Subject: Science
Title: Harnessing Solar Energy
Description: The purpose of this Science NetLinks lesson is to discover the properties of light (radiant) energy from the sun by experimenting with solar collectors, cookers, and calculators. This investigation could be the beginning of a unit on the many forms of energy.

Subject: Science
Title: Exploring Pendulums
Description: In this Science NetLinks lesson, students explore Web sites with simulations of pendulums, where they are able to change the length and angle of the bob and observe its effects. They then construct and test their own controlled-falling systems, or pendulums, to further observe and verify these theories. This lesson helps students understand concepts related to how gravitational forces act on objects by exploring the motion of pendulums.

Title: Making Light of Science
Description: The purpose of this Science NetLinks lesson, the first in a three-part series on light, is to introduce students to the electromagnetic spectrum, focusing on visible light. Students are introduced to the idea that all light travels as waves, and that wavelength defines the various regions of the electromagnetic spectrum.

Title: The Lighter Side of Color
Description: This Science NetLinks lesson, the second of a three-part series on light, focuses on the idea that we can see objects because they either emit or reflect light. It discusses the way light is reflected, absorbed, and scattered to allow certain wavelengths to reach the eye, leading to a perception of different colors. It is an introductory exploration and would be best if complemented with hands-on activities.

Title: Looking into Space
Description: In this Science NetLinks lesson, students learn how telescopes work, build a model of their own, and consider how real telescopes can be used to ask--and help answer--questions about the universe. This activity is based on instructions and information from the Exploratorium Web site.

Title: Cell Phone Traffic
Description: In this Science Update, from Science NetLinks, you'll hear about a new use for cell phone signals. Many people stuck in traffic pass the time or take care of business by making calls on their cell phone. Now, scientists have found another way to put that talk time to work by using cell phone signals to monitor traffic flow. Science Updates are audio interviews with scientists and are accompanied by a set of questions as well as links to related Science NetLinks lessons and other related resources.

Title: Dryer Sheets
Description: In this Science Update, from Science NetLinks, you'll hear how the old saying opposites attract relates to your laundry. Positively charged particles are attracted to negatively charged particles, which can cause static cling in clothing. Science Updates are audio interviews with scientists and are accompanied by a set of questions as well as links to related Science NetLinks lessons and other related resources.

Title: Snow Goggles
Description: The aim of this lesson, from Science NetLinks, is to illustrate how the scientific method can be used to solve different kinds of problems. As part of this lesson, students build snow goggles similar to those used by the Inuit peoples. Students also create their own version of the goggles to improve upon existing designs and compare the process used to invent snow goggles with that employed by designers of the MESSENGER spacecraft.

Title: Finding Monster Waves
Description: In this lesson, from Xpeditions, students learn about the varying sizes of ocean waves, what causes the variation, and where to find giant waves. Students learn the parts of a wave and discuss wave height, wavelength, and wave period. They experiment with creating waves on the National Geographic Wave Simulator and discuss how geography affects waves.

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- Light Defraction
Overview:
This demonstration exhibits light’s wave-like characteristics. This is half of light’s duality; the other half being light’s particle-like characteristics. Using diffraction gratings we can compare the visible parts of atomic spectra for different elements. A diffraction grating consists of a large number of equally spaced parallel slits. These slits bend light differently according to wavelength. Incandescent lights work by heating a solid piece of tungsten wire. This heating of a solid produces a variety of wavelengths, giving an impressive spread of colors when viewed with a diffraction grating. Since the other lamps are single gaseous elements, they emit only a few wavelengths of light, their individual atomic spectra.

Einstein Demonstrations- Speed of Light
Overview:
Einstein's crucial breakthrough about the nature of light, made in 1905, can be summed up in a deceptively simple statement: The speed of light is constant. So what does this sentence really mean? Surprisingly, the answer has nothing to do with the actual speed of light, which is 186,000 miles per second through the "vacuum" of empty space. Instead, Einstein had an unexpected insight: that light from a moving source has the same velocity as light from a stationary source. For example, beams of light from a lighthouse, from a speeding car's headlights and from the lights on a supersonic jet all travel at a constant rate as measured by all observers—despite differences in how fast the sources of these beams move.

Einstein Demonstrations- Color Mixing
Overview:
Mixing color light is called additive color mixing, because the combined colors are formed by the adding of light from two or more light sources together. Two or more lights added together will give more illumination than any of the lights by themselves. The primary colors of light are red, green and blue.
