2015 PSLE Discussion and Strategies

[musiclover55]

For the fertiliser question, I put 4. For the bumper car property, I put strong. For the curved metal question, I put 1.

[quote=\"manifits\"]i wrote strong

That's what I wrote too!

tell me reason leh.

They asked property to play the bumping car...[/quote]I'm pretty sure there's more than one property suitable for the bumping car. For my reason: It must be strong so that part W will be able to withstand the force and not break when bumping.

whats 1?

Those are what I put too! :please:

whats 1?

To allow the metal pipe to expand

[musiclover55]

To provide space for the metal pipe to expand i think.

Paper 2, 2 questions that ask for 2 reasons why same variable was used.


I can remember 1 of them is...

The http://i.ytimg.com/vi/EBc9eRVJP0M/maxresdefault.jpg. (they didn't say the name, but I look I know)

They threw them and recorded height started throwing and distance travel.

So they ask for 2 reasons why use the same seed in the experiment.

What's the answer? Me wrote (roughly):[list=1]

What's the answer? Me wrote (roughly):[list=]

[*]Not all seeds are wing-like structure, wing-like structure seeds have greater exposed surface area so it have more air friction so it takes longer time to land on the ground

[*]Seeds with smaller mass will travel for a longer distance because it'll be blew easier by the wind

[/list]Another question and they ask for 2 reasons too, but I forgot. Anyone remember please share.

My answer:
1. So that we know the results of the experiment if affected by the height it was dropped and not the type of seed
2. So that we know the results of the experiment if affected by the height it was dropped and not the mass of seed

I wrote that the length of the wing like structure will be the same and the mass will also be kept the s@me. :frustrated:

I don't dare to write this because I had been writing like that and the teacher wrote \"So?\"

That's why I'm determined to throw the whole chunk in, not giving the teacher any chance to ever write that on my paper.
