Exploring
Dew and Frost in Your Neighborhood
When,
where, and how do dew
and frost form? You become the scientist by making observations
close to home. Then think about what you noticed and what it might mean.
Try
This! Be a Windshield Watcher
- Look around
your house or street for a car that is usually left outside overnight.
- Every
morning for a week, observe the car's windshield. Do you see evidence
of dew or frost?
- At the
same time, gather weather data. Use the Windshield
Watch worksheet to document your findings.
Journaling
and Discussion Questions
- What patterns
do you notice?
- How would
you explain your observations?
- What conditions
seem to promote dew and/or frost?
- In what
ways do you think these natural events could affect monarchs in their
habitats?
