This is a lesson about Saturn. Learners will create a multilayered book with diagrams of Saturn showing its various layers, ring system, and many moons. To enhance background information on Saturn, students will practice listening to informational... (View More) text. Students will also create their own texts to support and explain their Saturn diagrams. This is lesson 9 of 10 in "Reading, Writing & Rings," for grades 1-2. (View Less)

This lesson is comprised of four parts grouped to enable student appreciation of the importance of making accurate scientific observations, descriptions, and drawings. In part one (The Truth is Out There), students describe an object given to them... (View More) by their instructor. In part two (Who Knows?), students attempt to draw and identify a creature based on another student’s description. In part three (Tell It Like It Is!), students make new descriptions, using accurate observations and measurements of what they see. In part four (Truth Revealed), students assess the completeness of the more detailed descriptions. These activities are part of an astrobiology guide called the "Fingerprints of Life" which contains background information for students, worksheets, extension activities, suggested assessments, and alignment to standards.

In these activities, students investigate how gamma ray bursts emit energy in beams (as opposed to emitting light in all directions) and investigate the implications of this on the total number of gamma ray bursts seen in the universe. This activity... (View More) is part of a unit designed to use gamma-ray bursts - unimaginably huge explosions that signal the births of black holes - as an engagement tool to teach selected topics in physical science and mathematics. The guide is based on the 5E instructional sequence and features background information, assessments, student worksheets, extension and transfer activities. (View Less)

In this activity, students determine the direction to a gamma ray burst using the times it is detected by three different spacecraft located somewhere in the solar system. We assume that all the spacecraft are in the plane of the Earth's orbit... (View More) around the Sun; that is, there is no third dimension and that we are only concerned with two dimensions, x and y. We also assume the burst is billions of light years away, so the incoming gamma rays are traveling along parallel lines. This activity is part of a unit that is designed to use gamma-ray bursts - unimaginably huge explosions that signal the births of black holes - as an engagement tool to teach selected topics in physical science and mathematics. The guide is based on the 5E instructional sequence and features background information, assessments, student worksheets, extension and transfer activities. (View Less)

In this activity, students look at the distribution of aluminum foil balls arranged in a circle on the floor, and compare them to the distribution of gamma-ray bursts on the sky. This activity is part of a unit designed to use gamma-ray bursts -...

In this hands-on activity, students analyze the data on Mystery Object Cards, observe that astronomical objects have many observable properties, and discover that these properties allow scientists to categorize astronomical objects into different... (View More) groupings. Students also discover that, because objects can be grouped in different ways, discrete categorization is not always possible. This is why scientists need time to fully study and understand celestial objects and phenomenon. This activity is part of a unit designed to use gamma-ray bursts - unimaginably huge explosions that signal the births of black holes - as an engagement tool to teach selected topics in physical science and mathematics. The guide is based on the 5E instructional sequence and features background information, assessments, student worksheets, extension and transfer activities. (View Less)

This activity provides tips and ideas for helping children do science with a digital camera–and have fun while doing so. For example, cameras can preserve the presence of transient events like clouds, contrails, rain, snow, air pollution and... (View More) sunsets. Cameras can also document all kinds of living plants and insects, birds, reptiles and other animals. Photographs of specific scenes can be saved for months or years so they can be compared with new photographs to see if any changes have occurred. (View Less)

In this activity, students solve exponential equations where the unknown is contained in the exponent. Students learn that taking base-10 or base-2 logs pulls down the exponent, allowing the unknown to be isolated and solved. This activity is... (View More) activity C3 in the "Far Out Math" educator's guide. Lessons in the guide include activities in which students measure, compare quantities as orders of magnitude, become familiar with scientific notation, and develop an understanding of exponents and logarithms using examples from NASA's GLAST mission. These are skills needed to understand the very large and very small quantities characteristic of astronomical observations. Note: In 2008, GLAST was renamed Fermi, for the physicist Enrico Fermi.

In this activity students convert antilogs to logs, and logs to antilogs using scientific notation as an intermediate step. They will thereby develop a look-up table for solving math problems by using logarithms. This is activity D2 in the "Far Out... (View More) Math" educator's guide. Lessons in the guide include activities in which students measure,compare quantities as orders of magnitude, become familiar with scientific notation, and develop an understanding of exponents and logarithms using examples from NASA's GLAST mission. These are skills needed to understand the very large and very small quantities characteristic of astronomical observations. Note: In 2008, GLAST was renamed Fermi, for the physicist Enrico Fermi.

In this activity, students construct base-two slide rules that add and subtract base-2 exponents (log distances), in order to multiply and divide corresponding powers of two. Students use these slide rules to generate both log and antilog equations,... (View More) learning to translate one in terms of the other. This is activity C1 in the "Far Out Math" educator's guide. Lessons in the guide include activities in which students measure,compare quantities as orders of magnitude, become familiar with scientific notation, and develop an understanding of exponents and logarithms using examples from NASA's GLAST mission. These are skills needed to understand the very large and very small quantities characteristic of astronomical observations. Note: In 2008, GLAST was renamed Fermi, for the physicist Enrico Fermi.
