Sample Year 7 Science questions
These sample questions are visible on the page before login. They show Year 7 classification, ecosystems, mixtures, Earth-Sun-Moon systems, forces, and inquiry graphs before opening the demo.
Year 7ScienceClassificationhardclassification key
1. A dichotomous key first separates animals with feathers from animals without feathers, then separates animals with fur from animals without fur. Which observation would place an animal in the bird group?
Choices
It has feathers and no fur.
It has fur and gives birth to live young.
It has no feathers and no fur.
It has six legs and antennae.
Explanation:
The first branch uses feathers. An animal with feathers follows the bird branch, while fur is used on a different branch for mammals.
Year 7ScienceEcosystemshardfood web
2. The food web shows grasshoppers eaten by frogs, and frogs eaten by snakes. If the grasshopper population falls sharply, what is the most likely direct effect on frogs?
Choices
Frogs would likely decrease because they have less food.
Frogs would increase because snakes eat them.
Grass would disappear first.
Snakes would become producers.
Explanation:
Arrows show grasshoppers provide food for frogs. If grasshoppers decrease, frogs have less available food, so the frog population is likely to decrease.
Year 7ScienceParticle model and mixtureshardseparation diagram
3. A mixture contains sand and salt water. Which first step best separates the insoluble sand from the salt solution?
Choices
Filter the mixture.
Use a magnet on the salt.
Freeze the mixture and keep the ice only.
Shake the mixture harder.
Explanation:
Sand is insoluble, so filtration traps the sand while the salt solution passes through. Evaporation could later separate the dissolved salt from water.
Year 7ScienceEarth, Sun and Moon systemshardEarth-Sun-Moon diagram
4. The diagram shows the Moon between Earth and the Sun. Which phase is observed from Earth when the lit side mostly faces away from us?
Choices
New Moon
Full Moon
First quarter
Lunar eclipse every night
Explanation:
When the Moon is between Earth and the Sun, the sunlit half mostly faces away from Earth, so the phase seen from Earth is New Moon.
Year 7ScienceForces and motionhardforce diagram
5. A box has an 8 N push to the right and an 8 N push to the left. What is the net force on the box?
Choices
0 N because the forces are balanced.
16 N to the right
8 N to the left
64 N because the forces multiply
Explanation:
Equal forces in opposite directions cancel. The net force is 0 N, so the forces are balanced.
Year 7ScienceScience inquiryhardinquiry graph
6. Students measured plant height after growing seedlings with 2, 4, 6 and 8 hours of light each day. Which light time produced the tallest plants in the graph?
Choices
6 hours
2 hours
4 hours
8 hours
Explanation:
The tallest bar is at 6 hours. The 8-hour bar is lower, so this dataset does not support the idea that more light always gave taller plants.
For parents comparing Year 7 Science support
Year 7 science practice should help students connect new secondary science ideas to visible evidence: classification keys, food webs, particle models, Moon phases, force arrows, and simple inquiry graphs. These examples preview that visual reasoning before the no-login Year 7 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 7 Science practice questions?
Yes. This public demo includes reviewed Year 7 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.
