Soluble or Insoluble? You will be testing some solids to investigate which are soluble and which are insoluble. Method 1. Half fill a transparent container with cold water from the tap. 1. Add a teaspoon of your first solid to your container and stir well. 2. Look at your water and see if the solid has dissolved or not. 3. Record results in your table. 4. Empty your container and wash out before you test your next solid. ENHANCING PRIMARY SCIENCE
