In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.

In this interactive activity, learners analyze seashells to explore phylogeny and evolution. Learners identify similar and dissimilar seashells to create a phylogenetic tree.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

Coins are everyday objects which tell a lot about the people who use them.

Birds' beaks are designed to allow birds to get the most of whatever food they need. In this activity, learners get an idea of how different beak shapes suit different food sources.

In this activity, pairs of learners will create two make-believe dig sites by burying chicken bones in plaster of Paris--a powder that hardens when wet.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en libros de consulta o en línea.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

In this activity about vision and optical illusions, learners conduct a simple test to demonstrate how our eyes create "afterimages." Learners stare at a black cardboard bat for at least 30 seconds an

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

In this activity, learners examine the culture and history of the tomb site.

In this activity, learners create their own archaeological profiles.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery

In this activity (page 2 of PDF under GPS: Alligator Habitat Activity), learners will study the adaptations different fish species have developed to survive in their habitats.

In this activity (on pages 30-36), learners simulate a dig for ancient pollen, to experience how paleobotanists study fossilized pollen in rocks to learn about early geological and climatological even

In this activity, a group of learners work collaboratively to design and construct a paper model showing the evolution of an environment through multiple stages, from prehistory through the modern cit

In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.
