This is an activity about modeling the effect of wind on a sandy surface. Learners will use trays of sand and straws to recreate surface features of images of Mars. Participants test their ideas about how some of the features on Mars might have been... (View More) produced. This is activity 4 of 9 in Mars and Earth: Science Learning Activities for After School.

This is an activity about modeling and the scientific process. Learners will discuss the models they created in the previous three activities as models of forces that shape the surface of planets, and talk about the similarities and differences... (View More) between models and real events. Then they brainstorm a list of questions and suggest ways scientists might find answers. This is activity 7 of 9 in Mars and Earth: Science Learning Activities for After School. (View Less)
Learners will use trays of sand and cups of water to recreate surface features seen in images of Mars. This is activity 5 of 9 in Mars and Earth: Science Learning Activities for After School.
In this activity, students experiment to test the hypothesis that Mars was once hotter. The activity requires some advance preparation by the teacher: the day before the activity, need to place a plastic bottle filled with water in the freezer.... (View More) Materials needed include plastic bottle of water and thermometer. It is a companion piece to a CD about the exploration of Mars that uses song and drama to tell the story of Spirit and Opportunity, NASA's Mars Exploration Rovers, and their mission to search for signs of ancient water.

In this activity, students construct adding slide rules, scaled with linear calibrations like ordinary rulers. Students learn to move these scales relative to each other in ways that add and subtract distances, thus calculating sums and differences.... (View More) This is Activity A1 in the "Far Out Math" educator's guide. Lessons within the guide include activities in which students measure, compare quantities as orders of magnitude, use 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)
