Reinforcing Hydrolysis and Dehydration Synthesis

Page 14 (Title this page “Gloop Lab”) Compare and contrast hydrolysis and dehydration synthesis. Your answer must be exactly 33 words.

Monomer / Polymer Kinesthetic Activity

Gloop Lab

Directions for making “gloop” *Decide on ONE “Materials Person” per table, this is the ONLY person allowed to leave the lab group* 1.Predict – same as partner. 2.Hypothesis – same as partner. 3.Observation A.In your beaker, add 10 ml of glue. B.Add 2-4 drops of food coloring to the glue and stir with wooden stirrer. 4.Draw a Diagram 1.Predict – same as partner. 2.Hypothesis – same as partner. 3.Observation A.Add 10mL of water (from the sink) to the beaker using the marked graduated cylinder and mix thoroughly. 4.Draw a Diagram 1.Predict – same as partner. 2.Hypothesis – same as partner. 3.Observation A.Add 4 drops periodically (at a time) of borax solution to the beaker using the plastic pipette and mix thoroughly until only a small amount of water is left. B.Rinse gloop with water and put in baggie. 4.Draw a Diagram Column – Glue + Food ColoringColumn – Add Borax SolutionColumn – Add Water Clean Up and Baggies (label with name and period and put in bin).

Questions Level 1 – Describe……. Level 2 – Explain……… Level 3 – Predict………. Summary must include these words- polymer hydrolysis dehydration synthesis Gloop Lab Page _________ Essential Question: Question Column Glue + Food Coloring Add WaterAdd Borax L1 – L2 – L3 – Prediction: Hypothesis: Observation: Diagram: Prediction: Hypothesis: Observation: Diagram: Prediction: Hypothesis: Observation: Diagram: Summary -

The glue contains a polymer called polyvinyl acetate resin. We changed the polymer’s behaviors twice in this activity; once when we added water and the second time when we added borax. Copy and answer the following questions (on back of lab notes) 1.When we added water, what process was occurring; dehydration synthesis or hydrolysis? Describe the glue after water was added. 2.When we added borax, what process was occurring; dehydration synthesis or hydrolysis? Describe the glue after borax was added.
