Summary of the videos content:
> all matters are made up of tiny particles (molecules)
> solid: particles are closely packed, cannot move across each other, vibrate in position
> liquid: particles loosely packed, can move across each other (flow)
> gas: particles are far apart, not touching each other
I hope by using particles to explain mass, you have a clearer understanding of what causes the 3 states of matter - solid, liquid and gas, to have its unique 3 properties (shape/volume/compressed) as seen below:
Properties of the 3 states > solid has: definite shape definite volume cannot be compressed
> liquid has: no definite shape definite volume cannot be compressed
> gas has: no definite shape
no definite volume
can be compressed
Start your revision early and when in doubt, always ask!
Do you know that whenever I watch this video, it really brings a smile to my face?
To all those pupils who tried their best and also had fun at the same time, I hope this would be one of your most memorable experiences in EDP.
Love,
Ms Yeo
p.s: Quality is rather poor as it's shot with a handphone. The school will be uploading all the performances from that day too, hopefully it'd be better! (:
