The medieval Times


A walk-through the medieval times, learning of the catapult and it’s invention.


It is really fun building the catapult and learning about the medieval times.


This is the Catapult I have built. Today we learnt a few principles on energy. This with the elastic band pulled backwards is known as potential elastic energy.



I had so much fun in lego class. Besides building different models; what I’ve learnt in school is also enhanced. Kinetic energy, Potential energy and elastic energy. The castles in medieval times are really beautiful.


This is the catapult I have built. I’ve learnt about kinetic energy as a movement energy.


I had fun playing with the catapult  that I’ve built. I’ve also learnt that rubber bands has elastic energy.

Aim, lock, FIRE!

Here we are trying to get our candies into the target! 😀
