What about the seeds in the apple. Are they living things?

Hi atutor2001

Some interesting articles on seeds.

Extracts from the article:
Is a seed a living thing?
A seed is not exactly a living thing, though it maintains the potential to become alive

Wah piang, so is a seed living or non-living thing? :stupid:

I have not been following this thread closely.


A fruit should be considered a living thing because under certain conditions, it grows, reproduces and dies.

I think our nail is not really a living thing. It is made up of dead cells. Änother example will be our hair.

Can any Science teacher confirm?

A thing is classified as a living thing if it meets the following conditions:
1. It can move by itself.
2. It can grow, reproduce and die.
3. It respond to changes or stimuli.
4. It needs air, food and water to survive.

An apple is no longer considered a living thing once it is pluck from the tree as it will not be capable to meet the above criteria. Nails and hair will be classified under non-living things that are once alive as they are made up of dead cells.

The school requires us to buy P3/P4 cycle & energy science textbook for next year. Can anyone advises me if the school will continue to touch on diversity, system and interaction?


If I want to teach my son in advance, which topic should I start first?
:roll:
Any mummy or daddy can advise me?

Thank you very much.

Hi she0407


My ds school taught cycle first and then followed by energy. P3 syllabus for Science will still be tested in P4.

Regards

[she0407]

ok, I will start teaching cycle first.


Thank you very much!

A seed is a living thing because it can grow, it responds to stimuli- it grows then it is given Water, Oxygen and Warmth (easy way to help your child remember is WOW-Water, Oxygen and Warmth.

Hi,


I was looking at my P3’s science book on diversity (plant). It seems to me that the P3 has to "memorise" the plants in order to categorise a particular plant into flowering or non-flowering, floating or half submerged or completely submerged. Any parents can advise how you teach your child, esp when they have not come across plants like cabomba, hydrilla, etc?? Btw, are these part of PSLE syllabus? Thanks.

I tried to do the P3 Science exams from the top schools and... there's no way I can score 100 for it myself! It's REALLY tough considering that the kids just started science this year. Aside from learning names and stuff (thorax, abdomen, etc), the questions were focused more on application of what they learn... so it was really like conducting investigative work. A lot of the questions were really subjective.


Some examples:
1. What are the purpose of feathers on peacocks
(A) They help the peacock fly
(B) They protect the peacock's skin
(C) They are used to attract mates
(D) They keep the peacock warm

Answer:
(1) B, C, D
(2) B, D
(3) A, B, C, D
(4) C

2. A Molly:
(A) Gives birth to its young
(B) Lays eggs
(C) Is a plant
(D) Is an insect

Anyone dare attempt these questions? Play fair - no googling until you actually tried to answer.

Question 1)1
Question 2)B

Mollies are live-bearers, as are guppies and swordtails.
