The children use "a box of junk" to create different boats. One boat is made from straws, another from paper towel rolls, and the third from a pie pan. The children take their boats to a small pool to find out if they float. Some work and some do ...not. The children discuss why they did or didn't work.

Here's a quick lesson in buoyancy. It compares the weight of an object in the air compared to in the water. English captions are at the bottom of the screen. The words are small so the viewer may want to open the video to 'full screen'.

What will it take to make a floating toy sub sink to the bottom of a bathtub? You're sitting in a boat in a pool of water. With you in the boat is a large rock. You toss the rock overboard. Will the pool's water level rise, fall, or stay the same? ...Which way do you think a helium balloon inside an idling car will move when the driver puts the pedal to the metal? Put your understanding of the factors that influence an object's buoyancy to the test in this interactive brainteaser from the NOVA Web site.

This video describes buoyancy and explains why some things float in water while others sink. It also provides a quick review density (the amount of mass in a given volume) and how density and volume affect buoyancy. (5:55)

The talk show reporter Gerri Poveri is reporting that there is a monster in Walker Lake (apparently based on the Loch Ness Monster, as it is also plesiosaur-like). The class is very eager (especially Wanda) to find it. Phoebe also wants to find the m...onster so she can feed it. However, the bus' automatic sinking button is broken. They will have to find some other way to get it to sink. They succeed by adding weight and "crumpling" the bus. However, at the bottom, they discover that the monster was a fake; Gerri Poveri made the story up to increase her ratings. Now they will have to make the bus float again, so they can tell the truth to the public. (22:00)
