Students research particular types of lasers and find examples of how they are used in technology today. Teams present their findings by means of PowerPoint presentations, videos or brochures. The class takes notes on the presentations using a provided handout. This activity prepares students for the "go public" phase of the legacy cycle in which they solve the grand challenge by designing and producing a laser-based security system.
Subject:
Mathematics and Statistics, Science and Technology
In this activity students learn that elements are the basic building blocks of all things found on Earth and in space including water, the human body, and the Earth, the Sun, and the planets. By counting elements extracted from sample of beads designed to simulate a Genesis sampling grid, they will learn how the extraction of atoms from the Genesis samples help scientists have a better understanding of the abundances of elements in the solar wind. The hands-on experience helps students to discover that the elemental abundances from the sun can be used as a baseline to compare with the diverse bodies of our solar system. A student worksheet and data spreadsheet are provided.
