Calculate the time it would take to travel to Sirius. Relate the size of stellar travel times to the need of using EMR communication signals to send and receive a message. Mission 3 Calculating Stellar Distances. Project Haystack Mission 4 Project Haystack Calculating Stellar Travel Time. Students calculate the time for light to travel from various objects to Earth, given their distance to Earth.
Students describe two difficulties in obtaining information about the universe.
Use models including mathematical ones to explain phenomena or make predictions. Analyse a series of diagrams showing the spectra of a number of different stars. Use NASA website or articles from National Geographic to research the life cycles of stars. Use a Hertzsprung-Russell diagram to interpret information about stars eg illumination, surface temperature, colour, stage of life. The chemical elements in stars.
