    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for correctly naming and sequencing the planets from the Sun, distinguishing between terrestrial and gas/ice giants.
    • Look for clear diagrams or models of the solar system that show relative distances or scaled sizes.
    • In the habitable planet simulation, assess the inclusion and justification of essential factors: liquid water, atmosphere composition, temperature range, and protection from radiation.
    • When assessing telescope design, credit accurate labelling of optical components and explanation of how light is focused to form an image.
    • In space probe design, reward evidence of research into real missions and the selection of appropriate instruments for the stated goal.
    • For human survival discussions, accept well‑reasoned arguments addressing microgravity countermeasures, radiation shielding, and life support recycling.
    • Award credit for accurately ordering the planets from the Sun and including the asteroid belt and Kuiper Belt in a diagram or model.
    • Award credit for explaining at least three key factors that make Earth habitable (e.g., liquid water, atmosphere, magnetic field) and linking them to the planet simulation design.
    • Award credit for demonstrating the light path through a refracting or reflecting telescope with correct component labeling in a constructed model.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Use labelled diagrams to illustrate planetary orbits, telescope ray paths, or space probe components, as visual evidence often carries high marks.
    • 💡In design tasks, always justify material and component choices by linking them to the specific environmental conditions of the mission.
    • 💡Practice explaining the ‘Goldilocks zone’ concept using Earth as a reference to show understanding of life‑sustaining conditions.
    • 💡When describing telescope operation, include a ray diagram and state the magnification formula, even if not explicitly required.
    • 💡Revise key facts about the solar system (planet names, order, basic features) as these are frequently tested in short‑answer questions.
    • 💡When designing a telescope, justify your choice of optical components by comparing properties like focal length and aperture, referring to real-world examples such as the Hubble or Galileo's telescope.
    • 💡For the planet simulation, use digital tools (e.g., Universe Sandbox) or physical models with clear scale and labeling, and include a written rationale for each life-sustaining feature.
    • 💡In space probe design, consider constraints like power source (solar vs. RTG), communication delay, and durability; reference missions like Voyager or Perseverance to show understanding of trade-offs.
    • 💡For assignments requiring diagrams (e.g., solar system, telescope, space probe), always label key components clearly and use annotations to demonstrate your understanding.
    • 💡When explaining Earth's life-sustaining characteristics, link each feature directly to a specific life requirement (e.g., 'the ozone layer protects DNA from UV damage').
    • 💡In the planet simulation task, present your design as an evidence-based proposal: state each chosen condition and explain why it is critical for life as we know it.
    • 💡For the space probe design, structure your response to address each marking criterion explicitly—mission goal, probe features, how each feature meets the goal, and a labelled diagram or model.
    • 💡Always show your working in calculations, even if you use a calculator. This allows examiners to award partial credit for correct methods even if the final answer is wrong.
    • 💡When writing conclusions, refer back to your hypothesis and explain whether your results support it, using specific data from your experiments.
    • 💡In practical assessments, ensure you label all diagrams and tables clearly, and include units in all measurements.

    Common Mistakes

    Common errors to avoid in your coursework

    • Confusing the order of planets or omitting the asteroid belt, leading to incorrect understanding of solar system layout.
    • Assuming that a planet can sustain life if it simply has water, without considering atmospheric pressure or magnetic field protection.
    • Neglecting to account for structural stability and alignment when building a telescope, resulting in a non‑functional instrument.
    • Believing that astronauts can survive in space with only an oxygen supply, ignoring temperature extremes and radiation dangers.
    • Misunderstanding the one‑way nature of most space probes, expecting them to return to Earth like manned missions.
    • Confusing the order of planets, especially placing Mars and Earth or Saturn and Jupiter incorrectly.
    • Assuming that a planet's distance from the Sun is the sole factor for habitability, neglecting atmospheric composition and magnetic fields.
    • Failing to include a stable orbit around a star in a planet simulation, leading to an unrealistic planetary system.
    • Believing that telescopes only use mirrors or only lenses, without recognizing the variety of designs like refractors and reflectors.
    • Learners often confuse the order of planets or misclassify Jupiter as a terrestrial planet due to its size.
    • Many learners incorrectly assume that Earth's ability to sustain life is solely due to its distance from the Sun, overlooking factors like the magnetic field or plate tectonics.
    • When designing telescopes, students frequently place lenses in the wrong order or neglect to explain the role of the eyepiece in magnifying the image.
    • In space probe designs, a common mistake is focusing on aesthetics rather than scientific function, such as including unnecessary features without justification of power, data transmission, or propulsion.
    • Misconception: 'Accuracy and precision mean the same thing.' Correction: Accuracy refers to how close a measurement is to the true value, while precision refers to how consistent repeated measurements are.
    • Misconception: 'A risk assessment is just a formality.' Correction: Risk assessments are crucial for identifying hazards and implementing control measures to prevent accidents.
    • Misconception: 'All scientific data should be presented in a bar chart.' Correction: The choice of graph depends on the type of data; line graphs are for continuous data, bar charts for discrete data.
