In this activity, students build a model of an active galaxy. From this, they will learn about the geometry of the components of an active galaxy and develop an understanding that different viewing angles can lead to dramatically different interpretations of a galaxy's appearance. The activity includes background information, glossary, essential questions, extension activities, transfer activities, ... Full description.

This activity focuses on the question, What do active galaxies look like when viewed from different distances? Students work in small groups to learn about the small angle formula, construct a template, and use it to correctly measure the angular size of a person. Students then use the Active Galaxies Poster to measure the angular size of a galaxy. Materials are commonly available or inexpensive items, ... Full description.

In this activity, learners will explore the question, What is the chance that we are the only life in the universe? They determine what we need to know to predict the chances of extraterrestrial life. They then make estimates of the number of worlds in the Milky Way galaxy that have life using the Drake equation. This is activity 5 of 5 in "Astrobiology in your Classroom: Life on Earth..and Elsewhere?" ... Full description.

This is a lesson about the requirements for life on another planet. Learners will grow organisms in one of 12 classroom environments and identify common requirements (such as water, nutrients, and energy). They will also design a mission to identify habitable places by searching for water, nutrients, and energy. A math extension explores measuring calories. This is activity 2 of 5 in "Astrobiology ...

This activity uses Dr. Drake's framework to have students consider the implications of each term and make their own estimates of life in the Milky Way galaxy. This activity is part of a guide that was developed in conjunction with the Cosmic Questions exhibit and complements a museum visit. However, the activities can also be used independently. The format is flexible, and educators can pick and choose ... Full description.

This lesson uses a simple discrepant event to demonstrate the underlying cause for early miscalculation of the size of the Milky Way galaxy. By standardizing the Cepheid period-luminosity relationship without recognizing there were two types of Cepheid variable stars with intrinsic differences in absolute magnitude, a distance calculation error occurred. Requires two lamps and two soft-white light ... Full description.

This is an activity about spacecraft radio communications. Learners will explore spacecraft radio communications concepts, including the speed of light and the time-delay for signals sent to and from spacecraft. Learners measure the time it takes for a radio signal to travel to a spacecraft using the speed of light, demonstrate the delay in radio communication signals to and from a spacecraft, and ...

This problem set is about scale. Using a ruler, learners will measure the distance between two points on a satellite image and determine the scale of the image and other information to answer a series of questions. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to Earth Science and Climate Change. Full description.
