Today's Report Includes:
Presidential Data

|
Mrs. Berger's 5th Grade Class |
Remember this information was recorded for Monday, February 21. So, if you had that day off, remember to collect your local sunrise/sunset data for Monday as you normally do. (This week's sunrise/sunset times are provided at the end of this report)
Seeing the Light?
As you know, Journey North tracks several migratory animals each spring. Why do you think we are also tracking changes in daylight? Over the next months, all the animals you track and all the signs of spring you witness will be related to daylight in one way or another.
To help you discover these connections, this would be a good time to look at the:
- Seeing the Light Lesson ( or page 93 of the printed Teacher's Manual)
Try This!
- Select one of the Journey North migratory species.
- Find out where this animal fits in the food web. (What does this animal eat,
i.e.what is its prey? What is it's prey's prey? What plants does the prey eat?, etc.)
Go back through the food web until you reach the sun as the source of food energy
for this system.
- Draw a diagram of your animal's food web.
- Next, think about ways this food web changes during the seasons.
- Now, see if you can answer:
Challenge Question #1
"How do seasonal changes in photoperiod affect your animal's food web?"
(To respond to this question, please follow the instructions below.)
