This is an activity about coronal mass ejections. Learners will calculate the velocity and acceleration of a coronal mass ejection, or CME, based on its position in a series of images from the Large-Angle Spectrometric Coronograph (LASCO) instrument on NASA's Solar and Heliospheric Observatory (SOHO) spacecraft. This is Activity 2 of a larger resource, Exploring the Sun. The NASA spacecraft missions represented by this material include SOHO, TRACE, STEREO, Hinode, and SDO.

How big and how old is the universe? This culminating telescope investigation for high school students has them first taking images of galaxies near and far; then measuring and calculating their distances; then predicting how they might expect galaxies to be moving based on various models of gravity; and then comparing their results with the galaxy velocity measurements in a NASA database. From this data, students explore the concept of an expanding universe and can actually determine an estimate for the age of our universe. This activity is part of a DVD that is a professional development resource for educators. Many new astronomy learners, students and adults alike, are unfamiliar with the universe beyond the solar system. Instructions for obtaining the DVD and registering for the professional development workshop are contained on the website.

In this activity, learners work in teams to assess environmental conditions, resources, and scientific relevance of different locations on the Moon using data collected from previous lunar missions. Each team selects the site they believe has the best potential for a future lunar outpost. The teams debate their conclusions and work together to determine which single site to recommend to NASA. This activity takes approximately 1.5 hours, and can be divided into parts. Learners should be familiar with NASA's LRO Mission and the lunar environment through other Explore! To the Moon and Beyond! activities. These activities were developed specifically for use in libraries.

In this activity, student teams design small-scale physical models of hot and cold planets, (Venus and Mars), and learn that small scale models allow researchers to determine how much larger systems function. There is both a team challenge and competition built into this activity. Experimental findings are then used to support a discussion of human outposts on Mars. The resource includes an experimental design guide for students as well as a handout outlining a method for the design of controlled experiments, and student data sheets. Student questions and an essay assignment are provided as classroom assessments. This is Activity A in the second module, titled "Modeling hot and cold planets," of the resource, "Earth Climate Course: What Determines a Planet's Climate?" The course aims to help students to develop an understanding of our environment as a system of human and natural processes that result in changes that occur over various space and time scales.

In this activity, students pose several hypotheses for what will happen if you continue heating or supplying energy to the hot and cold planet models (Mercury, Mars, Venus, and Earth) and then test their hypotheses using a spreadsheet based radiation balance model. The activity supports investigation of a real world challenge, experimenting with life support conditions for Mars at an Arctic outpost. The interactive model runs are conducted using a Java applet. This resource includes student worksheets, assessment questions and a teacher's guide. This is Activity B in module 2, Modeling hot and cold planets, of the resource, Earth Climate Course: What Determines a Planet's Climate? The course aims to help students to develop an understanding of our environment as a system of human and natural processes that result in changes that occur over various space and time scales.

In this activity, students explore the importance of adequate sampling strategies when conducting a scientific investigation. They are tasked with determining the average temperature of the Earth, using data sets easily found on the Internet, and determine the kind and size of sample necessary to calculate a representative average. The resource includes a student data sheet and an authentic assessment for the module, where students discuss the establishment of a habitation site on Mars. This is Activity C in module 2, titled "Modeling Hot and Cold Planets," of the resource, Earth Climate Course: What Determines a Planet's Climate? The course aims to help students to develop an understanding of our environment as a system of human and natural processes that result in changes that occur over various space and time scales.

The purpose of this kinesthetic activity is for students to learn the relative motions of the Earth, Sun and Moon. Awareness of these different motions is needed to develop an understanding of the causes of the day/night cycle, the seasons and the cycle of lunar phases. 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.

This is an activity about the lunar cycle and the pattern of the moon’s motion in our sky. Learners will use the Sky Tonight online program to observe the different phases of a lunar month and predict where the moon will be in the night sky throughout the month. This activity requires the use of a computer with Internet access, and is Sky Tonight Activity 4 in a larger resource, Space Update.

In this activity, students compute the strengths of the gravitational forces exerted on the Moon by the Sun and by the Earth, and demonstrate the actual shape of the Moon's orbit around the Sun. The lesson begins with students' assumptions about the motions of the Moon about the Earth and the Earth about the Sun, and then test their understanding using an experimental apparatus made from a cardboard or plywood disk and rope. 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.

This is an activity about the phases of the moon. Learners will view and identify images of the different phases and measure the moon's size in each. This activity is Astronomy Activity 5 in a larger resource, Space Update.

Learners will work in teams to apply their knowledge about the Moon, its environment, and the LRO mission to match responses to Moon questions. With the correct responses, they build a picture of the Moon. This activity is part of Explore! To the Moon and Beyond! - a resource developed specifically for use in libraries.

This is a lesson about NASA's Lunar Reconnaissance Orbiter (LRO). Learners will sing about the LRO mission to the Moon, learn that craters on the Moon may harbor water ice, and they discover how LRO is searching for this and other resources needed to build future lunar outposts. This is a good introductory activity. This activity is part of Explore! To the Moon and Beyond! - a resource developed specifically for use in libraries.
