WEST MIDDLE SCHOOL welcomes Plastivan presentation

Eureka! On March 21 and 24, Ms. Elizabeth Egan came to present at West Middle School. Ms. Egan is a representative of Plastivan. 

Plastivan is a program sponsored by the Society of Plastics Engineers. Her goal was to teach seventh-grade science students how plastics were discovered, made and developed. 

     

Ms. Egan demonstrated how molymers are linked together to form a variety of polymers. These polymers today go by different names such as nylon, rayon and what is known as Saran. Combining the variety of polymers create both physical and chemical changes. Some combinations create extothermic reactions, while others create endothermic reactions.

The science students were directed to combine chemicals to create the absorbent material found in diapers. Another activity had students combining polyvinyl alcohol and borax at a one-to-two ratio. This reaction forms a substance very similar to hair gel.

Lastly, Ms. Egan explained that polymers are linked together in chains much like spaghetti. These spaghetti-like polymer chains can be found in balloons. Next, Ms. Egan directed the students to blow up a balloon. Then rub a skewer with lotion. Amazingly, the students were able to manipulate the polymers and move the skewer through two opposite points on the balloon.

     

Our shoes, clothes, cars, appliances, furniture and so much more are made in large part of plastics. Plastics are shapable, bendable and moldable. These properties make plastics indispensable in every aspect of the products we use everyday.

Due to Ms. Egan, who is a packaging engineer, many of our students may now pursue the very interesting and lucrative career of plastics or package engineering. Ms. Egan encouraged students to continue their math and science education.  No matter where life takes us these disciplines are invaluable.

Kudos to Ms. Egan for her information and encouragement. Her hands-on activities have made a lasting impression on how plastics has transformed and improved our quality of life in the areas of transportation, medicine, entertainment and beyond.
