Name: Kruthik Ravikanti Water Lab Modified Lab and Informal Report I am modifying the requirements for this lab. You DO NOT have to turn in a formal lab report. Please complete the following lab sheet as an informal lab report. Introduction: This lab will give you the opportunity to review some of the characteristics of water you have just reviewed: surface tension, cohesiveness, universal solvent, capillary action, high heat of vaporization, high specific heat, and unique density. You will complete several mini-experiments to investigate these properties of water. Use this modified lab sheet to help you complete the lab and report your data. Submit this document to the “Water Lab” dropbox when you are done. Below you will read and complete several trials which will allow you to investigate the properties of water. You will use your understanding of water to define and observe the properties of water and provide one example of an impact that each property has on living systems (cell or organism). Materials (all parts) glass jar (baby food jars work great) 3 plastic cups ice needle (or light paper clip) clear straw of small diameter clear straw of large diameter oil 6 tablespoons of salt Instructions: Each trial will allow you to observe or think about one property of water. Perform each one by following directions carefully. I have added highlighted help to each section. Please edit and/or remove the highlighted help before submitting this informal lab report . Trial 1 Materials: plastic cup ice cube Procedure: 1. Fill up a plastic cup half way with water. 2. Place an ice cube in the water. Analysis Questions: 1. What happened to the ice cube when you placed it in the cup of water (did it sink or float)?
2. Most substances get continually denser as their temperature is reduced. Is that the case with water? 3. Explain the actions of the ice cube in your experiment by identifying property of water and
describing what is happening at a chemical level.
