Heavy but easier!

a)      Car tyres comparison.

l       Teacher Pik Xia was kind enough to lend us her Proton Wira car tyre. I took my spare tyre. At first kids compared. My tyre belongs to Perodua MyVi. Of course, MyVi tyre is smaller than a Wira as my car body is smaller and lighter. Proton Wira is about 14 inches while MyVi 13 inches. My car would be unsuitable to take in 14 inch as the wheel gap for MyVi is too small!

l       Kids compared the tyre tread and the broadness of the tyre. They tried lifting the tyres. Obvioulsy MyVi tyre is lighter. Some kids could actually lift up the Proton Wira tyre by themselves…..woh!

b)      Moving the tyres.

l       Kids queued to think of a way to move the tyres from front to back. Immediately they asked me if they could roll….haaaa! That’ll be the easiest way. Surprisingly, kids could roll the bigger tyre easily compared to the smaller one.

l       Conclusion: We discussed the process. The big tyre is heavy but easier to roll. That shows stability as the tyre surface is braoder.

c)       Racing Car.

T: Do you think a racing car has small or big wheels.

l       Kids said “big”. In fact, bigger and broader than Proton Wira.

Jia Xun: Bigger tyres allow them to drive very fast.

l       Alex Yoong is our famous Malaysian F1 driver while Michael Schumacher is the famous world F1 driver from Germany.  I’ll talk about Alex tomorrow due to time constraint.

l       Racing cars have to be driven on racing circuits. Because they speed so fast, it’s very crucial top change their tyres as they wear off very quickly! The racer would stop for a while and the his mechanic team takes about 6 seconds to change all the 4 wheels…….woh! That’s awesomely quick!

l       It’s a thrilling but dangerous sport! You have to be very skilful and brave to a be an F1 racer!
