The SA1s have just passed.

There are exactly 126 days until the science PSLE paper.(from the date of this post)

As quoted by the wise, G.I. Joe ūüėÜ, “Knowing is half the battle”.

I have done an analysis of the 2018 PSLE Science paper and categorised the questions topically and thematically. Some things to take note of before looking at the details of the analysis:

  • ¬†Some topics are synergised as they are usually tested within the same question
  • An additional topic called “Experimental Techniques” is added
  • The analysis is not a predictor of the 2019 PSLE Science paper; however, it gives a rough trend of the question weightage set by SEAB
Below is the weightage based thematically:

The top 3 themes are:

  1. Interactions
  2. Systems
  3. Cycles
¬†It comes as no surprise because most of the upper block topics are found within these three themes. Notice that “Diversity” holds the least weightage because it consists of only the lower block topics like classification of living things and materials.¬†


Top 5 Topics

Here are the top 5 topics ranked in ascending order based on weightage:

This Upper block life science topic is quite challenging for a lot of students. The sub topics that are covered here are:

  • Composition of Air
  • Link with Photosynthesis
  • Link with Circulatory System
  • ¬†Human Respiratory System
  • Plant stomata
  • Fish gills
  • Link with Adaptations
This topic holds a weightage of 6%

We have a 3 way tie here. These 3 topics hold a 7% weightage each.

  • Adaptations
  • Heat and Temperature
  • Uses, Forms and Sources of Energy
 Adaptations is a VERY wide topic. The challenge for students is to have a good general knowledge and to know how to answer questions well contextually. 

Heat and Temperature is a rather complicated topic because the current syllabus does not require students to know about convection and radiation. However, a lot of questions tend to be directed towards to these other forms of heat transfer 

Forms, Uses and Sources of Energy is typically taught in Pri 5/6. Once again, this is a very wide topic as it can be linked to the topic of Environment as well. 

Number 3 on the list is Reproduction. This topic consists of Plant and Human Reproductive Systems; and Plant Seed Dispersal.

It is common for Plant Seed Dispersal topics to be linked with Adaptations. 

This topic has an 8% weightage. 

This topic holds a weightage of 9%.

Students will need a very good grasp on current affairs and be knowledgable regarding pollution, renewable sources of energy, biodegradability, global warming… It is a very wide topic.

And the topic with the highest weightage is Electricity! This topic holds a total weightage of 10%! That is enough to cause students to jump/drop an entire band!

This topic consists of a few of subtopics:

  • Electric Circuits
  • Electrical Conductors
  • Conserving electricity

Well, I hope this helps many parents and students to better prepare for the upcoming PSLE.
