Physical Features of the Earth ()
Students assemble jigsaw puzzles in their classroom which provide them information about the different types of rock and the rock cycle. At a field trip site near the Arches National Park Visitor Center, students examine a limestone layer to find fossils, and make clay models of faulting after putting their hands on the actual surface of an exposed fault plane. They explore and model the formation of arches, and learn the names and depositional histories of the rock layers surrounding them. Back in the classroom, a mapping activity introduces the ultimate source of the rock cycle: plate tectonics.
Physical and Chemical Changes in Matter ()
In the classroom, students explore the difference between physical changes and chemical changes in matter. On the field trip, they go for a hike and observe these changes taking place in the natural world. They learn about particulate matter in the air, discuss what types of changes created these particulates and discover how scientists are measuring them. They act out the chemical changes that are destroying ozone in the upper atmosphere and see how scientists are measuring ozone recovery. Back in the classroom, students mix household items and predict the type of resulting reactions.
Plant Adaptations (download PDF)
Students explore genetics using desert plant adaptations, riparian plant adaptations, and a few desert plants and animals adapted to nighttime activities. Their field activities include: rough observation and data collection, a clue trail, plant keys, story, and a smelling game. In classroom activities, students take on the identity of a desert plant or animal, and later create an imaginary plant with adaptations for survival in its imaginary environment.
