Logs of Straw - Dendrocronology
Dendrochronologists use tree rings to go back in time to learn more about past climate. Using straws to recreate tree rings, you can learn how dendrochronologists work.
Looking for Wild Elements
In this activity, students will explore local places with wild elements, such as wildlife refuges. Students also will create maps showing spatial relationships between wild places and school, and they will find creative ways to record experiences.
Making Caves: How Solution Caves Form
Caves form through a variety of natural processes depending on their local geology and climate. Flowing lava, melting ice, dissolving rock, and crashing waves are the major processes that form these wondrous environments. In this activity, students will observe a model of how the most common type of cave — solution caves — form.
Per student or small group:
• 4 ounces of modeling clay
• Sugar cubes (3-6 per cave)
• See-through bowl (cutting the top off a 2-liter bottle works well)
Mapping a Refuge
A refuge is a place where you can record observations of seasonal changes to plants, trees, and wildlife. You can use GPS (global positioning system) data to mark an observation spot and record your observations. Then, if you can, visit the same national wildlife refuge during other seasons in the year to document changes in the natural world.
Monitoring Life in the Rocky Intertidal Ecosystem
The five national marine sanctuaries along the West Coast monitor the health of the rocky intertidal ecosystem. One way of doing this is to collect data on the relative abundance of the organisms living in that ecosystem. Since this is such a big task, the national marine sanctuaries are training students in how to follow standardized protocols to help with the monitoring. The information collected is added to an online database that the sanctuaries use to collect baseline data and track long-term changes in the environment. This activity will allow you to learn the sampling techniques used in the field by these citizen scientists who participate in LiMPETS.

Pretend to be a biologist as you 'discover' a new mollusc species and work to determine it's characteristics and habitat.
Plant an Ozone Monitoring Garden
Students can monitor local ozone by looking in their neighborhoods for ozone-injured plants or establishing similar gardens outside their schools or in their backyards.
Sea Level and the Terrapin
This activity from the Environmental Protection Agency will give children the opportunity to see how changes in sea level effect coastlines, animal life, and community development.
