Fragile Waters
Source Institutions
In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.
Water Body Salinities II
Source Institutions
In this activity, learners discuss the different salinities of oceans, rivers and estuaries.
Sandy Samples
Source Institutions
In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.
Habitat Adaptation Matchup
Source Institutions
In this activity, learners work in small groups to match various marine animals with their different environments.
Bouncy Egg
Source Institutions
In this activity, learners explore how acids can dissolve eggshells leaving behind a membrane-covered bouncy egg.
Catch & Release II: It's Catching On!
Source Institutions
Throw that fish back? A new generation of ethical anglers concerned about conserving resources is participating in "catch and release" fishing. How is this going?
Exploring the Ocean with Robots
Source Institutions
In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.
Corals and Chemistry
Source Institutions
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
The Great Plankton Race
Source Institutions
In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.
Crayfish Investigations
Source Institutions
This activity has learners interacting with live crayfish, but could be adapted for a variety of similar hardy and interesting organisms.
Fish Wheels
Source Institutions
In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur
Exploration Tank
Source Institutions
This is a guide for facilitating interaction at a touch tank with marine animals. The instructions are for setting up a display in an informal science center, but could work anywhere.
What is in the Water?
Source Institutions
In this activity, learners use open inquiry to learn about the process of science as well as gain experience regarding the Law of Conservation of Mass, dissolution, and density.
Conductivity: Salty Water
Source Institutions
Water, whether fresh or salty, serves as one of the best electrical conductors on the planet. Does salt effect its conductivity?
Portable Potable Pressure
Source Institutions
In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.
What-a-cycle
Source Institutions
In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.
