How To Soar in PSLE - BTPS Way!!

Interact with complex questions / graphs / pictures to pick up valuable clues (don't highlight - just use your pen to underline words or scribble notes)

Start with Booklet A and do it meticulously with full focus - explore all 4 distractors before making final choice.

MANAGE your TIME - to score well, you need to try to finish ALL questions.

Specific answers = answers that are relevant to question.

When confused, choose any of the following strategies:

1. Ask, "What Science idea is being used in question?"
2. Pose other questions to clarify your thoughts
3. COMPARE to another set-up
4. COMPARE to a reverse situation
5. Connect to your knowledge in life (yes, you do have lots of prior / other knowledge)
6. Break down your answer in steps before crafting final answer.


Common problems with wrong answers:
*Answers are generic/vague and do not connect to that specific question
*Answers are not scientific and do not explain using Science ideas
*Answers do not make use of data provided when asked
*Answers did not make comparisons - use words like more/most etc..when asked

Creepy Creepers

What are the similarities and differences in the two plants below.
How do they overcome the problem of their weak stems?

they overcome it by the help of objects that they can hold onto and grow on.the stems will curl and grow around an object for example railings so that they are able to get sunlight.

Some plants could not be able to grow tall enough to compete with other for sunlight due to their weak stem.Their stem is not strong enough to support the plant unlike others.How do they get sunlight or more then?These plants need the help of other plants or trees to get more sunlight.Some of these plant help parts which will help them to "hang" on the trees,plants or an object.An example of a part that some plant with weak stem have is tendrils.Tendrils helps the plant to "hang" on the object which will then help the plant to grow taller for more light.Are there any other parts that plant with weak stem have which will help them reach up to a greater height for more sunlight?Another part that these plant process is clasping roots.Such roots help the plant to cling on the objects and thei weak stem will then grow round the object to a taller place where they can get more sunlight.

Their similarities are that they both have weak stems.

Their differences are that in the first picture, the plant's leaves are jagged-edged while the other plan'ts leaves are entire edged. Also, in the second picture, the plant's leaves have holes in them while the picture of the first plant does not have holes in its leaves.

As they have weak stems, they will have something that helps them to get sunlight! It is not their tendrils though. Tendrils also play a part, however, for a plant with a weak stem, it not only must have something like tendrils to cling onto SOMETHING. The SOMETHING here is the support! Tendrils and the support are like the skeletal system and the muscular system in our body that works together to support our body right? So in the end, if the plant has tendrils, without a support, it is useless because it cannot get enough sunlight. With a support, if the plant does not have tendrils or something to cling onto the support, the support is also useless. But if both is present, then, the tendrils or some other structural adaption would 'climb' up the support and receive more sunlight than when it does not 'climb'.

The plant is just like a human's body I guess... They are like babies I guess. We must respect the plant too!

Some plants have tendrils to help them to crawl and grab hold of things. Others have weak stems but in order to make up for that loss, they can climb onto other high things like trees, to get more sunlight and water, while their roots are still attached underground so nutrients can be absorbed.

crawlers can cling onto long and thin items and these tendrils helps the plant as if it was a root but only can hold on to something

As all of you have said,they cling on to objects with their tendrils and so on and so forth...I would like to address another point this question might be looking for...How do they get necessary things to survive such as sunlight,water,nutrients and so on?
For water and nutrients,compare the weak stems to big and strong stems(an example;a tree trunk),plants with big and strong stems need lots of water and nutrients to keep their stems hard and firm while those with weak stems needs not much water as they will not be as strong as trees.To make it easier for those who does not understand what I'm saying,like what Yilin said,plants are like humans.Do you notice some people which are strong,bulky and they eat lots of fruits while a skinnier person eats only instant noodles for every meal but is as fit as the bulky guy.The skinnier one does not need much food for him to be fit like the weak stem.
As for the Sunlight,I observed that there was holes on the second plant...Why?Well,I came up with a simple answer,as sunlight reaches the plant,not a lot is taken by the 'tallest' leaves as the light passes through the holes and gives the leaves below an almost equal amount of Sunlight.(The first plant creeps so it gets sunlight but they do not need much food so they need not much sunlight too to photosynthesise.)

Science Around Me (SAM)

SAM is a Science journal that allows pupils to express themselves in their favourite ways about Science.

SAM is another great opportunity for pupils to THINK and TALK Science in a medium that is customised to their learning styles.

SAM allows teachers to informally assess understanding of the child and clarify misconceptions in their learning.

When Ice Changes into Water by Goh Chee Yan - 5G

Do you wonder whether the mass of ice changes when it melts into water. Try this out:

1. Put a few ice cubes into a plastic bag
2. Tie the mouth of the bag tightly
3. Weigh the bag of ice cubes (if there is condensation outside the bag, wipe it dry before weighing)
4. Place the bag in the sun
5. When ice has melted, wipe the outside of the bag dry (refer to step 3)
6. Weigh the bag

You will discover that the mass of the bag remains the same!
There is no change in mass when ice melts!!
