Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

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 at the top of the page), learners make an easy river strainer and see what they can catch.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

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