Detectable Civilizations in Our Galaxy 5
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.
Galaxies Galore, Games and More
Students 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.
Detectable Civilizations in our Galaxy 1
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.
Detectable Civilizations in our Galaxy 2
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.
Galaxies by KIDS DISCOVER
An e-magazine with kid-friendly informational text, vibrant visuals, and activities about galaxies.
Detectable Civilizations in our Galaxy 4
Mr. Khan works through the equations that he derived in previous videos. In this fourth video of in a series of five, he uses an equation that he created himself.
Students use the provided website to classify galaxies after exploring information about elliptical, spiral, lenticular, and irregular galaxies and using the Hubble Tuning Fork.
The Structure of the Galaxy
Young scholars infer the galaxy shape. In this structure of the galaxy instructional activity students observe the distribution of objects in the sky and answer questions.
Dark Matter: How Does it Explain a Star's Speed?
Studying spiral galaxies can make your head spin! With this video, find out how astronomers calculate a galaxy's rotational speed, and how the prediction that the outermost stars slow down does not seem to be true. The mystery may be solved by the presence of mysterious dark matter. Perhaps by showing this, you can inspire your space scientists to be the one who finally proves its existence! Because of the brevity of the clip, you may want to simply embed it within your own presentation.
Galaxy Hunter - A Cosmic Photo Safari
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.
Galaxy Distances and Mixed Fractions
In this galaxies and fractions learning exercise, 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.
Galaxies to Scale
In this scales and galaxies worksheet, high schoolers 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.
Counting Galaxies with the Hubble Space Telescope
In this counting galaxies instructional activity, students 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.
A Glimpse of the Most Distant Galaxy
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.
A Study of Hydra Cluster Galaxies
Students analyze a designated galaxy with a partner or in a small group.
Exploring a Galaxy
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.
The Speed of Galaxy Q2125-431
In this speed of a galaxy worksheet, students 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.
The Tomatillo Galaxy Adventure
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.
