Today we started class with how a boomerang works. I used a Powerpoint presentation by Tom Conally maker of Flying Frog Boomerangs. The presentation is titled “BOOMERANGS: Magic or Science?”. It explains Bernoulli’s Principle and gyroscopic precession. It also includes instruction on how to throw and catch a boomerang, effects of the wind and even a bit of history of boomerangs. It is a useful tool when doing classes such as this.
After learning about boomerangs we got to have some fun. Each student got to decorate a Roomerang (thanks to Gary Broadbent) and bend airfoils into it. We then headed to the building’s lobby to test out the boomerangs.
Next we switched gears and started reading stories from the Aboriginal Dreaming. Todays story was “How the Sun was Made” a story whinh included a large emu egg (are there any other size?) being thrown int the sky, landing on a fire and the yolk glowing in the night creating daytime. We finished class by watching the video of Yothu Yindi performing their song “Treaty” and discussing what it meant.
My assistant, Hector, demonstrated how to make and launch paper “flicker rangs”. The students were sent back to school with the Dreamtime story, and plans for both Flicker rangs and a cereal box boomerang.
