In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most. Then, learners estimate the size of a Triceratops and T.

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 activity, learners observe live fish in tanks to consider how their body structures are related to their behaviors and habitats.

This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

In this activity (located on page 4 of PDF), learners gain insight into the actual size of dinosaurs and practice making estimations and measurements.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this activity, learners model, on a human-sized board game, how changes in water temperature may affect fish distributions and, ultimately, fisheries.

Using a real-size sketch of a baby elephant's footprint, learners estimate, measure and record the width (diameter) and outside edge length (perimeter or circumference) of the footprint.

In this story time program, young learners listen to the Dr.

Learners construct a bird feeder from re-used materials. After hanging their feeder, they keep a journal about what birds visit the feeder.

In this outdoor activity, learners first explore lizard feeding behavior by creating a "lizard rig" to dangle different objects in front of live lizards and see which objects the lizards try to bite.

In this activity, learners will investigate how shorebirds and seabirds are extremely vulnerable to changes in their environment, whether human-induced or otherwise.

In this activity, learners will explore how the human brain interprets environmental stimuli.

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.

In this activity (on page 2 of PDF under GPS: Sea Turtles Activity), learners will model how a sea turtle population changes over time, from eggs to adults, using puffed rice.

In this outdoor biology and math activity, learners estimate the size of a population of organisms too numerous to count.

In this outdoor game, learners simulate a herd of deer trying to survive in an area called the "home range." Learners explore the concept of "carrying capacity"—what size population of an organism can

In this activity, learners investigate the sense of hearing and plan and conduct their own experiments.
