Ice Experiment What happens when a cube of ice is put in cold water and warm water. Plan the practical Write a prediction Record the results Write a conclusion

Plan the experiment Write a method Pour 100ml of water into each beaker. Take the temperature of the water. Get the stop watch ready. Put in the ice cubes. Record how long it takes for the ice to melt.

Record the results Hot water Cold water Temperature of water (°C) Time taken for cube to melt (sec)

Write a conclusion What happened? Be specific. Think about what you have measured and make sure these appear in your conclusion.

My Conclusion The green ice cube took longer to melt in the cold water (** sec) and melted quicker in the fast water (** sec). An increase in the temperature of the water increases the speed that ice melts in water.
