Building a Hovercraft Science Project
February 25, 2013Look, Mom, No Wheels! Building a Hovercraft Science Project
by: Norm Barstow
The first practical design of the hovercraft was completed in the late 1950’s by British engineer, Sir Christopher Cockerell. Since then, the continued development of this invention has been ongoing, and currently, the hovercraft is being used commercially, by the military, and for personal use. Teachers have been constructing versions of the hovercraft using balloons, film canisters and flat materials in classrooms for years.

Surface Tension Demonstrations

We Water Molecules Stick Together! | Surface Tension Demonstrations
by: Tami O’Connor
I am a believer that observing discrepant events burns concepts into students’ memories far longer than simply reading the facts of the lesson from a text book. A few years ago I was designing a unit on surface tension. Because so many awesome hands-on activities deal with this topic, my greatest problem was picking and choosing! In this blog, I will describe one of my students’ favorite surface tension demonstrations. It teaches about surface tension and capillary action.

Bernoulli’s Principle: a Lesson or Two Made Out of Thin Air
November 25, 2012by: Tami O’Connor
A few weeks ago my daughter, a new fifth grade teacher, asked me to come into her school to present a hands-on science lesson on Bernoulli’s Principle. Nothing delights me more than working with kids in a classroom. After 16 years of teaching, it’s hard to be away from it. At first I was unsure what I was going to bring in. I have so many really neat activities at my disposal that it is difficult to select just one. I finally narrowed it down to activities dealing with air pressure, which is part of their curriculum (always a plus!).
As I rummaged through the office, I unearthed my supply of funnels, flex straws, and ping pong balls and decided that Daniel Bernoulli would be my guest of honor that day. When I started my lesson, I blew up a balloon and talked about air and its properties. Inviting comments, I discovered that they had some very interesting background knowledge, and most of it was correct… Read the rest of this entry »
