# Surviving the PSLE (Part 2) – The Science Exam.

Science is a subject that many students find it challenging. Even though it is a very interesting subject the concepts taught can be quite hard to comprehend. The key points and way to describe the object/ activity has to be on point or else marks will be easily lost in a test/ exam. Sometimes a lot of description and explanation is needed for a 1 or 2 marks answer.

## How to best study Science then?

There are three main points that one needs to take note when one is doing a Science paper.

• What is considered sufficient details given to answer the question fully.
• Know which are the key words  that have to be mentioned in the answer that you give.
• Know how to classify, identify and describe an item or a process.

## Sample Question

a) Name the Process A (1 mark)

b) Explain how a physical factor in the environment has caused the difference in the decrease of mass of the dead leaves in the two places M and N. (2 marks)

c) Other then process A , evaporation could also cause the decrease in the mass of the dead leaves. Explain why ( 1 mark)

#### How would you answer the question?

a) Name the Process A (1 mark) – Decomposition

b) Explain how a physical factor in the environment has caused the difference in the decrease of mass of the dead leaves in the two places M and N. (2 marks)

Ans:- Place M may have contained more moisture than Place N causing the leaves to decompose faster , hence the difference of mass in both places.

Note for this answer you will need to Compare between both places.   It is not sufficient just to mention that Place M has moisture but Place N doesn’t have.

c) Other then process A , evaporation could also cause the decrease in the mass of the dead leaves. Explain why ( 1 mark )

Ans: The dead leaves contains water which contributes to the overall mass. The water in the leaves may have gained heat from the surroundings causing it to evaporate. With water evaporated there would be a decrease in the overall mass of the pile of dead leaves.

Note: Explain step by step in detail the how the process of evaporation affected the overall mass .

It is important to have a revision schedule drawn up to gauge if the child is able to cover all the topics tested from the Upper and Lower Block in Science. Here is a revision schedule that I came up for my students to ensure that are able to cover all topics before the Prelim in August

### What Revision Materials do you recommend?

I do use assessment books and past year papers with my students. I also recommend that they have at least one Science guide book as a reference guide. Here are some that I have used with my students.

How will you be preparing for the Science PSLE Exam?
