Name How Thick Are? Directions: Read the question below and formulate your hypotheses. Then, use the provided materials to conduct the experiment. Make your observations, and draw your conclusions. Create a record of your experiment on a separate sheet of paper. Make sure to copy the table below to record your data. Question Which of the provided materials will be the most viscous, and which will be the least viscous? Hypothesis Formulate your hypotheses. (What are the answers to the questions?) Record your hypotheses. Experimental Design 1. Draw a line 1cm (0.4 in.) from the top of the whiteboard. This is your starting line. 2. Rest the whiteboard on a block or book so that it sits at an angle, and place paper towels at the bottom of the whiteboard to catch the liquids. 3. Fill one teaspoon with one of the liquids and set the stopwatch to zero. 4. Tip the teaspoon onto the starting line and start the stopwatch at the same time. 5. Record how long it takes for the liquid to run to the bottom of the board. 6. Repeat these instructions for each of the other liquids. Record the time it takes for the liquid to run to the bottom of the board each time. Observation What happened during your experiment? Record your observations. Liquid Time taken to run down ramp(s) Conclusion What is the answer to the question? Do your findings support your hypotheses? Which liquid is the thickest? How can you tell? What does this tell us about the viscosity of liquids? Are they all the same or different? Write your conclusion. Teacher Created Materials #12451 Matter Inquiry Handbook 35
Properties of Volume are fluids. This means that they can be poured. They easily change shape. They always become the shape of the container they are in. For example, the liquid in a milk carton is always the same shape as the carton. Even though liquids change shape, they always have the same volume. This is because of the arrangement of the particles in a liquid. The particles in a liquid are packed together quite tightly. This means that liquids cannot be compressed or forced into a smaller space. Their volume (the amount of space they take up) always stays the same. This is called a fixed volume. But, particles in liquids are able to move around. They are not in a fixed position. They can slide over each other. This is very useful when you are trying to pour a drink! Bonds Bonds hold the particles in a liquid together. These bonds are forces. In liquids, the forces are not strong enough to hold the particles in the same place. This is why liquids can change shape and solids cannot. Viscosity Viscosity is an important feature of liquids. Viscosity means how thick or runny a liquid is. Some liquids are very thick and sticky. They have high viscosity. Some liquids are very runny. They have low viscosity. Viscosity has to do with how the particles in a liquid affect each other s movement when they are poured. Forces between the particles affect how a liquid moves. Thick liquids move very slowly. They are made of particles that affect each other s movement a lot. Examples of this are corn syrup, molasses, and tar. Runny liquids move very quickly. They are made of particles that do not affect each other s movement a lot. An example of this is water. 36 #12451 Matter Inquiry Handbook Teacher Created Materials
