set up z. because water cannot be compressed, so the amount of distance pressed down at Part P will be the same amount of distance raised at the other end at Tray T.

All the other 3 set ups have air in it, and as air can be compressed, the equal distance pressed down at Part P will result in a slightly lesser amount of distances raised at their respective Tray T as compared to Set up z.

something like that ba...

other parents, appreciate verification. TQ.

Set up Z, because WATER CANNOT BE COMPRESSED. As seen in all three other set ups, W, X and Y, air is present in the container. So when you push it, the distance moved is not as much(because air can be compressed) as set up Z.



My 2 cents.

My dd scored 28.5 out of 50 for CA1. I’d like to help her score at least 10 points more for SA1.


If your dd/ds is doing well in p4 science, can you share how he/she is doing so?

Is it because dw/dh is good in science and thus able to help your kids by explaining the concepts?

Does your dd/ds have tuition? Can you share which tuition centre it is or is it one-to-one home tuition?

What books do you use to supplement the school text/work books?
