Surfing the Net with Kids: Sink or Float
"Buoyancy (the force that keeps things afloat) is a concept for curious minds of all ages. From the youngest (Does it float or sink?) to the most sophisticated (Density is calculated by dividing mass by volume), I’ve found something for everyone."

Surfing the Net with Kids: Bubbles
"Looking for some good clean summertime fun? Try making a batch of bubble solution and a homemade bubble wand. My favorite recycled bubble wands are those green plastic strawberry baskets that accumulate in the kitchen ’cause I hate throwing them away. For more tips on bubble blowing than you ever imagined, and a look at the science behind those magical multi-colored floating spheres, here are this week’s site recommendations."

Soap Films Made Easy
"Imagine studying soap bubbles for a living! That’s what Maarten Rutgers does. For high school science students, and other serious science fans, this site goes far beyond what is covered in the other sites. Click on Fun/Bubble Details to learn that ""a bubble is a film, but a film is not a bubble. Bubbles usually start as a film, for instance in a bubble wand. Once you have blown on this film, it will separate to form a free floating entity called a bubble. Soap films must be bounded on all sides, or their surface tension will pull them into tiny droplets."""

Recount Feynman
"At first, the edgy design of this site interfered with my enjoyment of it. But once I conquered it, I was able to see beyond the design to the content. Here’s my advice: start with the red horizontal menu items at the top of the page, don’t overlook the scrolling vertical menu that appears on the left, and use the small white triangles to scroll through the text. You’ll be rewarded with a Feynman bio, photo gallery and book excerpts. Best clicks are the stories found under ""adventures."""

PBS: Buoyancy Basics
"When you place a block of wood in a pail of water, the block displaces some of the water, and the water level goes up. If you could weigh the water that the wood displaces, you would find that its weight equals the weight of the wood. After you’ve digested the basics of buoyancy, you’ll be ready for the three Buoyancy Brainteasers. This PBS site is my pick of the day because of its clear explanations, simple graphics, and challenging brainteasers!"
