Class notes & Key learnings
STEM learning in-class presentation
Technology - NFC
<aside>
💡 Interesting takeaways
- NFC can store a large amount of data
- Apple shortcut customisation using NFC
</aside>
Engineering - Gear
<aside>
💡 Interesting takeaways
- Torque = force needed to cause an object to rotate around an axis
- Gear ratio = teeth driven / teeth driver
- Gear output speed (RPM) = input speed / Gear ratio
- Gear output torque = Input torque × Gear ratio
- Gear direction = if the driving gear rotates clockwise, then meshed driven gear will rotate counterclockwise.
</aside>
Mathematics - Probability
<aside>
💡 Interesting takeaways
- Monty Hall problem
Switching gives you a better chance (2/3) of winning the car, whereas sticking with your original choice leaves you with only a 1/3 chance.
</aside>
Hilbert's paradox of the Grand Hotel
<aside>
💡 Interesting takeaways
- Infinite sets can have the same size, even when "expanded”
- Subsets of infinite sets are also infinite

In-class reflection
What worked well? What was effective?
- Experiments were good, physical representations, engaging presentation, interactions within the group will help, idea of facilitation instead of teaching, show the not-commonly-known facts through physical representations
- There were many fun examples and good slides
- Math calculations were difficult for gears, writing down the formulas helped a lot
- Monty hall example was difficult to understand, using physical examples to prove and convince the audience
What could be improved? What was not effective?
- Explanation of the examples can be more detailed, the building up of concepts can be better.
- Gears group can possibly use more physical examples to help with visualisation
- Math group can rehearse more to make things less confusing, facilitating is important but delivery is key
