How Long Does it Take a Tulip to Grow? Look at the dates each of the following gardens was planted, and when the tulips emerged. Count how many days it took for the tulips to grow and fill in the answer: Location of Garden Date Planted Date Emerged # Days Vero Beach , FL 01/09/02 02/13/02   Cobble Hill, B.C., Canada 11/18/01 02/14/02   Lincoln City, OR 11/04/01 01/23/02   Fresno, CA 12/20/01 02/04/02   Croydon, England 09/28/01 02/04/02   Kingwood, TX 01/04/02 02/01/02   What do you think is causing the number of days to vary so much? Name an underlying factor that you think affects how long it takes for tulips to grow. How could you measure this factor in each garden, so the gardens can be compared? (In your answer, give examples from this year's gardens to show why counting days isn't helpful.) Copyright 2002 Journey North. All Rights Reserved.
