Students need to measure temperature and bud break from February 1 until April 1. Minimum and maximum temperatures are recorded daily with a min-max thermometer loaned to the school by the Department of Forestry. Bud break is checked weekly and growth of the bud is measured with a standard ruler.
Students prepare charts of data and calculate growing degree-days.
Data for all participating schools will be posted on the web by November 15, along with questions about global climate change.
