Kindergarten and 4th Graders mining science lab.
Mrs. Klein's kindergarten and Mrs. Brozovich's 4th grade have been studying rocks and minerals. The two classes got together on April 12th for a mining science lab. The question was "How do miner's know where to mine?" The students hypothesized that someone found a valuable mineral nearby. This led to the discussion of miner's using rock drills to drill core samples in order to find where the ore is located. Students were then given a circle drawn on a piece of paper and instructions to divide their circle into four pieces. Then they were given cake with brown frosting that was in the shape of a circle and they were told to lightly divide their cake into 4 pieces by drawing through the frosting with a knife. Next the students were given clear straws that were 2 inches long. The straws were their rock drills. With each sample they had to make a mark on their paper circle in the correct location. If they came out with white cake they marked the spot with a circle and if the sample came out with red cake they marked the spot on the paper with an x. When they were done drilling they had to draw around where they thought the ore was located to indicate where the mine should be. The last step was to turn the cakes upside down and compare their drawings with their cake. The students had a good time learning about mining and core sampling.
