How
are plants affected by climate and the seasons?
In this
large experiment students across the Northern Hemisphere track the growth
of the same plant as the season changes from winter to spring.
They discover how temperatures,
sunlight, geographic location, and other variables influence
plant growth — and the full array of seasonal changes that take
place in the springtime. These observations set the stage for
a better understanding of the impact of a changing climate. >>>
