Earth Science Grade 10
Step 1: The materials are put on a conveyor belt with strong magnets hanging above it. The magnets pick up the steel can pieces. They are picked up because they have iron in them. Then the workers remove the steel can pieces and separate them from the others.
Step 2: The materials remaining are milk jugs, aluminum soda cans, and soda bottles. The next step involves the large water tank and nets for skimming the materials out of the bottom of the tank. Next, I simply put the rest of the materials in the tank. The only material that should float should be the milk jugs because they are less dense than the water. The milk jugs are 0.9 grams per cubic centimeter, the water is 1 gram per cubic centimeter. The aluminum soda cans and soda bottles sink because they are more dense than water. The aluminum soda cans are 2.7 grams per cubic centimeter and the soda bottles are 1.4 grams per cubic centimeter. If an object is more than 1.00 grams per cubic centimeter it will sink. If an object is under 1.00 grams per cubic centimeter it will float. The workers then take out the milk jugs floating above the water with their skimmers.
Step 3: The remaining materials are aluminum soda cans and soda bottles. The next step involves the concentrated sugar water, which has a density of 1.5 grams per cubic centimeter. The aluminum soda cans and soda bottles are placed into the concentrated sugar water. The soda bottles should float because they are less dense than the concentrated sugar water. Soda bottles are 1.4 grams per cubic centimeter. The aluminum soda cans have a density of 2.7 grams per cubic centimeter which means they sink in the concentrated sugar water. The workers then skim out the soda bottles on the top of the concentrated sugar water and separate them from the aluminum soda cans in the bottom of the concentrated sugar water.
Step 4: Each of the different materials are placed into bins and are officially separated.
