We have developed and classroom-tested instructional activities intended for the high-school level. Input from teachers has also been incorporated through the annual summertime JHU Quarknet workshops. The activities come with directions for the instructor and a workbook for students. To accommodate different circumstances and approaches, the activities provide instructor guidelines for multiple levels of independence by which the class can engage the material.
In the Cosmic Expansion activity, students use the electromagnetic line emission spectra of galaxies to estimate the rate at which the universe is expanding.
