Science reasoning where the target school requires it
Use scientific evidence when the chosen school includes science.
Original Model Test for Exam unit. These questions and suggested practice times are independent Kidemy material, not an official or past paper. Choose modules for the target programme; all listed subjects are not required for every applicant.
Learn the idea
A fair test changes a relevant factor while making comparison conditions similar. Repeats assess consistency; they do not automatically remove a biased method. Describe a mechanism rather than merely naming a process. This optional unit does not assert that every school tests science.
Worked example
Two identical plants receive different light levels while water and soil are kept similar. Growth is measured over the same period. Several plants per condition would provide a more useful comparison than one in each.
- State the question and variables.
- Control relevant conditions.
- Report the observation and a cautious conclusion.

photosynthesis
Photosynthesis transfers light energy into chemical stores.
Write in your own words. A guardian or teacher should review this response.
Show model answer and explanation
No. It requires comparable conditions, not identical biological responses.
Review both the conclusion and its reason. It requires comparable conditions, not identical biological responses.

Show model answer and explanation
Individual plants vary, so repeats help show whether the pattern is consistent.
Explain variation.

Show model answer and explanation
An observed difference might reflect the individual plants rather than the light treatment.
Connect the limit to the design.
Optional science model test
Write a safe investigation plan on paper only.
Review with a guardian or teacher
- Name variables.
- State a measurement rule.
- Check the target school’s subjects before including this unit.
