1. The diagram highlights the cell membrane around a cell. Which function best matches the highlighted structure?
The cell membrane forms the boundary of the cell and helps control movement of substances into and out of the cell.
Try Australian Year 8 science practice questions and exercise questions with visual explanations. Start with public sample questions across cells, particles, plate tectonics, energy transfer, body-system data, and fair-test reasoning before opening the no-login demo.
Year 8 Science includes 155 practice skills across Science as a human endeavour, Science inquiry, and Science understanding.
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.
These sample questions are visible on the page before login. They show Year 8 cells, particle models, plate tectonics, energy transfer, body-system data, and inquiry graphs before opening the demo.
The cell membrane forms the boundary of the cell and helps control movement of substances into and out of the cell.
In a chemical change, atoms are conserved but rearranged into new substances. The particle model shows different groupings after the reaction.
The arrows point toward each other and one plate bends beneath the other, which is a convergent boundary with subduction.
A torch is designed to produce light. Some energy is also transferred as heat, but light is the intended useful output.
The highest point on the graph is during exercise, showing breathing rate increases when muscles need more oxygen.
The tallest bar is foil, so in this dataset foil had the longest cooling time and kept the water warmest for longest.
Year 8 science practice should make cells, particles, plate movement, energy transfer, body-system data, and fair tests feel structured rather than guessable. These examples preview that visual reasoning before the no-login Year 8 Science demo.
These related pages help students and parents move from this search result to the exact year, state pathway, or subject they need.
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 8 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.
These examples are not the full topic list. Use the curriculum coverage page for the complete mapped pathway.
Year 8 students consolidating junior secondary science, including families looking for visual Australian Curriculum-aligned revision at home.
Yes. Public sample pages let visitors preview curated Skill Align questions without creating a saved student test record.
No. Skill Align is designed for structured practice after students have learned topics at school or with a teacher.
Yes. Families may search for either wording; Skill Align uses one curriculum-aligned practice page for both practice questions and exercise questions.
Public samples are free before sign-in. Regular full subject access uses a parent-managed account with included access to start and an optional monthly subject subscription when more practice is needed. Exam packs are separate one-off PDF purchases.
