    Open Awards Level 1 Certificate in Science (RQF)
    Open Awards Level 1 Award in Science (RQF)

    Topic Overview

    The Open Awards Level 1 Certificate in Science (RQF) is a vocationally-related qualification designed to introduce students to the fundamental principles of science and their practical applications. This course covers key areas such as biology, chemistry, and physics, with a strong emphasis on developing scientific skills through hands-on investigations. It is ideal for students who wish to build a solid foundation in science before progressing to further study or entering science-related careers.

    Throughout the certificate, you will explore topics like the structure of living organisms, chemical reactions, energy transfers, and the properties of materials. The course also focuses on scientific enquiry, including planning experiments, collecting data, and drawing conclusions. By the end, you will have gained essential knowledge and skills that are directly relevant to everyday life and the workplace, such as understanding health and safety in a lab or interpreting scientific information in the media.

    This qualification is part of the wider Applied Science suite, which prepares students for roles in sectors like healthcare, environmental science, and manufacturing. It also provides a stepping stone to Level 2 qualifications, such as GCSE Combined Science or BTEC Applied Science. The practical nature of the course means you will spend significant time conducting experiments, making it engaging and memorable.

    Key Concepts

    Core ideas you must understand for this topic

    • →Cells as the basic unit of life: Understand the structure and function of plant and animal cells, including key organelles like the nucleus, mitochondria, and cell membrane.
    • →Chemical reactions and equations: Learn to identify reactants and products, and write simple word equations for reactions such as combustion, neutralisation, and displacement.
    • →Energy stores and transfers: Know the different forms of energy (kinetic, thermal, chemical, etc.) and how energy is transferred between them, including the concept of conservation of energy.
    • →Forces and motion: Grasp Newton's laws of motion, including how unbalanced forces cause acceleration, and be able to calculate speed using distance/time.
    • →Scientific method: Master the steps of planning an investigation, including identifying variables (independent, dependent, control), taking accurate measurements, and evaluating results for reliability.

    Learning Objectives

    What you need to know and understand

    • Know the terms relating to light and sound. Be able to identify different types of waveKnow about light waves.Recognise the role of light waves in imaging.Know about sound waves
    • Define basic terms such as wavelength, frequency, and amplitude.
    • Identify transverse and longitudinal waves.
    • Describe how light travels and interacts with objects (reflection, refraction).
    • Explain how sound is produced and travels through different media.
    • Recognise the function of lenses in forming images.

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Knows terms relating to light and sound (e.g., reflection, refraction).
    • Identifies different types of waves (transverse, longitudinal).
    • Understands the role of light waves in imaging.
    • Recognises properties of sound waves (pitch, amplitude).
    • Award credit for correctly labelling a diagram of a wave with wavelength and amplitude.
    • Accept clear distinction between transverse and longitudinal waves with examples.
    • Demonstrate understanding that light travels in straight lines and can be reflected.
    • Show ability to describe the role of the eye or a camera in capturing light to form an image.
    • Provide evidence of knowing that sound requires a medium to travel.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Use diagrams to explain wave properties.
    • 💡Remember that light travels faster than sound.
    • 💡Practise labelling wave parts like wavelength and amplitude.
    • 💡Use clear, labelled diagrams to support answers about wave properties.
    • 💡Memorise key differences between light and sound waves (e.g., speed, medium).
    • 💡When describing imaging, refer to how light enters the eye or camera, not just the result.
    • 💡Practice using correct scientific vocabulary in short-answer questions.
    • 💡Always use correct scientific terminology in your answers. For example, say 'diffusion' instead of 'mixing' and 'evaporation' instead of 'drying up'. This shows the examiner you understand the concepts.
    • 💡When describing experiments, mention the control variables and why they are kept the same. This demonstrates your understanding of fair testing, which is a key assessment objective.
    • 💡For calculation questions, show all your working out, even if you think it's simple. You can gain marks for correct method even if the final answer is wrong. Always include units in your final answer.

    Common Mistakes

    Common errors to avoid in your coursework

    • Confusing reflection and refraction.
    • Thinking sound travels faster than light.
    • Mixing up transverse and longitudinal waves.
    • Confusing reflection with refraction.
    • Thinking sound can travel through a vacuum.
    • Incorrectly identifying the amplitude on a wave diagram.
    • Believing all waves require a medium (e.g., thinking light needs a medium).
    • Misconception: 'All metals are magnetic.' Correction: Only iron, nickel, cobalt, and their alloys (like steel) are magnetic. Many metals like copper, aluminium, and gold are not magnetic.
    • Misconception: 'Energy is created or used up.' Correction: Energy cannot be created or destroyed; it is only transferred from one store to another. For example, a battery doesn't 'use up' energy—it transfers chemical energy to electrical energy.
    • Misconception: 'Plants get their food from the soil.' Correction: Plants make their own food through photosynthesis using sunlight, carbon dioxide, and water. Soil provides water and minerals, but not the main energy source.
