When scientists conduct an experiment, they try to repeat it many times.
The more it's repeated, the more reliable the data. Imagine seeing Journey
North tulip test-gardens growing all around your community! Here's how to invite families to join in this international experiment.
the Groundwork: What Would Happen If . . .?
As a class, explore the idea of taking bulbs home and planting plots around
your town. Discuss these questions:
you think the tulips in all of these gardens would grow and bloom at
the same rate. Why or why not?
factors might make a difference? (Think about factors you considered
when you chose your school garden site.)
"rules" should we use for planting our gardens? How should
we gather our data in the spring?
- Send students
home with bulbs (1 or 2 each) and a letter for parents.
Families are welcome to participate
in Journey North.
gardens have been planted, give students time to discuss their experiences.
Then have each student draw a map of his or her home garden site. Maps
should show the following:
- the distance
from the garden to the house
- the location
of trees or other sources of shade
- the location
of pavement or other sources of heat
directions: north, east, south, and west
- any other
factors students feel are important
- In the
late winter and spring, have students report back to the class twice:
1.) when their tulips emerge and 2.) when their tulips bloom. Keep a
class chart. Challenge students to organize the data and try to make
sense of it. (Journey North News Updates will help them do this.)
- When your
class reports to Journey North, please consolidate the home garden data
rather than report each garden separately. For instance, you could report
average emergence and bloom dates. In the "comments" section
of your Field Data Report,
tell us the results of your community-wide experiment!
