1. Introduce the children to the challenge! We know quite a bit about the Moon. Data from previous spacecraft missions and samples and information returned by the Apollo astronauts have helped scientists and engineers build an understanding of the Moon’s history and environment — and have led to more questions about how our Moon formed and evolved, what resources exist, and where we can find them. We face the exciting challenge of having humans return to the Moon by 2020 to live and work at a lunar outpost for a long period of time. This experience will help us prepare to investigate other planets like Mars and beyond.
Right now, several sites for a future outpost have been proposed by scientists and engineers. More information will be needed to make a final determination. In 2008 NASA is sending a spacecraft — the Lunar Reconnaissance Orbiter (LRO) — to orbit the Moon for a year and collect more detailed science information that will help them learn more about the Moon and better determine which site is the best site for an outpost. The LRO carries several instruments aboard, each designed to collect different information about the lunar environment, including temperature, topography (elevation), radiation, and resources such as the possibility of water ice in permanently shadowed regions.
For this activity, each team’s mission is to gather information about different lunar locations and determine the most promising site for a future human lunar outpost. Picking one site on the Moon is a balance between the resources available, really cool science, ability to move around the site, and safety considerations. As a group, the teams will debate the pros and cons of the sites they chose — just like their NASA counterparts! — and determine one site to recommend to NASA as the location for a future base.
2. Divide the children into teams of 3 to 4 and provide each team with a Mission Information Packet and colored dots or colored pencils or markers. Have them select a team name and review the information.
3. Invite the teams to begin their investigation. Each team begins by discussing their strategy – which location should they study first? Together the team goes to the site and reviews the data. They determine if the data support a possible human lunar outpost, do not support future human activity, or if more data are needed from future missions before they can decide. The teams mark their Matrix accordingly — one color of dot if the site is a “go;” another if it is a “no,” and a third for “more data needed.” The LRO Mission is going to collect more data to help scientists and engineers make these determinations!
When finished with a particular set of information at a particular a site, the team determines which site to visit next and they proceed to that location.
4. As the teams finish reviewing the site information, have them regroup. Allow a few minutes for individual teams to determine which site to recommend and to complete their information card. Remind them that site determination is not solely about resources or engineering challenges; the types of science questions that can be addressed are important parts of the discussion, too!
5. Invite each team to share their conclusions. On a whiteboard or poster paper, keep track of which sites are recommended by each team, and why.
Remind them that they need to make one recommendation as a whole group — and that their discussion is very similar to how NASA scientists and engineers debate where robots, orbiters, and humans should go!
If there are multiple sites recommended, invite the children to debate the attributes of each and determine which one ultimately should be recommended.
Looking for a bigger challenge? Invite the teams to find information about other sites for which they may want to propose a lunar base.
