Built for the Desert
The saguaro cactus has an amazing ability to survive in a harsh environment. Learners identify the many adaptations for desert life that the saguaro employs. They look at each part of the saguaro and determine what role it plays in the...
Desert Discovery
Saguaro Parts
Young biologists identify the basic structures of a saguaro cactus. They study the functions of each of the structures, and label them on a picture of a saguaro cactus embedded in the plan. This simple, and easy-to-implement...

Invasion of the (Cactus) Booty Snatchers
Students, in groups of four,identify and analyze relationships among birds within a population, a community and an urban ecosystem. They fill out, while they're completing their experiments, a Populations of Birds Student Data Sheet.
Desert Discovery
Life Cycle of the Saguaro
Third graders make books which illustrate the growth and development of a saguaro cactus from its beginnings as a seed all the way through its death. They trace the life cycle of the saguaro, identify each of the stages in its life, and...

Science: Putting Down Roots
Fourth graders, in small groups, observe plants and note their characteristics. After drawing pictures of the plants, including their roots systems, they hypothesize in which environments the plants would best thrive. Finally, 4th...
Curated OER
Desert Water Keepers
Students experiment with models to find how plants survive in the desert environment. In this plant mechanisms activity, students make leaf models to understand how leaves conserve water. Students collect cactus in bags and observe the...
