In part 1 of this video, the Bears go on a mountain family vacation. However their plans don't turn out just right-everything from a flat tire to a run down cabin full of wild animals and no electricity. The bears find out that "A bear's vacation more rain than sun ends up being the one that's more fun". This is a good companion teaching resource for reading Berenstain Bear books in the classroom and/or library and helps to bring literary characters to life. This is part 1 of 2. (5:46)

All physical phenomena of nature are explained by four forces. Two nuclear forces -- strong and weak -- dwell within the atomic nucleus. The fundamental force of gravity granges across the universe at large. So does electricity, the fourth fundamental force, which binds the atoms of all matter.

There are about 20 videos of science experiments on this page. This video shows how regular fluorescent lightbulbs can glow when brought close to a plasma ball found in many novelty shops. The bulbs glow because the electricity in the plasma globe is sent from the center of the ball at high frequencies, similar to radio waves. The gas inside of fluorescent bulbs react the the high frequency electricity and they begin to glow! All the videos are done interview style and so some background research is needed before they are shown.

In this short video, students will learn about the vocabulary word "insulator". Insulator is defined as 1. something that isolates or protects something else and 2. something that prevents electricity, heat or sound from escaping. Good examples are given (coat, coffee mug, feathers, fur, wall insulation, and wire). This is a good resource to help upper elementary and middle school students understand this concept. (01:01)

In this interactive activity adapted from NOVA Online, learn how a typical photovoltaic cell converts solar energy into electricity. Explore the components of a photovoltaic cell, including the silicon layers, metal backing, antireflective coating, and metal conductor strips. Using animations, investigate why the silicon layers are doped with phosphorous and boron, and how an electric field is used to generate electricity from sunlight.
