Wh8th grade Science: The Recycling Factory Science Project?
The Conveyor belt will transfer the material from the truck. The large magnests will pick out the bits of steel because it is magnetic. Then, the conveyor belt will go into the first water tank and all the plastic will float to the top because the plastic is less dense than water. Then the skimmers will skim it out. The conveyor will move it to the sugar water tank and the gl will float to the top because gl is only 1.4 density and the water is 1.5 density. the skimmers will skim off the gl and the remaining product is the Aluminum.
