The Primary Science Teaching Trust (PSTT) Trail books encourage teachers to use the outdoors and the magnificence of the natural world to inspire awe and wonder, whilst at the same time appreciating the ingenuity of humans and the interaction between the two.
Let’s Go! STEM Trails builds on the success of Let’s Go! Science Trails but widens the scope of subjects and curriculum areas. Once again, a wealth of collective expertise has been used to create an outdoor learning resource that can be used by teachers in any local environment.

There are no seven wonders of the world in the eyes of a child. There are seven million.

Walt Streightiff

How do the trails work?

There are 29 Trails in the book.

Each Trail is based on a particular topic or area and the locations chosen will allow children to see real-life examples of these and focus on how everyday problems have been solved by scientists, designers, engineers etc.

The Trails are set out simply and clearly under the following headings:

Introduction                                   Resources and Preparation

Concepts Explored                         On the Trail

Key Vocabulary                              Key Questions

Scientific Skills                               Back in the Classroom


The book also includes:

  • A photocopiable Health and Safety Checklist
  • An extensive glossary of scientific, maths and engineering and technology terms

Planning a whole school STEM Day?

There are Trails and projects to inspire all ages. Here is a (brief) example of one trail you might choose –

Historical Buildings

Location: Any historical building (it could be very close to your school).

For example, a church, a house, a museum, a cathedral, a castle.

Introduction: Children will look at historical buildings and compare them with modern ones. They will look at both the materials and the shapes used and think about how technology and engineering has changed.

Materials:  Can be used in a variety of ways.

Have similarities and differences.

Are chosen for specific purposes, depending on their properties.

Shapes: Compare and classify geometric shapes based on their properties and sizes.

Skills: Observe, measure, record, collect data, present results, draw conclusions based on evidence.

Preparation: Look at modern day equivalents of the building you are visiting. Ensure children have a good knowledge of 2D and 3D shapes. What shapes are used in the modern-day building?

Resources: Digital cameras, clipboards, paper and pencils

On the Trail:

  • Look at a building of interest and discuss both the construction materials and the shapes that can be seen in use. Look at the roof, walls, windows, doors, door handles and other small features.
  • Work in small groups. Each group focuses on one common material and one shape and identifies and records information.
  • Ask key questions (a list is provided), such as: How have building materials changed or developed through time?

All of the trails in the book have been tried and tested by groups of teachers across the UK.

Children’s enthusiasm is overwhelming. Children are keen to be out on a trail again – they are driving the project!

Over the year, he confidence in teaching staff to go outside and try different Trails has increased.
