my boy written answer (2) and the correct answer is (4).

Since it is testing if it absorbs water, water must be the only variable factor… The rest must remain the same in the control setup.


For option 2, the layer of oil is gone and hence not a ‘fair’ test.
For option 3, there is only 200ml of blue water.
With option 4, everything remains the same, except that now water is ‘absent’.

My P4 girl did not do well for SA1 Science OE…Any kind advice on which assessment books are better for OE, with clear explanation on keywords and answering s.

Teacher commented that her answering technique is not there. but when we let her do school test papers she seemed ok, and last year P3 Science result also ok…

Panic mode now!!! thanks a lot…

Hi mwchua
I am using Janet Sim's Challenging Science (EPH) lower block - I find the explanation pretty clear whereas my friend thinks \"Everything you needs to know abt Science (EPH)\" is good. You can also check out Teachers@work series.
