We learned the difference between independent and dependent variables with our penny and water experiment. The dependent variable in this experiment was the number of drops of liquid a coin could hold. We changed some of the independent variables up to see how they would affect dependent variable. We tried different coins (instead of a penny we used dimes, quarters, and nickels), different liquids (oil or vinegar), and smaller droppers.
