The Scientific Method
Overview:
This podcast was created by a GEMS-U team using the lesson plan "Toilet Paper Strength".  The girls in the video demonstrate the scientific method by testing various brands of toilet paper.  They begin by discussing the steps in the scientific method.  Then, to review each step, the girls use the experiment described in the lesson plan using pennies, water, and samples of toilet paper.  Through this simple video, other students can see a simple version of the scientific method.

Dauphin Island Sea Lab Field Trip
Overview:
This podcast gives a brief overview of our field trip to the Dauphin Island Sea Lab.  This incredible weekend excursion provided 35 8th grade science club students a chance to explore a barrier island, view marine life hands-on, and study ecological and evironmental elements of the Gulf of Mexico.  The students participated in several activities such as trip to the local estuarium, a boat trip on the sea lab research vessel, a salt marsh trip, shark dissection, and a plankton study.  The students learned a tremendous amount about the Gulf of Mexico and Dauphin Island.  The trip was amazing and the students still talk about it today!

Einstein Demonstrations- Photo-Electric Effect in Action
Overview:
The understanding that light interacts with matter like a particle also lead to modern information technology, like computers, TVs, and lasers. The communicator is a direct example of the Photo-Electric Effect, one of Einstein’s groundbreaking 1905 theses. This is the achievement for which he won the Noble Prize for Physics in 1921. The Photo-Electric Effect centers on the ability of light to free up electrons inside metal atoms. This induces electric current through out an illuminated piece of metal. The idea that light can physically disturb electrons denotes a particle nature of light. The energy produced is proportional to the frequency of light, not the intensity of light. This fact draws on the wave-like properties of light within the same interaction.
