Use Data in PSLE Science Conclusions
Part 1 of 3 of the PSLE Science OEQ Guide: writing the answer is its own skill, and it is rarely taught. Here are the seven ways marks go missing in Booklet B.
The question says, "Support your answer with data from the table." You work out the right conclusion, but write it on its own. The evidence the question asked for is missing.
Read the instruction first. "State a conclusion" or "describe the relationship" may need only a clear statement of what the results show. "Support your answer with data" also needs the relevant readings. A table on the page does not mean every answer must contain numbers.
When the question asks for evidence
Suppose you are asked which plant grew more and to support your answer with data.
Name the plant, then compare its increase in height with the other plant's. Keep the units. Choose the values that support your comparison; you do not need to copy the whole table.
Here is an example where the instruction explicitly asks for evidence.
| Plant | Height at start | Height after two weeks |
|---|---|---|
| A | 4 cm | 6 cm |
| B | 4 cm | 15 cm |
When there are no clean numbers
Not every question gives you a number you can quote. Sometimes it's a line that rises, falls or flattens with no readable values. Sometimes it's a table where the pattern across the rows matters more than any single one.
Then quote the pattern instead.
"As the temperature increased, the number of bubbles increased."
"The mass fell quickly, then levelled off."
A stated trend can support an answer too. If the question only asks for the trend, that statement may be enough. If it asks you to explain the trend, you also need the relevant science.
Some questions ask for that trend sentence and nothing else. Writing one is Episode 5.
