1 FREEZING POINT LAB Name Date MATERIALS: (per group of 4 students) ml beakers ml beaker 4 - #2 test tubes Test tube rack Ice crushed (enough to fill a 1000 ml beaker) 4 - Thermometers (Celsius) 1-3 oz. Plastic cup Rock salt ( 50 grams) Antifreeze (30 ml) Water (30 ml) Stopwatch (per student) 2 sheets graph paper Colored pencils (1 red and 1 blue) (per class) ice chest bucket PROCEDURE: 1. Each person in your group selects either the letter A, B, C, or D. The letter selected will correlate to the following four duties. A = water in test tube with ice only in beaker B = water in test tube with ice and rock salt in beaker C = antifreeze in test tube with ice only in beaker D = antifreeze in test tube with ice and rock salt in beaker 2. In your test tube rack you will find four test tubes. Two will have water in them and two will have antifreeze in them. Also, each one has a thermometer in it. 3. One person from your group will bring the 1000 ml beaker to the ice chest and fill the beaker with ice. Then return to your group and place the beaker on the table. 4. Select one of the test tubes according to your duty (A, B, C, or D). Look at the thermometer and record the temperature on your DATA CHART for the Initial Temperature Reading (time = 0 on DATA CHART). 5. Complete the following steps: Each person will follow according to their duty selected. CAREFULLY place the test tube in the center of one of the 250 ml beakers. (Note: the thermometer is still in the test tube.)

2 The ice that is in the 1000 ml beaker will be divided into the four beakers. (Note: do not eat the ice nor put it in the test tube.) If you have ever made homemade ice cream then the test tube will be in the center of the beaker like the container is in the bucket. Then you will place your portion of ice around the test tube just like it would be done around the container in the bucket. Rock salt will be added to the top of the ice for duties B and D. 6. As soon as you have your setup completed begin recording the temperature every thirty seconds (0.5 minutes) for ten minutes. Record on DATA CHART. Fill in only the column for your duty. You will collect the other data at the end of the lab. 7. During the ten minutes your teacher will come by and put 500 ml of water in your 1000 ml beaker. 8. At the end of the ten minutes you will need to carefully remove the test tube from the beaker and set in the 1000 ml beaker. DO NOT remove the thermometer. During this activity the liquid in your test tube may freeze. By setting the test tube in the beaker of water you allow it to thaw. Otherwise if you try to pull the thermometer out it will break. 9. Those students who only had ice in their beakers may pour the ice in the sink. 10. Those students who had ice and rock salt will need to pour this in the bucket provided. 11. Rinse out 250 ml beakers, dry off outside and put back in container or area where you received them. 12. Each person removes their test tube from 1000 ml beaker, wipe off outside and place in test tube rack. 13. Return all materials to assigned area and make sure tables/work areas are clean and dry. 14. Share data collected with other members of your group. 15. Graph water & ice (red colored pencil) and antifreeze & ice (blue colored pencil) on one sheet of graph paper. Graph water, ice & rock salt (red colored pencil) and antifreeze, ice & rock salt (blue colored pencil) on a second sheet of graph paper.

SC.A know that the average kinetic energy of the atoms or molecules of different objects varies with their temperature. SC.A understands that changes in energy cause phase changes. K W What do you KNOW? What do you WANT to know? 1. What are the four phases of matter? L What did you LEARN? 2. What is the movement of molecules at each of these four phases? 3. Diagram the space between molecules in the four 4. What does adding heat to an object do to its phase of matter? 5. What does taking heat away from an object do to its phase of matter? 6.
