Microorganisms play a vital role in the high desert ecosystem.
Lichens and Soil Crusts
• Balanced Rock Picnic Area (best location)
• Windows Primitive Loop (behind North Window)
• La Sal Mountains Overlook (only for Lichen station)
Each station is designed for up to 15 students and requires one hour and one instructor. For larger groups we recommend dividing your group and teaching stations simultaneously, then having students switch stations.
Optional Prep Activity (to be used if students are unfamiliar with microorganisms): Mystery Photographs - Worms, hairy hotdogs and pizzas! These are what some microorganisms look like under the microscope. Work in teams, and match the photographs to their descriptions.
1. Lichens Up Close - Dramatize the roles and structure of lichens living on the sandstone, and scientifically investigate whether they grow better in sun or shade.
2. Cryptos Up Close - Take a close-up look at the structure and function of biological soil crust, and use scientific methods for measuring soil bump heights.
Extension Back to School (assessment activity):
Tell Me About It - Students work together to create brochures to educate others on the microscopic life found at Arches National Park.
