Bringing back glass

A set of activities to help children explore the importance of glass in everyday lives, for scientific experimentation, problem-solving and in technology


We hope that this resource will help teachers to inspire future generations of young scientists. After all, "We are only limited by our imaginations!"

The Worshipful Company of Glass Sellers of London

Celebrating the United Nations International Year of Glass 2022, by 'bringing back glass into the primary classroom', the Primary Science Teaching Trust (PSTT) is delighted to be working with The Worshipful Company of Glass Sellers of London to share this resource with primary science educators.

Background Science

In this free to download booklet, you will find 15 activities designed to support delivery of engaging science lessons that enable Early Years and primary school children (from 3-11 years) to explore the properties, uses and benefits of glass and to engage in meaningful and relevant investigative science.

The activities cover a wide range of primary science topics including:

    • Materials & their suitability for different purposes
    • Light
    • Sound
    • Plant germination & growth
    • Soil
    • Water cycle
    • Animal adaptation (birds)
    • Habitats (the Arctic)

Possible learning outcomes for each activity have been linked to the UK primary curricula so that educators can see where an activity might fit into their planning. Using easy to source materials, many activities are also suited to use in themed science days, science weeks, or for science or STEM club activities.

Symbols indicate the types of enquiry and the skills that can be developed through each activity. These symbols could be displayed in the classroom and can be downloaded here: Enquiry types and Enquiry skills.

All the activities have been written by PSTT College Fellows.
