STEM projects with connected science, technology and mathematics

A STEM project brings science, technology, engineering and mathematics into a shared problem. The connection is useful when pupils can explain which knowledge informed a decision. This guide develops a delivery-container challenge and shows how to keep the learning visible, practical roles inclusive and evaluation tied to evidence.

Choose a problem with clear constraints

Ask pupils to design a container that carries a set of classroom objects between two tables without losing or mixing them. Agree the contents, route and available materials. Define success before construction begins, including practical requirements such as opening the container and returning materials to storage.

Identify the subject contributions

Mathematics can support measuring and comparing dimensions; science can inform material choices; design and engineering can guide construction and testing. Technology should serve a purpose if included, such as recording a test or controlling a device. Do not add a screen merely to make an activity appear more advanced.

Teach what pupils need

Provide brief practice with the measurement or joining method required. Let teams test sample materials and record observations before choosing. Rotate roles so that design ideas, practical work and recording are shared. Offer adaptations to tools and response methods while retaining meaningful decisions for every learner.

Test, revise and explain

Use the same contents and route for each test, keeping loads modest and movements controlled. Record what happened and identify one change supported by the evidence. Older pupils can compare material use or repeatability; younger pupils can demonstrate how a change helped. Choose resource sets with components that can be reused and instructions that explain their purpose. Assess whether pupils connect a design feature to knowledge from a subject and to a test result. A successful final presentation includes a limitation or remaining question as well as the part that worked.

Reuse the problem with a changed constraint

A later session can revisit the same design with a different user or a slightly altered requirement. For the delivery container, pupils might need to make the opening easier to operate or fit a new arrangement of objects. Keep the earlier prototype and test record available. Ask which existing knowledge remains useful and what new information is required. This makes transfer visible and reduces the pressure to produce a completely new themed project every time. A short design review can separate the original success criteria from the revised ones, helping pupils understand why a previously successful solution may now need adaptation.

Action checklist

  • Agree constraints before building
  • Name each subject’s contribution
  • Practise necessary techniques first
  • Link revisions to observed results

Common questions

Must a STEM project include a digital device?

No. Technology should have a useful role in the problem; meaningful connections between knowledge, design and testing matter more than adding a screen.

Alphabet and phonics activities for purposeful practice

Letter recognition and phonics serve related but different purposes. These activities help staff choose resources for listening, linking sounds to letters and blending words, while keeping practice consistent with the school’s teaching sequence. They also show what to notice when a child needs a smaller step.

Ancient Egypt: evidence, everyday life and careful timelines

Ancient Egypt offers opportunities to explore how historians build accounts from objects and records. A carefully chosen enquiry can include work, writing, beliefs and everyday life. Use this guide to select evidence, keep a long historical period in perspective and give children meaningful ways to explain what they have discovered.

Ancient Greece: learning through objects and evidence

An ancient Greece topic becomes more useful when pupils ask how we know about people’s lives. Work from objects and clearly identified sources, compare places and experiences, and keep myths in their own literary context. A small enquiry can develop historical reasoning alongside careful observation and discussion.

Around the world: respectful place and culture enquiries

Learning about the world works best through specific people, places and questions. This guide uses everyday experiences such as journeys and play to help children compare thoughtfully. It supports resource choices that show variety within communities and avoids asking one child to represent an entire country or culture.
