a Tree in the Sun: Visualizing Photosynthesis

Photosynthesis video showing how plants use sunlight to create energy. Great video that starts at the macro level and zooms in to show the breaking and forming of bonds at the molecular level.

Fantastic science trick! You need milk, dish soap, food dye, a plate. Spectacular & colorful demonstration of how soap breaks surface tension. A great classroom demonstration, or entertainment for kid parties. For detailed information on this experiment, please visit the amazing Steve Spangler web site, at

One of the many sites now creating real world Math lesson plans. This site is the best I've come across, and each lesson comes with an accompanying student handout and sliderocket presentation complete with video and associated student notes.
