For the Science Fair, Alyssa designs an experiment to learn about erosion. First, she sets up three long trays with equal-sized piles of sand at one end of each tray. Then she sets up Tray A so that it lays flat on a table. She elevates the end of Tray B that holds the sand by 5 cm (centimeters). Next, she elevates the end of Tray C that holds the sand by 10 cm. Alyssa slowly pours 200 mL (milliliters) of water onto the sand in each tray. Finally, she observes and measures how far sand is carried by the water poured into each tray. What is the independent variable?
What is the height of the trays.
