Alloys and Metals, Polymers and Plastics
This topic introduces processes for making household products from plastics, polymers, metals, and alloys. It covers forging, smelting, die-cutting, casting, and recycling, along with practical participation in making products.
Assessment criteria
Topic Overview
The Open Awards Entry Level Certificate in Science (Entry 2) (RQF) is a foundational qualification designed to introduce students to key scientific concepts in biology, chemistry, and physics. It focuses on developing basic scientific skills, such as observing, measuring, and recording data, while building understanding of everyday science. This qualification is ideal for students who are new to science or need a stepping stone to higher-level study, as it covers essential topics like living things, materials, and forces in a practical, accessible way.
The course is structured around three main units: 'Living Things and Their Environments', 'Materials and Their Properties', and 'Physical Processes'. In the biology unit, students explore the characteristics of living organisms, habitats, and simple food chains. The chemistry unit introduces common materials, their properties, and changes like melting and dissolving. The physics unit covers basic forces, electricity, and light. Assessment is through portfolio-based tasks and practical activities, allowing students to demonstrate their understanding in a supportive environment.
This qualification matters because it provides a solid foundation for further study in science, whether at Entry 3, GCSE, or vocational courses. It also helps students develop critical thinking and problem-solving skills that are valuable in everyday life and future careers. By the end of the course, students should be able to identify common scientific phenomena, carry out simple investigations, and communicate their findings clearly.
Key Concepts
Core ideas you must understand for this topic
- →Living things: Understand that all living things (plants and animals) need food, water, and air to survive, and that they grow, reproduce, and respond to their environment.
- →Materials: Recognise common materials (e.g., wood, metal, plastic, glass) and describe their properties (e.g., hard, soft, flexible, waterproof). Know that materials can be changed by heating, cooling, or mixing.
- →Forces: Identify pushes and pulls as forces that can change the shape, speed, or direction of an object. Understand that gravity is a force that pulls objects towards the Earth.
- →Energy: Know that energy comes from different sources (e.g., sun, food, batteries) and is used to make things happen, such as light from a bulb or movement from a motor.
- →Scientific enquiry: Be able to ask simple questions, make predictions, carry out fair tests, and record observations using tables or charts.

Assessment Criteria
Key criteria assessors look for in your portfolio
- States processes for making products from new and recycled plastics.
- Identifies household products made from metals and alloys.
- Describes forging, smelting, die-cutting, and casting techniques.
- Participates safely in making household products from given materials.
- Reviews own contributions and suggests improvements.
Assessment Guidance
Guidance for achieving higher grades
- 💡Use diagrams to explain processes like injection moulding.
- 💡Practice identifying materials in everyday objects.
- 💡Work collaboratively in practical tasks and reflect on teamwork.
- 💡When describing properties of materials, use specific vocabulary like 'transparent', 'brittle', or 'conductive' rather than just 'good' or 'bad'. This shows deeper understanding and can earn you higher marks.
- 💡In practical tasks, always explain why you are doing each step (e.g., 'I am measuring the temperature every minute to see how fast the ice melts'). This demonstrates your understanding of fair testing and variables.
- 💡For food chains, always start with a producer (plant) and use arrows to show the direction of energy flow. Remember: arrows point from the food to the eater, not the other way around.
Common Mistakes
Common errors to avoid in your coursework
- Confusing forging with casting.
- Not recognising the difference between thermoplastics and thermosets.
- Forgetting safety precautions when handling materials.
- Misconception: All metals are magnetic. Correction: Only some metals (like iron, nickel, and cobalt) are magnetic. Many metals, such as aluminium and copper, are not attracted to magnets.
- Misconception: Plants get their food from the soil. Correction: Plants make their own food through photosynthesis using sunlight, water, and carbon dioxide. Soil provides water and minerals, but not the main food.
- Misconception: Electricity flows out of a battery and is used up. Correction: Electricity flows in a complete circuit; the battery provides energy to push electrons around the circuit, but the electrons themselves are not used up.
