Why is the ocean salty?

How do whales stay warm?

What causes tides to rise and fall?

How do oil spills affect ocean animals?

Now you can discover the answers to these and many other fascinating questions about the ocean--the earth's last frontier. Janice VanCleave's Oceans for Every Kid makes learning about the ocean and its inhabitants an intriguing adventure. Use a bottle, pennies, a straw, and clay to demonstrate how submarines rise. Make your own wave holder with index cards and a plastic folder. Through these and other activities you'll find out how fish move up and down in water, how pollutants move into the ocean, how to navigate without a compass, how to map the surface of the ocean floor, and much more.

Each of the activities begins with a statement of purpose followed by a list of materials, step-by-step instructions, expected results, and an easy- to-understand explanation. Every activity has been pretested and can be performed safely and inexpensively at home or in the classroom.
