FINAL Clues from Our SPRING Secret Site
- Clues from Krystal:
- We have been starting to see our first
migratory spring birds. The first bird we seen was a pine grosbeak. We seen it on 3/7/99. The second bird we
seen was the Bald Eagle. The Eagle was seen about 5 miles up the river. We seen it on 3/26/99. The third bird
we seen was a common Redpoll. We seen it on 3/28/99. Both the grosbeak and the redpoll we seen at our birdfeeders."
- Clues from Sheila:
- "Joy and Shauna saw a camp robber (gray jay) carrying a stick in its mouth. We also saw ravens sitting
in their nest up the road last week (April 6th)."
- Clues from the teacher:
- "Last week we had our spring migrate-through
birds: the snow bunting!!!! The kids couldn't find them. I said, 'No, they're out there. Look harder.' (They were
RIGHT NEXT to the school on the ground). I said, 'Can't you see them? They're eating!' Finally Shauna said, 'OH!!
OH!! They eat on the ground because they are camouflaged to the snow!'"
- We are expecting our tulips to peek through the ground around the end of May.
- Here are our sunrise and sunset times so you can figure our photoperiod:
Confused Between "Phenology Data Exchange" and "Mystery
We hope this explanation will clarify any confusion between these 2
Phenology Data Exchange
This activity began last fall, and the spring component began in January. It is a year-long data collection project.
Students collect data about seasonal changes in plants & animals. Once each month they measure the sun's shadow,
photoperiod and temperatures. We post a "Data Collection Reminder" each month, 1 week before the data
is to be collected. As mentioned above, one "Secret Site" is chosen each season, and clues are sent with
the monthly reminder.
Extends from February to May, and is a global study of how photoperiod changes around the globe with the advance
of spring in the Northern Hemisphere. Each week, students collect their photoperiod every Monday. On Fridays, we
send the photoperiod from 10 Mystery Classes hidden around the world. In May, students are challenged to guess
the location of each Mystery Class.
The Next Phenology Data Exchange Reminder Will be Posted on March 12, 1999
