Adi on LAB Properties of New Materials objectives Predict the properties of a material. Determine possible uses for a material. Background: This substance is fun to play with But how do you describe its properties? Question: What are the properties of this new material and what can it be used for? Preparation Materials white glue borax laundry soap warm water 250-ml beaker or cup 100-ml beaker or cup graduated cylinder craft stick for mixing 4. Put 5 mL of water and 10 mL of white glue into the smaller beaker and mix completely. 5. Add 5 mL of the borax solution to the glue solu- tion and continue mixing for a couple of minutes. 6. When the substance firms up, remove it from the container and continue to mix it by pressing with your fingers until it is like soft clay. 7. Examine the properties of this material and record them in your data table. Safety Precautions CHONE- Procedure 1. Read the procedure and safety information, and complete the lab form. 2. Prepare a data table to record your observations of the following: stretched slowly, stretched quickly, rolled into a ball and left alone, pressed onto newspaper ink, dropped on a hard surface. 3. Put about 100 mL of warm water in the larger beaker and add borax laundry soap until soap no longer dissolves. Conclude and Apply 1. Identify the properties of this material. Is your material a polymer? How do you know? 2. Evaluate Based on the properties of the material, what do you think it could be used for? How could the properties be modified? COMMUNICATE YOUR DATA Create Name your product and prepare an advertisement with text and graphics. Share your advertisement with other students in your class. Chap 3d Lab 759 ?

Place the ground sugar cubes into a medium-sinad glass, and place two unground sugar cubes into a similar glass. 4. Add an equal amount of water at room temperature to each glass. 5. Do not disturb the glasses. Observe the amount of time it takes for the sugar to dissolve.
