In this activity, learners will simulate the interactions between a predator population of gray wolves and a prey population of deer in a forest.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

This activity (on pages 35-43) lets learners analyze a "herd of elk" to detect the spread of a bacterial disease called brucellosis.

Somatic Cell Nuclear Transfer (SCNT) is a cloning method that involves transferring a nucleus from a somatic cell of the individual to be cloned to an enucleated egg.

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

In this activity (on pages 24-34), learners explore the four-part stomach of cows (and other grazing animals called ruminants), and compare it to the human one-part stomach and its digestive process.

In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

This is an activity which will allow learners to gain an understanding of lemur behavior through observation and role play.

In this online Flash game, learners will explore a coral reef using an underwater remotely operated vehicle (ROV).

In this activity, learners perform an experiment that replicates the dilemma faced by birds in acquiring food from a confined area.

This is an activity about the adaptations that allow the Aye-aye to survive in its habitat. Learners will explore how the Aye-aye collects food and how this is influenced by their specialized finger.

In this activity (25th on the page) about learning and memory, learners explore a training method that animal trainers employ called "shaping." Working in pairs, learners will attempt to "shape" each

In this environmental science activity about biodiversity, learners play a game to discover the effects of non-native species on an ecosystem.

In this activity, learners pretend that they are orcas and search for their "pods" using Morse code.

In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.

Professor John Endler traveled to Trinidad in the 1970s to study wild guppies. In this activity, learners take part in an online simulation of Endler's work.

In this simulation, learners model two elephant seal populations and how they change over time. Learners start with cards representing a variety of seals.

In this game of chance, learners will discover how organisms colonized the Galápagos Islands, experiencing how chance plays a role in the successful dispersal of species to new areas.

In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.

In this outdoor winter activity, learners search for and create hibernation sites that will protect gelatin "animals" from freezing.
