This outdoor activity/field trip requires a place where minnows swim, such as a local pond or brook.

In this activity, learners rotate through several learning and play stations to explore dinosaurs and paleontologists.

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

In this outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves.

In this activity about dinosaurs, learners explore how and why fossils form. First, learners are introduced to dinosaur fossils by reading the book "Bones, Bones, Dinosaur Bones" by Byron Barton.

In this fun snack and craft activity, young learners make "Ants on a Log" and their own model of an insect. The purpose is to learn the three main insect body parts—head, thorax and abdomen.

In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.

In this outdoor, warm weather activity, learners use sweepnets to search a grassy area such as a large lawn or field, collecting small animals to find as many different kinds of animals as possible.

In this outdoor activity/field trip, learners conduct experiments to explore where dragonflies and damselflies perch or rest, and how the flies change behavior in reaction to other flies or fly decoys

In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin

In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

In this outdoor, mystery-solving activity, learners work like detectives, gathering evidence to identify the culprits that are attacking plants.

In this math lesson, learners apply the concepts of ratio and proportion to the capture-recapture statistical procedure.

In this outdoor activity and animal-role-play game, learners discover and uncover the hidden world of "cryptozoa"—organisms such as spiders, salamanders and slugs that live under objects, like rocks a

In this outdoor game, learners play the roles of gray or red squirrels gathering and storing a supply of food in "fall" and recovering enough of them to survive the "winter." Learners carry bags repre

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 outdoor activity and fun race, learners first find the most common type of tree in a forest site.

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
