Year 6's

Hi,
i-buttons look like watch batteries. You can attach them to anything or just leave them on the ground. We did an experiment checking temperatures on a tree. We put the i-buttons in a bit of netting and taped them to the tree. We found the temperature really varied from the ground to a height of 1.5m. If you are a small animal you would feel the temperature differently to us. Here on KI in winter you would be a lot colder. I will take a picture for you of the i-buttons and I am going to buy some so we can try them when they arrive.
