This activity demonstrates optical properties of water: that different constituents in water affect the transmission, absorption, and scattering of different colors in the visible light spectrum. Inexpensive, off-the-shelf components are used to... (View More) build a light sensor and source, creating a simple spectrophotometer that can measure light absorption. In the second part of this activity, principles of ocean color remote sensing are applied to measure reflectance. Using components that are clearly visible allows students to configure them in different ways. Playing with the instrument design gives students a practical understanding of spectrophotometers, in-water optics, and remote sensing. As an extension of this concept, students are encouraged to think about how ocean color is used to estimate the concentration of chlorophyll to infer phytoplankton abundance, colored dissolved organic matter, and suspended sediments.

This science news story highlights a new initiative by the Hubble Space Telescope to image distant galaxies. The program uses gravitational lenses to image galaxies that are otherwise too distant and faint for the telescope to image. The story... (View More) includes information describing how gravitational lenses are similar to optical lenses. The article also includes a description of parallel fields - a set of observations done in tandem with the gravitational lens observations that will result in six additional HUDF-type observations of the sky. Star Witness News is a series of articles, written for students, that are inspired by Hubble Space Telescope press releases. Supplemental education materials include vocabulary, discussion questions and answers, and identifies relevant Common Core State Standards for English Language Arts. (View Less)
