You have already examined your tulip bulb; weighed, measured, and cut it open. Now learn more about each part of the bulb. Use this step by step slideshow to learn how each part has a unique function for this plant storage structure.
Your tulip bulbs have arrived and you're going to bury them in the garden. But wait! What's a bulb? Let's take a look. A bulb contains everything needed for winter survival and spring growth. Explore your bulbs and as a scientist, predict what its parts will become when spring arrives.
With your test gardens, you can contribute scientific information by monitoring connections between plant growth and climate. What discoveries will be made from the data collected by Journey North citizen scientists?
Springtime events occur at different times in different places. Track Test Gardens to discover how different climate conditions affect plant growth.
Seasonal change is all around us. Children see it in the length of a day, in the appearance of a flower, in the flight of a butterfly. Journey North is a free, Internet-based program that explores the interrelated aspects of seasonal change. Citizen scientists across North America share their own observations of migrations and other signs of the seasons.
