Teachers Making a Difference – Mrs. Z and her Oobleck Pool of Goo

Some teachers teach from the book and others make learning come alive. Judie Zoromski, or Mrs. Z,  (say it fast and she’s called Mizzy), teaches science at Mary, Seat of Wisdom Grade School in Park Ridge, Illinois.

She is one of those teachers who gets it home to the dinner table. Her Friday Finale lessons make the “kids and their families live science.”

Mrs. Z taught for six years then took some time off to raise a daughter. When she went back to the classroom, she taught second grade for two years, fifth grade for two years and then “landed” in junior high science. She teaches 7th grade biology and 8th grade physics and chemistry.

She describes herself by saying, “as a person and a teacher I like to bring things to life and create a lot of excitement.”

When taking the science teaching job, Mrs. Z didn’t sit down and start writing out lesson plans, instead she looked for ways to make an impact on her students’ lives. In her research, she discovered our website, SteveSpanglerScience.com and from that Mrs.

Non-Newtonian Glop – Making Cornstarch Monsters

What do you get when you combine water, cornstarch, an amplifier and a speaker? (Besides a mess.)  You make cornstarch monsters.

Depending on the frequency played through the speaker and the vibrations it makes, the cornstarch will move and dance. Cornstarch is a non-Newtonian fluid which means it becomes a solid when it is under stress and a liquid when it flows. The trick is to find the right frequency that makes the best vibrations to move the cornstarch. You can actually see the sound.

This is a fun activity to take to a friend’s house and borrow their stereo equipment. For more on Cornstarch Monsters, read the experiment.
