Time to lend NASA a hand

Problem: What units do we use to signify liquid volume, dry volume, temperature, time, density, & mass.

Hypothesis: (when applicable) ____________________________________________________

Materials: 13 station samples (with the appropriate devices to measure them), clipboard, pencil, 2 brains

Background: O.K. NASA has been really busy exploring Mars and other wonders of the universe. They have been getting so many samples from Mars that they haven't had time to explore all their samples. They have asked for our help.

Procedure: You will find these samples at twelve different stations around the room. When your teacher signals you will go to a lab station and follow the directions given at each station. Don't spill any of the samples, this will hurt your results as well as the groups that follow you. You will have 5 minutes at each station. Make sure to use the measuring equipment provided at each station. Place your data in the box provided on this paper. It is of great importance that you label your measurement properly (ml, g), without this information NASA can not use your data (use the data table provided below). The measuring equipment will help you in this process. If you have difficulty, raise your hand and your teacher will assist you. Remember NASA is counting on you. Good luck!
