Sample Year 9 Science questions
These sample questions are visible on the page before login. They show Year 9 feedback systems, chemical reactions, carbon cycling, waves, energy efficiency, and inquiry graphs before opening the demo.
Year 9ScienceBody response and feedbackhardfeedback model
1. The feedback model shows body temperature rising above normal. Which response helps return body temperature toward normal?
Choices
Sweating increases heat loss.
Shivering increases heat production.
The body stops detecting temperature.
Blood carries no heat.
Explanation:
When body temperature rises, sweating helps transfer heat away from the body. This is a negative feedback response because it works against the change.
Year 9ScienceChemical reactionshardparticle model
2. The particle model represents hydrogen reacting with oxygen to form water. Which statement is consistent with conservation of atoms?
Choices
Hydrogen and oxygen atoms are rearranged, not destroyed.
Hydrogen atoms become oxygen atoms.
The products have no atoms.
All oxygen disappears during the reaction.
Explanation:
The reaction changes how atoms are grouped. Conservation of atoms means the hydrogen and oxygen atoms are still present in the products.
Year 9ScienceCarbon cycle systemshardcarbon-cycle diagram
3. The carbon-cycle diagram shows carbon moving from the atmosphere into plants, then into animals. Which process moves carbon from air into plant biomass?
Choices
Photosynthesis
Combustion
Predation
Sedimentation only
Explanation:
Plants take in carbon dioxide from the atmosphere during photosynthesis and use it to build biomass.
Year 9ScienceWaves and energy transferhardwave diagram
4. The wave diagram shows one full wavelength between two crests. If the crests are closer together, which property has decreased?
Choices
Wavelength
Amplitude
Volume
Mass
Explanation:
Wavelength is the distance between matching points on consecutive waves, such as crest to crest. Closer crests mean a shorter wavelength.
Year 9ScienceEnergy efficiencyhardenergy-flow diagram
5. The energy-flow diagram shows 100 J of input energy, 65 J useful output and 35 J wasted energy. What is the efficiency?
Choices
65%
35%
100%
165%
Explanation:
Efficiency is useful output divided by input, then multiplied by 100%. That is 65 J / 100 J x 100% = 65%.
Year 9ScienceScience inquiryhardinquiry graph
6. Students measured reaction time at 15 C, 25 C, 35 C and 45 C. Which temperature had the shortest reaction time in the graph?
Choices
35 C
15 C
25 C
45 C
Explanation:
The shortest bar is at 35 C, so that temperature produced the fastest reaction in this dataset.
For parents comparing Year 9 Science support
Year 9 science practice should prepare students for Year 10 by connecting body feedback, reactions, carbon-cycle systems, wave models, energy efficiency, and investigation data to clear evidence. These examples preview that visual reasoning before the no-login Year 9 Science demo.

A strong way to preview the full Skill Align practice flow
Want more than this sample set?
This public preview is intentionally small. Full access adds more practice sessions, broader topic coverage,
saved student history, and structured learning by year and subject.
Does this page include Year 9 Science practice questions?
Yes. This public demo includes reviewed Year 9 Science sample questions so families can preview the Skill Align practice style before regular use.
Can students try the demo without signing up?
Yes. The public demo can be opened without signing up, and the attempt stays in the page instead of being saved to a student record.
How does this demo relate to curriculum coverage?
This demo is linked with the Year 7-9 Science curriculum coverage page, where parents can compare the broader topic and pathway structure used for Skill Align practice.
