Learning Outcome
 Course Objectives Met:
 demonstrate the scientific method and principles by conducting an
experiment, collecting and analyzing data, and interpreting results.
 identify unifying principles and repeatable patterns in the physical
world and apply them to problems or issues of a scientific nature.
 NWACC Objectives
 Students can write clear, coherent, well-organized documents,
which are substantially free of errors.
 Students develop higher order thinking skills.
 Students can use computers proficiently
 Students can employ a variety of sources to locate, evaluate, and use
information
Project Overview
 We contacted Mrs. Van Pelt, a 6th grade Science
teacher at Old High Middle School in Bentonville, AR
 We presented our lesson plan to her 4th period 6th
grade science students
 Through this lesson plan, we taught the children about
non-newtonian polymers.
Teachers for a day!
What does Non-Newtonian Mean?
 Most fluids behave like water and honey, where their
temperature determines their viscosity, or the
resistance of that liquid.
 Non-Newtonian Fluids differ because it is not only
temperature, but the force being applied to them that
determines this resistance.
What is a Polymer?
 The Greek words “poly” and “meros” have been used to
give us the word polymer.
 Poly=many and Meros=parts
 Plastics are polymers, but polymers aren’t
always plastic, as is the case with these
substances.
Method
 We brought with us and allowed for hands-on experimentation
with Floam, Flubber, Silly Putty, Play-Doh, and Oobleck, each
being a non-newtonian polymer
 While we experimented, a short YouTube video was shown of
individuals running across a pool filled with Oobleck.
 Students were encouraged to squeeze, stretch, compress, draw
on, and experiment with these substances as they saw fit
 Recipes for each substance was a part of our presentation, in an
effort to call attention to the similarities of these polymers
 These recipes were then given to their teacher so that the
students could then have the opportunity to make them at
home
