Title: Light Is
Description: The students will explore the properties of light in order to understand optics. Students will do two activities that will aid with their mastery of this concept.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.

Title: Magnify It!
Description: In this Science NetLinks lesson, students view objects of various sizes from several viewing distances to discover that their visual field is limited. Students record what they see and compare their observations with classmates in an open, nonjudgmental forum. They have the opportunity to speculate about and experiment freely with magnifying glasses and also conduct more structured experiments.

Title: Collecting the Rays
Description: In this lesson, from Illuminations, students explore how variations in solar collectors affect the energy absorbed. They make rectangular prisms that have the same volume but different linear dimensions. Students investigate relationships among the linear dimensions, the area, and the volume of rectangular prisms.

Title: Sink It
Description: This Science NetLinks lesson is designed to develop students' understanding of sinking and floating. Students first classify a group of common objects by a characteristic of their own choosing. Then they reclassify the same group of objects by their predictions about whether each item will float or sink in water. As a group, they design an experiment to test their predictions (hypotheses).

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.
