What scientific question would you like to explore in your investigation? How will you investigate the answer to this question? What kind of test will you carry out? One idea for a test could be to drip water onto certain materials and then measure the mass of the remaining material to see how much solution has occurred. Another idea would be to set up a sloped tray of various mineral materials to see how dripping water causes erosion on a slope. Describe your idea. If it helps, include a drawing of your setup.
