Rock Pioneers
Source Institutions
In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

Dark Adaptation
Source Institutions
In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.

Attention!
Source Institutions
In this outdoor art/environmental activity, learners create designs that will attract attention to animals and plants in particular habitats, and then test whether their designs attracted the "right"
Coincidental Colonization
Source Institutions
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.

Dr. Vet: Noses, Ears, Legs and Eyes
Source Institutions
In this activity, learners practice counting and multiplication as they figure out how many animal body parts they have to examine as "Dr. Vet."

The Scoop on Scallops
Source Institutions
In this data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.

Coral, Carbon Dioxide and Calcification
Source Institutions
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.

Crunch Time
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

Fish Features and Habitats

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

Ants
Source Institutions
In this outdoor activity, learners investigate ant behavior by testing ant feeding reactions to different types of food.

Discovery Time: Birds
Source Institutions
In this activity, young learners, (2 years and up) explore bird behavior and adaptations by providing a homemade bird feeder and observing birds.
