1. Planning Steps for Investigation:
- Step 1: Gather the necessary materials for the investigation, including iodine solution, starch powder, and containers for mixing.
- Step 2: Prepare the solutions by mixing the iodine with water to make the iodine solution and ensuring the starch powder is finely ground.
2. Hypothesis for Investigation:
- The hypothesis for this investigation would be that when starch powder is added to iodine solution, the color of the solution will change to blue-black. This assumption is based on the known property of iodine acting as a starch indicator, producing a characteristic blue-black color when combined with starch molecules.
