'What we did' on Friday 13 January 2012Our main subject matter for the evening was 'Extremes'
During the evening the following demonstration and interactive experiements took place.
EXTREMES from - 78.2 c (-108.7F) to + approx 473 C (883F)
A DEMONSTRATION with DRY ICE in its varying displays when in warm water, with added food colouring. Dry Ice sublimes at -78.2C
A DEMONSTRATION of burning a small piece of Magnesium Ribbon which displays an itense white light. Magnesium Ribbons burns at approx 473C
INTERACTIVE - Air presure - Holding a glass tumbler upside down full of water supported only by a piece of cardboard. Demonstrating the efefct of air pressure and surface tension.
INTERACTIVE - Exploring the magic of polymers with simple household materials. Who would have thought that a combination of a plastic bag, some water and a few pencils would produce such a simple dramatic experiment. We learnt how to poke a hole in a plastic bag filled with water and reseal it like magic. The secret has to do with a better understanding of the chemistry of polymers.
Quote from Steve Spangler.
INTERACTIVE - During the Science Club evening in December we touched on the science
of 'Codes' and 'Code Breaking'. During this club children learnt how to 'send and receive' a hidden code, each had a 'Cipher Wheel'. See more detail in December's report - Click here
A DEMONSTRATION - Touching the science of 3D. Each child was given a pair of 3D glasses to watch a specially made movie - oncluding visiting a castle, space, a garden,
flying over the Alps mountain range.
The January issue of 'making science cool' booklet was handed out
- click here to see pdf copy or if children absent the booklet was posted.
In all a fantastic evening for children and helpers
