2.2 Report Sheet_Meteorite or MeteorWrong_V2

Names:________________________________________ Section:______________ Group #_________ ASTR161 Fall2021 Report Sheet: Meteorite or MeteorWrong a. Determine whether or not your sample is attracted to a magnet while it is dry. b. Check the sample visually for features of a meteorite. c. Find the mass of the sample while it is dry. d. Find the volume of the sample. Tie a string around your sample and suspend it in the beaker, fully submerged but not touching the bottom or sides. Record the scale reading in grams. e. Calculate the density of the sample. f. Based on your calculated density, determine that the sample is a possible meteorite type or an Earth rock. Use the density chart provided on page 4. g. If available, perform a chemical test for the presence of Nickel. sample Mass of dry sample (grams) Scale reading (grams) Sample suspend Volume of sample (cm 3 ) Density of sample (grams/cm 3 ) Calculate Possible type of meteorite base on density Attracted by a magnet? None Weak Nickel Test If available None Negative blue green red ZAG ------- ------- -------- 3.40 orange yellow purple black white NOTE: There is no single test that proves a rock is a meteorite—this is an exercise in combining the results of many different measurements to reach a preliminary conclusion. 1
