List the materials that will be on hand for their experiment and the need for careful measurements, observations and recording of data. Each team will need to construct a data table and formulate a procedure for conducting a well-controlled scientific investigation. Vocabulary atmosphere conclusions hypothesis petri dish procedure observations Scientific Method spectrometer Explore Procedure 1. Complete Teacher Demo as described above. Allow time for each Mars Mission Team to design an experiment that tests 3 different methods of separating magnetic substances from the four samples of Martian soil.
All teams complete their experiments, recording data and preparing a lab report.
Individual teams report findings and results to class. Prepare a soil sample that contains a known amount of magnetic material. Try various collection methods and weigh the amount of magnetic material collected with each method. Examine the separated magnetic substance with a hand lens. Repeat the experiment a few times.
