Cool Pots - Primary Global upd8

This activity provides a practical context to explore thermal insulation and changes of state at primary level. Families living in Sudan find that due to the warmer climate fruit and vegetables tend to not stay fresh for long. In order to solve this problem they use a clay pot (zeer pot) refrigerator to help delay the deterioration of fresh produce. This problem is introduced by a presentation, accompanied by a short video showing how a zeer pot works. Children are then challenged to work scientifically to investigate how long it takes an ice cube to melt in a mini ‘cool pot’ compared with an uninsulated pot. This resource has been produced by the Association for Science Education in partnership with Practical Action as part of the Global Learning Programme.
