Make a prediction about what each type of ice will do to the level of water in a container. Context Audience This hands-on experiment is suited for many different audiences and can be used to achieve a wealth […] The ice starts to melt, making liquid water. Salt dissolves in the water, adding ions that increase the temperature at which the water could re-freeze. Have each student complete their own “Melting ice experiment” worksheet. Add a few ice cubes to the glass of water. The salt lowers the freezing point of water. For this experiment, you are going to need a glass of water, ice, a string, and salt. 2. Fill a 400 mL beaker 1/3 full with ice, then add 100 mL of tap water. Discover whether ice melts faster in hot or cold water with our fishing activity. Then build a model to compare what you predicted to what you observe. As the ice melts, energy is drawn from the water, making it colder. Seek an adult’s help when using hot water. As an experiment, fill a sink with 5 or 6 inches of water and note the water level. There are endless different ways to explore ice and melting, and all make a great winter science experiment. Explore how melting of ice cubes floating in water is influenced by the salinity of the water. Experiment 2 PROCEDURE Part I: Freezing 1. When the ice cube melts, the level of the water stays about the same. The experimentally determined value for heat of fusion … Give each group the “Melting ice experiment” handout and review the set up. But it makes a difference whether that melting ice is on land or in the sea. Put 5 mL of distilled water into your largest test tube and use a utility clamp to fasten the test tube to a ring stand. The experiment proves that the amount of surface area makes the ice cube melt faster, but what if you tried different ways to melt the ice cubes? Melting Ice & Salt Science Experiment. Important oceanographic concepts like density and density driven currents are visualized and can be discussed on the basis of this experiment. Fill your glass 3/4 with water. Wait about a minute or so and then lift the string out of the water. We can demonstrate regelation by looping a fine wire around a block of ice, with a heavy weight attached to it. Experiment 4-Heat of Fusion and Melting Ice Experiment In this lab, the heat of fusion for water will be determined by monitoring the temperature changes while a known mass of ice melts in a cup of water. Alternatively, give students various materials and challenge them to design their own experiment to test the effects of melting ice on rising sea levels. Repeat this experiment by trying techniques like melting the ice cubes in hot water. Global warming - Global warming - Ice melt and sea level rise: A warming climate holds important implications for other aspects of the global environment. Next, lay a piece of string on the ice cubes and sprinkle salt over the string. If you place water and an ice cube in a cup so that the cup is entirely full to the brim, what happens to the level of water as the ice melts? This is an experiment you can confirm at home by watching ice cubes melt in a glass of water. When water freezes to make ice it expands and takes up more space than it does as liquid water (that’s why water pipes sometimes burst during cold winters). There’s zero net change in water levels there. The weight of that ice displaces the same amount of water it would displace were it to melt and intermix. Salt And Ice Experiment. The pressure exerted on the ice slowly melts it locally, … A crescent-shaped cube will melt the slowest. Firstly, how about trying a super simple melting activity to learn about changes of state. Because of the slow process of heat diffusion in water, the world’s oceans are likely to continue to warm for several centuries in response to increases in greenhouse concentrations that have taken place so far. The water from the ice takes up less space than the ice itself. Experiment. This is such a fun and beautiful activity! You might have heard that melting ice contributes to sea level rise.
