Lesson Outline


Join Sally-Ann Spence at British Antarctic Survey HQ where she will be learning about how ice cores are extracted and analysed to inform us more about climate change and our world in the past.

Subject Knowledge and Activity

We will be joined by scientists and experts who will tell us more about their experiences in the antarctic as well as what we learn from the research they do. In the BAS laboratories and freezer room, teaching will be put into a real-life context through exciting demos, recordings and animated infographics.

The lesson itself will follow the journey of a scientist from the clothes store in Cambridge all the way to Antarctica where they drill ice cores for analysis. We will follow the process step-by-step as the ice turns from solid to liquid to gas, focussing on what researchers look for in each part of the process.

Questions and answers

Our expert speakers will join us in the studio to answer your students’ questions. Click here to submit a question!
