Students will determine the differences in density of three samples of water: ice, hot, and salt saturated. cooking oil, one graduated cylinder, three different food colors.īased upon prior knowledge, students will be asked to describe ocean water using the "Five Es": Engage, Explore, Explain, Expand, and Evaluate. Insert the clay roll into two cm of the bottom of the straw. Using a black fin-tip marker, mark lines every cm from the bottom of the straw to the top. Density straw for each tub: cut a straw in half.
