Extracted this question from CHIJ CA1 question 18. There is a picture of a plant that requires students to identify the parts.


The answer state singular term like flower, root, leaf and stem. Would it still be acceptable to name the parts in plural term as flowers, roots and leaves?
Thanks.

Answer: Yes.

Thank you.

Hi


Can someone pls help me with this que?

2 earthworms are placed in a dish. Half of the dish is covered by a piece of cardboard and the other half is covered by a glass sheet. The dish is then placed under a light source. After 20 minutes later, the earthworms can be seen under the cardboard. What conclusion can you draw about the behaviour of earthworms in this experiment?

Thanks in advance.

Earthworms, like all living things, respond to their surroundings. They like dark places. So it respond to the light source above the dish by moving away from the light towards the darker side of the dish where the light is blocked by the cardboard instead of under the glass sheet which is transparent and allow light to pass through.


How many marks is your question? If one mark, probably my first sentence suffice.

Hi jedamum

Only 1 mark is allocated for this question. From yr answer, the Behaviour of the earthworms is actually asking for the Characteristic of living things? This is the part which confused me. My ds said answer is earthworms like dark places will do since the question is not asking for what characteristic of life will the earthworms show in the experiment?

[jedamum]

Maybe get your kid to double check with his work book or teacher?

My understanding is, behaviour means the reaction. Conclusion of behavior, meaning conclusion of their reaction, will be the earthworm like dark places. Your kid is correct!
Maybe it is just me, I tend to get my boy to nswer at least two points for one mark question. So I would include the respond to surroundings.

You may be surprised sometimes your kid may be right!

Hi jedamum


Yes, sometimes it is best to put in both answers just to be kiasu. I just do not understand why the teacher used the word behaviour. It would be much easier if they just ask you to predict what happened 20 min later and which characteristic of living things does this experiment show? Anyway thanks for yr reply. Still a lot for me to learn as science was my worst subject.

[jedamum]

No problem.


My boy did his lower block revision recently and this is one of the question. The two questions relating to the earthworm were,

1. Predict the observation he would make
2. Explain your prediction
I usually spend quite some time discussing with my boy as at times school really do tell them the requirement on answering.

I am still learning too.

In lower primary,answer should be short(means precise explanation needed),don't write whatever you know.Teachers encouraged the kids like that.cos they wanted to inculcate the habbit.cannot be write \"it\".You have to say specifically.Need to write full sentence,sometimes the sentence technically correct but for sci, wrong.

The earthworms respond to changes in their surroundings.
Or
The earthworms respond to environmental stimulus.
