This Michigan State University/Lansing Boys and Girls Club partnership demonstrates the powerful result of giving youth the science background and tools they need to carry out investigations of their own design, and to communicate their knowledge in their own voice.

Traveling Through Time

Is it possible to travel through time? Einstein’s theory of relativity states that the stronger the gravitational pull on an object, the more time slows for that object. Scientists predict that if someone were to travel to a place with a lot of gravity, like near a black hole, time would pass more slowly for that person. In this video excerpt from NOVA’s "The Fabric of the Cosmos: The Illusion of Time," host and theoretical physicist Brian Greene takes a journey through space—and time—to illustrate what time travel might really be like.

The construction of a drum -- the materials it is made of, its size and shape, and the tension of its top, or drumhead -- all affect how the drum sounds. In this video segment, two members of the ZOOM cast create drums of different sizes, shapes, materials, and tensions, and compare the results.

This video is available in both English and Spanish audio, along with corresponding closed captions.

As humans, we thankfully have more going for us than the balloon brains depicted in this video segment adapted from ZOOM. Still, the failed efforts of some of the ZOOM cast members to design adequate protection for their balloon brains illustrates the importance of wearing a proper helmet and protecting your own brain whenever you skate, rollerblade, ski, or ride a bike.

Once it's been read, there's often little more to do with the daily newspaper than to add it to that towering stack of recyclables we collect each week. In this video segment, however, the ZOOM cast demonstrates how innovative design can turn this otherwise flimsy material into a relatively solid piece of furniture.

Explore water drops using this video excerpt from Curious George: The Color of Monkey. In the video, George promises the Man with the Yellow Hat that he will stay clean until their picture is taken for the cover of Bird Watchers Magazine. When George encounters pots of colored water, however, it becomes difficult to keep his promise. In the accompanying lesson plan, children move water drops using various tools to explore how the water drops change when they move.
