NASA/NSTA Symposium:

Symposium participants use different methods to measure the round tables in the room

The NASA/NSTA Symposium: Lunar Exploration took place at the Hilton Omaha Hotel in Omaha, NE, on Friday, October 20, 2006. Eight educators were in attendance, including three NASA Explorer School teachers. Five presenters worked with the group: Dr. Susan Hoban and Dr. Anuradha Koratkar, from the University of Maryland Baltimore County's Goddard Earth Science and Technology Center, Laurie Cook, from the University of Maryland Baltimore County, and college students Albert Hill, and Brendan Shaughnessy, from Wesleyan University and the University of New Mexico State, respectively. Their presentations focused on impact craters, taking measurements, compounded error, determining the size of craters on the Moon, history of lunar exploration, the use of robots for exploration, and robotic control. NSTA would like to thank all the participants and presenters for a job well done.


After an introductory administrative session during which Flavio Mendez, Symposia and Web Seminars Program Manager at NSTA, familiarized participants with the contents of their folders (including the agenda, talent release form, and pre-assessment), participants were invited to make their own impact craters using candy balls as impactors over plates containing flour and chocolate powder. Teachers enjoyed making their own craters and tried different things, like throwing the impactors at different angles and speeds to observe contrasting results. Dr. Hoban and Dr. Koratkar guided this exercise offering ideas for the classroom and pointing at the different parts of a crater. Immediately after this activity, the educators were asked to device a plan to measure the round tables where they were sitting in the symposium room. Different methods were used for measuring. Some teachers used their hands, others used their fingers, and a few measured half the table and used different mathematical formulas to obtain a result. Each participant's result was tabulated and analyzed. Dr. Hoban proceeded to lead a discussion about compound error and the inexact science of measurement. After this exercise, teachers were given a few handouts with photos of lunar craters and were tasked with finding the diameter of these craters to determine if a 9-meter size spacecraft could land safely inside them. The teachers used their acquired knowledge from the previous exercise, rulers, and calculators to answer the question.

Dr. Koratkar followed this activity with a presentation about exploration. She talked about the different reasons humans explore - for financial reasons, to conquer other territories, to search for religious freedom, and for knowledge. The latter is one of the reasons humans are again interested in exploring the Moon. The return of astronauts to the Moon is planned by 2020, this time, in contrast with the Apollo missions of the late 1960s and early 1970s, NASA plans to establish a base on the Moon where people will live for months at a time. Mr. Hill and Mr. Shaughnessy followed Dr. Koratkar's presentation, with a talk about the history of lunar exploration, from the ancients to today. At the end of the presentation they gave the teachers an update on NASA's current plans for future space missions.


After a delicious lunch, the participants were asked to form two teams of 4 people each. Each team was tasked to use a robot to explore the Moon and collect a lunar rock sample for analysis. The two robots were role played by Laurie Cook and Flavio Mendez. Since both robots were blindfolded, they had to depend completely in the instructions delivered by their team members. All instructions for movement of the robots had to be delivered in two-to-three short sentences, like "move two steps forward, turn right 90 degrees." The Moon in this activity was an area outside the symposium room were different obstacles, like chairs and tables, were placed for the robots to navigate. The activity was an excellent team activity with different roles for each member of the team. One person from each team was responsible for drawing a detailed map of the obstacle course. Two people were responsible for calibrating the robots and developing the robots' commands. The last person in the team was responsible for communicating with the robot. The two teams did a great job working together and making sure their robots navigated safely through the hostile terrain. While the robots were outside the room walking through the obstacle course, all participants could monitor their work via a webcam that was focused on the robots' movements, simulating mission control. Symposium participants use a web cam to monitor the robots' movements outside the room


The symposium concluded with a discussion about the activities and their application in the classroom. Participants were also invited to attend four related web seminars scheduled to take place in November, 2006. All participants received educational materials from NASA and a certificate from NSTA stating the number of hours of participation.
