This activity (located on page 3 of the PDF under GPS: Temperate Rain Forest Activity) is a full inquiry investigation into tree growth rates.

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.

In this archaeology-related activity, learners build their own time capsule and choose a storage location and a date to reopen it.

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

In this activity, learners work in groups to create a time line representing significant moments in their lives.

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 activity, learners will create their own coral polyps - the basis for a coral reef.

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.

This fun and simple hands-on astronomy activity illustrates the value of supernovae in the universe.

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

In this activity, learners create their own archaeological profiles.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.
