — we hand over the question
METC was started by high-school student educators. We believe learning happens not by watching a perfect demonstration, but by moving through guesses, making, failure, and explanation.
Teaching Mission
Help more students see that their ideas carry weight in mathematics and engineering.
Educational Philosophy
Students design classes for students: real questions connect knowledge, and what we make becomes evidence of learning.
Curiosity becomes a question. A question becomes something we can build.- 01
Curiosity
Begin with a phenomenon worth asking about
- 02
Discovery
Make room for guesses, failure, and another look
- 03
Teaching
Turn understanding into something shareable
- 04
Connection
Bring peers, disciplines, and the real world together
02 — Teaching Design
A class is first designed with care on paper
From syllabus to slides to the materials in each student's hands, every page is shaped around one question: where will a real discovery happen?
UNIT 08 / GAS PRESSURE
How can baking soda and vinegar launch a bottle rocket?
Learning objective
Use a safe bottle rocket to observe how carbon-dioxide pressure and Newton's third law work together.
Materials
- 500 ml pressure-safe plastic bottle
- white vinegar · 50–100 ml
- baking soda · up to 2 scoops
- paper towel or filter paper
- rubber stopper and string
- goggles and gloves
- 101
Pour vinegar into the bottle
- 202
Hang the baking-soda packet at the mouth
- 303
Seal, invert, and secure the bottle
- 404
Shake, stand 3 m back, observe launch
Margin note: keep the soda dry until the bottle is sealed. Goggles on; observe from the safety line.
03 — Classroom Activities
Knowledge is not displayed — it happens on the table
Teachers and students gather around the same table. Every conversation, tilted model, and round of retesting is part of the real class.
01 / 0504 — Student Voices
After one class, what stays with them?
I used to think engineering meant making the correct answer. Then I learned that when the model falls, that is when we really start thinking.
