Hi anyone knows the answer for MCQ question with one of the plant's leaves tied inside a small plastic bag?

What is the level of oxygen inside the bag after 2 hours? (Answers in graph format)

a) increasing /
b) decreasing \\
c) increasing then decreasing /\\
d) stays constant (straight horizontal line on graph) ----

Increasing then decreasing. The carbon dioxide in the bag will be used for photosynthesis until no carbon dioxide left then oxygen produced during photosynthesis will be used for respiration until more carbon dioxide is available for photosynthesis, repeating the cycle over and over again

Science paper this year was apparently very easy, the booklet b especially

CL/ML/TL Compo picture


Pict 1- Students + teachers in class getting ready for a trip to the zoo

Pict 2- Student B touching student A’s bag while boarding the bus

Pict 3- Student B fighting with student C over a bag of potato chips

Pict 4- Student B swinging a bag around a monkey in the zoo

Pict 5- Student A, B and C trying to get the bag which the monkey stole and hanged on a tree

Pretty hard to link the pictures together

so far, based on above discussion, only 1 question is deemed difficult, out of the entire two Maths papers (1 and 2), because don't see students bring out other challenging Maths questions.

If is only just 1 difficult question, then cannot conclude that Maths is tough, because in order to segregate out the (AL 1 vs. AL 2) students, definitely they have to set some tough questions. Otherwise, everyone will score AL 1, for today Maths

There is definitely more than 1 question that is difficult. In fact, there are numerous. It just isn't brought out yet as the students forgot how the question was.

If students in Singapore came out of the exam crying, it can't be over just one question.

[quote=happydaddy post_id=2040144 time=1633084396 user_id=5470]Well, you are using algebra leh. No mark given leh.

Algebra is allowed, it's in the syllabus

It is strictly not allow in problem solving. you will get only answer mark but not working mark.

I believe the all the P6 teacher has highlight this issue to the students many times. Strictly NO algebra allow, else no mark will be given for the working.[/quote]My son and I clarified with my teachers as he uses algebra very frequently. It is allowed and can be used.

Helen and Ivan had the same number of coins. Helen had a number of 50-cent coins and 64 20-cent coins. These coins had a mass of 1.134 kg. Ivan had a number of 50-cent coins and 104 20-cent coins .

(a) Who has more money in coins and by how much?(2)

(b) given that each 50-cent coin is 2.7g more heavier than a 20-cent coin, what is the mass of Ivan’s coins in kilograms? (2)

My son says that this was the hardest question in the paper, most could not solve. He got part A but he forgot what he got for part B, he said he most likely got it wrong, like many of his classmates.

The answer for A is Helen and by $20
