Educational worksheets exploring how water temperature affects dissolving and identifying soluble vs. insoluble substances.

Two educational worksheets on a light green background. The left worksheet, titled "Does the temperature of water affect the speed of dissolving?", shows three beakers labeled cold water, warm water, and hot water, with space to record temperatures and times. The right worksheet, titled "Soluble or Insoluble - Does it dissolve?", features a table to classify materials like sand, chalk, and sugar as soluble or insoluble, with a green "ink saving Eco" label in the corner.
