What is a practice skill?
A practice skill is a focused topic or question type designed to help students practise one curriculum-aligned concept with instant feedback and explanations. Skill Align uses practice skills to organise questions by year level, subject, strand, and curriculum focus.
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.

Australian Curriculum-aligned science coverage across biological, chemical, physical, Earth and space science, and science inquiry skills, with visual sample questions available through the Year 7 science demo.
Practice sessions include exercise mode for instant feedback, test mode for delayed results, and parent review when the student signs in through a managed account. Skill Align treats practice questions and exercise questions as the same learning workflow: students answer curriculum-aligned questions, review explanations, and move between exercise mode and test mode.
Start with the public sample questions
to check the question style, then use the curriculum coverage page to choose a topic that matches the student's current classwork.
Preview question styles
Visual science foundations: Students inspect classification keys, food webs, particle models, force arrows, Earth-Sun-Moon diagrams, and simple graphs where the visual evidence matters.
Year 7 science strands: Samples cover biology, chemistry, physics, Earth and space science, and inquiry without turning the page into a generic subject directory.
Evidence-based explanations: Each item keeps the answer choices, diagram, and explanation aligned so students can see why one option is best supported.
Suggested first practice steps
Preview the public sample practice and exercise questions before creating a saved student session.
Choose one focus area that has already been introduced at school.
Use exercise mode for immediate explanations, then test mode when the student is ready for delayed feedback.
Can students try year 7 science practice questions australia before subscribing?
Yes. Public sample pages let visitors preview curated Skill Align questions without creating a saved student test record.
Does Skill Align replace school lessons or tutoring?
No. Skill Align is designed for structured practice after students have learned topics at school or with a teacher.
Are practice questions and exercise questions the same on Skill Align?
Yes. Families may search for either wording; Skill Align uses one curriculum-aligned practice page for both practice questions and exercise questions.
Can parents choose only one subject?
Yes. Skill Align uses subject-based access, so families can start with the year level and subject the student needs now.
Skill Align independently prepares practice coverage aligned to Australian curriculum learning areas where mapped. It is not affiliated with or endorsed by ACARA or state curriculum authorities.
