If you can, try to collect materials throughout the year for use during British Science Week.
You never know what leftover items could come in handy, from plastics bottles and pieces of wool, to food colouring and clay.
Alternatively, check to see whether there is a scrap shop/store/club open in your local area. These places are often membership based and can be a brilliant, inexpensive or free resource for card, fabric and other bits of material. Salvaged materials can be turned into spaceships, trees, sea creatures and more. You name it – the kids will think of it! Look at https://www.reusefuluk.org/ to find a UK directory of scrap stores.
Take photographs that you feel represent ‘Change and adapt’ and share these with your students. Start a discussion around the photos and raise their level of understanding about the changes happening all around us, in plants, building structures and so on. The more colourful, the better!
The photos can be a reference point for future activities, for example a version of the guessing game ‘I spy’, where you can describe your observation of a change or adaptation and the students can try to guess it.
Collect story books and/or reference books around the theme of ‘Change and adapt’ to create a themed library.
