The lecturer discusses reasons why we haven't detected any of the possible 12.5 civilizations that are deduced to be residing in the Milky Way Galaxy based on the Drake equation. The space between possible civilizations is discussed, as well is the massive interference that would make radio signals from other civilized planets hard to detect.
Young scholars practice skills used in scientific investigation while studying the three main types of galaxies. Students identify Earth as part of Milky Way galaxy, the parts of galaxies, and the types of galaxies, as well as classify galaxies by size and shape in a computer game.
Tenth graders explore the structure and content of galaxies. Through discussion, lab, and hands-on activities, they discover the general structure of the three types of galaxies as well as the effect they have on the structure and function of the universe. Two lessons are included.
Young scholars use the provided website to classify galaxies after exploring information about elliptical, spiral, lenticular, and irregular galaxies and using the Hubble Tuning Fork.
Students infer the galaxy shape.  In this structure of the galaxy lesson students observe the distribution of objects in the sky and answer questions.
Sal narrates the last video concentrating on the scale between stars and galaxies themselves.
Space science stars journey through our night sky and take virtual photos of galaxies to investigate simple random samples. Higher math is used to analyze the data collected. Copy the evaluation/assessment questions onto a handout for learners to answer as they work though the interactive component. 
In this galaxies and fractions worksheet, students solve 8 problems involving the distances of galaxies from each other by using mixed fractions to solve each problem. They use the megaparsec as the unit of measurement.
In this scales and galaxies worksheet, learners solve 7 problems including finding the size of galaxies in comparison to other galaxies and drawing scale models of the given galaxies to show their relative sizes and shapes.
In this counting galaxies worksheet, learners use a photograph taken by the Hubble Space Telescope and they divide the field into 16 square areas. They find the average number of galaxies in the cells, they find the area of one of the cells and they determine the total number of galaxies the Hubble Space Telescope detected in the photograph.
In this most distant galaxy worksheet, students use a Deep Field image taken by the FORS camera at the ESA-VLT observatory to answer 4 questions about the redshifts identified in the field. They use an on line redshift calculator to determine look-back times for each galaxy.
Students research the constellations and discuss their findings. Then they construct their own maps of the galaxy using paper, black paint, aluminum foil, etc. They make a 3-D map of their chosen constellation.
Students analyze a designated galaxy with a partner or in a small group.
In this galaxy worksheet, students use the Internet or other resources to answer 13 questions about the galaxy NGC-1232. They are given a photograph of the galaxy to help determine the width and diameter of certain regions of the galaxy.
In this speed of a galaxy worksheet, learners use a given equation for the speed of an object and they use the spectral lines for Hydrogen Alpha and Beta from the Seyfert galaxy to answer 6 questions. They determine the observed wavelengths, the rest wavelengths, the velocities of the wavelengths and if the galaxy is moving towards or away from the Milky Way Galaxy.
Students explore the site Second Life and discover the Tomatillo Galaxy. In this Tomatillo Galaxy lesson plan, students make a diorama and give an oral presentation about the Tomatillo Galaxy.
In this orbit of stars in galaxies worksheet, students are given an equation that models the orbital speeds of stars as they relate to their distance from the nucleus of a galaxy. Students solve 5 problems using this equation and determine how fast stars orbit a galaxy, the maximum velocity of a star and the years it takes a star to complete an orbit.
For this Sombrero Galaxy worksheet, students observe infrared images taken by the Spitzer Infrared Telescope and the Hubble Space Telescope. They answer 9 questions about the details of the images such as the radius of the stellar component, the thickness of the dust disk and the diameter of the bright nuclear core.
Sal runs through a framework for detecting possible civilizations in our universe. He deals with the number of stars and uses the requirements for civilizations to derive how many potentially suitable planets there might be. The Drake equation can help us figure out approximately how many suitable planets there are.
The idea of whether or not communication from other planets can be transmitted and received is discussed in this presentation. The various issues such as relative stages of development, the ability to receive a transmission, and whether any possible signal has been sent in our direction are discussed.
