Water & Dye Exploration Lab

Water & Dye Exploration

Part 1: Observation

          Make observations about the water in both beakers with your partner. Make at least four observations. Record them in your composition book.

Part 2: Hypothesis

          Two drops of dye will be placed in each of the beakers. What do you think will happen when these are placed in the beakers? Think about that there are molecules of water and dye and discuss with your partner. Write down your hypothesis of what will happen in each of the separate beakers.

Part 3: Observation

          Make detailed observations with your partner after what happened when the dye was placed in the beakers. You can make more measurements and you may use your phone to time if you would like. Write down at least four observations and record them in your composition book.

Part 4: Explanation

          Discuss with your partner about why the dye and water acted differently in the cold water versus the hot water. Remember this is chemistry class and use what you have learned in your explanation about molecules.  Record your explanation in your book.
