Collecting
and recording air and soil temperatures in the tulip garden are scientific
ways to look at factors that influence the changing of the seasons.
Keeping track this data from year to year offers a wealth of material
for comparison and prediction.
Put your tulip data in a safe place and pull it out each year for study and
comparison.
