Tracking Change in Seasons and Climate Around the Globe
In this international science experiment, students across the northern hemisphere plant tulip bulbs in their Journey North Test Gardens each fall. When the plants emerge and bloom, children announce that spring has arrived in their part of the world.
One garden at a time, the relationship between climate, geography and the arrival of spring is revealed. Students make observations in their own hometown, and watch the wave of spring as it moves across the globe.
This project enlists the help of students as citizen scientists to monitor seasonal change in a scientific way. As plants develop and grow they reveal the effects of the local climate. Over time, the timing of plant growth can be used as an indicator of climate change. Students contribute valuable observations to a long-term database.
Join the Fun!
This fall, plant your own Journey North garden so you can proclaim the official arrival of spring in your community. Children of all ages can participate. How will the arrival spring compare to earlier years? Join the experiment to find out!
