In this activity, students produce a land cover map of a 15 km x 15 km GLOBE study site from hard copies of Landsat satellite images. Students place clear transparencies over the Landsat TM images and use markers to outline and classify areas of... (View More) different land cover using the MUC System. Students use their local expertise of their GLOBE study site and their sample site measurements to create and assess the accuracy of their maps. The resource includes a sample Landsat image, an example of an accuracy assessment work sheet, and a difference-error matrix to validate the degree of accuracy of the student product. This resource is a procedural tutorial supporting the protocol within the Land Cover/Biology chapter of the GLOBE Teacher's Guide. (View Less)

This is a lesson about Saturn. Learners will listen to a read-aloud of the history of Saturn discoveries. Next, they learn two reading comprehension strategies (visualizing and wondering) that they can use to become more powerful readers of... (View More) nonfiction text. Finally, students share their work with partners and the class. This is lesson 3 of 12 in the Mission to Saturn Educators Guide, Reading Writing Rings, for grades 3-4. (View Less)

This is a lesson about distances in space. Learners will create an outdoor, to-scale model of the distances between the Sun, Earth, and Saturn. Next you will conduct a guided walk to Saturn - which gives students an understanding of how far away... (View More) Saturn is from Earth and the Sun. Like enthusiastic travelers everywhere, students will write a “postcard home” to share their exciting trip. This is lesson 4 of 10 in "Reading, Writing & Rings!" for grades 1-2. (View Less)

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) uses Gamma-ray Bursts as an engagement tool to teach selected topics in physical science and mathematics. In addition, the guide features background information, assessment information, student worksheets, extension and transfer activities, and detailed information about the physical science and mathematics content standards for grades 9-12. This is Activity 4 of 4 in the guide which accompanies the educational wall sheet, titled Angling for Gamma-ray Bursts. (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 uses Gamma-ray Bursts as an engagement tool to teach... (View More) selected topics in physical science and mathematics. In addition to the activities, it features background information, assessment information, student worksheets, extension and transfer activities, and detailed information about the physical science and mathematics content standards for grades 9-12. This is Activity 3 of 4 in the guide which accompanies the educational wall sheet titled Angling for Gamma-ray Bursts (View Less)

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.

In this activity students use log tapes and base-two slide rules as references to graph exponential functions and log functions in base-10 and base-2. Students discover that exponential and log functions are inverse, reflecting across the y = x axis... (View More) as mirror images. This is activity E2 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, the GLAST mission was renamed Fermi, for the physicist Enrico Fermi. (View Less)

In this activity students construct Log Rulers, finely calibrated in base-10 exponents and numbers (logs and antilogs). They practice reading these scales as accurately as possible, listing all certain figures plus one uncertain figure. This is... (View More) activity D1 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.

This kinesthetic activity simulates the process of evolution by natural selection. Students take on the roles of crab-like predators that exhibit one of four variants of feeding appendage: a spoon, fork, knife, and chopsticks. The simulation runs... (View More) for three trials, as the predators use their appendages to harvest pinto beans, with varying success. Students track the frequency of each appendage type through three generations. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

In this activity, students graph second and third order functions, discovering an inverse relationship between squares and square roots and between cubes and cube roots. Students graph these functions on both linear grid (evenly spaced numbers), and... (View More) a log-log grid (evenly space exponents). Graph lines that curve on linear grids transform into straight lines on the log-log grids, with slopes equal to their exponential powers. This activity is activity E3 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.
